Jeep Grand Cherokee WJ – Heater Core Replacement
May 13, 2012Posted by on
Well It’s been a year already since I bought Mr. Jeep. He’s been a fine companion. I’ve pulled a couple of trailers, driven it to work on occasion, and even done some off road adventures! Since I bought it, I noticed that when I put the heat on, I can smell a little bit of anti-freeze. At first I thought that maybe it was my imagination, but when others commented on the smell, I knew it wasn’t just me. One friends said, “I smell maple syrup!” when I turned on the heat. I knew I had to take care of this issue. So I pulled out the Haynes manual one day to see where the heater core was located, thinking that I would have to remove a panel on the passenger side. I wanted to give the core and that area a look-over for any signs of leakage. What I discovered in the Haynes manual is that it’s a triathlon to change out the core. So i held off for a while, but I was concerned that the small leak could get much worse of the core could just burst and that would be bad. If you have one of these WJ’s and you need to replace the heater core, the AC evaporator, or fix the heat blend doors, you will need to remove the dashboard.

Below are some pictures I took while tackling this project, along with some brief descriptions.
