[quote:575ce339cb="fordman363"]My girlfriends 1994 Jeep Cherokee started running a little on the hot side. So i decided to the flush the radiator out due to being a nasty brown color. In return it wanted to overheat even more in very little time. So i replaced the thermostat and the water pump and neither fixed the problem. Is it a bad radiator? What else could it be?[/quote:575ce339cb]
Sir
Did you bleed the cooling system? if not try below-don't work wiil take it to the extreme
Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.
