I have a 2008 Prius with about 97k miles.......I am about to take a 4k+ mile trip. What do I need to have looked at/done/checked?....Thanks.
Lets assume you have done nothing but motor oil, oil filters, and air filters so far. Change the transaxle, with new ATF WS and two gaskets. New coolant in both the engine loop, and inverter loop.
Also, check your wiper blades and tires and replace as needed. Make sure your spare tire is inflated to 60 psi. Replace the serpentine drive belt and PCV valve. Check the front struts and rear shocks and replace if needed.
