Failure is more common and happens more often with these thermostats due to the internal temperature probe that goes down through the center of the housing. It is much better to replace this as a preventative measure to prevent engine overheating.
This is one of the most often neglected services I see on the M272 engine. Even at 100,000 miles, you often see the tank has never been changed, and you can recognize that by looking to see if there is a factory crimp hose clamp still in place on the fluid return hose at the bottom of the tank.

If you are doing a complete power steering flush you will need to have 2 liters on hand. It will take approximately 1.5 liters to flush all the old fluid out of the system. If you want to do this service on your Benz, please see related products below for our 40K service kit. 272273

In this 10-minute instructional video, Kent will show you the location of the thermostat on both engines, explain why they should be replaced every 40,000 to 50,000 miles, and wrap up with installation tips that should help you do it yourself.

This is not a difficult part to replace, but it does require you to remove the belt and one pulley. A good time to replace this part is at the 80 to 100K inspection interval since you will already be removing / replacing the belt and pulleys.
