Water Damage to Engine Damage: A Guide to Prevention and Repair
Water damage to an engine is one of the most severe and complex mechanical issues that a vehicle owner can encounter. Whether caused by driving through deep water, heavy flooding, or other unforeseen circumstances, such damage can lead to significant performance issues or even render the engine inoperable.
The Risks of Water Exposure to a Car Engine
Water exposure to a car engine can cause a range of problems, including hydrolocking, which eventually leads to engine failure. Water in the engine can also cause oil, petrol, or transmission fluid contamination, electrical faults, or rust. These potential problems are very dangerous and can result in engine malfunctions.
Where to Look for Water Damage
When inspecting a vehicle for water damage, it's essential to check the air filter and intake. If those are wet, it's safe to assume for the worst. Look for other places where water could have leaked inside the engine. Next, check the oil dipstick. If you see that there's more oil than there should be, or if it looks milky, then you probably have water in the crankcase.
The Consequences of Water Damage to a Car Engine
Water damage to a car engine can have severe consequences, including:
- Engine failure
- Hydrolocking
- Oil, petrol, or transmission fluid contamination
