Heater cores are usually well protected from mechanical damage but they can be damaged by corrosion and sediment deposits. If you change the coolant in accordance with the manufacturer's recommendations you will extend the life of the heater core, the water pump and the radiator.

Your heater is powered by your heater core. Your engine coolant runs through your engine gets hot, runs through the core heats the air, then back out to radiator. You probably need to replace your heater core.
Why do you smell antifreeze in the cab of your Subaru?
Antifreeze is used to heat the cab of your vehicle. When you turn on your heat in your cab, it opens up a valve that allows the hot antifreeze to flow from the radiator into the heater core. If there is a leak in the rubber tubes that flow into the heater core, or if the heatercore is damaged, you will smell the antifreeze in the cab of the vehicle. You may need new hoses to the heater core and/or a new heater core.

Where is the heater core on a 92 Ford Tempo?
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.
If the heater core is not replaced can it cause damage?
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 )
Can the heater core on a Cavalier be bypassed?
yes it can, but dont really recommend it. if your car starts to over heat and the heater core not there you can not use the heater fan to help cool it down, also if you live in an area where it gets cold you wont have no heat.
