Best Practices

We recommend using a high-quality replacement heater core. Cheap heater cores tend to leak and not last very long.

The heater hoses should be inspected when replacing a heater core. Problems with the heater hoses can cause similar problems to a failing heater core and are less expensive to correct.

Common Symptoms

A failed Chevrolet Blazer heater core can result in the car windows fogging up, coolant leaking under the dashboard, a sweet smell inside the vehicle, and mystery coolant loss.

Worn engine mounts allow the engine to move more than normal, which can damage heater core connections. Worn mounts should be replaced to avoid damage to the new heater hoses.
