I really need to do both trucks.
Should anything be avoided when cleaning the engine bay?
I've seen guys say to put a bag over the alternator and avoid the intake box.
I take it this should be done on a cold engine to avoid damage or do you use so little water that it wouldn't cool the block down fast anyways?
Would it hurt to use a degreaser on an old engine or would that just create more problems by loosening up dirt that may be plugging a leak? (I know I've got some good dirt/oil build-up on the front of my block)
Sorry for all the questions, but I don't want to fWONk things up....which is why I've never done it.
