Anyone have a full list of socket/wrench sizes needed* for the 2nd Gen?
 

*Needed for maintenance and common mods, mostly - if the big ends use an odd size external torx, that's interesting, but it probably won't affect me. I'd search the service manual, but I haven't found it.


Thanks

i don't think there was ever a list for the 1st gen.

8mm, 10mm, 12mm, 14mm, and up for more serious tasks
phillips screw drivers
e-torx bits

normally that covers the typical stuff. but all the sockets and every e-torx usually come in a set

Thanks. Do you know the largest external hex?

most everything that one would typically work on for fun or maintenance is covered with just the 8-14mm socket and phillips screwdrivers.

anything larger, or oddball like e-torx is stuff that they don't fully intend a typical person to get into.

so it really just depends on how far down the rabbit hole you're going.

Thanks - I wanted to check if external hex needs would be covered by a standard SAE/Metric set and it sounds like that's the case.

A good torque wrench will be helpful.

You mean I can't just eyeball the dyne-yards? ;)

i just go by ugga-dugga's.

biggest would be probably 32 on the axle

If you are gonna take out the axle you need a 19 for the lugs and 16 for the lca and trailing arm bolts, a good prybar and BFH.

You can be pretty sure that the car uses JIS Metric Standard for hardware (being a Japanese made car and all).

99% of things you do on the car, you will encounter the following:

• 10 mm, 12 mm, 14 mm, 17 mm, 19mm, 22mm (hex head bolts)

Not many components use hardware outside that range. Though, here are some exceptions that you will encounter if you will be taking on long term maintenance for the car:

• 32mm (Axle Nut)
• 10mm Allen Key/Hex Bit (Transmission & Differential drain bolts)

The car hasn't needed etorx bits since MY2017, when they changed the seat bolts to regular hex head


Shit kinda hits the fan when you start adding aftermarket parts. Companies vary where they get their hardware from, so the socket sizes will differ from JIS (usually ISO or DIN), sometimes even including SAE!


---------------

If you don't already have a toolkit, I recommend the Harbor Freight 301 pc Mechanic's set (especially right now that Harbor Freight has a 25% off any single item coupon!).

It has practically everything on the above list and then some, with almost no missing pieces, and a bunch of other handy stuff to have.

I bought one when I first started wrenching, and haven't needed to add much to it other than specialty and quality-of-life type tools. The single exception is that it's missing a 14mm combo wrench, but that's easy to add.

Thanks for the detailed reply. I have a good socket set, but, like most, it tops out at 19mm, so I was curious what I might encounter outside of that range. Is there a practical difference between JIS Metric Standard fasteners and other metric standard fasteners? I presume the size difference in head is axial, meaning there's less material and a greater risk of rounding, for a given alloy? If so, good thing I have six-point sockets...

The fastener/bolt strength grades are the same as ISO and DIN (Metric strength grades). I personally prefer the smaller heads; makes access easier. But you can round any fastener with enough force (or without enough care).
The practical difference is that in the JIS standard, there is a specific table linking bolt diameter to both socket size and pitch. There are a few exceptions on the car proper, but generally you don't have to guess at a fastener.

• If you know what socket fits on a piece of hardware, you can easily find on a table what the thread diameter and pitch are.
• Alternatively, if you measure the bolt diameter, you can know with good confidence the thread pitch (and not have to guess at whether it's coarse, fine, or superfine) and what size socket you will need for the job.
