Having problems with your 2005 Chevrolet Impala ?

Heater blowing cold both sides

\015 I changed the thermostat and the temp gauge still goes up and up and the heater is blowing nothing but cold air?\015 Posted / edited by AnonymousUser on : 08-08-2022

Answers :

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
