I have an 89 GT with minor mods (exhaust, 65mmThrottle Body, 70mm Mass Air Meter, and the usual suspension upgrades)and the car runs hot. Its running around 235 w/AC on, (thats in between the N and O on the gauge, pretty high on the gauge) and I have replaced the fliud, flushed the system, bypassed the heater, changed thermostat, and even got another water pump. My next purchase will be a radiator if I can not get a fix here. Its an expensive piece so i wanted some help before I did it. Anyone got a fix. Also ever have a problem where your starter gets stuck, this just started happening?
