129 500 SL engine operating temp.

[MDE3]

My 1991 500 SL seems to run at about 100 - 105C most of the time regardless of ambient. I have never been in a stop and go traffic situation with it yet..so that makes me a bit nervous. Coolant appears normal in both level and appearance.

I did the search on here and found lots of posts about the 107 series cars, but not really anything definitive on the 129 when it comes to engine operating temps. The car has a hair under 80,000 miles at this point so I would be surprised if it has too much radiator build up/corrosion (it has been a garage queen for a couple of years with two previous owners)....but one never knows...I have only owned the car since May and put less than 400 miles on it at this point.

What are the normal suspects here..or is this to be expected?, Are there thermostat issues? Rad issues?


Thanks
