Re: 1937 water pump removal

Subject, early cars discussed here being converted to a pressurized system. This may be being done to give the car a higher boiling point to overcome boiling over. It seems like an awful lot of work vs. just fixing the overheating problem.
The radiator core, being perhaps 80 years old will not think kindly about being pressurized, especially since it wasn;'t designed to be.

The bushing type pumps on 35-37 also will not be happy, the packing may weep or give way under pressure, again not designed for it.

Possible Causes:

Too much paint on radiator
Junk in rad
Excessive WP clearance
Bad T-stat
Junk in block

Pressurizing the system will not fix any of these things
