Hello everyone, I am around 103k miles and had a few maintenance questions. Do I have to change the inverter coolant and engine coolant only at Toyota? Can I change the engine coolant at a smaller shop and inverter coolant at Toyota? (I assume the shop would not be using Toyota’s coolant) Why am I quoted $300 at Toyota to change fluids that take less than an hour to drain and fill? (Fluid is only $50, $250 doesn’t justify 1 hour of labor) I’m changing my spark plugs with aftermarket ones from AutoZone, will this lower my MPG? Lastly, what are the risks involved changing the inverter coolant and engine coolant my self? (I would be purchasing the coolant from Toyota)
100,000 miles or 120 months Check installation of driver’s floor mat Inspect and adjust all fluid levels Replace engine oil and oil filter Replace engine/inverter coolant Rotate tires Visually inspect brake linings/drums and brake pads/discs Your manual says “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with long-life hybrid organic acid technology. So it does not have to be Toyota fluid, but they are pretty stringent on what it should be. Toyota Fluid is available on Amazon, or your Dealer's parts counter. www.amazon.com/Toyota-Scion-Coolant-Antifreeze-Genuine-00272SLLC2/dp/B018Y2WQRK Tight working space and care to get all the air bubbles out are the major issues with DIY.

Good idea to change the inverter coolant pump while you have the coolant out. They don't last forever, and will kill the inverter when they go bad. Brake fluid if you haven't done it. three years, and then every two.
Just had my 100k service done... my dealership tried to tell me that my rear brake shoes needed adjusting and cleaned... they tried that at 50k miles too. I laughed, threw the car in reverse and let the auto-adjusters do their thing.
