the fans are deffenetly pulling air threw my radiator. I have them mounted inside the engine bay and they pull 1,800 CFM per fan threw may rad, It blows you hair back standing by one of my fenders lol. Maybe the water pump is Shitty? or is it one of those situations were its either crap or not crap with no inbetween. I should really invest in a aftermarket rad and a nismo therm. I always seem to loose rad fluid also, but to my knowladge my radiator is not leaking. it happens when i dog on the car, I park is and like I noticed one time that I had a puddle of water under my car when I drove away later. In general it looses water some how also, but when parked on a hill and filled properly it still stays at 190-210 degrese. Sorry, really stupid problem, million situations for a fix. heating issues on a car really blow because theirs like a thousand senarios.
