A, B, C, and Super A Radiator Warning
Farmall A, B, C, and Super A
tractors that are not equipped with a water pump
must use a NON-Pressurized radiator.
The head gasket used on these tractors has large
water jacket holes without reinforcement rings for
maximum coolant flow.
If the less expensive pressurized radiator is used,
it will eventually cause the head gasket to fail.
Our radiator is more expensive but it uses the
original NON-Pressurized cap.
The water jacket holes in the
later style head gasket are to small to be used on a
tractor without a water pump and will cause the
tractor to overheat.
The only safe way that a pressurized radiator can be
used on Farmall A, B, C, and early Super A tractors
is if the head gasket is changed and a water pump is
added at the same time.
