My car has white smoke coming from the exhaust


he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

Have anyone smelled an ammonia smell out of their exhaust system?


Possible engine coolant in exhaust..
Check fluid level in radiator (when engine cold)
Also check amount of coolant in reservoir.
If low, indication of possible head gasket failure.
Spark plug will possibly be fouled on cylinders affected.

I changed the turbo now white smoke coming out of my exhaust


This seems to be a symptom of a blown head gasket.
White exhaust smoke is an indication of water / coolant in the exhaust. The car running sluggish and using lots of fuel can be caused by compression loss.

Look at the coolant level color and smell (with cold engine - don't open the high pressure reservoir with engine hot as hot coolant may spray you in the face). If you have a blown gasket, the coolant color may become brownish and it may smell bad or the level will get lower even if you have just refilled the cooling system.

What you can also check for is bubbles in the reservoir. With engine cold, remove the reservoir cap. Start the engine. Try to rev the engine (or have someone do it) and observe if there are bubbles in the reservoir tank. If you see lots of bubbles, you have a blown gasket.

Coolant loss no leak


hi.

Check compression. If the leak is internal, then the most common cause is the head gasket. Water (or coolant) leaks internally through the worn head gasket reaching the cylinders where it gets vaporized. Symptoms are coolant fluid level going down, bad performance, loss of compression, overheating, white smoke because of vaporized coolant from exhaust, traces of fuel in coolant reservoir etc.

If head gasket is Ok and there is no overheating, then the leak is external. Check pump, radiator and coolant lines.

Regards.

Why is water shooting out of the cooling system overflow reservoir?


Sniff around the coolant reservoir for the scent of exhaust fumes and check the color of the coolant in the reservoir.
If you see discoloration or smell 'exhaust' type fumes, you may have a blown head gasket.

My 95 rr county is overheating. I replaced my thermostat and coolant doesnt leak. What can be causing the overheating?


the water pump may be defective, or the head gasket might be blown. Smell the exhaust and if it smells "sweet" - if so, have a cylinder leak-down test done to see if one of the head gaskets blew.

Lc prado overheat cause?


The turbo will not cause overheating.
Check the thermostat in the cooling system is working and then smell the coolant with the engine running. If you smell exhaust gases in the coolant it could be the head gasket.
