Hi:

I was wondering what is the proper way to wash the engine. Which part do you recomend to cover before spraying the water into the engine bay. What typle of products to use to get those gunk out? Do I need to have the engine runs while spaying the water into the engine bay? Do I need pressure washer or just regular hose will do the job?

Thanks in advance

There are many posts on this topic. Search using the advance function for 993's. Nothing to it!

Thank you. I will try and use the search botton.

As a short cut, most people cover the air intake and distributors, then spray the engine with simply green (some cut with 1/2 water). Let sit, repeat again, then rinse gently with hose on 'shower' spray. DO NOT use a pressure washer. If you're **** (ref: Andreas), use a toothbrush to get at tough spots. Polish the black plastic stuff to taste, see your local car care store for product.

THanks you for your suggestion. I did a search (somthing I really not aware we have that function ..I dont have much knowledge on computer and how to use it well) and find out many post about how to clean the engine. Guess we all learn somthing new everyday =)

When I've cleaned up my engine and compartment I've done the following:

Covered the two distributors and air box intake box with large baggies

Used S21 cleaner. Less caustic than simple Green and leaves no residue

Used a stiff bristled parts cleaning brush from any auto parts store. Pretty much gets to all the nook and crannies.

Gently turned on the garden hose and hosed off the S21. Never use a pressure washer.

Engine comes out pretty spotless.

Well, I do use a pressure washer, but set on the gentlest spray, one that I can hold my hand in, not the one that will peel the skin off the neighbor's cat. I think the pressure washer rinses off the residue (I use Simple Green as a solvent) better with less water.

I get the engine warm first, but not hot, to help vaporize moisture. Then as soon as I complete wash/rinse, and blot the major water puddles off the engine, I crank it up and let it run to finish burning off the water.

I put a rag in the intake horn to protect the air filter, nothing on anything else, but I don't dwell on any electronic parts with the water spray.

All right, all right. Since we are in the holidays and are going to provide the info anyway, I recommend you seek out a spray bottle of 303 (brand) Aerospace Protectant. After cleaning the motor using the above recommendations, spray copious amounts of the stuff on the motor and all plastic parts. After it dries it repels dust and dirt as well as keeps the motor looking great.

Happy Holidays!

I just did mine the other week. I sprayed a 1:1 mix of Simple Green over the entire engine. Ten I let it sit for 10 minutes or so before thoroughly rinsing everything. I cover nothing, yet I also take care not to spray into the fan blades or into the air cleaner. Once everything is dry, I swamp the engine compartment in 303.....

No toothbrushes for this junker, Matt!

--I was taught if you use anything with silicone under the hood (even RTV), don't start the car for a day since the silicone can foul O2 sensor - wonder if that's true. Anyway, I stay away from silicone under the hood - you might check the products you intend to use.

Again, thanks for all the response. I will be doing mine this weekend. Happy holiday!!

There is absolutely no harm in doing so, at the contrary.
The fan takes in dust, debris, with a good squirt of polution, and deposits a thick layer of suit on the top of the engine. With a little moisture, this stuff sticks hard, especially between the cylinders, and top cylinder fins.
When I changed my alternator, I cleaned out all the gunk.
When you spray in the fan blades from below, the water goes directly on the top of the engine, and goes down between the cylinders.
Ever since, I stick a hose between the bottom fan blades for a couple of minutes each month (ENGINE COLD).
The alternator will not get wet because it is englobed in the core of the fan, even if it gets wet, there is zero harm.

Since hazardous stuff like SW airbags, detailing sprays and chemicals such as Simple Green seem to be difficult to ship across the pond to Europe, do you any of you Europeans know of any equivalent product that can be used for the same purpose? Is Simple Green just a degreaser or is there more to it? I have found a distributor for Aerospace 303 protectant so that should be fine but I'm sure there are other products available over here as a substitute for the Simple Green stuff..

Werth citrus degreaser works well. German. You should be able to find it.
