Coolant Leak: If you notice a significant amount of water coming from the exhaust pipe, it could indicate a coolant leak. Coolant is a liquid that helps to keep the engine cool, and if there is a leak, it can mix with the exhaust gases and vaporize. This can cause white or blue smoke to come from the exhaust pipe, as well as a sweet smell.
Head Gasket Failure: A head gasket failure can also cause water to come from the exhaust pipe. The head gasket is a seal between the engine block and the cylinder head, and if it fails, it can allow coolant to leak into the combustion chambers. This can cause the engine to overheat and can also cause the exhaust gases to mix with the coolant, which can lead to white smoke and a sweet smell coming from the exhaust pipe.
Faulty Emissions System: A faulty emissions system can also cause water to come from the exhaust pipe. The emissions system is responsible for cleaning the exhaust gases before they are released into the atmosphere, and if it is not working properly, it can allow water vapor to escape from the exhaust pipe.
If you are concerned about water coming from the exhaust pipe, it is best to have your vehicle inspected by a qualified mechanic. They can determine the cause of the problem and recommend the necessary repairs.
