Okay I think I'll take precautions with the intake electrical and fuse box will get covered up and anything else I see might need it thanks for the help

 

I wash mine all the time. I use Purple Power mixed 50/50 with water and spray everything off. After it is dry I come back with any tire shine and spray everything and wipe off the excess.

 

Oven cleaner is cheap and works great too. My theory is there is a lot of water gets up under the hood during driving in the rain.. so all that stuff had better be water proof or these trucks are useless in the rain or snow for that matter..

 

True! Maybe ill just hit it with a water hose and not pressure

 

Purple power is awesome!!! Oven cleaner I would NOT use, Sodium Hydroxide has a tendency to eat metals and pit aluminum badly, it works even better on hot surfaces..... Like an engine with aluminum heads.

 

The last time i washed mine i had water leak down into my spark plug/coil holes and i drove to work the next morning and it was missing like hell. So i just pulled them all out dried and cleaned up the plugs and everything was fine. Thats the only thing stopping me from doing it again.

 

That there is my only fear! Just require
More work to do at least it was nothing bad but there a pain to get to in the first place

 

Cover the alternator. After washing the engine with simple green at 57K, the bearing went out in the alternator.

 

While most have probably gotten away with spraying around at everything its not something you want to direct someone to do...the old...do as i say not as i do thing....

Hate for someone to read "oh yeah spray everything and dont worry about it" and then fry something and be up **** creek.

I like to take a more affectionate approach....a lot of time and a rag an tooth brush or stiff bristle brush and a good cleaner or just some dishsoap an water.

This way you avoid wetting what you dont want wet.

On the armor all thing...i like Tire Wet...think its by black magic...ive used that on lots of plastics and it looks good..i know armor all has certain warnings for use on certain things....

 

I pressure wash mine all the time....but I can see the fuse box as being a weakness for future corrosion, so if you bagged it or don't hit it directly, you should be fine. Just stay back a ways and you won't hit anything very hard, but will work well with a pre soak...

Look at it this way; how do you think all that mud got there in the first place? it was sprayed on! Look under the hood after driving 20 miles in pouring rain...
