Hi Everybody,
I have a '82 300d turbo and was curious as to the function of the small horseshoe shaped metal pipe that is connected to the water pump. It is attached by two banjo bolts. The best I can tell from looking around the internet, is that it's some kind or bypass pipe... but what does that mean exactly? I'd be surprised if it was "bypassing" liquid as it's very small in diameter. I really don't know, but mine looks pretty corroded. Also, what kind of symptoms would occur if it was bad/clogged? Do I have to drain the coolant to replace it?
I've really appreciated the bits of help that I've received on this forum and I'm looking forward to everybody's input. Thanks!
