Re: 60-66 Radiator Over flow tank

Does anyone know if there is a certain cap that needs to be used on our radiators when an overflow reservoir is installed? I have a 13# cap with a lever on it (to release pressure it think). Im wondering if the pressure is too high for my cooling system?

I have a 4 core copper Harrison with the Ford overflow / wiper fluid combo (like '64 Shortbox). Seems that the coolant in the radiator disappears yet there will still be coolant left in the reservoir. Its as if the cap doesn't let the cooling system pull the coolant back into the radiator when everything cools off.

Never seems to run hot. 190 consistently. Can get 210 when towing and over 100* ambient but never boils. Running a 19" mechanical fan with the heavy duty Hayden clutch.
