Temperature hot or not?
Hello I have a 99 Alero 3.4L with 189,000km and I currently just changed my water pump and bleed the system. But my temperture seems to creep up to half way between half and 3/4 when idling in traffic even and drops down to 3/4 between 1/4 and 1/2 marks when driving (normal from when i bought it) its been about 0 celcius here when its been doing this. Now i was wondering what could possibly be causing this and also i have noticed that I have not seen my rad fans kicking in even when its idling and the temp is between 1/2 and 3/4 is this normal? and what is the approx tempertaure the car is reading at these markers....

Re: Temperature hot or not?
I would say your fan is not working , could be the sensor or the fan motor. start with checking the wire to the fan

Disconnect the electrical connector to the engine coolant temperature sensor (ECT) located by the thermostat area and start engine. Both fans should turn on after about a 5 second delay in fail safe mode. Also, how old is your thermostat? Around half or a tick below on the temperature gauge should represent around 195 degrees F which is the regulating temperature of the thermostat, if stock.

Re: Temperature hot or not?
So after some researching around i found the ECT and i disconnected the electrical connector for it and both fans kicked in as you said approximating 5 seconds later, with that tested now where does that narrow my problem down too? thanks again for the help so far. (and for the fantastic site I have gotten alot of other help for )
