The Stovebolt Site Forums The Shop Area Engine Shop 42 216 cooling problems UPDATE

I don't have to remind you but this is a 50+ year old engine that has survived. Be kind to it. We are your best bet on the internet.
1. Put the 160 degree therm back in with a 50/50 mixture of antifreeze. Should take a little over 3 gals of the 50/50 mixture.
2. Put on a 5-7 pound rad cap no more.
3. What do you mean that "the advance springs were broken'? Do you mean the 2 small springs under the distributor breaker plate?
4. Does the distributor turn when you blip the throttle?
5. It may be as you say a small crack somewhere in the head.
