when ur engine is all muddy and u decide to wash it is it best to leave the engine runnin or shut it off??? this has always been a iffy situation with me cause so many people say oo leave it runnin then others say shut it off or u could do damage. so whats the real way

 

Off. Cool. Stay away from the Power Distribution Box. Dont drown the alternator (a little water wont hurt it, just dont flood it). Low/Med Pressure. Thats it.

I'v been washing mine that way for years.. works great. In your manual there is a diagram of what not to soak, might want to review that just for good measure. Dont use harsh chemicles, Orange Clean or Simple Green work best.

Good luck!

 

read the book it comes with.

but ive done it both ways running and off, i dont think it really matters, just dont concentratethe spray in one place.

 

off..make sure and let everything cool down first, a red hot block with cold water sprayed on it isnt a good combo..simple green works awsome....

 

thanks guys someone was tellin me about hot block and cold water today and i was like next time ill make sure the engine isnt that hottt lol

 

you would have to completly submerge the block inorder for it to cause problems. ive washed mine time after time when it was hot, no issues.

 

I've done mine both ways.
If i am going to clean it really good, i turn it off.
I also cover the intake and the distributer cap with a bag.
After i read the manual, it says to turn it off and cover all the electrical parts.

 

Your truck has a distributor cap?
