    C1 Radiator, clank,bang,boom...

    Hello
    Such a beautiful day in California, just had to go for a little spin. Well I've rebuilt just about everything you can rebuild on my '59, including a recent engine overhaul...Well anyway, I didn't get 5 miles from home, before I ended up racing back to the safety of my garage. You know, the place you keep all the fire fighting equipment. This time I heard a loud banging under the hood, and it felt like the engine block was cracking in half. In my driveway with garden hose in hand, I carefully raised the hood. The top radiator hose was convulsing violently, and I'm pretty sure the clacking noise,and I do mean loud, was coming from the thermostat housing. On my engine rebuild I assumed (there's that word again) a new thermostat would have been inclued. Anybody else think it's a thermostat? How could a new one go out so quickly. Thanks,Tom

    may have been a pocket of air(cavitation). let it cool, fire it up and see what happens.You can test the thermostat by placing it in a pan of water, bring it to a boil (not the carbuncle type). best to do this when wife not in kitchen.You'll be able to see at what temp it open if you have a thermometer Good luck, mike. .

      You can get bad thermostats out of the box. More likely, it was put in backwards.

      What was your temperature gauge doing while all this was going on?
