I have a 350 sm blk. Problem is coolent coming out of the overflow. Replaced the thermostat about a month ago. Car has been driven due to getting paint done. What other issues could I look at that would cause
collent to come out of the overflow?

Thanks,

Coolant will naturally come out the overflow when the coolant in the engine expands. It will arrive at some natural level if you don't refill it and it isn't overheating. Installing a coolant recovery system will alleviate the overflow problem.

Install a new radiator cap that actually tests at 16 psi.... most new 16 caps test at 11. Test it before you leave the store. They have a cap tester. I had to test 5 to get one that did 15.

Install a puke tank to keep the system full.

Thanks for the input. I was thinking about a new cap I figured that would be the first and cheapest way to start.
