I'm just finishing up a mounting bracket for the FMOC and was wondering what is the best way of cleaning up the cooler? I'm hooking up stainless steel lines with earl fittings and right now, the cooler will be the only grundgy looking thing in there. Can you paint the cooler? If so, what's recommended?

 

Wouldn't recommend painting the cooler, as it would hold the heat in a little more. There is a company based in Texas that does fin straightening and a thermo-paint job that cools it better than other paints. Search the 3rd gen section for it.

Other than that, elbow grease and engine degreaser/brake cleaner worked for me.

 

Take it to a Radiator shop. They can clean it, inside and out, and recoat it. Preferably one with a good reputation with your local stock car racers. Also flush it with some oil when you get it back, alum can collect condensation inside.

 

Just go to a HVACR parts house and buy the tool. Its not that expensive. Thats what I use on OC as well as radiator. The fins are there to route more air to the coils.

 

What kind of coin are we talking?

 

tubes in the OC.

 

Mazdatrix used to offer sonic cleaning, which is apparently how the aero industry cleans their oil coolers. Sent mine to
