    1. Provide some photos of the old and new pump.
    2. Is it possible you were sold the wrong pump?

    North America 2G Prius has four coolant pumps:

    1. engine coolant (mechanical, spun by engine crankshaft pulley and serpentine drive belt)
    2. inverter coolant (behind driver's headlight assembly)
    3. cabin heater (on firewall)
    4. engine coolant heat recovery system (next to CHRS canister in LF fender well)
