I want to clean my engine up a little bit what do I do? Is it ok to just pressure wash it?

 

what I did on my 2002 V6. I would warm the engine (Not Hott) with a spray bottle hit everything with a combination of Simple Green and water, wait a few minutes then lightly rinse off the residue.

 

I wouldn't use a pressure washer. COPs don't like getting wet along with lots of other electrical components. I would use some simple green and a rag.

There have been a few posts written here where folks used a pressure washer to clean the engine. One could not get his truck restarted for a couple of days. After removing all connectors and verifying they were dried out, he gave up and had it towed to a dealer. He never did post what had to be done to finally get it running again.

As already stated, the electrical connectors and sensors under the hood do not like water.

 

I spray it down with simple green or purple power then spray it lightly with water. I haven't had a problem with getting water in anything so far. Just don't shoot it with a hard stream.

 

Should the pickup be running or off when I spray it with the hose?

 

Running; in case it won't restart to take it to a service place to correct any water damage.

 

The problems usually happen when rubber starts drying out. On a newer truck, it's not usually something you have to worry about.

 

if it's running, how do you know it's not gonna restart until you turn it off and try to restart it? Then at that point, if it doesn't restart, you won't be able to get it to a service place besides having it towed.

In any event, I've never had a problem pressure washing my 5.4, although, Ive only done it a handful of times.

 

You usually notice it spittin' and spudderin'. My '90 Jeep Comanche started, but ran a little rough. When I got to where I was going, it stayed there overnight until it dried out.
