Happy Festivus everyone! Part 30 of my '76 Mazda Cosmo restoration continues the Vintage Air Gen II Compac HVAC installation. In this episode I concentrate primarily on plumbing the system. I know I promised last episode that this half would finish off the install but it has been a lot of work. More than I first anticipated so you'll need to wait until episode 31 for the finishing touches (wiring and ducting). There certainly is a lot of plumbing in an HVAC system, especially when it all has to be figured out from scratch in a custom installation. But the plumbing is one of the most important parts of the install so it makes sense to pay attention to the details. Line placement in an engine bay can make or break the system. I've tried to make use of as many hard lines as possible for both the hot and cold side, which will go a long way in terms of reliability. Included in this episode: measuring and cutting high and low side hoses, installing fittings, installing firewall bulkheads, tricks for hand bending aluminium tube, the cut-and-weld method of tube bending, making brackets, silicone hoes, TIG welding.
