I was a mechanic for many years until My career ended due to life-altering issues. I just wanted to let you know, that your videos bring me joy and comfort! Thank you!!
First step: Remove fuel pump fuse, crank starter for a few seconds to remove fuel and pressure from fuel line in order to release the grips on the line. Second step, have engine engineers put in jail for stupidity for putting the sensor in a position that required the removal of 1/3rd of the engine to access sensor.
After putting the engineer in jail, give the manager and accountant a bonus for the 3 cents per unit cost savings by making the engineer put the sensor in the worst location possible.
If they are still using the popit type fuel injection, turning the engine over with the fuse out won't release the pressure.. they'll still be around 50 psi or so.
I did it with a deep well socket, 3 in long extension, universal joint, and ratchet. All half inch drive. A 6-in extension is too long but a 3 in extension and universal is just right. The ratchet handle will swing over top of everything but the ratchet will still fit under the bump out of the firewall. The only thing I removed other than the sending unit is the plastic cover on top of the engine. Fuel rails stayed in place.
Ray, you made my life very easy with this video. Had a 5.3l Chevrolet Savanna come into the shop, probably the only one in Europe. We had already replaced the transfer case and did the TSB fill procedure. Then I noticed the oil pressure gauge doing the same as in this video. Fortunately I was able to pull the rear engine cover inside the car to get at the sensor since US car parts in Europe are scarce (took six months to get the transfer case from the US). We made a special socket and got the sensor swapped out without any issues. Pressure gauge now reads as it should. Thank you for this video as it made it a very easy job seeing where it is and what’s needed.
Couple years back when I was in my teens, my dad replaced the sending unit on a Tahoe but told the customer to order OEM parts and they bought the cheapest one off ebay and insisted on it being installed, needless to say they eventually listened when the issue came back and he told them this would happen lol it was not even two months and it broke again, put a OEM part and it's still working now
Just letting you know I enjoyed the video Ray. I do hope that if the hurricane arrives that first and foremost no one was injured, and secondly that property damage was minimal. I grew up in the tropics of Australia and went through more than a few cyclones. I understand what you guys go through in hurricane season. Stay safe!
I am only a few minutes in, and I have got to say that the Suburban you are working on appears to be exceptionally well cared for. The 1999-2007 full size GM chassis trucks are really hard to beat. BEST of luck and safety to you and your family with the possible approaching storms.
Yes indeed , I have a 02 Tahoe. With 275k miles since new. I have put some money into it. Like a head gasket, replaced exhaust valves while there. It didn’t have the defective castech heads that GM encountered in these years. Thankfully… rebuilt trans with corvette servos…And normal wear and tear parts etc etc Since then i can’t break this truck. Just do faithful maintenance.
They are tanks! About 7 years ago I was hit by a drunk driver who was in an early 2000 suburban. She went the two traffic lights and the traffic control box before slamming into my rear fender. Needless to say everything bent to will of the suburban and it didn’t have a scratch on it other than a small dent in its chrome bumper. My Nissan Sentra on the other hand did not fair too well.
@@chronovore7234 I had a Nissan Xterra rear end me and totaled their SUV I suffered a dented tailgate repair and bumper replacement. I even tried to move away from the collision in the lane next to me anticipating his collision. He still found me. 😂 anti lock brakes I guess locked anyway in the rain.
The servos in early 2000's Chevys are known to go bad. My 05 Silverado had bad servos. Nice thing is that there are cheap after market servos available that are really easy to replace without having to replace the whole cluster. Changing mine start to finish took about an hour. Side note: I do have a great picture of a police car in front of me and a red light in front of him with my speedometer pegged. Even though we were stopped, the pegged speedometer in the photo made it look like me and the cop blew the light doing 120mph.
I've removed those senders with a standard 1 1/16 before, but you have to be VERY careful and have a perfect straight shot. (Too cheap to buy the socket since I don't do it for a living).
Ray the thing that I like about you is your awesome sense of humor. Also your are one of the most meticulous mechanics. This makes you very enjoyable to watch. ❤🔥
After you do a few of those senders with the intake on and get the hand motions down they're really not that bad. Stubby ratchet and wobble extension. Just removing the fuel lines makes it much easier too.
Until the water starts coming into your house. Two inches is all it takes to have a totaled house. You have to gut it then. Worse is two feet - cause you watch all your stuff float off and it leaves two inches of mud in its place. Been there done that.
I thought he was going to run around saying the sky is falling the sky is falling the sky is falling but he just manned up and kept on going have a great day
@@michaelpressman7203 nah most people who grew up in florida arent worried about them. general rule of thumb is be worried about a cat 3, get the hell out of the way for a cat 4 or 5. 1 and 2 are just a rainy day. trees down in Florida mean nothing because roots only to down like 3 or 4 feet even if the tree is 100 feet tall the water table just isnt that far down
I had to replace the sending unit on my 05 Sierra a while back and managed to do it with just the over off. Mind you it was a total pain and I planned to do it before driving so no heat to deal with.
Seeing those towels in the intakes brought back a situation I saw in my youth. A friend had a 58 Chevy with a 348, it broke the distributor drive and when he pulled the intake so he could get the broken piece out he stfeed shop rags like that. To make it short he was in the drives seat and wanted the radio on and turned the key to far. A week later with new head gaskets and distributor on it lived again.
I have had a replacement sender for my 02 for several years. It has a fluttery reading at idle but reads fine under power. A common problem. Looking at this vid ... and procrastination has served me well on this one... what a pita for something so simple.
The oil pressure gauge on my 2004 GMC Sierra 1500 5.3L with 200k+ miles has been pegged above 80 psi for, I don't know, probably 6 or 7 years now. It has no relationship to the actual oil pressure, fortunately, but also no relationship to the sending unit--just a stepper motor issue. It also never throws any codes.
“The best part of waking up, is Folgers in your cup.” That was so 80’s Mr. Ray. That was when Folgers used to sell coffee bricks (coffee bags with all the atmosphere sucked out for guaranteed freshness). Those were the days!!!! Oh btw; thanks for the throwback Sir.
I had that same symptom on my 83 mustang years ago. Turns out that the oil pressure sending unit got sheared off from a frayed serpentine belt. New belt and sensor, back to normal.
I had a 2003 avalanche same issue and my friend a mechanic replaced it within 15 min. Like you, he knew where it was and tools to remove. Just realized you Ray, love taking things apart. Lol, and awesome at it! Great video as well. I too am impacted with theses hurricanes. Stay safe and to all us Floridians. Have a great day!
Chevrolet has the worst presser sending units ever. Had to do the one in my wife's 2010 Impala this spring. 10 minute job. I would be heading north west..this could get ugly. You get to my age and just waking up makes it a good day.
Back in the 70’s and probably later, GM used to mount the oil sending switch on the front of the engine. It was literally a 2 minute job to replace it.
Helps to release as much line pressure as possible. They clip on, but are held on firmly by the pressure behind them. That's why they use them for fuel lines, the more pressure they are under, the more secure they are.
Considering the age of the vehicle, I would have done the same as Ray and pulled the intake and check connectors and wiring also. I have been bitten several times on older vehicles where the wiring or connectors have became brittle and had issues. Great job Ray!
Same, my plow trucks come to mind, thats a handful of 6.0 gassers with a variety of electrical issues I need to be very careful about when making repairs.
Not as difficult as you would think. Most everything will lay back in plqce where it goes and electrical connections will only plug into it's mating connector.
I put an alternator in my car last week and I dropped my 12 mm socket hunted for it with a flashlight and a magnet could not find it drove the car was running great but and two days later I said I got to find that socket I opened the hood look down and there it was sitting at the bottom of the engine cover that protective thing under my motor that does I don't know what and hey I must live right cuz I got my socket back and I hate breaking up sets have a good day
Just did my knock sensors in my 02 silvarodo seen you also did the rtv around the boots like the service bulletin called for back in the day...2nd round did it myself since it wasn't done right the first repair although they did last almost 10 yrs without the rtv. Anyways keep up the great content and you helped me get motivated to do more repairs myself
Great video as always Ray!! Fingers crossed you don't get too much from the storm; current models have it mostly hugging the west coast heading up to the panhandle, but having lived in Houston a long time I've seen how those things can change direction and get stronger. One of the reasons I'm fine with living up north even if the salt makes fixing cars more of a hassle.
Had the same issue on a 2003 Trailblazer, but the oil pressure issue was the little stepper motors on the dash. Replaced that and everything was good. Stay safe in the hurricane. Great video as always.
Had an 04 Yukon XL, half the stepper motors went out. Speedometer would still go up when slowing down until it pegged out. Replaced all and everything was good. It is a common problem in those model years. So much so that GM warranties them up to 70K miles if I remember right.
I love the whole knock sensor job, with the RTV Dam TSB... lol what a fix. Been there done that 10yrs ago.. bought all new connectors and oem sensors and the metal gaskets. Packed full of mud under there... and really fun when they break off and you have to pull the lifter galley cover and use extractors to fight that...
Working in the equipment service industry, one of the first things suggested was to remove the watch and ring. I saw someone burn their watch band off when they reached behind an alternator, not a pleasant outcome. Great content, like the commentary.😎👍
Met a fellow who should have known better but managed to get between a ni-cad battery on a helicopter with his wrist watch. No pretty and the watch wasn't working too well either.
Way back in the dim dawn of time, I had a customer with a 65 Ford with a 289. His oil pressure relief valve stuck closed. You could rev the engine up and watch the oil filter bulge outward. I was surprised that it didn't blow up the filter or gasket.
That's convenient. I own an older 5.3, and I replaced the oil sending unit last year. I never got to remove the intake, so your video helps, especially the way you identify parts as you go in. It sounds like later models are harder to reach. Along the way, I found the sending unit is a simple resistor, so you can mimic it with a simple resistor led to ground. In the dealers manual they tell you what the gauge should read with, for example, a 100 ohm resistor fed to ground.
Proper way to diagnose if your oil pressure sending unit is bad is to check the grille for a Chevy or GMC badge. If it has one and the gauge is at 80, it's the sending unit.
I installed a new sensor when I changed out my Knox sensors. It blew out on the highway two weeks later. Literally the oil was blowing out the top where the connector was and lost all the oil. Had it towed in and changed it. A week later it stopped working. Those two were from Oriely’s. Bought one from Auto Zone. No more problems since. That happened last year. A similar situation happen with my jeep Wrangler. Bought two from Oriely’s and went out right a way back to back. Bought a new one from AZ. Still working three years later.
These cars you work on drive my OCD crazy. They all have a ton of leaves stuck below the windshield, wipers and along the fenders. It's fall here in Virginia and I'm constantly de-leading all my cars.
Ray.. in regards to your coffee comment. Years back a friend of mine told me this quote because I drive a diesel.. "Who needs coffee when you got torque?"
Hope all is well Ray I'm in the UK very rough looking storm watching the news about sunny florida work must be cancelled for a while surely all the best Ray from us here
When I was doing that stuff, I had a movable floor fan, aiming it just over the engine so it would pull cooler air up and around the engine. Worked faster than I thought it would.
Haven’t even watched the video, already know it’s a bad oil pressure sensor on the engine, I’ve replaced a bunch of those, they seem very common to fail on those trucks
Good morning Ray, thanks for the video. It went smooth as butter. I'll be busy getting ready for the hurricane 🌀 today. I don't have a generator so if the power goes out it will be bad 😞. Stay safe and have a good day 🇺🇸💪💯
I myself Wired my house for generator so I can plug it in the side of the house and back feed into the service main disconnect thing if you do that disconnect your breaker box on your meter if you don't backfeed the power lines and electrocute the workers have a great day
@@michaelpressman7203 I have a suicide cable to connect my generator. Procedure is the same as you said. Shut off the main breaker, plug in both ends of the cable, start the generator. My setup has a breaker in the box just for the generator and the generator has it's own breaker. Double protection. Disclaimer: Don't do this. CYA and all of that stuff.
Just wanted to put a comment here. I did one of these sensors on my 05 suburban and I did it without removing the upper intake. It took like 15 minutes and the job was done. I understand why mechanics in shops would do this, because the book more than likely says to remove intake, but with the right socket and extensions it can be done. I am simply sharing my own experience, no hate towards Rainman.
My wife was coming back from New Orleans to Arkansas when she got to Jackson MS the oil sending unit cracked evacuating the oil. She check the oil and refilled but too late. She trashed an overhead cam bearing. I drove to Jackson and put the car on a dolly returning it to my Mazda dealer. They installed a new head $5100 then found a knocking crank bearing. I bought a a 10,000 mile pullout engine and installed. All over a plastic cracked oil sending unit.
I replaced the oil pump on my ’05 Silverado. 250K miles. It was clattering at idle and less than 20PSI when running. New oil pump came with 2 springs, regular and high performance. I put the high-performance spring in, had 100PSI+ oil pressure. Bad ideal, blew apart the oil pressure sender. Yea I got to do the oil pump twice with right spring and replace oil pressure sender. Was able to replace the sender w/o taking off the intake. Had the right socket, but man it was a lot of contorting, almost worth it.
Ians building up for a ( depending on where you are in Florida ) cat-1 on up to cat-3 and 4 possibly. My sister in the northern parts is expecting at most a cat-1 with 10" of the sideways liquid variety. Hope you fair well, both at work and at the home. Best of luck and health Ray.
I've seen you pull the intakes doing the sensor on the GMT900 platform, they do look tighter, and it may actually be necessary, but from doing them on a few of the GMT800s I've owned I can say with 100% confidence that pulling the intake is definitely the hard way. The last one I did on my truck took maybe 15 mintues and I didn't have remove or disconnect anything, I didn't even remove the engine cover. I've never used the special socket, mainly because I don't have one 😅, but a regular deep 6 point will work, I believe it was a 1¼ that fits, it may look like there's a bunch of stuff in the way, but with a 6" extension it was a straight shot, cleared the harness, fuel lines etc.., the old one will come right out without problem, the hardest part is starting the new one back in blind, but even with my fat hands/arms and a warm engine its not bad.
It’s hard to make a 30 minute video when you do it your way. What’s he going to do for the rest of the time? Lol Edit: These videos are, in a way, educational because they show you how to do these specific jobs. If we can’t see what he’s doing, then it wouldn’t be a very good video.
I did the sending unit as a old man a few months ago on a yukon and with a bad back it was a nightmare to leave the intake on lol a younger me may have saved time but old me could have done it twice by taking the intake off lol
Always Rainman Ray's Repairs Water and Coffee each morning. Thank you. Damn Knox sensors and Oil Pressure sensor! This home Mechanic has tackled this one. What I found is the three failed somewhat together because when it gets hot, coolant sprayed all over the back of the engine from those damn plastic (not so) quick disconnects for the heater hoses to the firewall for the heater core. About the same mileage as this Suburban.
Using the scan tool, can you activate the water pump and cooling fans? If so u could do that to cool the engine down after without turning the car on. (I'm guessing the water pump is mechanical though)
I call REEEE on the internet connection to your flashlight. The flashlight dimming up and down and flashing is just to remind you that Halloween 🎃 is coming up soon. Spooky 👻 flashlight!
