Water Pump Failure
Hey all, I'm a new poster, long time lurker, and a 08 550i driver. Yesterday as I was on my home from work my power steering went out and my car notified me that the dynamic drive had a charging failure (talk about a heavy steering wheel). Not too long after that I receive a low coolant and pull over at a close by safe location. When I looked under the hood I saw the drive belt sitting off the pulleys and coolant sprayed all over the engine compartment. I have not had the chance to take a close look at the damage but I'm going to assume I had a water pump failure (possibly the pulley failing) causing the belt to slip off.
Ordered parts:
Water Pump
Integrated Housing Thermostat
Thermostat / Thermostat Housing / Water Outlet Seal
Temperature Sender / Sensor
Coolant Pipe & O-Ring
Billet Aluminum Water Pump Pulley
Am I missing anything or anything else that could be impacted? I'm going to check for hose leaks once I can get into the car.

The only thing I would suggest is getting a tensioner. If not the belt might keep coming off and you may have continued pump issues. Make sure you if you do not get BMW coolant then buy 100% with distilled water but I would only suggest BMW brand to keep your radiator clean.
