My 1991 350SD has a bad evaporator. I got the heater box out -- what fun that was!!
According to the manual, I am supposed to remove the heater core before I remove the evaporator.
I took the heater core cover off and took the support for the three pipes off. There is supposed to be a retaining bracket inside the area where the heater core is and I am supposed to unscrew it and remove the heater core.
However, I have nothing that is screwed in. What I have is a shaft that goes through the opening that is attached to a vacuum element that rotates the shaft.
The heater core will not come out because the bottom pipe hits the shaft when I pull it up. It seems like the shaft has to be removed.
Has anyone done this and can tell me how to get the core out?
