Normal Operating Temp of 1978 450SL

Hi,
I'm new to the group so maybe this posting is better elsewhere. Please let me know if there is another forum for the topic.

I've got a 1978 450sl and at the last oil change the mechanic said that it was running a little hot for this cool/cold time of the year. It was about 200 degreees F and so he suggested 2 things. First, change out the thermostat or worse, R&I the radiator and recore it. As it turns out, the themostat was stuck and so he replaced it. Now he is OK with the 25 degree F reduction in temperature (at 175 degrees F). But, my question to the group is, what should be the normal winter/summer temperature of my car? If it is 175F during winter, won't I see 225F+ during 100F+ summer days?

At what point should I become concerned?

Temperature

I've got a 74 450 SL and it runs around 175 degrees all the time.

I think that is what the manual says it should be at.

Hi Aaron,
Thanks for the input. It seems to be operating OK now. With a little experience on the temp I do not panic when it temporarily goes above the 175-185 range.
