Toyota Prius Forum : “Las Vegas hybrid repair shops?”

You could come to MASSACHUSETTS  :)
I would assume you are talking about the coolant pump??
Bad news the pump are on backorder from Toyota.
Good Luck

Based on the video at Lucious Garage http://www.lusciousgarage.com/blog/comments/prius_code_p0a93_inverter_water_pump_seized/, it seems the inverter pump is not working. Yeah, the dealer told me they're on backorder. So I bought a pump off ebay for $130. It looks like it ought to cost $10 to make. The dealership wanted to charge $200.

Given that the dealer wants $200+ to install this doohickey, I'm tempted to do it myself. I know it shouldn't be too hard but I have some questions:

1. What needs to be removed to access this pump?
2. How do I drain the coolant?  Can I just put it back in?
3. Is bleeding the line necessary? If so, how?

shows the inverter coolant drain on the transaxle.

It also recommends a Matco Airlift http://www.sjdiscounttools.com/uv550000.html to prevent bubbles. But where do you get that special adapter for the coolant reservoir? Can you make do with the rubber adapters it comes with?

I still don't know how much coolant fluid is in there.
