How long should a new heater core last?

That number is all over the board depending on how the coolant has been maintained, whether the core is grounded or not, and the quality of the core. I’d expect 5-7 years would be on the short end; I just replaced the original heater core in mine after 21 years of service.

What can cause a heater core to go bad?

There are multiple reasons a car’s heater core could not be working properly. One reason could be due to clogging, as the coolant could become contaminated if it’s not regularly flushed out. Another reason for a bad heater core could be because of a leak somewhere in the system.

Do heater cores wear out?

A heater core often goes bad due to leaking. As the heater core uses engine coolant to generate heat, a leaking heater core will reduce the amount of coolant in the cooling system. Low coolant will cause an engine to run at a higher temperature, which can result in extensive engine damage.

How is a heater core different from a radiator?

While the radiator transfers heat from the hot coolant into the atmosphere, the heater core transfers heat to the cabin. Like your car’s radiator, the heater core is a heat exchanger. But while the radiator transfers heat from the hot coolant into the atmosphere, the heater core transfers heat to the cabin.

What happens when there is no coolant in the heater?

Room-temperature air occurs when there’s little or no coolant flowing through the heater core, which is usually the result of a leaking heater core. The blower motor will still force air into your car’s cabin, but without hot coolant flowing through the heater core, it won’t produce hot air.
