Kooler Kleen?

That is about all I know of. Then you follow it up with air. Then maybe run some oil through it. Run it into a fine strainer and make sure no significant debris comes out.

 

Flush it out with petrol to clean then dry it then put some oil through it..

 

Running 9b's warzone?

 

For now.

got some for really cheap, rebuilt and ported them. I also ported them front manifold the best i could.

 

Seafoam?

 

First thing I did when I bought my '97 was to visit the local Mitsubishi dealer to have it Power Flushed. The person that did the work became a very good friend of mine...Ray Pampena

 

awwwwww

 

Just flushed my cooler on a whim, started thinking about how important it is to get new turbo oil lines after spinning a bearing, but hardly anyone mentions the oil cooler. I blew it out with air first. A bunch of greenish oil/fuel/coolant stuff came out. I then pumped clean oil into the oil cooler and blew that out with air about 3x until it was clear.

 

My method isn't for everyone, as everyone doesn't have a solvent parts washer. I hook the brush hose directly to the cooler and let it flush for a considerable amount of time. I also reverse the flow several times, and tap the entire surface with a large plastic screwdriver handle do break loose any debris. I follow up by blowing it out with air.

 

I took mine to a radiator shop and they soaked it in hot hot water and then they power flushed with even hotter water for about 30 min straight.
