Pressure washer?

[graphikg]

I have cleaned my uderbody plastic (under my oil pan) and I loved it since it was all greased and dirty. But now I want to clean my engine bay and my diff pumpkin that is thick with grease. Can I do this? Or would it do harm?

i wouldn't do the engine bay with the pressure washer...might be too strong and damage something...just use a spray on engine cleaner degreaser and just wash off with a hose, and use a brush for the hard areas.

My neighbor does his cars. I think he just covers the alternator and fuse box. I've never done it. simple green and steam is all thats needed.

What about the differential pumpkin? Can I do that wirh a pressure washer?

You can probably do the diff/pig/pumpkin/whatever and you'll be fine. The only thing I could see that might get damaged (and you'd have to try) is the speed sensor that plugs into the back of it.

When I bought my car I bought a can of engine degreaser from my FLAPS and took the car to a RediWash. I put a couple of plastic bags over the fusebox, distributor, and alternator then let the degreaser soak for 15min. Pumped the machine full of quarters and went at it. The whole process works pretty well - I've done it on several of my cars. You just need to be careful around some of the more delicate parts. I usually let the car drip-dry for ten minutes and dry any electronics with a towel. When you start the car up it will smoke a bit with any water and left over degreaser on the the motor and it will stink. Once you drive it around it'll burn off and you'll have a clean motor!

If you pressurewash the diff, make sure you cover up the vent hole on the little chimney-looking thing on they rear upper part of the diff.
