I think I need a new one -- where to get one (without going to the dealer)? Whenever I go up a hill, it just starts spewing coolant out and leaves a trail, instead of pressurizing like it should when it gets hot. Then of course, it starts overheating because it's missing coolant. I looked on line and found a few caps for sale, but none of the little round tanks. Would a junkyard one be a possibility? I never trust used radiators, but maybe?
