1974 450sl RUNS HOT

I just bought my first 450sl (1974). The heat constantly runs and cant seem to control the heater thermostat. Suggestions or direction?

Welcome to BenzWorld! Try the R/C107 forums located under the Roadsters subsection of this site. That is the chassis designation for your car (R107) and the folks there will likely have the best advice for you. Good luck.

My '79 450SL always ran hot. I finally changed the thermostat and had the radiator cleaned out. Now everything is running cool. I also put on a new radiator cap. These are some of the things you should check. Also, the clutch on your fan could be going bad. Check it too. I think that covers everything. Cecil...........
