Mercedes Benz CLK320 Repair Questions and Answers

Question: 1999 Mercedes CLK320 mileage: 99,000. The normal temperature of my car is about 80 - 90 degrees. When I use the air-condition system and especially when I am in the middle of a traffic jam the temperature rises a bit higher (95 -100 deg). Is this normal? Some told me it is normal, some told me I need to change the thermostat (I live in Cyprus and it is really hot in the summer), and some told me there might be a problem with the cooling system. What's your opinion?

Answer: The temperature fluctuations that you describe while driving in traffic are normal. Your car is at an age where it would be a good idea to have the cooling system serviced, flushing the radiator, replacing the thermostat and adding new coolant.
