Degreasing Engine?
 

So I went to walmart today & saw a engine degreaser for a good price. I was wondering what I needed to cover in the engine bay? It's a 1995 Nissan Maxima. I know to cover the battery, alternator, coilpacks & it has a stock intake so that won't be a problem. Also I was doing some reading just to find out on here everyone says let the engine run.....But on the can it says leave the engine off while it's cool...What should I do?

maf...air filter.....anything else eletronic and just spray very LIGHT mist of water.

That stuff works ok. Greased Lightning works much better. Just be careful with it and don't get it on the paint.

Thanks everyone
