Winter tires and wheels? Acquired.

Upper radiator block? Installed.

Washer fluid? Swapped to -25C 'illegal to sell in California' fluid.

Windows/headlight lenses? Washed the outside with 90% rubbing alchohol.

Now... to wait for first snowfall for stage 2, putting the winter tires/wheels on, the lower radiator block, and winter oil change with fresh 0W-20 oil.

And somewhere in there, swing by the dealership and pick up the replacement wiring harness sockets, and pick up some black car silicone taillight sealant so I can re-wire my import LED brakelights to US sockets and install them with full weather sealing. Also need to swing by that paint-and-body shop, get a quote on them re-spraying the chrome sections of the tails to body colour silver instead.
