Default Re: Leakage from radiator cap 1937 85hp

Still have an over flow problem; now has turned into an over heat problem. I think it is a bad thermostat or bad pump(s). Today I drove a short distance and the temp was 170-180 degrees. Coolant was weeping out of the (loose) cap. I came back to the barn. By the time I got the garage door open, the car heated up to 200 degrees. I pulled in and let it run for a few minutes. It was at 212 after just a few minutes. After about 6 minutes of running idle, coolant started bubbling over. About a quart of coolant was ejected. I shut the car off. I am going to try the thermostats first; then if no joy I will change the pumps. Have been advised to restore the radiator too. Thanks. Anton.
