i want to clean my engine but i am not sure what to use and if there is anything that i need to cover up to stop water or anything like that from getting in it

 

take the plastic cover off the top, then if you do use engine degreaser on the rest of it or even if you spray it off with water make sure you leave the engine running!!! this will keep all the electrical going and will not have any problems restarting...

just make sure the engine is running when you spray it down and keep away from the computer in the front drivers side
