check the maintenance schedule for service requirements. i would wait on the pump, but it depends on your level of caution.

 

You might want to pick up a rebuilt Combo meter and have it in stock when that starts failing. Its pretty easy to install diy. Mine blinked for almost a year but had one in stock ready to go when it finally failed.

 

If you had it for a year how could you get a rebuilt one with the correct mileage?

 

Which coolant pump are you referring to: engine or inverter/transaxle?

If you see pinkish or whitish residue deposited on the interior of the engine coolant pump pulley or on the AC compressor housing which is below that pump, I would change the pump as the bearing is beginning to fail.

If you are referring to the inverter/transaxle coolant pump, there are no warning signs for that pump prior to failure. Maybe your car received a replacement pump under the recall program, you might want to inquire into its service history. I would say it is a good idea to replace the pump preventively if 100K miles have been logged on the pump, as it appears the current design pump is not really any better than the original equipment pump.
