An old but excellent thread, Thanks Ohio for taking the time to post your work. I am getting ready to do the job my self now, pump and Tstat (w/bolts) on order. I do have a diagnostic question though. My vehicle (07, 3.0, @79k) is not showing the same symptoms. My symptoms are; coolant leak (~1l per day) from the pump/Tstat area, 2 low coolant alarms, and the loud fan noise. At 79k I am going to install the parts no matter what, I am just doing extra research to plan for the worst. Anybody have an additional thoughts? Thanks in advance.
