What is the Heater Core?

The heater core looks very similar to a mini-version of your car’s radiator, and in fact is in itself a small radiator. It has a grid of several little tubes as well as a waffled appearance that comes from the fins that are used in dispersing the heat.

A clog in the heater core forms as a result of the residue deposits left behind by old coolant. This will eventually end up sealing up the core tubes through which the coolant is meant to flow. Regularly flushing the car’s coolant system assists in preventing this type of clogging in the heater core.

Depending on the size of the hole, a leaking core could still be supplying some level of heat. You may identify a leaking heater core by the smell of coolant emanating from the vents or the wet patches visible on the rug of your car, especially on the passenger side.
