Interesting!!!!

When I go to the parts counter at MBZ of Fresno and ask for a thermostat for a 617.950 engine, I am asked if I want the 60°C or the 80°C device as there are part numbers for both of them. Only says me???

Again, to adress the original question, you will not harm your engine by driving it with 60°-70°C coolant temperatures until you have the time to take it in for a new thermostat...Robert

Very important key point there. In the short term, its acceptable.
If its opening at 60-70*, its already begun to fail. It needs to be replaced with the proper temperature t-stat asap before it fails completely.
