Hi All,

We just acquired another 300D W124 2.5 turbo from a family friend.
Car runs out very well, has good power.
Only complaint or question is that it runs hotter in traffic and at lower speeds. Like it gets to the 100 degree line, the line between 80 and 120 on the gauge I assume thats 100. Our other car doesn't do that and this has me a bit worried.
On the freeway it stays at a constant 80 or a touch higher with no fluctuations at all.
The top hose also collapses after running for a long time, almost like the system goes into a vacuum state.

Any ideas on what this could be? Ideas suggestions as always appreciated.
