coolant change

  1. How often do you need to replace the air filter and coolant?

    I bought my 2011 Smart Fortwo Pure last year. It had about 35,000 miles on it. I don’t drive it much but how often should I be replacing the coolant and air filter?
  2. Thermostat gasket

    I drive a 2008 Smart For Two Passion. I'm going to change out the coolant. The mechanic said I might have to replace the thermostat gasket. Does this car have a thermostat gasket and is this a normal procedure? Are there such things as metal gaskets? Thank you, Jason
