S80 coolant overflow tank 2nd hose??

Post by 850TurboTurtle » Fri May 22, 2020 8:17 pm

What is the second hose connected to the S80 coolant overflow tank top? It goes down and into the engine cover. I bought a replacement coolant tank and it only has one hose nipple on top/ I'll be ordering the right part, but I'm curious where that other hose goes.
