Can pressure washing the whole underneath of my hood do any damage? Its so dirty and oily its ridiculous. Is there a good cleaning agent I could use?

gunk. thats what ive used in the past. douse the engine in it aand spray away. but i wouldnt use a high pressure. efi or carb?

g_mau18

its an efi, so I can cover everything with gunk? belts and all? and just spray it off?

cuz im thinking that horrible squeeling noise is from oil and mud all up in the belts

ive done it in the past with motors. i would be selective where i spray tho. stay away from direct blasts on electronics and hose joints but i think you can spray it down pretty good. dont have 10 bucks for a new belt? if you have that much oil and grease on your motor i would look for leaks.

no i drove it with the oil cap off, dont ask me why...thats my buisness not yours. but hmm maybe I could just get another belt. ill try spraying it down then buying another belt, and the screaming seems to be a/c related when I turn it on it starts singing then when its off it kinda quiets down, do you know what that could be?

if you got oil on the belt it definatly be that, it starts squeeling more because the pully on the pump is no longer free wheeling when you turn the ac on. changing the belt should handle the problem for you. lol dont worry about the oil cap i did that the day i got my truck lol had to stuff a glove in the whole to get it over to napa to get a cap...

right on man thanks, so ill clean the pulleys and all that and change the belt. I should be the newb not you.

eh im just giving my oppinion thats all. seems most of us forget basic things when its our own crap thats having trouble. thats what the site is for. everyone now and then needs a slap up side the head to get it straight
