my 190 has the electro magnetic fan clutch. When i let it idle and watch the fan it is free spinning and is being entirely cooled by the elec fan.which will kick on at just over 100 c when driving stop and go the temp will fluctuate between 80c to 100c. it has never overheated but was wondering if this is normal or should i try replacing the elec magnetic fan switch if there is such a thing.....

 

thanks forcedinduction, it was the switch a three prong thermal switch right in front of the engine....now the temp stays even no matter the driving conditions....big relief
