Heater Core Failure Signs and symptoms

All vehicle heating systems apply heater cores, which are coincidental to limited radiators in shape and assistance, to perform basic heater transaction operations. Heater core failure can engender a diversity of heater-related problems and symptoms. A failed heater core loses its intelligence to convert heated.

Leaky Heater Core

It's commonplace for a failed heater core to progress cracks in its core and/or heater hose connections, cracks that can concede circulating engine coolant to leak elsewhere into surrounding areas, including into a vehicle's interior and/or engine compartment.

Erratic Heater Function



What follows is a miniature information of the most everyday symptoms of a failed heater core.

Cold Heater Output

A vehicle heater that fails to build heat after a sufficient vehicle warm-up interval is usually a note of heater core failure. A heater core is designed to cause heat as soon as circulating engine coolant becomes Enough heated by engine heat.





A heater transaction that functions erratically---going from flaming to below zero and back again continually---is ofttimes a note of a failed heater core. As a heater core fails, it starts to lose increasingly of its heater core integrity, which results in erratic heater function.


Slow Heater Warm Up


Normally, a heater will start to produce heat after a vehicle has been idling for a few minutes. A vehicle heater that takes an abnormal amount of time to warm up---10 minutes or so---is often a sign of a heater system that has a failed heater core. As a heater core fails, it loses its ability to operate normally.


Heater Core Noise


A well-functioning heater and heater core assembly should be virtually noise free when in operation. A failed (or failing) heater core assembly often times makes noise---grinding, swooshing or clanking sounds---especially right after vehicle start up and/or heater activation.
