HeyHoward==If it is coolant the engine will overheat quickly and the engine will smoke white smoke. The head gaskets will need replaced. It can be normal condensation if it is pretty clear water. Good luck, Joe

Its not coolant. It is vapor that condensed and formed into water as your muffler cooled from the last time it was used. Could be indication of a bad head gasket

Doesn't have to be anything wrong. Some condensation is a natural result of the combustion process.

Your coolant pump is behined the fan, you will have to replace the water pump.

You may have a blown head gasket.

the reason you here noise from your muffler are because less pressure from your engine is going fast.

The muffler has failed. That is what muffled the sound on some vehicles.

Your headgasket is bad, coolant is getting into the combustion chamber, hence the thick white smoke and fluid. had that happen to my dads thunderbird a few years ago

The smoke from your muffler has a smell because what is coming out of the muffler is the products of the incomplete combustion of your fuel. Some of those products are gases and vapors that have color and some are dark but small particles - that is what you call smoke. But some of what comes out are various chemicals that your nose detects as odors.

Replace If it has a hole or leak in it, replace it. A leaking muffler is a very dangerous thing. I know, I had a very serious accident from a leaking muffler. Carbon Monxide is a odorless, tasteless, killer. It put me to sleep and I never saw it coming. I did however wake up just in time to see the tree coming, and was unable to miss it. Spent 2 weeks in the hospital over a $20 muffler. Get yourself a new muffler.

Low coolant in coolant recovery tank or radiator or defective sensor

If there's a hole in the muffler, you will begin to hear a loud roaring noise when you drive. You also will notice toxic fumes coming out from the muffler. These fumes can cause headaches, dizziness, and other health problems when inhaled.

Varies from car to car. Is it just the muffler or are the pipes a problem? Find out where the noise is coming from, check for holes, black soot or just air coming out. Be careful, it might be hot, expecially the converter & front pipe sections.

the water pump gaskets start to leak (right or left, or both) and the coolant runs down the block to the oil pan/ block joint and appears to be coming from the oil pan. follow the leak closely, and you will probably see that it is coming from above the oil pan in the front.

A little water coming from the muffler for the first few minutes after you start the car is normal. Water vapor condenses inside the exhaust system when you stop the motor, and is expelled the next time you start. If there is a lot of water coming out, and it keeps coming even after the car is thoroughly warmed up, then it could be coolant leaking into the cylinders from a bad head gasket or a cracked block. You can have a mechanic do a pressure test on your cooling system to test for this. He also can test for the presence of exhaust gasses in the cooling system.

There isn't much a person can do to stop the stinky smell of exhaust from the muffler. This smell, sometimes like sulphur or rotten eggs, is a by-product of the fuels burned.

To muffle the sounds of the engine /exhaust coming out take it off and see how it sounds!

Bad head gasket? Oil mixing with coolant?

User Avatar

Assuming there is coolant in the engine the most likely cause is a build up of sediment behind the coolant drain or in the coolant drain tap itself.

User Avatar

White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Most likely cause is a blown head gasket, cracked heard, or both. STOP driving this car until you can have it repaired or you will destroy the engine.
