Intercooler cleaning and prep.
 

Sorry Mods about the Cross Post, but there's more traffic here!

Allright, I was going to use my beautful small Isuzu NPR Intercooler for my Turbo Project.

I got a pretty good deal on the Large Black Isuzu NPR intercooler. It is the best out of all the NPR IC's, so I definately want to use it.

It's in good condition, except some of the paint is chipping off, making it look worse than it is.

So my questions are:

1) How do I properly strip the paint without damaging it?
2) Could a Radiator shop strip and prep it?
3) Or does it have to be an Intercooler repair type of place?

My goal would be to have it shine like small polished one above.

Before you ask, - I am not selling the small NPR at this time, I am probably going to use it in Supercharging my Ford Supercrew

Just get some paint stripper that won't destroy or etch that alum. I am assuming that is the ic it is made of. Maybe an aircraft stripper. Most airplanes are alum.

You can run kerosen through it. Then simple grean through it to clean out the fuel.

Don't paint it though. It seems that would cut down on efficancy.

Just an educated thought.

How thick is the core and how much did you pay for it?

Painting won't affect its efficiency, unless it's in sunlight or something like. It's too late for me to get into this. Aircraft stripper would do it. So can a radiator place.

Huh? Why not? If you paint the IC and the paint gets between the fins, you're not getting air flow between them and thus no cooling? Correct me if I'm wrong...

But to clean the inside, I normally use gasoline. Poor it in the inside, shake it up REAL good and dump it on an innocent smoking by-standard...:D

They can be painted, but it's best to use the spray paint you use to paint your trim. It's a little thinner

Eastwood makes a black paint specifically for radiators. Its ultra thin so as not to decrease efficiency.
