run car @ 2000 rpms with defrost heat on high until you see a dramatic reduction in temp reading should just take a few minutes, to bleed air out of system. if it got up around 120 i would be getting cautious. this is per mercedes mechanic who has all the certificates and he said this is what is recommended

i had replaced a bunch of parts and found out it was a bad temp gauge.
