The heater cores are fairly fragile and I have seen a friend blow his up
while pressure flushing his radiator system. To protect the heater core,
you should stick with the stock 6 lb radiator cap. Many people use 10 lb
caps, but this can cause the heater core to bulge as it apparently won't
take this kind of radiator pressures.
On a separate note, I finally measured my radiator temperature last night
in my series II car and found that my temperature gauge is reading 10
degrees too low. I seem to remember someone (Jarrid?) saying that the
gauge can be adjusted. I looked at the gauge and the sender, and don't see
any obvious mechanisms for adjustment. Any advice is much appreciated.
