Yes it is…the speakers cover up the three screws on each side that hold in the battery.
Very nice guide, and the plastic alignment jig in the replacement battery was great!
I did find I was missing some of the bits promised in the repair kit. I pulled out my generic Apple toolkit I’d bought a few years back, but was missing the driver for the six tiny screws holding down the main battery. A tiny flat blade fit and I was able to get them out. I then pulled out the syringe for the acetone….why is it clinking? Syringes don’t clink….and there were the missing bits, slipped inside the handle of the syringe during shipment!
My wife's MacBook has been overheating for some time, and then shutting itself down. Your instructions were great, but I did note that I needed to unscrew the cable tie near the speaker in Step 17.
The system had some dust in it, used the air can to spray it all out. Dust was on the heatsink vents, too. Closed it all up, and peak temps during a software install that crashed it three times yesterday was 145F - yesterday it was passing 170F and crashing.
Thanks for the instructions, ifixit!
