comparo 93 to 95 300D...

[vstech]

I noticed on the 93 the coolant air bleed to the overflow/expansion tank is on the block as part of the thermostat housing. cast aluminum. solid improvement from the 617's plastic nipple on the radiator that always breaks.
I just got the 95 in my shop, and am surprised that MB put the vent line back on the radiator... why?
it is higher on the coolant system, so I guess I see an advantage of burping any air out of the system, but plastic is SOOOO weak! and so easy to damage...
of course, the 95 completed a tripple axle on the interstate, and did not break the vent line... so they may have made it quite durable, I just don't know what to think of it.

also, I thought the non turbo cars did not have the gills on the passenger's front fender. this one does. also the replacement my customer is looking at also has it. is it different from the turbo's gills?

The 2.5T in the 124 and 201 get the gills, and the 606 gets the gills. None on the 603. Just a later-model thing (except the '87 201).
