Search forum for "Cooling Overhaul".
You are sitting on a time bomb.


Testing Fan Clutch: if you want to keep your fingers, keep them away from the Fan Blade.
With engine hot and running, hold a piece of paper behind the Fan Blade, it should "flap", indicating that there is adequate air flow.

There are countless people with blown head gaskets b/c of failure to do a cooling overhaul.
In fact, I would not be surprised the #1 cause of death in an E39 is blown head gasket.
