My Gen 2, 2009 Prius is hitting 150 K Miles. Other than 5 K oil change / Cabin and Engine Air Filter changes, the only service I had to do was front right wheel barning change, Brake pads, tires changes. I did change the spark plugs just after 100K. What other service do guys recommend? I would like to keep my Prius for at least another 30 K miles / 2 to 3 years. After doing some research, I have come up with this list. 1. Brake fluid flush 2. Fuel induction 3. Transmission fluid flush 4. Inverter colling pump replacement 5. Engine coolant flush 6. Inverter coolant flush 7. Water pump coolant belt replacement Anything you guys recommend that I add or delete to this list? Do you guys recommend that I go back to the dealer for any of these? Any help will be greatly appreciated. Thanks Ash
the fluid replacement are all good maintenance, honestly most of my high mileage cars never did a brake flush. If the fluid is clear I wouldn't worry about. Not sure about 2,4 and 7.. to me it's unnecessary, the belt if cracked replace but they could last a lifetime. Not sure about what is fuel induction.. the cooling pump might be a good preventative maintanance.. the cooling pump on mine failed but it didn't throw codes or affect the car, maybe due to cool weather. Some experience a blown fuse when the pump fails (probably from Amazon replacements) I think they fail at more than 200k miles.
I’d consider most of that list, except #2, worthwhile. Has the coolant never been changed, both engine and inverter? I’ve got a spreadsheet translation of the Toyota published gen 2 schedule, and a version extrapolated to 240k miles (Toyota schedule stops at 120k). I can post in a bit.
Aforementioned 2nd gen schedules attached, a table format conversion of what Toyota USA says in the Warranty and Maintenance Booklet. There's both 120k mile version (per the bookklet), and extrapolated to 240k miles. Both Excel and PDF format:
Thanks for the response @Mendel Leisk I don't remember changing coolant unless it was done as part of a service and I do not recall. I will get it done now. Do you think I need to take it to dealer for any of these. I do know a decent mechanic, but I do not consider him a Prius expert or anything. Dealer will probably charge 500 $ per coolant change.
Phone them first and find out. Just from reports here I think you should be able to get out of there with both engine and inverter coolant changes, for around $400 USD. If you're considering DIY, have a look at attached. I've done our Gen 3, and it was straightforward, but not sure of gen 2 complexity. I do see mention of having to run pump via connection to OBD port, presumably requires Techstream, or some pricey aftermarket obd device, which is something I've got no clue about, nor the wherewithal to accomplish. Maybe gen 3 is easier in that regard.
I’ve booked in at my local Toyota for a 100k service, even though I’m on 142k almost… Seems certain maintenance has been missed. I’ve booked for engine oil and filter, coolants, hybrid health check, ATF change, pollen and air filters, brake fluid, alignment and hybrid health check. And of course the inspection too. At a cost of £400. This is all pre-MOT.
That's not bad at all: about $500 USD, $700 CDN. Maybe skip one of the Hybrid Health Checks... (The way you announced that, I could have sworn you were the OP, lol.)
What is " Hybrid Health Checks" ? Sounds like some visual inspection or charge money to do what they should be doing if you are loyal customer.
Health check is in Techstream terms reading active and history codes and sub codes. A 5 min scan. You can get hybrid codes too or read active data. However, it is difficult to predict hybrid battery health. The only other maintenance item would be to pull out and clean the throttle body and if you really have extra time clean the injectors.
It is a UK thing. The Hybrid Health Check (HHC) is essentially a check of the hybrid vehicle (HV) battery that is included in any intermediate or full service at a Toyota dealer. The HHC can also be purchased as a stand-alone service for £95, IIRC, but don't quote me. The big attraction is that it extends the hybrid warranty by a year each time up to (is it??) 15 years. The normal warranty on the hybrid finishes at the end of the tenth year in service.
