Question about 2001 Pontiac Sunfire

2001 Pontiac Sunfire 2.2 L overheating / runs out of antifreeze

My 2001 pontiac over heats when the heat is on. The needle starts to rise, i turn heat off, it goes back down. The "add coollant" light keeps coming on. I add collant - 50/50 mix then its ok for a little while, lately just a day or two then bam! same thing again. I'm planning on a flush, as this has staved off the problem in the past. I've also tried putting a different ratio of anti-freeze, less water. I use the reccomemded kind and all that. I don't think I'm leaking coolant. Also my oil is not milky

It could be one of three things: drive belt, water pump or thermastat when you take in for the flush have all of these checked out

2004 Pontiac Grand Am 6cycl 3.4L, overheating issues.


Sounds like you had a sticking thermostat when you replaced the waterpump causing an air pocket. Replace the thermostat, and jack the front of the car so that the radiator cap is highest part of the cooling system. Then run the car and burp the air out of the coolant system.

Pontiac sunfire overheating


hello! I had the same problem with my 2000 Pontiac Sunfire... there might be one of these 2 problems with it.... maybe the Heater Core is jammed and the coolant dosen't flow thru the engine to cool it off, or the water pump is defective.... does the heating works or not? if yes, the water pump is defect, if not, the heater core is jammed, try a ''radiator hose cleaner'' (sold in Napa's or Carquest..) it will act as a kind of ''decloaker''.. if works, good! 15$ solution... if not, replace Heater Core... ~150$

1997-98 sunfire 2-2 liter changed thermostad and changed heater core still no heat. half and half mixture of antifreeze put in what else can i do car is running normal no overheating


First of all, make sure the heater core isn't air locked. With the engine running, and your heat temperature on high, loosen one end of the heater hose and see if you can get the air out of it.

Where to refill a flushed radiator on 1996 pontiac sunfire


If there is no radiator cap on the radiator, that would indicate to me that the procedure for flushing and re-filling is done with the motor running, and the heat on high. Filling is done by pouring antifreeze into the coolant reservoir.

Have a 95 Pontiac Sunfire. Bought car with blown headgasket (replaced) in the process aqua locked an injector (replaced) and also replaced the thermostat. Currently have cooling far wired to a Toggle...


Keep it simple, try flushing out the cooling system with Preston radiator flush, just follow the instruction on the bottle and replace the coolant with a 50/50 mix. Note that the orange antifreeze are know to crystallize if the concentration is to high and will plug up the water jackets and radiator so a good radiator flush will fix the poor circulation problem, also try to keep the coolant to a 50/50 mix, to much antifreeze will gel up when heated and to much water will boil over.  As for the temperature sensor, it's not that expensive and can be replaced with simple tools, also check the wire harness to ensure that there are no damages or corrosion that would cause a false reading.

2001 pontiac montana overheating no warm air when heat is on


Might be a weak or failing water pump... Does it leak antifreeze or do you have to add antifreeze very often? When the engine gets to operating temperature squeeze the top radiator hose and see if you can feel pressure from the water pump forcing water through it.
