Stock 70 mav I6 200, New water pump, 160 thermostat, Chinese ebay aluminum radiator, stant rad cap, overflow tank, stock fan w/o shroud, no AC, timing set to factory specs. The car is a daily driver, 30 miles to and from work, usually around 70 mph on the freeway. The car usually runs a constant 160 degrees. last few days the weather has been is the 100-110 range and the car started overheating on the open freeway. The car seems to slowly cool down once I jump off the freeway and hit surface streets. It also drops to 160 if I spray the rad w/water Not sure if this is the norm for an older maverick or if I can do anything to help keep it running cooler.
