Yes, rebuilt valves are available, I know Larry Stock at Pantera Parts Connection in Carson City has a number in stock ready to go as I rebuilt them for him!

I am sorry to hi-jack this chain but I am currently having my Pantera restored. The original heater valve is very stiff and potentially unusable. The restorer wants to cap the heater hoses kind of indicating the valve may not be stable.

Is there a replacement valve available - either original equipment type or aftermarket equivalent.

I am the original owner and this has not been on the road for nearly 30 years. It is a 1974 L and I never had any of the typical issues with the vehicle. I drove it every day in the Summer to work and around town. Just before I parked it the heater valve became difficult to operate.

Thank you in advance,

Jim Kosloskey

I also thought the valve piece that allowed the fluid to pass had to be installed in the right position (90, 180, 270, or 360 degrees within the
pipe) to work properly? You'd have to try it in any of those positions to see which one works.

There are three types of heat transfer that need to be accounted for.
   Conduction
   Convection
   Radiation

The foil on dynamat is an effective way to reduce *radiation* heat transfer if it is placed in the engine compartment so the foil faces the engine and other sources of heat.
