[W126 Coupe] Overheating

[Camran Nassiri]

My 1991 420SEL with 147,000 miles is overheating at about 89 degree outside temp.  I checked the auxiliary fan and it is working.  Would a new radiator solve the problem?  If not, any other ideas?  The synthetic oil has been changed every 5,000 miles and recently replaced ant-freeze and flushed the radiator.

Thanks,
Camran
