Powerwashing Engine???

[tando]

A friend of mine told me that a good way to clean under the hood is to simply powerwash it. I contend that he is completely wrong as things like the alternator and such would cease to function after being inundated. Any comments??

i was wondering this also

do a search

I think the concensus was to not use high pressure.

cover all connections and use a cleaner and brush to get most of the work done, less intrusive

I've had it done twice by professional car washes and no problem either time.

definitley dont do it on the J30 engine, dont know what you drive. Probably not worth getting injector connectors corroded on Q either...

I take saran wrap and cover ALL electrical connectors.

Then you can go hog-wild with the cleaning. Be sure to use a blower on the engine immediately afterwards to blow all the excess water off (and out of the deep vee).

I've done on a few cars. This is tremendously helpful if you're getting ready for a major job.

I believe it's ok if you follow a few precautions.

Every part under the hood is designed to loosely waterproof. That is it's desinged to work outdoors.

Few parts are designed to stay wet for very long.Few parts really enjoy temp shocks either.

Here's my recommended method.

1. Get the car to the place with as cold engine as possible.2. Cover the distributor (if exists) and crank angle (these are key to the quick resart)3. Disconnect the battery.4. Wash it good. Keep in mind that from the top you really can only do so much below the top 16 inches. The soap is your friend. If you're washing in preperation from a major job, remember to wash the bay walls and railings good too5. Rinse with water, none of that spot free stuff.6. start it and run it (driving, until EVERYTHING is dry)7. The particular types will want to apply electrical gresee to all connectors. (the infiniti desgined connectors all have water barriers built in, but these can fall out)

For the last 10 years....I have taken mine to one of those DIY car washes...soaked it with their engine cleaner...and then power washed it..

The engine has never been very dirty so I don't have to hit it too hard.

I have done this every 6 months or so with no problems.

You do any covering to prepare it or did you just soak it?

My suggestion would be to get some simple green (or something like that) and get a small sponge, and wipe her down...... Then rinse/dry with a cold towel.....

Then, whenever you wash the car, you can just rinse all the stuff off with a gentle shower......
