Question about 2005 Chevrolet Impala
I changed the thermostat and the temp gauge still goes up and up and the heater is blowing nothing but cold air?
Does it blow warm air when you drive the car? If so its the water pump.
Could also be air in the coolant system
Also have the cylinder head pressure tested to rule out a hblown head gasket
Hope this helps

sounds like you have a bad temperature sensor in dash or the cable has eitehr broken or come off the heater switch under the dash!!

Sounds like the thermostat needs to be replaced. If you do the work yourself be sure the temp threshold is correct and the flow direction is correct when installed. Good luck to you

Probably. Is the coolant level ok? If yes, then change the t'stat, sounds like it's opening and closing randomly, may be defective.
