Ok. So i'm putting my 88N/A back together and I plan on cleaning the Oil cooler.. I just got the 7 a few months ago and it looks like the oil cooler hasnt been cleaned since the thing was rolled off the assembly line.. I was wondering what is the best way to clean an oil cooler with about 20 years of build-up aside from pressure washing it... I dont believe i have access to a pressure washer so what's the best way to clean it without pressure washing it...

and also, say if i can get my hands on a pressure washer, should i just use straight water? or what?

 

the way we clean radiators and oil coolers and the such at work is we spray them a degreaser, let them soak for about 10 minutes and then pressure wash them. We also use TONS of Carb cleaner for all parts. Be sure to spray directly on the front or back as to not bend the fins.

 

Ok... I'm going to go pick up a case of degreaser tomorrow. Thanks

 

I'd go to walmart and buy a can of engine de-greaser, then I would spray that **** on there and let it soak in for a little bit. After that, I would go to town on it with a big nylon brush. Lastly I would put it in a garbage bag and haul it to the nearest U wash it car wash and blast any remaining crap off of it with pressurized water.

 

go to a machine shop and have them boil it (i believe that is the term).... it removes all the old paint and even the crap on the inside which is what you should be worrying about! just remember that oil coolers work just like an oil filter, they catch all kinds of **** in them and eventually it will come out.... into your engine that is

 

if u want to take it a step further u can rinse it with carb cleaner to get any residue left over
