Yes, cover the alternators and wire harnesses as well. Basically anything important that you feel should be covered, the bulk of the engine is metal, so not getting those other parts clean won't matter too much, Atleast you can go over with a cloth and touch those spots up.
Hmm, maybe he got some water in the spark plugs or something, thats the only reason I'd think of it not starting.
If I were you, I'd just use the simple green, you can control the spray and won't have to cover up all that stuff!
Yeah mine has 141k on it and hasn't been clean in a while. I had the water pump and a hose go bad on my and I still haven't cleaned it since. Saw your thread and got pretty envious. Decided I had to have my truck looking purty too. Got to treat her right with the high miles. Want her to feel good.
So pretty much just make sure you have the intake and the distributor covered before you spray water on the engine? Any other electrical parts to be worried about, like the alternator or the battery or wire harnesses?
I had a buddy clean his engine one time and couldn't start his car for a week. I guess it had to dry out.
Thanks! it has 117k miles on it, you would never guess! I started with using "Simple Green". It is great at breaking grime down. I simply spray some where it is gunky, i'll brush it or use a cloth and wipe it away. Simple as that!
You can even use a soap/water solution. The engine is quite simple to clean actually.
I was checking out your thread on your build log and noticed that your engine compartment is immaculate! Do you have any tricks for cleaning it and keepin it that way? Mine is looking kind of rough right now. I have been thinking of paying a dealer to steam clean it like they would a car they were trying to sell but I would rather save the money and do it myself. Any tips?
