I replaced the heater and fan box on the firewall with a new one. I picked this up from Agazza2 when he removed it from his truck to do the HEMTT cab conversion. It must've just been replaced just before it was auctioned because it looks like it just came out of the box.
So I know what you're thinking. Why is Swamp Donkey messing around with the heater in the dead of summer? Well, my old heater core had a seep from the seam where one of the tubes was joined to the core. That tube had gotten bent at some point and partially collapsed the joint. It went unnoticed for a while because there was never the first drip. Over the winter it saturated the floor mat and made a nasty mess.
I picked up a new floor mat from Fuzzytoaster that I plan to install this week. I don't intend to have the same thing happen again and it's no better time to fix the problem then when I don't need it.
A word of advise. If you ever have this box completely out, you'd do well to remove the side and pull the core out of the box. They use some light duty insulating strips to keep the core from moving in the box. Even on the new box, you can shake it and feel the core moving around. I took that foam junk out and replaced it with some dense automotive grade weather stipping to secure it better. Now it's nice and tight and there's no worry of rubbing a hole in the core due to vibration.
I'm on vacation this week, and since it seems nobody else is doing anything to their trucks, I'll bore you with the endless projects and parts swaps I'm catching up on. I got a whole garage full of parts to work with so you've been warned.
Here are a couple of comparison shots. I took some data tag shots for future reference. Note the volt and amp differences.
I also popped in a new coolant filter and checked the coolant PH while I was in there.
More to come...
