Where is the heater core on a 92 Ford Tempo?

Answer 1

The heater core is above/behind the air outlet for the floor. The heater core can be tricky to get out and take a bit of time and patience. Be sure it's the heater core before you take on this task. It will save you a lot of frustration. If your car gets hot but you still blow cold air when temp setting is in hot then you have either low coolant, a stuck thermostat, or a blocked heater core. If your interior floor is damp near the center front of the floor, then you most likely have a leaky heater core.
