LS / MKZ :: Overheating - Low Coolant
Jul 7, 2015
I was having an overheating issue. First thing to check...does it have coolant. Reservoir said yes. Changed thermostat twice. Still overheating. Changed Water Pump & Belt. Still overheating. Decided radiator must be plugged so bought system flush. Opened radiator, about a quart of coolant came out. (BTW even after draining there was coolant reading in the reservoir). Filled everything up, followed the bleeding procedure and no more overheating. I'm not sure how the coolant reservoir works on this vehicle but I don't trust the "cold full" reading anymore.

I have a small car which has only done 28000 kms and I bought it brand new. I have noticed it has been using more coolant than normal and it has become quite hot at one point. My mechanic went to service it and said it appeared that water was in the engine. (contamination of oil underneath the oil cap). As it is under new car warranty I took it back to the dealership. They said it was due to leaking core plugs and have replaced them. My mechanic said if it was leaking core plugs the coolant would be leaking out onto the ground not into the engine and contaminating the oil. Dealership said this is rubbish. I am confused and don't know who to believe. How do I know if it has been fixed or not and how do I know if it isn't something worse like a cracked head gasket?

Had a lot of problems with my Rover streetwise's heaters / overheating engine. Firstly, the heaters were rubbish & took ages to heat up. I took to garage and they pressure washed the coolant system to clear any blockages. This didnt work so they changed the thermostat - this has worked the time it takes to heat up but now when i use the car for the first trip of the day, t as soon as the engine has heated up & the speed hits 50/60 mph, the temp gauge shoots right up to the red zone - so have to reduce speed. The 2nd trip of the day, it seems to be fine - its literally just on first use of the day ie to work.
All oil & coolant looks fine and the head gasket was replaced summer last year.

So I noticed one day when I was standing outside of my car right after I had turned it off that I could hear the coolant bubbling some. I had just recently flushed the coolant, put on a new water pump, thermostat, and put in a new reservoir with a new cap so I figured it was just some air in the system because there was air in the top radiator hose. So I just worked the air out and thought that was it. The next time I drove my car it did it again and there was no pressure release when I took off the cap either. I ended up getting the head worked on (valve job and check the head for warping). Even after all of this my reservoir doesn't seem to build pressure and every time there also seems to be air in the top radiator hose. After the car is warm I can work coolant back in the hose and 5 minutes later theres air back in it. I've pretty much replaced everything with the cooling system besides the hoses within the last year so I don't know what it could possibly be.

I have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.
Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.

My son has a 94 Escort LX and this weekend he noticed that when he'd stop the car he could hear the coolant boiling. The car temp gauge never registered too hot, and it never lost coolant. We checked the oil and it is not milky.
About 2 years ago it got a new water pump. Last summer a new thermostat, and then earlier this year a new radiator.
Last weekend he was stuck in a huge traffic jam. (4.5 hours for a normally 45 min. drive). I'm wondering if that could have weakened the radiator cap. He's picking up a new one today, but wonder if there is something else we should check?

Today I received a message on the MFI telling me that the coolant was overheating. My better judgement told me to immediately pull over at the next available spot to turn off the car since the coolant temp gauge was almost at 280. This is well over the 200 where it usually resides. However, the oil temp gauge was right at 200 which is normal.
Perplexed, I called my dealer. The Phaeton Tech was gone for the day so they suggested that I have the car towed in for inspection. Knowing the temperament of the Phaeton (2004 V8), I chose to restart after about 5 minutes. At that point, everything was reading fine & I drove home (about 20 minutes). I ran a VAG-COM scan to see if anything would come up, but nothing did.

On a few occasion, usually during cool weather, the engine temperature rises up to 130 C, the coolant overheating warning comes on for a few about a minute or two and then the temperature goes back to normal (90 C.)
The car has 106,000 km. I purchased it last summer from an independent use car dealer. I inquired about the car calling the previous owner. He did mentioned that the only problem he ever experience was that the car overheated on a few occasion during the winter months (cooler weather).
Could it be that the thermostat needs to be replaced?

Mk4 Jetta Gli 1.8t , car was over heating only when sitting 5+ minutes at idle, mechanic said the big fan needed replaced so he replaced it. Car still over heated so i replaced the coolant with G13. It hasn't over heated yet but got in the car this morning and the coolant light started flashing and car was telling me to STOP the car. Checked out the coolant and it was on the low side. What it may be? Leak somewhere? Bad thermostat or water pump gone bad? Timing belt and water pump were done when i bought the car when it had less than 50k miles, car now has 99k miles on it.

So i have a 01 LS and i love it so much. Ive only had it for 5months and since the 3rd month ive been having some overheating problems. Ive replaced the coolant reservoir it drove fine for about 3weeks then started to run hot again and leak coolant out the reservoir cap so i replaced that. Still ran hot.. so my brother got some air pockets out of the system but, it still ran hot. So i replaced the t-stat. After replacing that it did fine for a few days then started to run hot again. This time it seem to run hot one day and not the next until one day it ran hot constantly and steam would come from the reservoir and coolant would leak from under the car (behind front drivers side wheel.).
So when it leak i would check the overflow tank sometimes it will be full and sometimes not. When it wasn't full I would refill it until i ran ran out of antifreeze. Well i parked it after it leaked out the last of antifreeze that was in tank. So a few days later i got some antifreeze that was given to me by my brother which was red/orange all purpose antifreeze. I filled the tank up as it was dry and had leaked out all the green antifreeze. I started the car and let it run. It ran for about 20min without getting hot quickly like it usually do, air worked great but hea not so great.
Then I started seeing steam come from reservoir tank which was full of red coolant then its started leaking GREEN coolant instead of the red i filled the tank up with. Also the temp gauge never went to H while it did all of this. And the antifreeze drip from like 4 or 5 different places behind my left front wheel. Its a v8 3.9 engine.
I know one day i checked my coolant after it ran hot one day and it was low so i filled it up with water and forgot to put cap back on and i hopped on freeway. Soon as i got off it started smoking really bad i pull over and the coolant was boiling which i also forgot to mention. Thats another thing it has been doing. But the smoke came from the coolant boiling in tank and since i forgot to put cap on the smoke came out freely from tank. Could this have caused a problem. Although my car was running hot with coolant boiling in reservoir way before i did that and even after.

Ok I have a friend with this car and said it kept over heating. I went and looked at it and found the source of the leak. It's right after the heater core. The hose comes out and into the engine. Where the hose slides onto the engine has a leak . It looks like the piece can unscrew and be replaced but I don't know what it's called.

I noticed my 2002 Camry XLE was overheating and discovered that I had lost a lot of coolant. I topped off the radiator with pink 50/50 and went for a little drive, after parking I noticed a slow coolant drip that would eventually stop.
I took it into a shop, and they did a pressure test and found the leak was from SOMEWHERE behind the intake manifold. They also told me that it may be a "common" problem in my year that the threads in the cylinder block are pulling out, causing the cylinder head to lift and coolant to leak. They claim that they have to pull of the the valve cover gasket and inspect the torque for the headbolts, if they're loose I'd need to replace the engine block (!!!)
My thoughts are that it must be coming from somewhere near the intake manifold. I just had it replaced five months ago and am thinking something went wrong in the process.
I guess my questions are, is the bolt loosening thing legit? I'm not burning off coolant (have checked exhaust and it's clean, not white or anything). And what if anything could have gone wrong in replacing the intake manifold to cause said leak?

I have had my 2001 Alero since it was brand new off the lot. It has been a strong running car. It has had done work on it, most recently the mechanic I'm using has replaced the intake gasket, thermostat, hoses, and coolant reservoir because of the coolant leaking. After all that still having problems with the coolant leaking (but apparently not mixing in to the oil)....I've just been putting water in and I have to stop after driving about 10 minutes to refill the reservoir.
The mechanic was going to replace the cooling fans because he said they weren't working but then he hooked up a sensor machine and there were no issues, so he ended up replacing the radiator because he thought there might be a blockage causing the water to boil back up into the reservoir, and the car overheating. The car drives great, but after about 10 minutes there is a type of sputtering. The mechanic is saying that he has replaced everything that can be replaced in the cooling system and that he thinks the head gaskets are bad.

I have a 2001 Nissan Pathfinder SE with 160,000 miles. I took my car in for an overheating problem yesterday after I noticed the coolant was leaking out of my car. I needed a simple hose repair to fix the leak problem, but now they want to replace the temperature gauge because they say that it is still running hot due to: "temperature gauge is stuck and not letting the cold water in." He said that he fixed the hose and it is blowing the cool air to the motor, so the only problem could be the temperature gauge.
Within the past year, I replaced the radiator and hoses. He is saying the temperature gauge + labor would amount to around $300. The car is probably worth around $2250 for a dealer trade-in. I am planning on trading-in the Pathfinder towards the purchase of new one once I am able to present it to the dealer in workable condition. What to do?

My 2015 2.4L Hyundai Sonata randomly started overheating today. The coolant tank is full and it never did this before. The temperature gauge goes up and the information display says car has overheated.

Check out the pics, noticed car was overheating, let it cool down, got it home and found this broken hose (it was a crack in the hose before I broke it all the way taking the throttle body off). What is the part number for this hose and what else I should be looking for now that the car overheated?

I have a 2004 Honda Civic ex coupe. I have changed the thermostat (twice), fan sensor, temp. sensor. The fan works and when doing an oil change the oil looks normal. No white smoke coming out of my exhaust and I got two radiator flushes, no dirty coolant, and I have replaced the cabin filter. The car doesn't overheat as long as I keep my temperature on hot. If I were to change the temp. to cold it seems like the coolant goes into the reservoir, but it seems like it doesn't go back into the engine. The mechanic that did the flush said that the hoses doesn't to be clogged because the coolant that was removed was green. They stuck an air blower in the heater core hoses and to show that was not clogged as well. The AC worked, I haven't checked in about couple of months. Also when the car overheats there is no smoke coming from the engine. radiator has been burped as well.

I have a 1993 Mercury Cougar XR7 3.8 L V-6 with 138,000 miles that has been having overheating and coolant loss issues for the past 3 months. So far I have replaced the radiator (cracked), 2 thermostats (not opening), and the thermostat housing; which is where the mechanic said the leak was coming from. I don't have a visible leak now but it is still overheating after about 15 mins of driving it. I took it back to the same mechanic who said the sealant on the head gasket needed to be replaced.
As far as I know, there is no "sealant" ON the head gasket...the head gasket is the sealant. I took it to a different mechanic who said I have leaks in several of the coolant hoses. I can smell antifreeze every time I get out of my car, but I don't see any leaks. I am concerned I've blown the head gasket but the mechanic says they cannot test that until the hoses are fixed. Does this sound reliable? Could it be a hose issue and that's all?

I have a 1992 Toyota Celica I think I may have overheating problems every time i stop after driving a little while i can hear a boiling noise from where you put your coolant in and when i open it there is steam coming from the black hose that goes in it.
The funny thing is when i am driving the temperature gauge stays at 1/2 way and never passes it, also sometimes when i stop green and a bit clear liquid leaks on the ground on the side where the battery is.

I know my car has a leak. Blok check test confirmed. Symptoms:
Car overheats after driving for awhile but only intermittently
Overflow is filled almost to top after driving and has wet sides.
Coolant fails to return to engine.
Here is the interesting part. I removed the lid for over flow and took out the hose and exposed it to air. Then I took off rad cap. Instant suction and collapse of both lower and upper hoses. Why did this occur? Bad rad cap and or/ blockage?
