How do I..........?

[MUDRAT]

What do i use to clean out the black crap out of my intercooler??

[Dave-H]

A de-greaser [Jizer, Gunk, etc]
Then flush it clean with water and make sure the innards are completely dry before refitting.

I wash mine out with gizer type degreaser then rinse it out with petrol.
