I have a 1987 automatic 2wd deville with about 70K on it. Recently, the radiator blew and I replaced it. The car is running hot suddently after about 100miles and there is a froth at the top of the coolant, also my heater doesn't run when it used to for some strange reason.

I am waiting for ANY responses.

Could be air inside bleed it thoroughly follow below and then comeback

BLEEDING COOLING SYSTEM

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.

You see were nice people well here it is go apply it
