Just bought a 69 Mach 1 today and I had 100 miles to drive it home. First 15 miles was good. Filled up with gas then the gage read 3/4 H then hot the remaining 75 miles. Shut car off and radiator spewed out the overflow hose for 3-5 minutes. 13lbs cap. What's your thoughts? Thermostat & change fluid?
