I'm not sure if I would warm the motor up for that long, I normally start it up for 3-5 minutes (however long it takes it to get WARM to the touch, not hot, I think after 15 minutes the motor would be fairly hot). 5 minutes is about right for a fairly dirty motor, just make sure to keep the solution from caking on, so if you see it drying, keep applying it for the 5 minutes (lightly).OldTimer said:This looks so easy that I will try it this weekend. Since so many guys have advocated Simple Green I bought some to degrease as I do have a little build up from when I had a breather on my passenger side valve cover. So help out a first-timer here... is this a good 10-Step sequence?
1. Warm up engine for say 15 minutes?
2. Wrap exposed air filter with plastic.
2. Lightly spray some water on the engine.
3. Spray on the Simple Green and let sit for 5 minutes?
4. Use a parts brush to help loosen caked on gunk.
5. Lightly rinse with a garden hose.
6. Blow off excess water with a air hose or a leaf vacuum.
7. Apply the F21 on all exposed surfaces and close the hood.
8. After 15-20 minutes open the hood and wipe down everything.
9. Touch up areas with a rag and F21 sprayed onto it.
10. Re-start the engine to make sure all is well.
I'm not nuts about the concept of using a water powerspray (mine is 2600 psi) on an engine that might not like water forced into too many crevices... but that's just me. I had read where several guys have used their leaf blowers to blow out all the water. Typically, these blowers crank out 150-200 mph breeze that will evacuate almost any/all water droplets. My concern is obviously the plugs and coils... anyone want to comment on that?
As long as you dont spray the pressure cleaner directly into anything, for an extended period of time, you *shouldn't* have a problem, I never have, all I do is keep the nozzle on the widest setting, and spray 3-4 feet away from the motor at all times, sweeping quickly over the motor, just until all of the degreaser/soap is gone....
You may want to get a bunch of brushes and agitate the degreaser in any dirty spots, and pay special attention to areas with a lot of plastic or other material showing.
After you're done rinsing, you really shouldnt have to blow the water off, just spray the foam everywhere, and start the motor back up for a few minutes until its dry...This is where any water left over in the coils/plugs, and any other sensitive crevices will, evaporate from the heat.
You really shouldn't have a problem with powder coated surfaces, the only thing I could see messing with a powder coat is sandblasting, or vigorous scrubbing with an abrasive tool/brush, or a really heavy acid???zeus201 said:
