Re: Radiator fan help..electrical aspect

the intercooler could be cracked or I've also seen people talk about it leaking at the o-rings where the lines go to the intercooler core itself. Id definitely check on it though, you dont want the lower intake to fill up to the point you end up with water in the cylinders

I bought Mityvac MV4560 Radiator/Cooling System and Pressure Test Kit on Amazon for like $45. Ive been using that to test my cooling systems. I'll be honest its kind of a pain in the *** to sit there and squeeze that handle a million times to get up to 15psi but it does work. When I was looking a couple years ago all the better options were a lot more money.
