Finally had to have something fixed!

Inverter pump or Engine pump ? IIRC the inverter pump is covered by Toyota in a TSB or recall notice.

 

Ah, right you are. I tracked down the SSC, it indeed is for 2004 through some of 2007 MY cars.

Anyway, kudos for avoiding the dealer junk additions.
Hopefully your new pump will last for many years, but be aware that a DIY replacement is pretty easy. I define 'easy' as something I performed, so just about anybody else can too.

The pump on my car never acted up, but I replaced it around 120k miles when it was time to exchange the coolant fluid. Similarly, I plan to replace the engine pump as preventive maintenance when I exchange the coolant for that circuit. This works out to cheap insurance (about $125 for both pumps.) I avoid inconvenient downtime for the car, and so far as my wife is concerned, the Prius NEVER breaks down.

 

Just like I alway say, your plugs showed virtually no wear at all. I would have cleaned them with a wire brush and reinstalled for another 128,000 miles of worry free driving @ 57 mpgs.

 

Sorry Usnavystg wire brushing plugs is a no no. Doing this leaves particals of metal from the brush embedded in the insulator of the plug, providing a path for the ignition high voltage to the metal side tube of the plug. This can be seen after brushing as a discoloration of the insulator. Light sand blasting is ok followed by a clean air blast to remove any sand particles trapped in the plug. Fitting new plugs is better.

 

Where did you learn how to replace the inverter pump?

 

I suggest you write to the Toyota Customer Experience Center, provide a copy of your repair invoice, and ask if they will be willing to provide you a refund for the inverter coolant pump replacement. Cite the LSC (Limited Service Campaign, do a search for that on PriusChat to get the details) and point out that the problem apparently continued to persist with the 2G newer model year production. Good luck.

 

Here is a thread that I initiated prior to announcement of the LSC:

Gap on those old plugs needed to be adjusted. But that age, it's probably wise to replace with new ones.

 

Damn! That inverter pump is expensive, and that is Texas rate. I wonder how much it cost in Los Angeles?

 

Interesting to note how short the insulator is on the Bosch plug compared to the NGK.

 

Which shows you the plug is probably in the wrong heat range and may not last as long as the original equipment plugs.

 

Knowing the Bosch part number is the only way to tell the heat range as other factors such as depth and dia of insulator and, dia and material of central conductor. Bosch often use copper for the center conductor because of it's heat conducting capabilities.

If it is in the wrong heat range the life of the plug would be the leased of my worries. Pre ignition due to over heated spark plugs can be very damaging to pistons, and the anti knock censer in that situation is of no help raising combustion temperature by retarding the ignition timing.
