BMW E31 840ci M60 Water Pump and Viscous Fan Replacement ↗
Contributor photo guide to replacing the M60 water pump together with the viscous fan and coupling on an 840i, done preventively because old fans can disintegrate. The fan unscrews clockwise after a few taps on a 32 mm spanner; O-rings get a smear of silicone grease.
Tools mentioned: 10/13 mm sockets and extensions, 32 mm fan spanner, hammer, silicone grease
