Bill, Sounds to me like a bad cap. For each pound of pressure at the cap, it raises the boiling temperature about 6 degrees. A 16 lb. cap should be fine. Good luck, Gary Bradshaw, Ft. Worth, Texas

After doing the heater bypass thing so I could take the Coronet out tomorrow, I noticed that it has running a little hot on the way up to get gas tonight, which is odd 'cause I nearly froze my a$$ off w/ the top down. I ran a loop from the water pump directly to the intake port. But the more I think about it, I'm bypassing the thermostat right? I'm thinking that's why it's running hot. Should I pull the loop hose and install bypass caps on the intake and water pump nipples? Also, my car has a 13 LB cap on it (no AC). My service manual says 14 for non-AC, and 16 for AC. Is there any reason that I can't put a 16 LB cap on a non-AC car? Third-I noticed that the rad was a little low. I filled it up and now it's pissing out the overflow like a racehorse. It has calmed down after running it a little but is still pretty constant...Is this normal? Is this thing like my Model T where you don't fill it up all the way to keep it from peeing? I'm thinking about rigging up an overflow bottle too. Any suggestions? Bill M65 Coronet 500 'vert
