Well seems as though my xjs was used as a combine by the previous owner... all taken from between the radiators

I got 165ohms. Which registers over 100c probably boiling? No steam or leaking from the radiator cap. I've heard the advance can cause an overheat? I'm going to clean the radiators when I get the chance but I'm wondering if my centrifugal advance is the issue. I know I had to oil that sucker and it moved but never really wanted to snap back.
pure water boils at 100c STP (standard temperature and Pressure) 1 atm
your system cap should hold another 16 to 21 psi or 1.3 to 1.5 atm
so it should not boil at 100C

It looks to me that it was working correctly.
make sure it is topped up and not low on coolant...
and don't do like me and forget to put the cap back on.... (both of them)

it still would be nice if it was running a bit cooler.
