The Heater Core Replacement Is Complete!

It took way longer and was more work than just a normal heater core replacement. I wanted to finish the A/C removal a previous owner started and get the defroster working again. Last winter when I was getting the 400 installed I took the A/C box on the outside of the firewall and removed the evaporator from the chamber and cut the box to make it just a heater box. I did the same on the inside part of the unit this time. I removed the blend door that mixed the A/C air and the air that goes through the heater core. Since there is no longer A/C I didn't need the door that went to the under dash duct work. Besides, I have kick panels from a non-A/C car that has dash vents included. The previous owner also pulled the vacuum hoses out of the back of the control head switch. I went online to research pictures and checked on the unit from my parts car. I got the defroster vacuum motor to work properly and the heater works good, too. The only snafu I had was when I pulled the unit out I had to work around the capillary tube for the temp gage and the line for the oil pressure gage, I fractured the oil line. I lost 2 quarts of oil on the way to work today. I need to fix that. I just used a pipe plug to stop the leak until I can fix it properly. Now I carry oil, trans fluid, and antifreeze and some basic tools in the trunk along with my detailing kit. I'm glad I was the one that put this car together and "in tune" with what it tells me.
