m radiator

[nateinia]

anyone sell a new non presurized radiator for a M. Every catalog I have shows only pressurized ones. My radiator cap just says water on it and I could interchange it with the fuel cap. This is an early model serial # 43,xxx. Thanks

Not that I have heard of. a good radiator shop can graft your neck on the pressure radiator. Jim

dumb question, my two 39 m's, 41 m, m with 56 engine, and the 53 w-6 all have the same cap, how do you tell difference between pressurized and non-pressurized systems?

Mainly, the non pressurized say WATER on it, and will fit the gas tank as well.

Never seen one, but the pressuized will work, if you can get it to fit right.

thanks John, was just wondering if I pressurized a non pressure system it would affect anything.

The radiator is the only part of the system that is NOT pressurized. Engine, water pump, etc. are all the same. Installing a new, pressurized radiator in place of the old, non-pressurized radiator will not cause any problems.
