your drain. Use a trigger sprayer and spray everything when the engine is cold. Use a stiff brush to loosen up thick grease. Respray the Simple Green periodically to keep things wet.

Wait a few minutes until it starts to dry, then hit it with a spray pattern from your hose. Don't use full force on your hose near electrical components. Use brush where necessary.

Beautiful engine bay.

(DO NOT spray cold water from your hose on a hot engine. Bad things can happen)
