Will oil in antifreeze hurt car?

Oil in antifreeze can be very harmful to your car. It can cause the antifreeze to become thick and sludgy, which can clog the radiator and cause the engine to overheat. It can also cause the water pump to fail, which can lead to the engine seizing up. In addition, oil can damage the seals and gaskets in the cooling system, causing leaks. If you suspect that there is oil in your antifreeze, it is important to have your car checked out by a mechanic as soon as possible.

Here are some of the specific problems that oil can cause in an engine:

* Overheating: Oil can prevent the antifreeze from circulating properly, which can cause the engine to overheat. This can lead to serious damage, including warped cylinder heads, cracked pistons, and melted bearings.

* Water pump failure: Oil can cause the water pump to fail, which can lead to the engine seizing up. The water pump is responsible for circulating the antifreeze throughout the engine, so if it fails, the engine will not be able to cool down properly.

* Leaks: Oil can damage the seals and gaskets in the cooling system, causing leaks. This can lead to the loss of coolant, which can cause the engine to overheat.

If you suspect that there is oil in your antifreeze, it is important to have your car checked out by a mechanic as soon as possible. The sooner the problem is diagnosed and fixed, the less damage it will do to your car.
