   • How To Clean An Engine  
A mechanic will feel better working on a clean engine. Keep in mind the engine in your car is their desk. By cleaning your engine bay you will also be able to detect oil leaks sooner and by being underneath your hood you might catch one of your fluids getting low. It always a good idea to check inside your engine compartment. When it comes time to sell your car the prospective buyer will no doubt open the hood. If the engine is dirty the buyer will assume you did not take care of your car regardless of how well you have kept it maintained. If the the engine is clean the assumption will be that you did take care of your car and it will sell faster and for better money. Also in this video a rainbow appears at the end in front of my house.
