We have an Isuzu Rodeo. It has been overheating but not to the point that it smokes. The needle just starts going up. We turn the heater on and the gauge goes down. We have replaced the thermostat twice replace all th hoses, the water pump, the timing belt, and other belts, new fan clutch and it still is over heating. It is an older car but it only has this probem

Try bleeding the cooling system that don't work get it block or pressure tested-

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.
