Is it Ok to Pressure Wash a Car Engine?

Pressure washing is a great way to clean the exterior of your car, but can you use it to clean the engine as well? The answer is a bit more complicated than you might think.

On the one hand, pressure washing can be a very effective way to remove dirt and grime from an engine. The high-pressure water can reach into all the nooks and crannies, and it can dislodge even the most stubborn dirt.

On the other hand, pressure washing can also be harmful to an engine if it is not done properly. The high-pressure water can damage sensitive electrical components, and it can also force water into places where it should not be.
