I replaced everything on my AC system but the evaporator plus I installed a valve in the heater hose that runs under the throttle body but when I close it my car runs a little hotter does anyone have any suggestions on where to put it.I put them on every Gm vehicle I buy and it really helps the AC get cooler.
