I can see that lifting eye where the heater hose connects, but it does not appear to be leaking. Will check it again though and let you know if it's leaking. Thanks for the tip MB DOC! I appreciate all the help you offer to this forum.

Found these posts by glenmore that seem to describe the problem on this car. Thanks glenmore for posting this, it took me awhile to find it, but gave me some hope.

Please take a look and offer any comments you may have about replacing the hose in question. It is referred to in the online parts catalogs as "Cooling Hose", and is MB part number 104 203 03 82, WorldPAC SKU # G2021-71771. I purchased a new hose through Carquest using the SKU. It was 7.59 with tax.

Anyone with R&R M104 intake manifold experience

The tricky thing is trying to gain access. I want to avoid pulling the intake. And according to the posts by glenmore, his tech did the hose replacement from above. I am wondering if there is any special details to know about when doing it this way. It looks like you can get a bit better access by removing the throttle linkage because it blocks the path between the intake runners.

Thanks again, Brian
