So since I saw this posted earlier I figured it might be worth starting a general maintenance thread for the community (thanks @Jeonsa
Please please please keep this MAINTENANCE RELATED! I don’t want this getting derailed.

I know that for my Supra (mid Covid of course) there was a shortage of “Supra oil” as well as things like differential oils, gear oils, etc were all typically backordered a few months out.
If you Happen to have part numbers, I know at least a few employees or former employees are on here maybe they can provide part numbers for the oils and any future maintenance stuff that we potentially run into as the platform expands.

Our cars DO NOT TAKE THE SUPRA OIL, please refer to your manual for API specs.

 

Yup just being upfront, if anything gets off topic the comment will get deleted. This thread will be pretty important going forward, helping the community.

 

@ijuswannaride any chance you know part numbers for the diff fluid and gear oils? I wanna add it to this thread.

 

No. At our dealership we bought all gear oil in bulk, no little bottles in the parts department. We bought bulk gear oil that met Toyota specifications from a Toyota approved distributor. Same as our 0w20 oil. We had bottles in the parts department to sell to customers over the counter, but in the shop we had reels that hung from the ceiling and dispensed bulk oil which is a fraction of the price of the bottles. During my days as manager, I'm actually the one who set it up so we could get the 0w20 in bulk. It was less than half the price of the bottles. The specs for the trans, transfer, and differentials are pretty clearly laid out in the owner's manual. You should be able to buy that stuff at any auto parts store.

 

of course I referenced the owners manual

transmission p/n 08885-81001
transfer p/n 08885-02506
differential p/n 08885-02606

 

PIN IT please!

 

Note that the manual says "or equivalent" for each one of those. Go to the auto parts store.

 

agree, but figured I'd let people decide on their own.

 

The standard Toyota 0w-20 is API SP, and as far as the manual says, it’s what our cars use, do you have a PN for the oil you think we require?

 

So if you look at the 0w-20 in a toyota bottle it is made by Mobile 1. I have used Mobile 1 in all my Toyotas and even my Honda Sport bike and have never had a single issue. If you have a Costco near by every couple of months they will have it on sale for $35 a case of 6 quart bottles.

 

The engine oil is just standard 0w20 SP rating. Available at any Walmart etc.

 

For those of you doing the oil change yourself, how easy is it? Oil changes on my GTI are surprisingly easy for a German vehicle.

Edit: and to be clear, by "easy" I'm referring to the filter or oil drain plug being in weird AF places, needing to take off a skid plate/splash guard, etc.

 

highlighted is all that matters for oil.

whether you're doing it yourself, or having it done, just make sure that grade is going in. viscosity may change depending on application and region.

note it doesn't say recommended next to the oil grade, only for viscosity.

 

Hello attached is a scanned PDF for the complete maintenance guide taken from the car.
If this has already been uploaded then mods can delete this post. But I am assuming this would be the place to drop it in order for my fellow GR owners to refer to it moving forward.

This guide includes the scanned pages from 1250 miles to 115k miles.

 

That pdf has everything? Brakes(bleeding and pads) diff alignment transfer and different

 

Here are the alignment specifications and procedures for the GR Corolla. Note this includes all the other Corolla models. The reference to G16E-GTS is the GR Corolla.

 

And, it gives the part numbers for the camber bolts for the front which someone here was looking for the other day. 👍

 

Does Toyota sell factory service manuals to the public, or is there another way to get one?

 

I don't know if you can still order them, but they're crazy expensive.

 

I had posted this on another page, but turns out there's already a maintenance sub. Here's every fluid info on the entire car.

All part numbers for services and technical tidbits:

Oil filter (factory fit - only available in Japan) : 90915-10009
Oil filter (North America equivalent) : 90915-YZZM1 = 90915-YZZF2 = 90915-YZZN1 - all three supercede to the newest N1, some dealers may still have old stock as this is not a fast mover.
Oil filter (unconfirmed alternative bigger filter): 90915-YZZF1 - this is a common upgrade for 4A-GE's. Stock 4A-GE filter is the YZZF2 filter, but YZZF1 fits, longer by about 1cm = more filtering. Only limitation is fitment of the longer filter.

Drain plug gasket for engine: 90430-12031 - M12 double teflon coated aluminum
Rear diff drain and fill gaskets: 12157-10010 x2 - M18 ring/donut type
Transfer drain and fill gaskets: 12157-10010 x2
Transmission drain and fill gaskets: 90430-18008 or 90430-A0003 x2 - M18 aluminum flat
For what its worth, both Rear and Transfer drain plugs are magnet equipped. Both are 90341-18051, no need to replace every service.

Transmission oil: 08885-81007 x2 Toyota LV (w/LSD is 2L, but w/o LSD takes 2.1L, so might need more than 2)
Rear diff oil: 08885-02606 Toyota LX (half ish liter)
Transfer oil: 08885-02506 Toyota LT (half ish liter)

Oil (factory fill): 08880-13205 (4L can, you need more than one, spec is 4.3L with filter change)
Oil (Canada): C0BBA-0W2SN-1J (4.4L, API SP, which matches the ILSAC GF-6A req: Oil Categories)
Oil (USA): 00279-0WQTE-6S (per quart) - this part number was also used for API SN Plus, but it should now be all API SP. Back of the bottle says if it is.

Here's the full service specs from Toyota docs:

What is the correct one for transmission gear oil? I saw someone else posted 08885-81001

 

oil change procedures

 

spark plug replacement procedures

 

transfer oil replacement procedures

 

transmission oil replacement procedures

this is for transfer

 

12v battery replacement. note the vent hose.

 

I'd like to add, always crack loose the filler first. you loosen the drain first and can't loosen the filler, is not a good place to be.

 

brake fluid replacement. note the DOT4 fluid is recommended.

 

differential oil replacement

 

transmission oil replacement

 

front and rear brake pad change

 

map light

 

vanity light

 

room light

 

I dunno if thank you will suffice for all of these... any chance you have coolant flush and brake bleeding? might as well ask for the moon 😝
