Question about 1999 Buick Century
Where is the thermostat located on the motor of a 2003 buick century. A water pump was just put on now the heater is blowing out warm or cold air.
Fllow top radiator hose from radiator to engine, where hose clamps on engine is called a goose neck thermostat is under that, it will be held on with 2 bolts. are you sure you got all the air out of system when you chg. water pump? If you don't bleed all air out of system it will not blow hot, because of an air pocket in cooling system.
