The engine compartment is not designed for a lot of water – you could be getting water into areas where it shouldn’t be and it can cause corrosion. Water could get into the alternator or the engine sensors, causing damage. It can also push dirt onto belts, thereby causing squeaks. If you’re really unfortunate, water could get into your engine through the induction system, from around the air cleaner. It’s unlikely, but you could force water into the cylinders and cause huge damage. Anything that gets wet should be dried, ideally with compressed air, and then by running the engine until everything dries out.

But to answer your question, washing the engine depends on if the engine itself is cold, warm or hot. Using warm or cool water on a hot engine could cool things too fast, stressing the metal and, potentially, causing cracks. So I'd advise you use lukewarm soapy water to wash your engine.

My dad taught me to use either petrol or diesel to wash my engine, though I prefer using diesel.

Marshalrhino:

damn! U're knowledge about cars is vast nd so amazing. What did u study?

Marshalrhino:

why do u prefer diesel?

MsDelilah:


Petrol is a solvent. It has a way of removing protective oils from parts. Diesel doesn't.

Besides, if anything goes wrong, petrol burns faster than diesel.

MsDelilah:


I studied Economics. But I'm an avid reader of Car magazines.
