B radiator

Midway · Feb 20, 2019

Installed a new radiator on a farmall B. Afterwards I read it was for a pressurized system. My B does not have a water pump. Will this be problem? It fit and part numbers said it replaces the original parts number. Thanks for any replies.

Pressurized means the radiator cap seals well enough to the point it develops pressure inside the system. This is caused by the expansion of the water due to heat. It doesn't mean your tractor now requires a water pump.

What it does mean is that now the pressure can find leaks somewhere else if there are any weak points.

If I place a non pressurized cap on the radiator if possible would it help?

drill a very small in the radiator cap, no pressure can then develop

It will be fine as-is.

Good update, IMHO.

Thanks for replies. I appreciate the feedback.

The block and hoses can deal with the modest 5 to 7 psi of a pressure cap. The radiator was the component that could not. the new radiator will stand the pressure, so a pressure type cap is fine. level of coolant should be about 1 inch above the cores, looking into the cap. Jim
