Looks like I have an issue with the coolant pipe at rear of the engine that connects to the heads and has hoses to the heater core. Has anyone done this repair? Looks like there are a lot of items that need to be removed to get to it, curious to know how much or a bear this is. And whether my bad back can handle it.

Does anyone have a Bentley manual that covers this repair with step by step instructions? Thanks in advance.
