There are some really good reasons why you should endeavor to keep your car engine clean. One of the most important reasons is it’s much easier to find a fluid leak such as a leaky valve-cover gasket so that a small problem can be isolated and repaired before it becomes a big one. It also helps you to notice worn or torn belts, prevent engine rust. In addition, because oil and grease can accelerate the wear of rubber hoses and plastic parts, cleaning off the gunk may save on repairs. And a clean engine makes things a lot less messy when under the hood.
A clean engine runs smoother and a little cooler because of the removed gunk formed by dirt, oil and grease. It’s recommended to use degreaser products–this comes mostly in spray form, and tools such as a vacuum with a small nozzle, compressed air or a toothbrush to get at hard-to-reach spots. These are preferable to blasting an engine with a high-pressure hose or steam cleaning an engine, because moisture can damage electrical parts.
The cosmetic appeal of a clean engine will probably be the biggest payback. Most used cars are thoroughly detailed before being put up for sale, including many sold by private owners, so buyers have come to expect to see a clean engine when they shop. A dirty engine on a used car will hurt its curb appeal.
