SURPRISE!
One of the HVAC pipes I pulled to swap (and un-swap) the radiator developed a leak yesterday. It's an original hose on the original connection. But touching it made the O ring fail a couple weeks later. Cool.
Just why must they add this complexity of O rings and matching complex plastic parts!? You guys so deserved to lose the war because I bet every Panther had that same kind of stupid over-engineering on it too, but did you Germans learn anything from being overrun? APPARENTLY NOT.
Literally have NEVER had a $5 rubber hose fail for that stupid of a reason.
