Why is antifreeze found in the tailpipe after starting car?

Antifreeze should never be found in the tailpipe of a car. If you find antifreeze in the tailpipe, it's a serious problem that indicates a leak in the engine or cooling system.

Here are some possible reasons why you may find antifreeze in the tailpipe:

- Head gasket failure: A blown head gasket can allow coolant to leak into the combustion chambers, where it can mix with the fuel and exhaust gases. This can lead to white or blue smoke coming from the tailpipe, as well as a loss of coolant and overheating.

- Cracked cylinder head: A cracked cylinder head can also allow coolant to leak into the combustion chambers. This can cause similar symptoms to a head gasket failure, including white or blue smoke from the tailpipe, a loss of coolant, and overheating.

- Faulty intake manifold gasket: A faulty intake manifold gasket can allow coolant to leak into the engine's intake manifold. This can cause a rough idle, stalling, and a loss of power. It can also lead to antifreeze in the tailpipe.

If you find antifreeze in the tailpipe of your car, it is important to have the problem diagnosed and repaired by a qualified mechanic as soon as possible to prevent further damage to the engine.
