Fan Clutch With Fan Blade.
Good for all T1N Sprinters, years 2001-2006, engines OM611, OM612, and OM647.
This is the complete fan and clutch assembly. Genuine Mercedes quality. This clutch is key to keeping your engine cool in the summer and under heavy loads. It kicks in around 210F and you all of a sudden hear the engine make a louder, whooshing noise. Many say their van sounds like a dump truck when it kicks in. Almost immediately after though, you should see your engine temperature begin to drop a bit.
If your engine temperature gets above 220 and you do not hear this fan clutch kick in, it's time for a new one.
Also, a broken serpentine belt can damage the clutch and/or the fan. If any piece of the fan is missing, it will be off balance and will wear out the bearings in the fan clutch very quickly.
It is best to change these as a set.
Recommended Change Interval: 100,000 miles
