Overheating hi, our trooper is overheating, had the radiator and fan replaced. Blowing white smoke from exhaust. We can smell coolant burning. The radiator empties, but coolant is still 3/4 full. After radiator was replaced, overheated again but mechanic has failed to find the problem. We watched the temp gauge and had no problem for 1 week. even drove it on a 200 mile trip. Now we can't drive it 3 miles! Help!!!

Sounds like you may have a blown head gasket,white smoke is usually caused by this,driving it can cause major damage,best to have towed to a shop.

SOURCE: White smoke exhaust

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....

SOURCE: Overheating

Did the smoke arrive immediately, or after the engine got to temp? Did you recheck the radiator fluid. From initial sounds, you may have ran too hot for one reason or another (low coolant, leak, bad thermostat, etc.) and now have a bad head gasket, or worse, a cracked head. This is not unrepairable and may be resolved with a GOOD block sealant with a lot of luck. FOLLOW INSTRUCTIONS TO A "T".
In any event, it would appear from your description that coolant is entering the exhaust. You can verify by checking the coolant level again and also carefully placing your hand, or a piece of plastic inches away from the exhaust. Coolant will be obviously detected if this is the issue.
If you are somewhat mechanical, you can remove the top half of the engine to replace gaskets, and remove the heads to be shaved down at a machine shop. they will tell you if the heads must be replaced. I have done this once, so I am no expert, but I survived the experience.

Have you tested out your fans? Check your fuses and the actual fuse box. Could be a bad fuse or bad fuse box because I had that happen to me. The fuse was okay (it still had some kind of power going to it ) but the actual box underneath was melted.

Hi, My Audi A6 is overheating and the coolant is


Fan turns on when you turn the AC on, and when coolant gets too hot (over middle of the instrument).
White smoke in exhaust means coolant gets into the cylinder, typically head gasket or crack.
Is the upper radiator hose (the one that goes to the coolant expansion tank getting very hot? Observe when car is warming up. When coolant temp gauge needle is in the middle, the upper radiator hose should get warm; also the radiator (you can touch the top and check) should get warm at that time. The means that the thermostat opened as it should (when engine warmed up). If it does NOT get hot, then the thermostat is stuck closed, which can lead to overheating. Still, the fans should kick in.

White smoke at exhoust and puch water out of the radiator


Blown head gasket or cracked head. I'll guess this happened after overheating the engine. The compression of the affected cylinder will blow coolant out of the radiator and coolant in the cylinder burning shows up as white smoke in the exhaust.12_24_2012_1_46_50_pm.png

99 Grand Am Smoke Exhaust


I'm sorry to say your engine may be cooked.
Since you are adding both oil and coolant, and the color of the smoke is gray or white, you have the signs of the engine burning coolant.
The common cause is a leaking head gasket.

Overheat and now wont start what could it be?


Depending on how severely it overheated, it could be that the head gasket is damaged and in need of repair. There are a few different ways of diagnosing the head gasket, the simplest is to crank the engine while you have a helper smell the exhaust pipe looking for either blue smoke (burning oil) or a white smoke and sweet smell (burning coolant). If you have a radiator cap your should remove it and look for oil (signs of blown head gasket) or a brown color in the coolant. Other options are to do a compression check on the engine.

the sweet smell is the motor burning off the residual coolant on the components that got sprayed with coolant.if the car got overheated enough it may have damaged the head gasket and is now burning oil due to the over heating.or there is a mechanical problem due to the overheating(ring problem,valve problem,etc.)if its burning oil then it can cause an 02 problem as the sensor will get coated with what ever is coming out of the exhaust.the heat sensor is part of the 02 sensor that warms the sensor up so the computer will go into closed loop sooner and help with fuel mileage.

1993 Mercury Sable, white smoke, overheating


Good Day,

White some indicated that coolant is burning off. It could just be a simple leak which is burning off of the hot motor. It could also be a bad head gasket(probably what you don't wanna hear), One indication that it is the head gasket is white smoke coming out of the exhaust, this happens as coolant gets into the oil and is burned off then exhausted out the back. Possible causes for the overheating include, low coolant, coolant leak, thermostat, water pump and or water pump belt, or head gasket.

If I were you I would drain and flush the radiator, then fill it with new coolant, and change the thermostat, provided you have no white smoke coming out the exhaust.

hope this helps for now

Hi,

Sounds typical of head gasket failure.

With this you get oil into cylinders / water into cylinders, burning oil, loosing water - but no leaks. "boiling" of radiator and overflows.

Check your coolant and oil levels - they will be low.

Get a few quotes for a head gasket replacement - and timing belt change, as it has to come off when you do this anyway & no sense putting an old one on - they often snap if retensioned.

If this solves your problem, please take a moment to rate as Fixya! thanks.
