A pressure test can be done at a Rad shop. You could install it and look 
for leaks, :)

No, It's not a good idea to run without a thermo. Fix the overheating, 
don't try to club the symptom over the head with a club.

The water pump is expecting to 'see' the resitance provided even by an open 
thermo. Put in a good OEM one from the Potterfolk, back flush the coolant 
system with a water hose, install the new Rad, add phosphate free coolant 
along with distilled water, make sure you have no leaks and that the cap 
keeps pressure (15psi is required to keep the coolant from boiling), 
confirrm your timing is right, you are not running too lean (air to gas 
ratio), and look in the rad while the car is just warming up- See coolant 
flowing? Fan comes on? Now is coolant flowing? Might be the waterpump is not.
