While through the drive through, it nearly reached 100C. How can I lower the temp?

 

the cooling system needs to be checked.

fan
aux fan
radiator
thermostat

 

2000 E320 w/ 75k miles

When I'm cruising the temp is at 80C. Can we eliminate any of the things that need to be checked?

 

Can i have a picture of my 1995 E320, automatic, showing the change of coolant as mentioned in the above tread. I want to change the coolant of my car myself.

So I'll refill the coolant, leave the reservoir cap off, start the engine, and turn the heater on full? Then do I just let the engine idle for about 10 minutes? Then shut the engine off, top of the coolant and recap the reservoir?

Regards
