Engine Cooling problem
1996 Chevy Lumina 6 cyl Front Wheel Drive Automatic 170000 miles
1996 Chevy Lumina 3.1 cooling system overheating. Some days I can drive 50 miles before overheating and then other days I can't go 5 miles before overheating. The temperature exceeds 220 degrees. The upper radiator hose is extremely hot to the touch although the lower hose not as hot. The radiator boils over and fills the coolant recovery tank and as it cools the tank replaces the coolant in the radiator. After the engine has cooled down I tried to add coolant with the engine running through the fill tube of the radiator. The system spits and pours more coolant out of the fill tube than I can put in. I have the bleeder screw open to release any air that may be in the system. Over the past 6 months I have replaced the heater core, water pump, and thermostat. I removed the radiator and had it tested and cleaned. Both fans are in good working order. Any suggestions as to what I can do to eliminate this overheating problem. Thank You!
have the same problem?
