Water pump being replaced
06 330i 6speed with 127k had the original wp go. Threw a code that morning, (im guessing low flow rate, will put my reader on it today to confirm) later that afternoon , On the jersey parkway, low coolant level alarm, 10 seconds later overheat alarm and limp mode, quickly coasted off highway, fan in highspeed, and popped hood. Antifreeze spewing everywhere from the reservoir vent.
New water pump, thermostat, and aluminum screws purchased from thebmwpartstore.com for $427. I do all my own work ( like the eccentric shaft sensor!! On 5/2011) however local Indy shop is doing install of water pump and I'm looking at $350-$450 for labor.
The fluid was flushed at 52k however I knew I was on borrowed time regardless.
