The first thing that happens whenever there is a leak in the heater core is coolant comes out through that leak. You can smell a nice fragrance inside your Jeep, which actually comes from the coolant.

The flooring of the passenger compartment will seem to be damp. This is due to the leaking coolant, which can eventually corrode the flooring.

The Cabin Won’t Heat As Expected

The next thing to consider is the heating situation inside your jeep. Jeep Liberty comes with a heating feature that can be controlled through a blend from the driver’s position. However, blower malfunction or blend problems can disrupt this heating feature.

If the above-mentioned causes aren’t present in your Liberty, you need to check the coolant in your engine. If this is also normal, then the heater core defect is the culprit. Mainly, a jammed heater core causes this.

Misty Windows

Probably a terrifying symptom is foggy car windows after turning on the heating. The leak in the heater core lets the antifreeze agent come out as vapor generated by the heat from the core.

The fog, which is the vaporized antifreeze agent, is carcinogenic and can seriously harm the passengers who intake it.

Engine Heating Too Much

The heater core takes heat from the coolant and serves it to the Jeep cabin. Hence, the coolant gets cool in the process. If the process is disturbed, then the coolant doesn’t get to cool down, and the engine overheats due to this. However, you should check the core to be sure.

Hence, if you’re considering a drive knowing this situation, make sure to inspect the coolant frequently.
