The cooling system is one of the major weak points on the N62 engine in the 550i/650i. The water pump itself won't last more than 100,000 miles in most cases and the engine itself is prone to coolant leaks from multiple locations. So a major 550i cooling system overhaul should be planned before the 100,000 mile mark. Aside from obvious leaks the 550i water pump will also squeal or screech indicating the bearings inside have worn. This package covers the water pump, thermostat, and radiator for the 2006-2010 E60 550i and E63 650i with a manual transmission.
The entire cooling system on the 550i is susceptible to leaks and poor performance. The condition of the rest of the cooling system should be considered along with the water pump and thermostat. Replacing the water pump will expose the front of the V8 engine where more problem areas may appear so plan accordingly. The biggest problem is the V8 valley pan gaskets and inner coolant tube seals. The tube carrying coolant through the valley is prone to leaking and replacement is a major job (see our valley pan pipe kit here). Additional items recommended to be replaced during the water pump job are: cooling hoses, expansion tank and cap, temp sensors, drive belts, and pulleys and tensioners.
