Well, I replaced my radiator yesterday along with a 180 thermostat. (It has to be one of the easiast things to change on this car). Is that the temp everyone suggests? The car (91gt) is running alot cooler now. It just gets to the n in normal or a little past on the gauge now. with the 195 it was running on the r to m range. Just wish I would have had the header to put on while the radiator was out. It gives you quite a bit more room to work. but the money for the header replaced my radiator. Hopefully the exhaust system will be next.
