Where is the thermostat on a 2006 Uplander?

Where is the heater core on a 2006 Chevy Uplander?

The heater core looks like a very small radiator, and functions just the same. It’s mounted under the dashboard, and it provides the heat needed for the blower motor to warm the cabin.

Does coolant have anything to do with heat?

Radiator fluid runs through the engine and becomes hot. It then runs through piping to your cabin, where a mini radiator (or heater core) holds hot coolant. A fan blows over your heater core and directs warm air into the cabin. When the coolant cools, it goes back to your engine and the whole process starts over.

Can low engine coolant cause heater not work?

If the coolant level is low, the core isn’t working, or there’s air in the system, your car’s heater may not work. The coolant itself could also be an issue. If there are rust particles or other contaminants in the coolant, it could prevent the heating core from distributing heated air into the cabin.
