First and foremost, I'm not trying to steal anyone's thunder or document step by step how to do this. As a matter of fact, I'm giving all the props to rixcj for posting this "how to" (http://www.jeepforum.com/forum/f8/cj...-heavy-975999/
). This is the thread that I used to upgrade mine as it was very informative. It should be a sticky on doing this upgrade.
Since I already had my dash off, I decided to do this as it would be easier without all that mess in my way. I'm getting ready to order a new dash from Double D Fabrication and install new Auto Meter gauges. This is a good time for this upgrade.
I took out the computer. This thing is super dirty.
The computer was a mess and had 25+ years of oil and grime on it. Most of that junk on it is oil. I do not know where that came from. I did not see any lines or leak around this area. Weird.
I pulled the heater hoses off and drained what anti-freeze that I could. I also bought new heater hoses and a new core from NAPA. Those will be going in as well. Also, there are four bolts that hold the heater assembly to the firewall. Three are super easy to find and remove (inside the yellow circles).
The fourth one took some searching. I've been frustrated before, but not like this in a long while. The last bolt is hiding behind the valve cover on my 258. I thought I would NEVER get that last nut removed!
Once it was gone, the whole heater assembly came right out. This thing is filthy, but I've seen a lot worse. It should clean up nicely.
The heater motor is obviously caked with years of dirt and grime. I'll be glad to get the new one installed.
Some jackwagon had crimped one side of the outtake hose. It's no wonder I wasn't getting the proper amount of heat from the heater.
