This page will display the procedure for making an extremely significant heating improvement for a VW bus.
The first portion shown, is absolutely vital, and that is, the display of the engine temperature.
Please focus on the red LED digital readout mounted below the dash, which monitors the engine temperature.
I intend to add another similar gauge, that reads the engine compartment ambient air temperature.
These gauges can be found at this site (note that you'll need to acquire a mounting bracket also):
As the engine relys upon air to cool, the regulation of intake air, is critical to ensure the engine does not overheat, and yet is able to divert warm(er) air for heating the interior.
Next, is the controller, which is merely a radio frequency remote control unit, that controls a servo motor, to operate the regulator.
I found out later, that I could have used a servo unit meant to control the air flow valves in the heating and air system from a newer junked vehicle, although I would still have had to design some kind of comtroller, and this system is cheap enough, and certainly serves the purpose, especially since the controller, and servo(s), are sold as a kit at this site:
Here, I am relocating the blower motor mount, and then the fuel vapour canister, to make way for the flapper shaft.
