hi i want to clean my engine and i would like to know whats the best way to do it???

 

There's a thread in Show and Shine about this.

 

Internal - Seafoam

External - Simple Green and elbow grease

 

A hand held steam cleaner! Make sure that you cover the opti spark with a rag so that you don't get it wet!!!!!! Good luck.

 

I don't clean mine much for fear of accidentally getting the opti wet. But when I do... I put a yellow trashbag over the opti then use a hose and a spray bottle of diluted simple green.

 

Externally, I use Gunk engine cleaner. Just spray it down, let it sit for 15 minutes, and hose it off. Don't worry about getting the Opti wet. It sees more water driving in a rain storm. It won't hurt it.

My Blazer has 360,000 miles and the Gunk does such a good job of cleaning grease and dirt that my block is actually rusting because it so clean and dry.

 

I washed mine last year with just a garden hose and some degreaser and all of a sudden it ran like crap... We figured it out though it was my TPS went bad. Shifting,rpm and idle was all messed up.. Will not do that again.

 

sprayed mine with acid degreaser and then watched the detail kid spray it down with the power washer......all is well

 

you should cover the alternator too, it could get trashed if stuff gets inside it

 

Don't do it.if you have dust,use a brush.My02.Leave the engine alone.

 

yeah - I agree w/that at least compared w/hosing it down...

I use very little fluid - bit of water/simple green on a rag to wipe off... maybe a little lucas detailing spray on the hoses etc... not good to go in there w/alot of water let alone a hose imho
