I doubt I will run out the mileage on these now. Car idling in the driveway for 20 minutes with no aux fan running and the water temp is sitting right at 96C. Happy happy.

Composite impellers don't have any galvanic corrosion issues. My original lasted 262,000 miles before it finally started to leak. The impeller still looked good. Always stuck with the OEM coolant though.
