Hello everyone. I bought a 2015 gen 3 Prius, trim level 5. It's in extremely good cosmetic shape, but with high mileage. Bought at 160k, now at 180k. No engine lights. I changed the transmission fluid, which had clearly never been done. It was dark, but smelled oily, no burned smell at all. Seems fine after changing. Otherwise, I've changed the plugs, air filter, cabin filter, battery filter. Oil changed every 5k miles. I am planning on tackling the EGR valve and exhaust manifold in a couple of months when we'll be able to park the car for a couple of days. I don't want to do this job under time pressure as this is our only vehicle. The splash cover under the engine is pretty warn. I tried to unbolt it but the bolts are rusted and broke off. So I have bought another splash cover and plan on replacing it and drilling the remaining bolts out if they break. (not sure if there's a better way to remove the bolts since I'll be stripping the threads when I drill them out.?) My plans are to change the inverter coolant and the PCV valve when I put on the new splash cover. Otherwise, I'm planning to clean the AC evaporator. Is there anything else I need to do while I'm under there? Thanks to all who reply!
there are a lot of things that should have been done by that mileage. do you know the maintenance history?
No. That's the problem. When I did the transmission fluid, it was obvious it had never been done. So I'm assuming they did very little other than oil changes. I'm doing the water pump up top soon. knocking out the little things where I don't have to get too far into the car. Plan to clean the battery fan next week, ordered a scanner and Dr. Prius.
Yes, I mean intake manifold. Thanks for your suggestion. Too bad I can't get a guy like you to help me for beer .
go to toyota.com/owners and plug in the vin. any dealer maintenance will be in there. whatever you don't see, i would complete from the maintenance schedule also on the website. when you get to the end of the schedule, start over from the beginning, except for anything which has a shorter interval after the intial service. i think coolant might fall in there. and get your parts from a dealer source, there are a lot of really badly made counterfeits flooding the aftermarket
Definitely better to take an organized approach At the moment, I'm doing anything easy, because nothing was done. I buy better parts, only if they are actual OEM with many reviews of satisfied customers. Engine isn't using any oil at all. For that matter, it's using no other fluids either. Changing at oil at 5k now, it's staying amazingly clean. So I think thus far I've got a shot to turn this around. We're buying a new car in the next couple of months and then I can take a few days and do things like change the EGR/clean intake manifold. At the moment we've got to drive every day, so I'm limited in what I can do. It's complicated as well by me with 10 thumbs all pointing in different directions.
