Just replaced my thermostat, the gauge went up one querter of the way. Heat is ok, but could be better. This is the third one I installed so I know its not bad. It takes way to long to warm up. I remember the gauge going up to half way when I bought the car?
bradz...you need to check the opening temp of your installed thermostat its usually on the thermostat body....the one you have now could be a lower opening temp which is whats causing your Z to run somewhat cooler considering you dont have any mods and dependin on what stock your auto parts store carries...i hope this helps
