I am having a hella of a tough time purging my intercooler system. Last 2 times the suck the return hose off the reservoir did the trick, but I have tried about 3 times and have had no luck. I feel the hose going to the top of the HE flowing with water but not the hose coming out the HE. I also tried while on incline but no luck. My assumption is that the aftercooler itself is full of air. I have heard using a garden hose does the trick. Anyone have any details on this???? Of the two lines going to the aftercooler which hose is return/feed?????? Thanx in advance, this sucks not being able to go into boost!!!!
