Hi everyone The official dealer offered a service at 90k worth more than $ 1000. After I removed all unnecessary options, 400+ came out. As I understood the main thing is the replacement of engine oil and transmission, replacement inverter coolant. what else? what to els? Of course I will replace the air filter Perhaps there is already not one similar topic, but I have not found it. excuse me)
welcome! you don't change the inverter coolant at 90k follow the maintenance schedule toyota provided with your car 90k = oil and filter check/clean/replace air and cabin filter tires rotation total inspection and brake lubrication consider tranny fluid swap engine shaking at idle might be throttle body or maf sensor
Look in the glove box for the Toyota USA Warranty and Maintenance Booklet, it outlines what needs doing. You can also download a pdf, from Toyota Tech Info (the manuals section), for one. Page grab from page 49: The highlighted ones are what's crucial.
^ Addendum to the above: The brake inspection also is important. It's the third in-depth brake inspection spec'd by Toyota (every 30K miles); at other intervals it's just "visually inspect", basically just a look-over during tire rotations. And of course, dealership said nothing about brake inspection???
There is zero need to measure rotor runout or rotor thickness if the brakes are working fine, especially on these cars. Asian vehicles which use an adhesive friction system do not wear the rotors very much at all. If the brakes are working normally with no vibration, the runout is low enough that it is not causing disc thickness variation. The only time you need to measure rotor runout is when doing a brake job. @Raytheeagle is now an expert at it.
I guess we’ll put my “expertise” to the test next weekend. The brake job is required on this old corolla: Hopefully I’ll look as professional performing the task:
