What does it mean when your exhaust smells like coolant?
What does it mean when your exhaust smells like coolant?
If you’re absolutely sure that you smell coolant out of your exhaust pipe, then that means it’s leaking into one or more combustion chambers, getting burned up and emitted out of the exhaust.
What does it mean if you have exhaust gases in your coolant?
Exhaust gases in your engine’s coolant are usually a sign of a blown head gasket or cracked cylinder head. Continuing to operate your vehicle in either of these cases will quickly lead to full engine failure.
Where does the coolant go after blowing the head gasket?
Coolant either leaks past the head gasket out of the engine or past the head gasket into the cylinder and combustion chamber. If you have an external leak you will notice coolant leaking from in between your engine block and the head. This usually will happen just below the exhaust manifold or the intake manifold.
What to do if coolant leaks from exhaust manifold?
If this happens you will see white smoke coming from the exhaust. You can do a temporary fix on type of leak by adding a sealer into the cooling system. It may seal the leak if it is not extensive. You will still need to replace the head gasket but you will be able to get by for a short while.
What causes coolant to leak out of the intake gasket?
This is an indication that coolant is leaking into the oil. This leakage could be generated by a cracked cylinder head, block or a leaking intake manifold (in some cases) the intake gasket is also prone to this kind of failure. Note: A small amount of moisture maybe present inside an engine that doesn’t get used much which is normal.
What causes exhaust gas in the coolant reservoir?
Besides allowing coolant into the combustion chamber, an internal head gasket leak allows exhaust gases into the coolant. This can cause bubbles to be in the radiator or coolant reservoir making the coolant look like it’s boiling even when it’s cold. Click to see full answer.

Can you smell exhaust from a blown head gasket?
You can generally smell the exhaust in the coolant if you lift the coolant cap as well, with a blown head gasket. One of the comments below only partially answers a blown head gasket symptoms. It depends on how the head gasket has failed.
Why is antifreeze coming out of the exhaust?
If it is the cylinder head/gasket you will find the cooling system will rapidly over-pressurise and may possibly have a cylinder misfire on the affected cylinder. Squeeze the top radiator hose after starting the engine and giving it a good rev; if the hose is very hard you have a blown head gasket.
