I NEED to clean my engine i saw the link to autopia (very useful) but im not sure what engine parts i need to cover for my 99 gt. If anyone has a link with a step-by-step process for a GP GT let me know
Thanks,
Bobby

I'll tell you what I do.

I remove my hood heat shield thing (I dont know the actual term for it)
I cover up my open cone air filter with the large gallon sized zip lock bags
I then stick about $5 in the car wash and go to tow on the engine bay and under carriage. People laugh, but its not uncommon to see me nearly flat on my belly spraying down the underside of the whole car, including the engine bay.

I rinse everything down, remove the air filter cover, re-install the heat shield thingy and once everything has dried out really well I wipe everything I can with a rag and Pledge dusting polish. Pledge does a MUCH better job because it does not attract dust like Armor All does. I wipe down all the rubber hoses, vacuum lines, braces, everything I can including CV boots inner and outer.

Im not quite as fanatical as those the put their cars in car shows all the time but Im not far behind.

It whines a lot, but I like it.

The only limitation you will ever face in life is yourself!

i keep seeing this question, maybe someone should do a write-up...(hint hint^^^^)

I've got Boost!! I've got only 1.5* KR left my poor L36 block.....

LOL. Yeah, perhaps I should do that. But right now it would have to wait until I get the tranny replaced and the car off jack stands.

I have a questions about this, since I've been showered by a salt truck, I would lve to have a clean engine bay.

So you don't have to cover the alternator or PCM? Would the long term effects of hosing down a electronic engine mgmt car, be massive electrical problems much later?

Something I learned about engine cleaning on a car with Headers.... DONT repeatedly wash it off without letting things dry out or hot! My cousin has SLP headers on his car and always rinses off the engine and after just months rust spots started under the coating. A local performance coating place said it was from the minerals in the water being baked into the poors of the coating and speeding up oxidizing which causes the rust.

I've always heard to cover the alternator and coils, but some people don't. If the PCM is exposed it won't hurt to cover it. Aluminum foil works well. There is no harm is washing the engine compartment, if it couldn't take a little water we'd all be in trouble. That is why there are weatherpack connectors under there. That said though use common sense. Don't spray with high pressure and try to avoid electrical components (which is kinda hard with modern cars).

the first few times I washed it with a pressure washer and degreaser, and no problems from that, Carmax steam cleans all the engine bays, and that seems to be ok..... but do what you feel comfortable with, if it makes you feel better to cover those components, by all means cover em

when i d mine i cover the alt coils and tb and use purple poer for de greaser it works good

Carefull of the purple stuff on Aluminum. Some brands have a warning on the back label not to use on Alkaline sensitive metals such as aluminum. I use simple green, a toothbrush, and Low pressure water. Your car gets wet in the rain right? Just use good sense and go for it. A clean engine runs cooler and a clean engine makes any future issues fast and easy to spot.
