Looking for instructions on 2017 Prius 4 coolants flush/change

IIRC Toyota USA says 100k miles (or 10 years) for engine coolant, 150k (or 15 years) for inverter coolant, and 50k miles (or 5 years) for both thereafter. FWIW, Toyota Canada says 100k miles (or 10 years) for both.

I’ll post a spreadsheet summary of US schedule in a bit. <Done

Attached are repair manual excerpts for both changes.

 

$680????? HOLY CRAP! I called my dealer for price on just a drain and fill transmission fluid...$315!

I changed all fluids in my wife's 2017 last summer....unbelievably easy. Hardest part was refilling the transmission (I hate those little pump bottles...always ends up making a mess.) So, instead, I used a 3-foot tube I held above the engine bay and my wife watched underneath and told me when it was leaking out...put a new gasket on the drain/fill bolts, and done.

I change transmission fluid and coolant on our cars/trucks every 50,000 miles or 5-years.

 

Did the same thing, 'cept I was downstairs...

Didn't even consider a pump; funnel and hose is as reliable as gravity.
