2005 Buick Century Question: My heat doesn't get as hot as it used to.



mdubose22, 3.1L V6, Cincinnati, OH, January 23, 2013, 15:32

My car warms up very slowly and never gets hot inside like it used to. Both of the ac/heat cluster lights are out and the temperature gauge always leans towards the cold side. Also, after a quick scan concerning my check engine light, the code had something to do with a thermostat.

    The thermostat may be stuck open not allowing the cooling system to get hot as it should. I would say you have a stuck open thermostate. It's a cheap fix about $30 in aftermarket parts. You will need the thermostat, thermostat gasket and a gallon of coolant 50/50 mix dexcool.
