I just bought a 1987 Ford 1-ton cargo van for my very small business. It has a 460ci motor. It starts and runs very smoothly. But here is the problem: After you start it and let it run for 7-10 minutes it starts leaking anti-freeze. I soon learned that it's not actually a leak. There is just no over-flow container. The over-flow hose just runs over the top and down the side of the radiator. So for some reason it is getting too hot and just over-flowing onto the ground. The thermostat seems to go up slightly as the motor warms up as it should, but never anywhere near the half-way reading. So what is causing it to overheat? Is it just a stuck thermostat? What else could it be? Also, is it OK for it not to have an over-flow container? Any advice would be GREATLY appreciated!!!
