I purchased my second Prius this past week, a 2019 Prius 2. It was a one owner with 140,000 MI. It's a world of difference from my 2008 Touring. Do the same minor tune-up tasks also work for a 4th Gen Prius? Things like mass airflow, throttle body cleaning, engine air filter, religious oil changes, eCVT coolant replacement, and spark plugs? The car did not come with any books. Thank you.
congrats, sounds like a beauty! yes, still a gas engine, all the same maintenance. if you don't know the history, I would change all the fluids and filters, and have the 12v load tested. all the best!
Owner's Manual and Warranty and Maintenance Booklet can be downloaded in pdf format. One source TechInfo Toyota, under the "Manuals" Tab. If you don't relish wading through the event-by-event format that maintenance is outlined in the latter booklet, see attached, table format summary, faithful to the booklet, and an extrapolated version, to 24 years or 240k miles. Not mentioned by Toyota USA, but worth: brake and transaxle fluid changes, throttle body cleaning.
Congrats! We love our 2017 and 2021 Prius (Priis??) This is my maintenance schedule for our Hybrids: -Oil/Filter Every 6-months or 5,000 miles (whichever comes first) -Air Filter As Needed (check every 6-months) -Cabin Air Every 12-months (Charcoal) -Hybrid Air Filter Cleaned Every Year - Radiator Coolant Every 5-years or 50,000 miles -Hybrid Coolant Every 5-years or 50,000 miles -CVT/AT Tranny Every 5-years or 50,000 miles -Spark Plugs/PCV and PCV Valve Hose/ Radiator Cap / Gas cap Every 10-years/100,000 Miles -Brake Fluid Flushed Every 4-years/50,000 miles -Throttle Body Cleaned Every 25,000 Miles - MAF Sensor Cleaned Every 25,000 Miles -Tire Rotation Every 5,000 Miles
Thank you for these references. I had quickly searched for the throttle body and it's not as quick to access, as it is on the Gen 2 s. I really like that they specifically made removable plastic to allow top access to the spark plugs Thank you so much for these references. I like that they made a removable plastic for spark plug access. The throttle body looks a little more challenging, just need a little patience.
They're all e-books now. I would recommend an ATF change; to refresh and dump out any crud formation over the last 140K miles. I would also recommend that you get an OBD2 HUD unit; so you can monitor your ECT. Those electronic water pumps tends to get lazy after around 150K miles. Better to catch that issue early and replace it - than to wait for an overheat and possibly a head gasket issue. Good Luck..... PS; my personnel opinion on that MAF is to leave it alone. I believe spraying caustic chemicals at it would more likely break it, than help it.
I was not aware that their existed and OBD2 heads up display. Got a reference for one that speaks hybrid? Thank you
