Dabie, of course I watched my temp gauge. At the time the needle went up about a gallon of water was already missing ! This happened so fast I almost couldn't believe. And yes, I checked the coolant level the day before. This is why I am so afraid now. By the way - the new bottle has a "low water" switch that will turn on a light (LAMBDA) in the dash and maybe a buzzer, too. Also I can check the level now by simply walking around the car. The water level can be seen thru the engine covers ! As long as there is no possibility to check the level on the stainless bottle (without taking off the cap) I won't install it anymore. Also the plastic bottle is cheap. About 25% of what some vendors charge for the nice stainless ones. Optically I still prefer stainless. But this is about the safety of my little engine. You proved the problem, too with your overflow bottle. Elvis & 6548 I also replaced my plastic header bottle with a S/S bottle and did not like losing the ability to check the coolant level. My solution was to add an overflow bottle so now I can see the level hot or cold. BTW the S/S bottle did not kill your motor. You MUST have had some warning. Were you watching your temperture gauge? You cannot see your plastic bottle from the driver's seat!
