I am trying to remove the heater core from an 85 300SD. Here is what i have found:

1.) Manuals indicate to remove the retaining screws and core should lift out, reading post at

http://www.benzworld.org/forums/w126-s-se-sec-sel-sd/1508647-how-remove-heater-core-heater-box.html

It appears we have the same issue, no retaining bar but shaft that is going to keep everything in. I suppose I have to remove the shaft?

2,) PDF 83-110 point 5 refers to retaining bracket 49. How do you get access to this? My 3 pipes go to the engine compartment under a metal plate that seems sits between windshield wiper and these pipes.

can anyone provide some guidance?

Thanks

Thanks for replying.

No, different equipment. The monovalve is located under the hood. The heater Core is located under the dash.
