#acbox

Heater unit is in and all cables are hooked and work. Had a few issues along the way getting it back in. This is the second time I've had to take it out and put it back in since owning the car. Never have liked underdash work as it always seems to be a pain. I have a couple of things to pick up and it should be getting wrapped up sometime tomorrow if, and the key is if all goes well. Still have some wiring to do on the heater unit. Getting closer. #designsbyandrew #bella #64belair #restoration #xframe #bbody #chevroletbelair #chevrolet #car #cars #60smuscle #realmetal #landyachtz #ironsides #heaterbox #acbox

Part 1 of 2 slide shows. I have been modifying my old factory ac evaporator case to use a newer evaporator out of a 96 Nissan Sentra. The old evaporator had the lines busted off before I purchased the car and being the car was from Phoenix originally, I'm was sure it had tons of sand inside even if it might be salvageable. It turned out it wasn't salvageable as I found dirt build up in one corner where the ac system oil had leaked out. There was tons of corrosion on the core itself so rather than deal with buying another stock evaporator and throttling valve, I opted to go with a late model evaporator that utilizes the R134 with a expansion valve assembly. I had to make modifications to the fiberglass case for the tubes to exit the case along with block off plates for holes in the case not used. Part 2 will show the modifications done to make it work. #designsbyandrew #bella #64belair #restoration #xframe #bbody #chevroletbelair #chevrolet #car #cars #60smuscle #realmetal #landyachtz #ironsides #acbox #acevaporator #evaporator #custommodifications #custommade #automotiveac

I encountered a problem with the information that I found on the internet about using a heater ac unit out of a 88 to 92 civic and Integra for my 64 Bel Air. Due to the imports along with just about every car built now, the heater box assembly is too tall to fit under the dash of the 64. The 64 has a transmission tunnel due to being rear wheel drive which is one of the many problems. The newer vehicles tend to have a flat firewall and concentrate most of the heater box in the center of the car behind the dash. So as they say the internet is 90% bs, it's true but I'm thinking it's higher percentage than that. My alternatives are to heavily modify the heater ac unit I just got or rebuild my old rusted out heater box and go down the road. I decided to rebuild and picked up a newer heater core today plus the gasket kit today reseal the heater box. The gaskets are foam rubber and runs about $25. The heater core was $50. Now due to my car being a factory ac car, I'm going to use an evaporator out of a 96 sentra that I picked up because it is the right size and it already uses R134. So after looking at the sheet metal and cutting out the cancer rust, I cut a 3 inch wide strip of 22 gauge sheet metal to replace the rusted section. I ran it through my brake to make the bends I need. I have a lot more to cut out of cancer rust but I will do one section at a time. I decided to cut out the whole bottom of the box and start over rather than try welding new to pitted metal. I could look for another heater ac box in a wrecking yard but I don't want to even know how much that will cost. It will be faster to just rebuild what I have and if I found another unit, I might have the same problem with rust on a 50 + years old part. Chop, Cut, rebuild and motor on! #designsbyandrew #metalworking #metalworkingnation #welding #fabrication #fab101 #migmonkey #sheetmetal #chevroletbelair #chevrolet #64belair #rust #heaterbox #acbox #bella #belair #restoration #xframe #bbody
