Re: Running a bit hot,,,Question!

Dennis,

Thanks for the info, its still running a bit hot, next week i will try a different approach.

I will have the radiator flushed, cleaned and welded ,today i found two pin holes and a minor quarter inch crack along the back of the radiator and maybe i'll remove the 18 psi cap along with the trans cooler.

Jay,

65 B/B Coronet 500.

Looks like you have been getting some very good information on cooiing
systems. Just a recap of radiator caps:

The pressure cap increases the maximun pressure in the system AND
increases the boiling point of the coolant in your system. The
increase in boiling point and pressure is approximately 3 degrees per
1 pound increase in pressure cap rating.

Therefore a 13 pound cap will increase the boiling temperature of your
radiator to approximately 242 degrees. (my choice for a cap)

Therefore a 18 pound cap will increase the boiling temperature of your
radiator to approximately 266 degrees. (very hot)
