Question about 2003 Pontiac Montana

Possible overheating, 2004 pontiac montana

Not an everyday occurance, but sometimes temp gauge runs into the red within 5min of driving. radiator cap is not hot when this happens. most times vehicle can sit less than 5min, start again and read normal. coolant level is full. twice have drivrn short distances with gauge showing in the red but no idiot lights ever came on and vehicle ran as normal. does this sound like the vehicle is really over heating or could this be a false reading?

Its definitly a bad reading, you would know if your vehicle is overheating, you can usually smell it right away.I would say its your temperature gauge sending unit is defective, check the wires to see if they are well connected or broken. ask a backyard mechanic for assistance.

Cooling problems can be hard to pin down.

Do you know if your electric engine fan comes on? If not they should, if you had the radiator fixed how was it done, new, rebuilt, or some fix a leak in a can? Driving an over heating car will ruin it, while the car is off and has sat long enough for the engine to cool, remove the radiator cap and check the fluid, do you have enough?

If the radiator was removed and replaced something may have worked it's way loose as in a wiring harness that runs the fans, most fans have a plastic safety pin of sorts that keep the fan harness from unplugging.

Another problem may be your water pump, since it's taken a month for you to notice any problem with the car I would not think it needs to be bled. Tho it might need to be.

Take the car to your local garage and have them look at it, if you dont do anything your cars engine can become damaged.

I do hope this helps!

Temp gauge goes into the red while driving then back down to normal levels. Pulled over and checked the coolant level. Overflow was half full and the radiator cap was cool to the touch.


your thermostat is not opening there for not allowing hot coolant to exchange into the radiator. replace thermostat.also causing you to overheat

Check your cooling fan motor at radiator, should come on at about 220 -225 deg, while moving you have air blowing through radiator and will keep engine cool, at stops no air going through radiator and will cause over heating. Have fan check out

A red light with a circle and 3 small peaks within the circle come on, what does this mean?


Probably coolant temp light. When vehicle has cooled overnight, check the coolant level in the radiator. Very difficult to open radiator cap on this vehicle, because engine brace is in they way. You don't want to keep driving with this light on on, could do damage to engine.

Low coolant temp light


STOP DRIVING!!!!.... if you have no coolant in the system you can ruin your engine.... if there is coolant inside the cabin then it is your heater core that is leaking.... it is difficult ot change on some vehicles becuase it is in the dash but still possible for the backyard mechanic.... you should be able to find one for about $100 but there is alot of labour involved...

Heating problem


Yes that is cool if it's correct. 195 F is approx.as low as you should have. I'd change it. Be sure to run with cap off, and heater on (not defrost) while refilling system. Wait for rad fan to come on 2 or 3 times before you put cap back on, then add coolant to return bottle as needed. Make sure rad fan only comes on when up to normal running temperature. If it runs all the time, it may be causing low coolant temperature too.
