Alex, Thank you for the TSB, it appears that it is, indeed, the problem. However, MB Canada has never had that particular bulletin nor the associated parts in their system. It appears that the TSB and the parts were an MBUSA issue and at that, only for those in the southernmost states. Being further north Canadian MBs didn't seem to have as much of an issue.

I have the parts manager for the local MB dealership trying to get more information out of head office in Toronto for me.


Re: the overheating problem. It appears that I am in need of a new radiator (dammit). I've replaced the thermal switches and flushed the cooling system thoroughly and the car is still running quite warm.
I'll post further developments as they occur.

Thanks all for your responses.
