This vehicle has SUPER LONG LIFE COOLANT.Don't trust the users manual when it come to intervals?
Coolant change should be done every 60K miles (flush).
Fluids (ATF, gear oils) every 30K miles (flush).
Brake fluid every 2 yrs/30K miles (flush).
Engine oil every 6 months/5000 miles.
PS flush every 30K miles (flush).
This is what I follow with my vehicles and it has rewarded me handsomely with low maintenence costs over the years.
Well stated :tu:100k miles is just fine as the the Toyota Interval suggests. I trust Toyotas recomendations 99% of the time. But may be tailored to suit extreme conditions. I check my cooloant with a coolant testor over the years. The coolant properties never go bad over the miles unless yu dilute it with water and other stuff:td: . It just gets dirty with sediment and cloudy. That's why it generally needs to be changed at the correct intervals..
The pink is the O/E fill. Of course if yu need to do other radiator, thermostat, hose replacements etc. And one needs to drain antifreeze coolant in the process, then I would refill with new Super long life Pink.
Toyota in years past allowed for 60K intervals with the Long Life Red.
It has been superseded currently on all new Toys and Lexus'.
