What's the correct Torque for the bolts that hold this to the engine?

Willys Jeep Parts Tech:
20-25 Ft/lbs would be the torque

what material used this housing ? cast iron or aluminum?

Willys Jeep Parts Tech:
This can vary but currently they are aluminum.

Which thermostat do I use for a 1956 Jeep Willy w the F-4-134 engine? There is a 160 degree and a 180 degree choice?

Willys Jeep Parts Tech:
Both can be used. It more depends on where you are located. The warmer climates would lean towards the 812050 (160) where as the colder climates should use the 905594 (180). Thanks
