The heater control valve in a Mustang is located within the engine. It is right in the heater's core and where the coolant is located.
The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
In the radiator, coolant recover tank, heater core, and inside the engine water jacket.
If your heater core is LEAKING engine coolant so that your engine coolant level drops too low or the engine coolant is lost completely and causes your engine to overheat then your engine can be damaged beside the mess the leaking coolant makes inside your vehicle ( you might be able to just temporarily bypass the heater core so that no engine coolant is flowing through the heater core )
Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.
The outlet from the engine that feeds hot coolant into the heater core is usually (but not always) located close to the thermostat. The return hose from the heater core usually returns into the water pump.
The coolant temp sensor screws into the side of the engine. It is located just below the connectors for the heater hoses.
Check the radiator for full coolant. Check the engines water pump and thermostat, as the engine coolant carries heat from the engine into the heater core.
No , this coolant is coming from your heater core and you are losing engine coolant ; you need to have this repaired because the engine will overheat and suffer damage that will be more expensive than the repair of the heater core .
heater core has a leak replace heater core
The heater core has gone bad if there is coolant in the interior of the vehicle. The heater core is a small radiator that is located in the dash board. It radiates heat from the engine coolant into the interior of the vehicle.
