Oil change, brake and trans fluid interval for Prius Prime

Not a dealer, but...

 

Wow, thank you very much.

 

They might, or they might get sticky about copyright infringement.

I’m not sure what the minimum subscription is, something like $20 USD. The cost seems to pale, compared to the aggravation of getting through the interface on their website.

 

Looks like the same procedure as a gen4, but only takes 1.5 quarts? The gen4 takes ~3.5 quarts.

We use a 24-30 inch hose to fill from the top. Get a 10mm socket and a large breaker bar, because it's more than 37 Ft/lbs on those plugs coming out of the factory.

Hope this helps.

 

Probably is torqued to 37, but I know what you mean. FWIW prev gens were 29, and you needed extra long wrench for those.

oil change?

 

Oops, my bad. Those were the instructions for the rear transaxle for the AWD HEV.

Here are the correct ones for the Prime:
(follow the instructions for the PB12)
(there are four documents because the online manual uses hyperlinks)

 

Check my most recent post. I accidently gave you the instructions for the rear transaxle from the AWD HEV.

 

Got it.
And thanks again.

 

Since you have access to these, would you happen to have access to any pdfs of the toyota service directions for the gen5 prius prime front/rear disc brake calipers? You know, the procedures and proper torques in the course of any disassembly and/or things like changing the pads and lubing the slide pins. There are some decent guides on youtube, but I did not see any that include the proper torques for reassembly for this specific vehicle. Thanks again.

 

Looks like 79 ft lbs for the brake assembly bracket bolts, and 25 ft lbs for the caliper bolts.

 

Thanks for posting this!

 

I took my 2018 Prius Prime Adv in for routine oil change at 46,213 miles and they said that the transmission fluid should be changed at $269.00. I passed at the time since I was in a hurry but today I take in in for routine wheel rotation and balance and the Service Advisor told me I need the injectors cleaned, brake fluid changed and A/C condenser cleaned and inverter fluid changed. The inverter is supposed to be changed at 60,00 miles I find on the internet.
I asked him about the transmission fluid since I was contemplating a change and he said, 60,000 miles vs the previous visit that indicated it was in need of changing. This leads me to believe that some dealers push various services that are really unnecessary or in some cases premature. I have an in-ground storm shelter in my garage that I can drive the car over, crawl into the shelter and the car is level and I can do my own trans fluid change and that precisely is what I am considering at this time.

 

Changing the transaxle fluid yourself is definitely doable, and would save you probably over $200. A couple caveats/considerations.

• Review which plugs on the transaxle do what. The coolant drain plug is in a similar location, so if you're not wanting to change both, look to which one does what.
• For my car, I'd just use the ATF-WS, or the newer transaxle fluid, depending on what's recommended for your Prius type and year. These are available from the dealer's parts department. I wouldn't go for any aftermarket brand.
• Remove the fill plug first. This makes it so you don't get the drain plug out, but can't get the fill plug out. If my failing memory, and the fact that I've done this on a Gen 2 and Gen 3, but not a Gen 4 or Gen 5 is correct, the plugs are for a 10 mm allen hex bit socket (use a good one). If your allen socket, or the hex features in the plug round off, you can take it to the dealer. If you pull the drain plug, but then can't get the fill plug out...
• Stop by the hardware store, and pick up about 3' of tubing (take your fill plug to the hardware store so you can get tubing that's just a little smaller than the fill hole) a funnel (and maybe some duct tape to hold the two together). Alternately, the auto parts store has a hand pump for a quart bottle. The fill plug isn't located where you can pour the fluid into it. The only way to get the new fluid in is to thread the tubing in from the top (or pump it up from the bottom).

 

I think there's a gen 3 transaxle fluid change how-to link in my signature*, more-or-less identical to 4th gen. I'll attach the 4th gen repair manual instruction. It's a little more involved, basically more instructions to temporarily reinstall fill/drain plugs IIRC. A lot of rigamarole you can ignore. The main diff is higher torque values for both bolts, god knows why.

FWIW, Toyota USA (the entity the dealerships are supposed to listen to), says nothing about transaxle fluid changes. My 2 cents, change it at least once, sooner than later.
