[TR] [EXTERNAL] - Re: Radiator overflow bottle

[Joe DeMuth]

We had a fellow in our club attempt to use a coolant bottle and new radiator cap designed for a pressurized system. All was fine until the vacuum created when  everything cooled off. The vacuum created in the system collapsed the heater core to the point that the spring clips that contain it fell off. The next time he drove the car the heater core started to expand like an accordion. Fortunately the tranny tunnel contained it and he noticed. He found the clips on the floor of the passenger leg well. Luckily the heater core did not spring a leak.
