1974 C10 A/C Hardline Routing
Hello everyone.
I have finally been replacing parts to get the factory air conditing working in my 1974 Chevy c10. I replaced the compressor with a pro6ten unit, and the condenser with a modern parralell flow unit. What I need to know is where the ac hardlines route once they go through the core support in the fron of the truck. I removed the original condenser when I did the cam about 5 months ago. I should have taken a picture of the hardlines before I scrapped it. Does someone happen to have pictures of the condenser and the a/c lines in the core support area? Or if someone could explain where they run to that would be great. On my truck there is a line that runs from the bottom of the evaporator and goes through the passanger side core support, makes a 90 bend and then stops. On the drivers side the stock rubber hose from the compressor terminates at the core support. My new condenser has #6 and #8 fittings on the drivers side. I found a hose shop in my town that can make new hoses/lines, but I would like to give them a general Idea of what is going on. And I would like to know myself. Any input, and or pictures are really appriciated. Thank you!

This may help. This is my 81 and I think it is pretty much the same fro the 73-87. Anyways, on mine the two lines are actually different diameter fittings so they only went on one way. But the upper one goes to the compressor and the lower line from the condenser goes back to the evaporator.

#8 will go to compressor, and #6 will go the the evaporator.
