power wash

[geoff thomas]

Hi guys how we all doing?
I am looking for some advice, after my truck decided it was going to die yesterday i think i have diagnosed the problem, which is a good service and also CPS replacement. so anyway the advice i am looking for, when i looked under my truck it is not so clean dirt oil etc. so is it ok to pressure wash the underside of the truck and is there any parts i should avoid if it is ok to do so?
Thanks
Geoff

I use Simple Green and a water hose. It cleans it real well. Some people talk about some purple cleaner, too.

As far as what to avoid, I just spray water gently all over avoiding my air filter and let it dry before starting. This works for me. If it's real gunked up, it may take 2 applications of Simple Green.

ditto here, i use the powerwasher under the truck but the top half always a hose and lots of degreaser.

Pressure washing the underside is fine, but I wouldn't pressure wash the top unless you have the motor out and all the holes plugged up. I agree with using simple green and a hose.

I use a degreaser in a white jug it is a bio degreaser and a hose to the hot water tank every year keeps it real clean and shinny. Just don't do if the wife is home it's hard to explain it to her so she understands.

Simple green will damage aluminum if left to long so be careful. I use the purple stuff or the Orange stuff and it works great. Get the engine warm, not hot, spray degreaser, let sit for 10-15 min, cover alt, and PS cap, then spray with a high pressure garden hose, no pressure washer unless you are just asking for problems. Then leave the hood open all day and allow it to dry out before you try to start it. Then spray it down with engine detailer ( Silicone Spray)
