Cooling Fan Mercedes C class 180 Executive

Asked by Dec 07, 2018 at 05:19 AM about the 2013 Mercedes-Benz C-Class

Question type: General

We have just bought a Mercedes , and the temperature gauge was showing
high 120 occasionally  and the fan was kicking in . We took it back and they
have replaced the thermostat  .  We have just got the car back , and noticed
yesterday after only a 15 min drive when we stopped the car, that the fan
was going again very loud . It did stop when the key was taken out the
ignition . The the guage is not showing high anymore !! Please help is this
normal for this car  or have we bought a bad car ,  The Research I have
done isn't helping  us . We have never owned a car where you can here the
fan when standing outside the car ?

I have heard many a fan running while outside a vehicle. Not sure what your definition of loud is? Give us a decibel rating so we know normal vs needing repair.

Hard really . Just a normal fan sound , It doesn't sound wrong just quite loud , This is the newest car we have owned so perhaps we are just not used of it , and i have never noticed a loud fan going while stationary with any of our much older cars before . it's going on and off at random ,everything else now seems fine no overheating , Just wondered if this is what a Mercedes fan is meant to do !! (Never had one before ) Should it start and stop even in Winter and short journeys ? we can't really hear it while driving it's only noticeable when the car stops ,and does stop as soon as we take keys out , Havn't a clue if this is Normal for the car or not . Any C180 Mercedes owners out here please advise !! Thank you , only had it for 2 Weeks and we do like it ,drives well too just a little worried about the fan issue ,
