Question about 2000 Oldsmobile Silhouette
If your coolant is low, the heater core is the last place to get the hot coolant. If so, fill the system and check for leaks. If you have a 3.1 GM motor, check the intake manifold gasket.
Thermostat is stuck.
Heater core is plugged -- when the car is hot, grab the hose going to the heater core and the one coming out, they should both be hot. If one isn't, try back flushing.
Remove the two hoses to the heater core, push water through the outlet hose into the heater core. You can eliminate the heater core however by running the engine until it is up to temperature. Feel the hose going into the heater core- is it hot?-should be. Now feel the outlet hose of the heater core- is it hot? it should feel about the same. If the outlet is cold and inlet is hot, you know the heater core is plugged. you can do the same on a radiator to see if it has good flow.
Hope this helps and have a great day!
