OK.
I need to bypass the AC servo on my '79 300D.
It's warming up here and I'm tired of the coolant loss associated with my leaky servo unit.
I'd like to just plumb around the servo for the summer, and will eventually buy the kit from unwiredtools to reestablish cabin heat.

Which two hoses will complete the engine coolant circuit and bypass the servo and heater core?

Thanks!
