Default cleaning engine

Hello,Vet. freinds Not been on in awhile so i will get to the point. Someone please tell me a good cleaner to use on my 99 vet engine. I know some cleaners will mess with the sensors. So what is the best stuff. My engine is not real dirty but still needs cleaning.Help me if you can. Merry Christmas and Happy New Year. Smiley

I do everything by hand, takes time but its worth it in the end. This way you can use what you want and not worry about sensors.

Simple Green works awesome, IMHO. All Natural, non-toxic and won't fade of harm plastic or wires.

any suggestions on the best way to go about cleaning it? Mine has some misty dirt and grime on it and I've been trying to figure out the easiest less messy way to go about it.

Use Simple Green and hose off gently. Avoiding getting water in the battery area as the ECM is below the battery.

Get the engine warm (not hot); spray with SG & let soak 5-10 min. Rinse thoroughly.

If it won't just wipe off, use some Simple Green and then just let the water flow over the engine where you need to wash it off. Try and avoid any heavy spray action as it may get into some sensitive electronic parts.

SIMPLE GREEN will work well as described, used in diluted strength not full strength. If you have some really greasy areas, use aerosol brake cleaner to break up the grease, followed by the SIMPLE GREEN. The brake cleaner will leave no residue behind. Denatured alcohol on multiple shop rags/old tooth brush works well, also. Be careful, it'll freeze your hands!

And once you finish it the first time, all you have to do is wipe it down each time you wash the car. It won't take long for the follow up cleanings. Mine is over 100k as of this week and you could eat out of the engine bay.

Like others have said, use simple green on any stubborn issues with a rag.

Once clean, if you give it a quick wipe now and then with something like Armoral, it keeps things looking pretty spiffy!

But clean with caution, go easy on the high water pressure, you could cause some electrical damage.

Specifically what "sensors" and "electrical parts" should be avoided? I have been spraying engine cleaner all over the engine compartment and using a hose to rinse it off (followed by a hand dry)about twice a year for the last 6 years without a realized problem yet. Have I just been lucky or have I probably messed something up that just has not presented itself yet?

I would not do this. There is a known problem with water getting into the knock sensors under the intake manifold. The Technical Bulletin has you make a "dam" out of RTV (?) to resolve. Also too many other sensors.
