107 new fan clutch makes noise and how do i test it
I just installed a new sachs fan clutch in a 380sl. Every time I start the engine there is a thumping sound in the clutch for about 5 turns then it goes away and the fan sounds normal? Also with the engine hot I am able to stop the fan with my hand at idle, is this normal?

The fan should spin up and roar when you first start up, not thump.
I suspect it's either installed incorrectly (if that's possible) or defective. Check for loose bolts, etc -- the fluid will all be on the bottom at startup, so if it's loose, it will thump until the fluid spins out. Peter
