SYMPTOMS OF A CLOGGED OR LEAKY HEATER CORE

In this video I explain how you can tell if heater core is clogged or leaking. For example, if the passenger floor mat is soaked in coolant or no heat is coming out of the vent. These are signs of a failing heater core.

What can cause gurgling noise from my heating core.? I got super hot heat. No over heat and no oil in my antifreeze. It started making that noise after a very cold night.

Mine started gurgling and throwing codes recently too. I am going to flush the heater core.

@@PaulHenreid I got mine fix. From replacing the reservoir cap. The seal was too loose. I try purging the cooling system a few times and the noice always come back. The cap replacement did the job.
