Having problems with your 2000 Pontiac Montana ?

I have a Pontiac Montana (2000). That on my way to work the low coolant level light came on. and after work when I started it up the light did not come right away but it came on and there was no heat and the temp guage went up. Could this be the thermastat? And where would it be located??

Answers :

No. It is not the thermostat. You are just low on coolant. The reason for the low coolant is either the fan is not working, the head gasket is blown, or the coolant system has a leak.
The fan is easy to check. When the temp comes up then the fan should come on.
The head gasket is easy to check also. Your oil will be milky white.
And if the radiator, radiator hose, or gasket leak can be harder to find.
The heater not working is because there is not enough water to heat the heater core.
PLEASE RATE. By checking Four thumbs ups!
Thanks! Have a GREAT DAY!
If the coolant level in the unit is filled, the vehicle is not running hot, or there is no milky substance (for example, coolant leaking from the engine head gaskets into the oil), you might suspect the Coolant Level Indicator Sensor (either in the coolant container or along side the radiator (about $50-75 part).
