Thanks for writing back. Yes, I did fill it more than 3 inches from the top or the max fill line, so I was expecting it to spit out some coolant. I do have the hose running down the side of the radiator and out onto the ground. I don't have a pristine engine compartment, but nevertheless I don't need it making a mess. I will probably put an recovery tank on it at some point, I have one on my wish list, and I think it is a nice upgrade. I think it was just funny that it spit out the fluid after I shut off the engine, instead of while it was running. I think it is interesting that the coolant expands that much, 3 inches worth. It seems like quite a bit. When you're in the kitchen and boiling a pot of water from stone cold to 212 degrees, the amount of water in the pot does not rise a visible amount. Curious...
