Is it OK to Wash the Engine Bay with Water?

If your car is old, I’ll advise desisting from using water to clean the engine due to how they were built.

However, modern-day vehicles come equipped with weatherproof connections that make them immune to water to some extent.

So, it’s perfectly OK to wash your new model car’s Engine Bay with low-pressure water but utilize an engine degreaser to be safer.

Is it Safe to Pressure wash the Engine Bay?

No, using high-pressure water to wash the engine bay will force moisture into seals or insulators covering the wiring and electrical component of the engine.
