My 2005 Toyota Prius with 188,000 miles has a whinning sound when I start and when I turn off the engine. It happens 95% of the time. The dealer says it could be a water pump. What’s your opinion? ---

It should be easy to pinpoint. I doubt the water pump. I would suspect a belt, fan or power steering pump. ---

**_My Opinion Is That The Dealer’s Opinion And Toyota Motor Sales’s Opinion Could Be Correct._** Did the dealer show you the 3 page Toyota TSB (Technical Service Bulletin), written to help their technicians diagnose a “squeak” type noise during vehicle startup or shutdown in 2004 - 2008 Prius vehicles during cold ambient weather conditions ? The **Coolant Heat Storage Water Pump** could be the culprit. After checking the VIN (vehicle identification number) against Toyota’s information, the fix could be replacing the pump assembly with motor and bracket with what I believe is a “revised” part (the part number has changed). Toyota covers the replacement for cars under the 60,000 mile / 60 month warranty period. _ **CSA** _ ---

Hah wow, that’s a new one on me. I’m definitely not hybrid-savvy.
