LOCATION OF THE THERMOSTAT

1999 Oldsmobile Alero

Heater problem
1999 Oldsmobile Alero 6 cyl Front Wheel Drive Automatic 142000 miles

Hi. Where exactly is the location of the thermostat on a 1999 Alero Oldsmobile 6 cylinder? And is it possible for a defective thermostat to cause the heater to not get hot? The car only gets hot when driving at a high rate of speed. Thanks for all you do Chris

Unbolt thermo is there. When refilling open the bleeder on neck of housing to expell air.
Hope this helps

Thanks for the reply. However, the diagram is somewhat hard to understand. Which is the back of the engine and still can't follow exactly where the thermostat is located. Could you be a little more specific. Thanks
