Jubilee rad

[JJUK]

The rad currently on my jubilee has a non pressurized cap should I have a pressurized one or not? Or is that rad designed to be non pressurized. How do I tell? Thanks!

The Jubilee original radiator is a pressurized system.

Ok so should I just put a pressurized cap on it then?

I believe the original cap was rated at 4 psi., and if the tractor was being run in a very hot environment, then you could get a 7 psi cap for it.

Great thanks! Wonder why there isnt one on it now

Your Jube is 70 years old. It is on its third cap. The owner had a newer tractor that was still working every day that needed a good cap for so he stole it and replaced it with one from an older tractor.
