I suspect the problem is that you are not properly bleeding the system. I had the same problem early on when I underestimated the bleeding process. When air is trapped in the system it expands at a much higher rate than the water. Therefore, if (when) you have a bubble of air at the water pump or the radiator it will swell to many times it original volume as the system heats up, forcing out a gallon or so of water. You shut off the car, let the system cool, add a gallon of 50/50, form a new bubble, and start all over again. Short term you need to bleed the system at both the thermostat housing and at the small hose at the top passenger side of the radiator and get the air out. Be very careful with that radiator hose if you still have a plastic tank radiator - the barb where the hose connects to the radiator was fragile 25 years ago, guess how it holds up now. Make sure to fill the system with 50/50 - even if your spewing a gallon a day you have to use the right stuff. Bleed it properly and you probably won't spew. Even with bleeding its helpful to squeeze the large hoses in the engine compartment to help work out the bubbles faster. That done, order a new cap for your coolant bottle, and bleeder kits for both the thermostat and the radiator. All in all you will spend less than you have been spending on Prestone the last week, and your problem should go away. Everybody has the thermostat bleeder kit and radiator caps, as far as I know only Toby at Delorean-Parts.com also has the radiator bleed kit. Be sure to confirm with your vendor which coolant bottle you have when you order the cap, is it plastic (original and needs to be upgraded or you will be buying more Prestone soon), it could be Stainless, aluminum, or a European bottle which I think is steel but finished black. My Aluminum bottle does not use the original cap, so make sure. Keep cool.
