Did my JDM SR20DE swap and having problems with the radiator fans coming on. They work cause i tested the sensor with a lighter and the fans come on the problem is i think there is air in the system so the sensor isn't getting a reading for the coolant mix. So my question is , Where the hell is the rear bleeder screw on my car. The 93 and Below G20's have it near the fire wall as for my 93.5 its not there. I think i got the shaft when it came to choosing the year of my car. Anyways on the newer version 94 and up i asumming where the hell is the rear bleeder?
