I bought a used 7.3 intercooler and it looks like there is some dirt in it, what is a good way to clean it out? Thanks.

 

Dawn dishwashing soap or simple green, either one will remove the oily residue.

 

So dump some dish soap and then flush with a garden hose? Is that enough flow to flush it well? Maybe block off one end to let it fill up then open it to let it rush out.

 

Soak it in a bucket of simple green or super clean.

super clean you can mix with water and still make a good solution
make sure you buy the grease type super clean, there are others that wont work.

If you use dish soap, use hot water and a bucket, and soak it.

agitate any of these every 5 or 10 mins.

 

I don't think I have anything that big to I could submerg the intercooler in. I may have to rig something up plastic. Thank you the tip.

 

use a garbage can

 

Intercoolers are pretty wide, I don't think it would fit in a 55 gallon drum. I wonder if a radiator shop would steam clean it. That should flush out the crap shouldn't it?

 

Get a plastic child's swimming pool, fill with water and simple green, when done with the intercooler then the whole family including the dog can jump in and take a bath.

I already have my 4x18' pool up, but that might cost too much for the amount of simple green I would need.

 

I was thinking the same question. I was just gonna fill it with carb cleaner and shake it around for a while. Do that probably twice, then air dry....no pun intended.

 

I think I am going to call a radiator shop today and see if they can flush it. If they can they should be able to get it cleaner then I could. Rather no take a chance of haveing dirt, or whatever else may be in there, going into the engine.

 

I had the local radiator shop flush it, a little pricy at $40 I think, but maybe a small price to pay to be sure no dirt gets circulated through the cylinders.
