20PSI Radiator Caps

[vex]

that's really peculiar to me. I've been running the 20 psi bar for the past few days and have been able to isolate and fix all the external leaks. When I idle the temperature gets up to regular temps but then will immediately start to cool. The E-fan will actually kick off which is something it never did with the old radiator and pressure cap. My Engine temps have been cooler too. Whether that's from the radiator or benefits of the cap I don't know. In the mean time I'll pick up a new radiator cap and see if I can't find me a recirculatory tank some where.
