  • Radiator caps

    What pressure rating were the cars equipped with originally? What pressure rating are folks running with the 50 year old cars? I'm losing a little bit after shutoff.

    Radiator caps

    Back in 2009, we had quite the discussion on radiator caps and what to use on our Squarebirds. Bart Como and Sal came up with some great information which ended up being used in a VTCI Scoop magazine. Here is the link to that discussion and you will see what Alexander had to say about this and also what Bart, Sal and others said. I have added this link to the TRL.

      Thanks, Ray

      That was my observation; I didn't find any specs in the manual which is surprising. So in summary, the original equipment was a 13# AC cap, and the 7# was primarily used for water/alcohol only in the old days. Now you'd use a lower pressure if you were concerned about integrity of the cooling system and higher if you wanted to increase your boil-over point.
