Hey bud. I’m having the exact issue. Replaced the thermostat with whatever the parts store gave me and didn’t fix issue. Went to ford dealer and they entered my VIN and tried to give me the thermostat that the truck was built with. I had prior knowledge of the “updated” part with the plastic tip so I told him about that. He went in the back and got it for me. I believe the number is the same as the one you are posting about. Changed it yesterday and still didn’t help. What do you suggest now? I’m leaning towards replacing the water pump now just to see if it helps. Also I am using the orange coolant and I seen on another post that ppl are saying to use the yellow instead. Thoughts?
I have a 2018 XLT. After Cam Phaser replacement this is EXACTLY what was happening. I'd get on the highway at 75 to 80 mph and the engine would heat up. Not completely overheating, but it would heat up enough to raise eyebrows. Also, the electric fan was running almost constantly. It sounded like I was driving a jet airplane! After replacing the thermostat with the new, updated thermostat, this solved EVERYTHING. Running great now!
I’ve been learning so much from you. Thank you for passing your knowledge to others. I’m happy I’m not as uneducated as I used to be. I’m also grateful to have you as my friend. God has blessed me to have you as my friend. I’m always here for you too. Bless you
Excellent job going the distance to take care of the customer! In this case I felt it was the thermostat and pleasantly surprised to hear it was. I also learned some new information about the cooling systems in these newer trucks. Keep coming with the great information. Thank you! 😊 🐶
I really wish you were local to me, I dread taking my truck in the dealership for anything nowadays. You are the most dedicated Ford mechanic I've ever seen, Good work bud!
You're the best, Rich! Once again proving why you're an amazing person/mechanic - going above and beyond! Its great you truly have the customer in mind with each job. Thank you!
Thank you so much! Had this problem yesterday on my first leg of a 1200 mile drive. Stopped by a ford dealer, bought both parts and brought it in this morning to get replaced and a coolant flush. And voila! No problems whatsoever today. Even got better gas mileage!
Thanks Rich. Exact same thing occurred about a week after the cam phaser replacement on my 2018 F150. I noticed when cooling fans were running full speed. Dealer fixed it.
I had the same problem after my second timing chain replacement. Dealer changed the water pump, thermostat, and radiator and I still had the problem. Saw another video about the new design thermostat and then saw your video. Ordered the new parts and put it in two days ago. Temperature dropped at least 15 degrees and has not gone into the 220's yet. This appears to have fixed my problem. Thanks for this video. It showed the same problem that I had.
Good information. Remember I was asking you about that no spark but would crank no codes. It was on 5.4 F150. It turns out it was a bad PCM. Thanks for the help.
Great job! You are a vanishing breed. Your honesty and strait forward explanation sets you apart from most dealers. Wish I lived close to you. God Bless.
Thank you...My 2018 Raptor is going in for its 2nd round of cam phaser repairs. The first was at 47K and now again at 97K. Never had any problems with the eng. temps. However, knowing what you just shared, I'll talk with the tech and see if we can upgrade the thermostat. Much appreciated..
Been following you for awhile. I just wanted to say thanks for posting this. I have 2018 F150 3.5 with 48k. I had my passenger turbo replaced in December. Afterwards I noticed I was running hotter than usual. Just had my cam phasers finally replaced last week. Told the dealership that I had been running hot, above 230 unloaded. They said they road tested it and found no issue. My Ford pass app confirmed they only drive the truck 2 miles so I guess they really didn't care to review my concerns. After some research, I decided to install a new thermostat myself today. The problem is completely resolved. Thanks again!
I had the same situation almost exactly. After phasers we’re replaced on my 18 f150 this past winter, once the weather warmed up, it would consistently get warm and show a digital temp once it reached 228. I saw it get as high as 240ish once. (August at 75-80 mph) Dealer replaced the thermostat, gasket and housing. All good for now. Mileage was roughly 45,000. Thanks for the video!
That's a great tip! I've done several cam phaser jobs at my shop. I've always replaced the thermostat along with the repair and haven't experienced this problem. No I know about it and can use this information to solve overheating problems in the future. Thanks for the information.
When I had my 2017 (114K) at the dealership for Timing Set and Cam Phasers replaced due to start up rattle, I had them replace the thermostat, water pump, belts, and hoses since I’m keeping the Truck and it was at my Expense. July 2021 No Issues For me it was better to put the extra money while it was tore down and spend the extra money on parts and save some money on labor. Keep the great videos coming!! God Bless
Did you pay all out of pocket for repairs? My cam phasers seem to be going out and I’m sure I now have to pay out of pocket since I never did the recall 🤦🏻♂️
I’ve seen a pattern of aftermarket thermostats causing slight overheat condition along with the fans running. On the 5.0’s. I only put in O.E in them now.
Glad it got all sorted out. Sounds like the original design for the thermostat was not up to long term spec and the engineers designed a better thermostat for that engine. Continue to be awesome :)
I have also noticed since the cam phasers were replaced on my truck it has definitely run a bit hotter, fans running more often, even hitting 230 on occasions when driving up hills (not to the extent that your customer stated he had on the flats). I'm going to replace the thermostat and inspect it. My phasers were done end prior to the update in parts so it'll be interesting to see if I have the same wear marks. Thank you for caring enough to look further into the problem.
@@2WheelsdownN rubber diaphragm on the T-stat was torn. I replaced it with a 180F degree Tstat. Now under normal driving truck is at 185-195ish. Towing and hard driving it hits 205F highest temp probably 215F while towing our boat up hill to the lake. Mind you 215F was what I was running at under normal driving prior to replacing. I haven't heard my fans turn on since replacing so I'd say it was a success.
@@BlazeofFire524 that's great to hear brotha keep that ford going.im having a rattle on start ups when my truck sits over 2 or three weeks when we take the boat out .i got 178k on the dash.not sure if it's the phasers or timing chain Tensioner mind,it's 5.0 2011
Good fix ,thanks for the information, My 3.5 is so quiet as well you almost forgot it’s running, I had a 2017 f150 3.5 w tow package and it ran cooler towing than my new truck does , the only difference is my 2020 is a maxtow 3.5 . Both trucks 10 speed,3.55 4x4s, if anything it should run cooler towing but it doesn’t. It never got over 220 but I was only pulling 3500lbs and in 50 degree weather … my old truck could tow my loaded enclosed trailer in august at 90 degrees,with the ac blasting and never go over 212. I wonder if that updated thermostat would help my 2020. I only have 10k mikes on my 2020…thanks for the part numbers.
Nice work, I've found the same problem on lots of 17-20 F150s. Most are not even overheating but the customer complains of the Engine Fan running high/ loud more than usual. I've monitored the temp and found it runs near 10'C colder with a new thermostat installed, from near overheat to perfect Operating Temp. The Original Thermostats are pretty shitty when closely inspected, they wear and stick closed like u said not allowing full circulation when the engine needs it. The Fan's are so damn good that the thermostat has to be completely failed and the engine worked hard to overheat as the fans just ramp up speed as the temp increases and move a shit ton of air. I suspect most near 100 000kms could benefit from a new thermostat and the yellow coolant but most people don't have long enough drives or notice the fans. Probably that nasty Pink/ Orange coolant that made em fail in the first place.
Which brand thermostat? I just bought a 2018 3.5 ecoboost with 36k miles and I got p0018 and p0021 the 2nd week I owned it and then the CEL went off and the fans have been running hard since then, supposed to be going to a Ford near me since I bought it 3 hours away. Fml
@@joelexline9 Just Oem from the dealer, thhe part numbers are constantly updated for parts that are shitty. As for the Cam codes, kinda odd for the second gen eco to actually set cam codes if its full of clean/ proper oil and somebody hasn't messed up changing the VCT gears. If the Fans Roar all the time and full of coolant its probably not overheating. The same Gens have a common AC problem that causes the Fans the run high. If they start roaring after driving/ high loads, Probably thermostat. Can monitor Temps with Scan tool.
Well jobber thermostats are only about 50 percent bad out the box, glad you figured it out sometimes we have such things show up to are shop they really get the thinking going
At least some of us actually care about taking care of the customers, doing our level best to avoid repeated comebacks. I have taken customer vehicles home overnight. I live kinda far from work and besides verifying my repairs I can get a feel for the car and listen for anything else they may be unhappy about, wind noise, dash rattles, brake pulsation, etc
Just had one in the shop 2 weeks ago with cooling fan running on high after tech did phasers. Replaced thermostat and re bleed cooling system. Fixed. This will be the 5-6 one that we’ve had to replace thermostat in directly after replacing phasers
What you have described is exactly the issue I had on my 2018 after phaser replacement. My truck would not get hot enough to go into power reduction mode , but would get close while towing. Ford told me it was normal. I knew it wasn't. The dealer and Ford refused to do anything about it, so I took it to a Lincoln dealer (other Ford dealers refused to repair it even if I paid) and the Lincoln dealer flushed and filled the system with a thermostat replacement. Everything is back to normal. Ford now refuses to reimburse me for any repair despite having video evidence of before and after.
It's incredibly frustrating. I was trying to proactively prevent a bigger issue and/or excessive wear and tear on cooling fans and other components. Unfortunately the tech working on my truck wasn't as observant as you. Your video will help a lot of owners. Thank you!
Had my phasers replaced and had several issues after. The main one being the solenoid that controls the blinds that open and close on the grill was put together incorrectly. I was driving around with no air flow coming into the engine and the coolant started to boil and foam. Temps were not out of spec either.
I had this same problem after my local dealership replaced the cam phasers in my 18 raptor. I put a SPD performance thermostat in it and that solved the problem.
I got a 2018 with 95k on it how would I know if I have to do cam phasers? Thing runs great I'd rather not mess with what's not broken I change my oil every 3 to 5k
I had cam phasers done on my 2018 and I have this issue. They did replace the thermostat because I immediately complained. They assured me it’s normal (2 dealerships) and on the highway I run at 230-240. Right after the repair I was even hitting 250 if I ran at 55mph (low rpm in 10th gear seemed to make it even worse). I hit over 250F with ambient at -5F! I’ll be running by my dealership this week and showing them this video. Been dealing with this issue for a year.
@@2WheelsdownN I installed the new part number and i am back down to my original numbers! After warm up, I sit at 207/208 while cruising, and when I am at a stop light, I drop down to 198! I have not been on the highway yet, but just smashing the gas, I can get up to the mid 220s, but it immediately drops down to 208 again when out of boost. So awesome to not hear my fans screaming all the time!!!!
My 2018 ecoboost over heats if I tow my large trailer only at a certain speed and after driving 30 to 45 miles slow down alittle its fine. Think its the intercooler not getting enough air because of the shutter vents. I'll check my thermastat and go ahead and replace it with the newer style to be safe. Thanks 👍
Thanks for sharing there is a new version of the thermstat. What is not clear, why does it only happen after the phaser job, when the thermostat was fine previously?
Gotta love "updated part numbers" which you don't know about.... Was there a TSB for this? It doesn't sound like a comeback, you did good man! Love the videos as always!
I think this is what was happening to my 2018 Expedition. Same issue of temp got up just a little. Dealer couldn’t find an issue. 3 days later while on vacation temperature suddenly goes through the roof and overheat warning went off. Pop the hood and coolant is all over the engine. The inlet and outlet hose were blown along with thermometer. Wish I had seen this earlier. It may have prevented a major headache, tow, and larger repair cost. Needless to say, I’m done with my dealer as I’ve seen several posts about it, and apparently Ford is aware of this issue.
My 16, F-150 has been at NTB for over a week now. I took it in for….AC stop blowing cold air, high temp & message on dash was “power reducing”. They said i would need to replace the water pump, thermostat, O-rings, gaskets and belt. I agreed since I’m at 150k so I wanted to be preventative and just do it. Now 9 days later they still don’t have this fixed. Would it be in bad taste to recommend they check the part number on the new thermostat? I don’t want anyone telling me how to do my job especially when they are not an I.T. person but I really need my truck fixed and back on the road to get to and from work. They have said it was probably air bubble, potentially a cracked block, sensors and different pressure tests.
Thank you for all you do i have a 2018 3.5 eco with around 49,000 on it. I just got my truck back from doing the phasers and saw this happen once and it was at 226 only popped up for a second. I was pulling a really small trailer but don't think I was going over 60. On my trip back nothing and I was going over speeds of 65 some of the way. I don't drive my truck much but I'm taking it to Ohio in August which is an 900 mile trip for me one way should I replace my thermostat or could it just have been an air pocket. My reservoir was on the low mark when i got it back i did fill it to the correct level. Should I take it for a run on the highway and do some tests thank you so much for your help.
@@FordBossMe it did come back when I was pulling a 5x8 trailer 3 times it goes to 236 then goes down quickly is there a tsb on this I want to call ford tomorrow and was this caused by getting the phasers done.
Any chance you're located near Modesto, CA? If so which Ford dealer are you at cause I want to bring my truck to you from now on. You're absolutely awesome!
I never had a temperature issue in my truck. I only saw 225-228 degrees when towing up long grades on the highway. I had my coolant flushed and thermostat replaced by the dealer. Now the truck runs way hotter with and without the trailer. I normally see 230 on a slight incline no trailer. When towing I often lock it in 7th gear on climbs to maintain 230 degrees. I took it back to the dealer they said everything is fine and “that’s just how these trucks run” 2020 ford raptor. Wish I had a tech like you.
Do you recommend changing to the new thermostat even if your not really having a problem? I've only had my 2018 F150 3.5 get hot one time and that was when I was pulling my travel trailer up hill. It did surprise me though because I had went up other hills on that trip with no problems.
Hey man, I have a 2018 F150 5.0. I've got what I believe is a VCT phasers rattle at partial throttle when deceleration when the engine is cold. I have had the TSB 18-2354 done, but it still does it. Any thoughts on this? or just drive it till the wheels fall off. Thumbs up! Thanks for your service and your videos!
We have a used 2017 F150 that we have this condition on. I've been battling it for a while. Started as consuming coolant and overheat, it was leaking water pump. Shop assured me they used Motorcraft parts upon my request and filled under vacuum, including parts you listed. I still have an overheat like that, I bought a new thermostat and will put it in (from what I've read they tend to fail out of the box sometimes). If that's not it, what else could it be? I don't think the cam phasers were done on our particular one. It's a Platinum, so should be gen 2 of that 3.5 Ecoboost.
Hi Ford Boss Me, I see you hearted my comment, but I was wondering if you would be able to respond? I tried to look on your channel but there's no contact info. I'm getting spikes of temps and now back to slowly losing coolant (about 1.5-2" on the overflow tank, both pictures taken when engine was cold). I love this truck, but am getting incredibly desperate, not sure if I can throw $6-8k for a head gasket at this.
think I'm going to try and put and updated thermostat in, but ill run my scenario by you and see what you think...used to turn wrenches years ago. Made a career change and moved on from that life. Still can do the work but I tend to have an old colleague, ( ASE MT) handle most of my issues now... Had the 17 f150 3.5 down to him for rear pinion seal replacement and to search for coolant leak. He replaced thermostat and seal with the one I supplied him with (not OEM). Prior to him getting the truck I did have a low coolant situation, but couldn't find an obvious leak and had temps climbing into the 230's+. As I said, he replaced the parts I supplied him with and I'm still getting temp spikes at highway speeds, in 10th gear mainly AFTER I let off the accelerator. IE cruise control up the highway at 75mph, 10th gear, and cancel the cruise control as I'm approaching my exit. Temp numbers will appear over temp gauge, 226-230+. Cam Phasers have NOT been done, but need to be. 100K miles on truck, all stock. Thoughts? Thanks for everything you do for us on here. Your videos have helped many of us out, more then once! God bless
I'd like to share a concern with Degas Bottles on 3.7 in PIU . Where small hose attaches to Gegas Bottle there is a sleeve in that fitting. On High Mileage Police Car Sleeve will move towards Degas Bottle and block off flow. I found it because the cooling system could not self bleed air on top of coolant in Degas Bottle. A small Search and Destroy on Old Bottle Confirmed problem. Seen at least 3 Bottles in our fleet with this concern. (Can Not Blow any Air into Bottle). Just thought I'd pass it along.
Any chance this thermostat issue could cause transmission overheating? Possibly due to coolant not flowing right to the transmission oil cooler. Dealing with transmission overheating issue after an interstate run/sustained interstate speed, but engine is not overheating.
My truck never seemed to actually overheat but the cooling fan has not acted the same since the cam phaser replacement. Ran on high for a day or two constantly and now it’s just when I’m slowing down from highway speeds it will kick on for a few seconds and then shut off once I’ve come to a complete stop. Annoying as all get out when a repair causes something else.
I’m guessing you’re already using a cooling sys vacuum to fill the system. If not you should. It may or may not have solved this problem but it’s a great tool to remove all air pockets from the cooling system.
So I mentioned in the video where I was using and I did mention that I'm using the vacuum cooling system filler and that will not save this issue from happening I've already explained this and there's many people in the comment section here that it was explained it has happened to them as well it is a common thing when doing this
I just completed the cam phasers and timing chain/ all timing components after my water pump went out. Figured it was one cover away and I’ve had the start up rattle a while. After completion the Truck runs great but it’s overheating at highway speeds and idle after a long run. Thought it was an air pocket and had it vacuum filled today. Drove 30 miles and degas bottle dropped an inch. I installed a brand new water pump and thermostat and housing. Housing had corrosion on parts where the hoses slide over so I ordered a new one that was smooth and wouldn’t leak. The housing came with a thermostat I never even took it apart to look at it. Possible the thermostat is faulty? All parts were ordered from ford. Temps getting to 240 at times in this heat. Also I think the active air damn may be damaged investigating that tomarrow. Gonna prop it open. Thanks for any help.
Hello boss. About to take the truck into Ford to get the phasers replaced. Just skeptical based on the feedback with future issues such as thermostat over heating etc. Anything in 2022 come out to dial this procedure in? Would Ford replace thermostat and water pump during phaser replacement process? Would love to pick your brain. Appreciate it.
I am in a bind as one of thise inlet hoses crack and broke on the plastic Y as my wife was going to work it started saying coolant overheat and she was close enough that she turned around. I replaced the house and add coolant but the overheat message still there and car feels shaky and won't go past 3k rpm or drive fast. Like it is auto throttling itself for safety. I did the funnel to burp it but I think coolant not reaching the thermostat or it went bad.
Good info as usual. Let me ask an expert here. TPMS need help about flashing them and all that, all new to me lol. So if ya got snows and summer tires on their own rims and TMPS in them do they have to get flashed each change over? Please help very confused. Live in middle of now where so I change over tires myself, cant be running to shops for flashes they say. Please shed some light, I cant be the only one. Tks
I believe so, since the ECM can only learn 1 sensor ID for each wheel at the same time, it's pretty easy to do if u have the right tool, i used the Autel that is around $200, but if u know a shop and are a good customer they might not even charge u to do it since it takes like 5 minutes
@@denisgonzalezblandon1538 turn key to on, press hazard button 6 times. It’ll say “learn front left tire” on dash or similar. Can’t remember exact wording. Take a flat head screw driver and let air out of that tire until you hear a beep from horn. Then you’ll move onto the front right tire and so on. When it learns each tire it’ll beep. After all 4 it’s learned.
This problem is the exact issue I am having with my 2018 F150 King Ranch 3.5. My fans stay on constantly and when I run 75 plus and going up hills it wants to overheat. If I pull a trailer that is not loaded then it will overheat. In saying all of this I read about the updated Thermostat. I purchased the HLZ-8575 B. It actually says BA on the end. I replaced it and it fixed the overheating problem, but I had no heat. I live in the south and this was in the middle of the winter and there was no heat. We replaced it back with the metal one and I had heat again and the problem came back again with the truck overheating. Any recommendations.
Question? does this occur on all 3.5L ecoboost or is this isolated? I have a 2019 Raptor and because of the artificial noise they pump into the cab I can't tell if it is rattling. Only has about 24k miles on it and I live in PA.
Quick question for the Boss. Just had the phaser repair done to my 18 F-150. I noticed the cooling fans seem to be running all the time. I am taking it back to the dealer next week. I am curious if you might have an idea what it could be, or seen this after the phaser repair? Thank your for all your videos!
Thank you. I did notice in service the write up they replaced the water pump and seals, since after pressure testing the system the pump was leaking from the weep hole. Thank you again sir!!
I have a 2017 3.5 Ecoboost f150 with 75000 miles and if I'm in the turbo boost for a while either towing or not but more so towing the temp will start to climb do you think that could be the thermostat and also is there a way to find out if the cam phasers have been replaced I just bought the truck in may
