You don't have an overflow jug. How much coolant are you putting in the radiator? Look on the side of it and you'll see "Fill Cold" marks. If you put in more than required to maintain that level, it is going to puke out the overflow once it gets hot and expands- it has nowhere else to go, and the pressure cap is going to relieve pressure to protect the system components.

This is not directed at any one person, but is generic based on what I see on DF's, at cruise nights, and in helping people with old car problems. Lot of y'all need to remember something very simple.

YOU ARE NOT DEALING WITH MODERN CARS. YOU ARE DEALING WITH OLD CARS. THINGS ARE DIFFERENT.

Anyone with an old car needs the factory service books for it. They will tell you almost everything you need to know to keep your old car running happily. At the very least a Chilton or Motor Professional Trades edition that covers your car.
