Today i had that bubbling issue for the first time ever. Tried taking my 97 camry to the mountains and we got about halfway up the parkway, when i started hearing a chuggong sound different from normal. Now i get i was going uphill into the mountains but still enough to say ok maybe this is too much lets pull off at the picnic area. Turned off the car in concern of overheating, thats when i heard the bubbles and saw it in the overflow tank. So i was like ok lets let her cool down so my son and I walked around to let it cool off. Checked the fluids beyond the radiator cause of the heat still and decided to head back down the mountain. We took it easy coming back (3hrs) but i think i may have killed the thermostat. Had the fans running the whole time and had the heat on full to displace some of the heat. Hoping there is no bad damage.😅🙏
Great video. I have noticed that if the radiator has no cap and just the tank to it's side , if you have to continue to fill it , ya got a bad head gasket . And if ya smell antifreeze coming from ya tail pipe , and the motor is running hot , ya got a bad head gasket.
This is a great video. You forgot to mention that if the car is not overheating and the coolant reservoir fluid is boiling that it could be that one of your radiator motor fans isn’t working. This was the case when I took my Honda in today. It has two radiator fans so you could hear cooling noise but when you looked at the second fans it’s still. My radiator lid was busted to and had to be replaced. I’m just pleased it wasn’t the head gasket 😊
I have a friend's vehicle that was making bubbling sounds after shutting off engine. Check engine light was on...read codes...#3 cylinder mis-firing....had a blown head gasket. Lady just bought the used vehicle 2 months ago. It pays to have someone check/inspect any used vehicle before buying. The lady got ripped off.😕 (Lady thought check engine light was always supposed to be "on")
I had an interesting time after replacing my radiator. Even when parked on a hill, it would pump the coolant right out the top of the radiator while the engine was running, and the coolant was boiling when it was running, but the temp gauge stayed where it should be, never overheated. Went through gallons of coolant until I realized I forgot to plug in my radiator fans. Problem solved, but still has me scratching my head
I've got an interesting cooling problem that has me a little stumped, my Honda civic just got a new OEM thermostat and radiator cap as well as a coolant flush and replace and it works perfectly fine 99% of the time. It had a lot of irregularities in the temperature before the work. Now it stays at the same temperature almost always but then will randomly spike in temperature for about 30 seconds to a minute then immediately cool down and go back to normal. Last time it happened coolant reservoir overflowed and spilled out. Fans and fan switch work fine and thermostat opens fine in boiling water. I did a hydrocarbon block test for a head gasket leak 3 times and it detected no combustion gases which made me happy. No white smoke or obvious leaks anywhere and no real coolant loss. No one I've talked to really knows what the problem is and I don't either, do you have any ideas? Thanks
Update for anyone who read this, turns out my condenser was pressed against my radiator from an old accident apparently which was adding heat to the system. The main problem though was the AC was only turning on the fans for short bursts of time instead of it being on constantly. This was leading to overheating spikes at low speeds or stops while the AC was on. Bypassing the fan switches and having it on all the time during city driving seems to have solved the problem completely. As well as moving the condenser away from the radiator.
@@isaacwollard2084 this is interesting ..I put a new ac condensor on my car (mine attached to rad which was also new) that alp seems fine but it's the ac fan running that's got my attention..I've got a new oem coolant sensor (I hadvreppaced but was aftermarket) wondering if it could be as simple as it being no good ..my fans (both) come on intermittent when ac is on which I find odd
just saw your response, and also have a 91 civic - just had a whole new a/c system installed, the next day she was a boiling teapot.. wondering if this could be the culprit - toooo coincidental
Hey can you make a video like Chrisfix with the with the bubbling noise on the moc... And how the temperature gauge look when it's overheating so we can actually hear and see how it sound and get some understanding on the noise and how the sound
I have a 2012 cruze that did that...Found a trick that actually worked......After I re-drained my coolant out and kept trying to bleed air out of the radiator and that didnt help........I found out all i had to do was UNHOOK the negative battery cable for a few minutes............Believe me it works...Anytime i had to open the system or a hose blew or something I had the bubbling boiling after shutting it off...Take off the battery cable and bam fixed...........It works on my Cruze..........
@@LUCCAWRLD It worked for me....Seemed about every time I had to open the cooling system the bubbling/boiling would happen as soon as I turned the car off.....But it only takes a couple minute to take the negative battery cable off for a couple minutes to see if it works for you..........
I’m looking at 2019 Toyota Tacoma. It appears to have this same set up. I recently purchased a Block Tester Kit to detect for exhaust in the cooling system. MY QUESTION: CAN I PLACE THE TOOL INTO THE COOLANT RESERVOIR TO CHECK FOR EXHAUST OR DOES IT HAVE TO BE PLACED DIRECTLY INTO THE RADIATOR CAP, after removing about 3 inches of coolant. Please help me with this! @BudgetMechanicHawaii

@@BudgetMechanicHawaii Yeah sad story...she's decided to drive it til it squats. She's 84 yrs old...vehicle has a 5 speed manual transmission...ha ha...that's interesting. 👍
I only hear the bubbling sound when I turn on the AC on my car than it goes away, it’s a 2017 Honda accord touring, just had the ac fixed about 5-6 months ago, I haven’t seen any over heating, although I did add coolant about 1-2 months after it was fixed and went a bit over the full mark. Haven’t seen any sign of leaking, car did have the coolant smell after it was fixed for about 2 months than it went away. I have no money so I am trying to hopefully fix it myself if it’s simple enough. What do you suggest?
Your coolant degas bottle has 2 little holes next to each other. Mine has only one but the new one came with 2. One goes to the radiator. Where does your other one go and can I just tee them together since mine has only one
My replace my radiator for the old one was leaking, and now my fan works only when I turn my AC On, did double checked all the electrical connections were look good I can’t figure it out what would be my problem
There's a radiator fan switch usually on your thermostat housing which senses the coolant temperature and turns on the fan when it gets hot, could be a bad fan switch or a bad relay or fuse going to the switch. The fan switch went bad on my car and I could only turn on the fans with my AC button, replacing that fan switch and that fixed it
Hello I have a weird coolant issue in my 09 Audi s5 4.2 b8. Whenever car gets warm and up to temp after driving a bit, my coolant reservoir drips from the bottom of the reservoir. Stops after car cools down it seems but could replacing the reservoir fix this issue? Car doesn’t seem to be overheating to my knowledge either with this issue
I hear a crackling sound in my 2020 sienna. Immediately after the coolant temperature too high pops up then a minute later goes back to normal. Please help
I have a Nissan Primera p12, got it back a week ago from a paint job, check light came on , when engine off hearing a humming sound, days ago now it's switching off while I am driving
Hey I have a Lincoln LS 2002 V8 3.9 and I have a coolant reservoir tank but like you said you can't determine how full the radiator is with that so how do I check to see how full my car is with radiator coolant right there where the housing is where the thermostat is there's a little thing on top do I unscrew it to check and see how much coolant I have
I have a interesting problem. 2016 Altima over heats sometimes blows water out the overflow. Overheated on a trip added water drove 200 miles home no problem then over heated in drive thru next day. 2 new thermostats, 3 different pressure radiator cap and new resivour cap still blowing water to point hoses collapse. passed pressure test on system and test for head gasket. Havent caught fans not working. 2 mechanics is confussed by it.
Does the coolant level go down at all (other than the blowing out the reservoir)? Does the vehicle behave for a while after refilling coolant? Slow coolant leaks can be annoying to find, but once the level decreases to a certain point, the engine boils the remaining coolant and blows it out.
@@BudgetMechanicHawaii Only place i seen it come out is the overflow. There is no other leak to be found besides that. But you do have to add coolant back to it.
It was acting ok oneday i decided to add some water to it. Within 10 miles it overheated after that. We limped almost all the way home and it quit out of blue.
same thing happens to my Altime 2008. I’m driving it for 100KM and on the way back it gets heated and boils the coolant and empties the water in Radiator pump. I had to fill water again and again
@@BudgetMechanicHawaii If it cool and start car after refil will drop then once topped off no bubbling or nothing. Turned out being radiator halfway clogged up. Letting some water thru but eventually over heating if run a while
Hey I have a bmw and I change my water pump new hose for my radiator and new coolant and my car don't overheat the temperature show good but my coolant boil and gets hot but the temperature say it's good I need help
Hey can I recycle the coolant out of my coolant reservoir for my 2000 honda accord? My coolant reservoir is way pass the full line, and idk why but I don’t think the system is working properly because the pressure isn’t sending the coolant out the reservoir back into the radiator… but then again idk if it’s even supposed to do that…
It is supposed to do that but only if the radiator needs fluid and only in very small amounts. Yes you can recycle fluid but I would strain it thru a rag or something to get out any debris
Hello, thanks for the video. I have a question. Can you use g12+ coolant in Japanese cars (I live in central Europe, and we use g11-g13+ as a standard). The interesting thing is I have a suzuki sx4 and the manual recommends the suzuki coolant (a phosphate HOAT OR similar ethylene glycol-based one), BUT this car was also manufactured as a Fiat Sedici model too. Its manual just refrains from silicated coolant use and recommends Fiat's coolant😂 Some people say filling the wrong coolant is bad for the engine-water pump... but there are two things: in Hungary most coolant bottles state (suitable for every passenger car -alloy friendly-or cooling systems) plus I have filled my previous suzuki with the same G12+ coolant of the same brand. it didn't freeze or lose coolant even in hours of highway driving during really hot summer time 🤷🏻♂️ what do you think? thanks for reading :) 👋🏻
It will take any coolant it's a Japanese made but the alloy one sounds good if cheaper .. it just dose not like water as it rusts the hose ports they used but I have ran one with water in the cooling system for months with out any issues but can see years later when replacing coolant lines surface rust on the connections but easily removed with a brush but coolant i would put anything cheaper in it with out any issues
So when your coolant makes bubbles after turning of your car it's never a 'normal' thing? I have my car checked but they couldn't find a thing. No other symptoms related to a blown head gasket either. Don't know if I should be worried or not.
@@SmDWeed that i'm not really sure either, i'm having this problem and my car just got back from the shop for head gasket replacement and had the head resurfaced. but it point to air introduced into the cooling system, often exhaust/combustion gas, which means head gasket failure or cracked cylinder head/block
@@BudgetMechanicHawaii I replaced the cap but I made a mistake and put straight concentrate coolant in and now it overheat but the fan kicks on at 226 degree and the temperature goes down
When i start my car with cold engine eith radiator cap open air bubbles keep coming out and when i slightly race the cold engine the coolant jumps out of radiator filling hole. Please anyone tells me what wrong with my car. There is no coolant lose and it keeps stable. Also i noticed very thin layer of oil on coolant surface in reservior bottle. No moisture observed in engine oil. Please somebody help me. My car is honda civic 2005 with D15 engine. Thanks
Does coolant surge out immediately on startup? Even when cold? If so that sounds like a head gasket leak If not, when air and coolant heat up they expand and will overflow if the rad cap is off. But that’s normal
It will overflow onto the roadway via a tube made for that express purpose the next time your radiator system heats up and sends more fluid to the reservoir.
Hello my car overheats only when I’m in a drive thru line then goes back down to normal after driving away. What could be the cause? My engine coolant is all the way full as well
I had thermostat replaced on a 2007 Chrysler 300 c and mine is bubbling over heating.can u please suggest anything so I want have to keep spending money on the same thing thanks
I was having same issue with my 2015 dodge dart... I was loosing coolant and tried to overheat like in the 3 quarters temperature and turn out to be the reservoir cap being broken from the top of the inside seal... I bought a new cap and no more overheating but I think I overfill it the next day because I saw coolant on the hoses but the reservoir tank its at the full level.. why did it leak or throw the overfill coolant thru the hoses or hose?
I have a dodge journey 2014 and I just had a over heat blown eng a few weeks ago took to shop had it fix it was running fine now I have the bubbling and boiling from the resivoir It is over heating but only to 255° don't see any leaks and my lvls are good. Out of the info you explained what do you think it is?
@@brettjolliff ok Brett, but it's not because any significant "U" or "S" shaped bend in the hoses or maybe the radiator (which is full of them) could theoretically not allow the simple elevation of one end of the vehicle to fully purge the system of all of the trapped air. Also known as an "air trap". At least that's what my common sense told me, but if the guy says it worked for him then great.
My car doesn’t over heat it stays normal . But when it gets hot the coolant boils and over flows . This is with the cap off.. if the cap is on then the pressure pushes it out the crack in my radiator.. what is causing this to over flow my coolant tank? I did a block test and the liquid stayed blue and I have no white smoke so idk about head gasket
But mine stays around 210 but boils over, I replaced the thermostat hoping thats what it was bc it was getting hot. Tried to burp it afterwards and it just boils over my reservoir tank. I dont have a radiator cap just the white pressurized reservoir. Do i just let it boil over until all the air is gone. i feel like its never going to stop, so I shut it down. But its telling me the motor isnt hot. But that fluid definitely is hot coming out and so is the top hose.
I have a Vauxhall Astra 1.6 2010. Symptoms are a sludgy mixture in the coolant however when I take oil cap off it’s clear and dipstick is clear. I had a warning light saying engine is overheating so A/C is turned off but that only stay for a 2 days while the thermostat dial was not working. It starting to work after and the thermostat has never shown a dial reading of overheating. I have been told it is a blown gasket. However someone else has told me it needs replacing of oil coolant and Flushing out radiator and reservoir tank. Any advice please?
I would flush coolant system to see if you can clean that out. Sludge will also disrupt the thermostat so replace that after flushing. Hopefully that’s all you need.
My car is overheating and near the reservoir and radiator I heard like thumping and it was moving.. kinda feel like it’s time to trash the shit box need some guidance on how to fix, was thinking about changing everything
Shops sell anti freeze but coolant has a higher boiling point. Bottles offer little information so many miss it. Honda Type 2 Coolant for example has Boiling point: 131.1C Freezing point: -36.6C according to an importer. Fluids also have a higher boiling point under pressure. So you may run into trouble with just anti-freeze and a leaking cap. I also like to mention that temperature gauges are mounted at a low point in the cooling system and therefore more an indicator for having reached the normal operating temperature. Boiling hot water will stay on top and when the high temperature gets registered the fan switch will activate the fan. Use coolant with metal protectors that are no silicates, Like Honda Type 2. Wearing the seals, waterpump and thermostat, mainly by silicate is, indirectly, a cause of overheating. Always look down into the opening when safely filling, with a small light, to see if the thermostat is closed and in one piece. The metal alloy can dissolve and fall apart. The temperature gauge on the instrument panel can tell if the thermostat opens at operating temperature.
I have a 99 accord v6 ex during summer time when it’s up in 90s to 100 out side with car ideling in like a parking lot with ac on temp gadget goes to hot a few time always full of coolant would it just be the hot weather outside causing this problem other wise when weathers cooler it’s fine no heating up.
I replaced the radiator in my 2013 Silverado. Ever since it won’t hit opening temp unless it’s parked. I’ve been driving around for a few days now with the res cap almost off. Hopefully the bubbling sounds go away
While cool crank take top and squeeze the mane hose a few times antifreeze goes down fill back up to top and squeeze again few times till antifreeze comes to top then all the air will be out of it put top back on a drive
What happens if I have too much coolant in my overflow tank? I have been having a periodic overheating issue for over a year now, and I have been surviving the issue by adding more coolant to the radiator before long drives. I clearly am losing coolant, but have not been able to discern from where yet (I suspect a bad thermostat may be playing a part in all this). During this time there has always been a lot of extra coolant in the overflow tank, but it never seems to be drawn back into the radiator. Is this due to it being overfilled...? What are your thoughts? My car is a 2002 Subaru Outback with about 286,000 miles if that makes any difference.
@@jannat8114 I have tried that with no success. I also replaced the thermostat and radiator but am still having issues. I’m coming to terms with the fact it is probably the head gasket unfortunately.
My car makes a bubbling sound when I first rev it and when I accelerate when driving but only for the first 2 or 3 times and after that it stops..and my coolent needs to be topped up every few days..anyone got any ideas
You may have a clogged and leaky heater core. Check for moisture on the passenger side floorboard, under the mat. You may also smell the sweet odor of antifreeze at that time or , eventually, notice that a greasy haze has developed on the inside of your windows. That is antifreeze. Definitely read up on the heater core-- the miniature radiator that sits inside your cabin but circulates the same coolant as the rest of the system.
Hello i have a 2008 mazda bt 50 disel i had a engine rebuild because it had a bad head gasket and it was overheating i pressure tested the block and head as well as had them decked. They are all good had the radiator cleaned and its all put together now and on inital start i have the rad cap open and it seems no pressure is building or bubbles but after it warms up after it reaches operating temp i open the overflow tank and see little bubbles coming out of the hose in the overflow tank . It does not loose any coolant even after driving for 30 minutes and when i open the cap when its cold it seems to not loose coolant and engine does not run hot. I am runnig without a thermostat can that be the cause? Or what am i missing
The only way stuff gets into overflow is thru the radiator cap. Wouldn’t hurt to replace that but if you’re not losing coolant I wouldn’t worry about it
