90k-100k services, right part numbers?

If you supply your VIN number when you are putting in your order, the system will verify that you have the correct part numbers. I presume that you are visiting a dealer for the ATF and coolant -- as far as I know, none of the online sellers will ship fluids. Check with your dealer to see if your car falls under the inverter cooling pump recall. That will give you a free coolant exchange in that part. Be sure that you understand how to refill the coolant heat storage tank before you drain it, and read up on bleeding air out of the system as well. Same goes for bleeding air out the inverter cooling pump system. Lots of threads here on these procedures. If either system air locks, then you will get triangle malfunction codes. Check carefully the area around the engine water pump for signs of weeping. If you see pink residue particularly on top of the A/C compressor, then the water pump should be changed in addition to servicing the engine coolant.

 

Thats alot of work for one day. Not sure where all your gaskets come from. I have done most listed myself on my 07 also:

Oil change
Takes 3.5 quarts with a new filter. No more
PN is correct for filter
No gasket needed. But if high miles get a new
bolt for the pan. Its sacrificial like most pan bolts.

ATF 4 qrts WS Fluid
No gasket needed but get new washer for the dump bolt.

Inverter Coolant
I gallon SLLC. No gasket needed.

Engine Coolant
4 gallons SLLC No gasket needed.
Have never down this myself but would not attempt without a Highlift
Airlock Vac Purge. Air Locks are very hard to get out of modern cars.
And without a highlift you will never have 100% confidence all the air is out of the system.

 

I think here gaskets == crush washers. On my RAV, I still have the same oil pan crush washer going on 30+ changes. But there's no knock on being conservative with the coolant and ATF crush washers, since opening a drain back up to fix a leak can undo quite a bit of work.
