Overheating Still. Need Help

Discussion in '1994 - 1995 Specific Tech' started by GrapeApe318, Sep 9, 2013.

  1. A couple of months ago I posted about some issues where my 95 GT would get hot with the A/C on and it was in fact a head gasket. I put brand new head gaskets and had heads resurfaced ($300.00) and had my all aluminum Mishimoto 3 core radiator pressure tested and was told it leaked. I spent $650 on a new Mishimoto all aluminum 3 core radiator and brand new Silicon hoses along with a new Aluminum fan shroud and a 15 inch Mishimoto fan. I also wrapped my headers to help keep the heat out from under the hood. Well I live in Louisiana and its 100 degrees around here this time of year so when I kick on my AC, the temp will get up from 180 and gradually climb to 220+ . If I turn the AC off the temp stays put but if I turn heater on full blast it slowly drops the temp. Any ideas as to what I can try to reduce the temp? I have the fan hooked up to a relay off the ignition switch and it is blowing full speed. The water pump is a high flow I got off summit and the pulley is rotating counter clockwise. Im not sure what else it could be. Possibly need a smaller pulley or an oil cooler? Im stroked to 331 and running 10 si on a Vortec V2 S-trim.

  2. Not that it matters but I just noticed I need to update some info on my vehicle description. Main thing is I got rid of those crappy BF Goodrich G- Force and now have Nitto NT 555R's
  3. When you're car overheated w ac on did steam come out from behind the back of the lower intake area w white smoke out the tails? I got my ac fixed not tool ago ( on the 95) and when I went down the road w the ac on it started running rough and overheating. A lil white smoke or possibly steam I dunno came out the tail and steam was coming out the back of the engine around the lower intake or possibly head. Man I hope it's not the head gasket. I think a bad idler pulley was the catalyst but I'm not sure. I'm hoping for blown lower intake gasket
