I own a 2014.5 Toyota Camry Hybrid (XV50 produced for Camry model years 2012 to 2017) and was shocked when Toyota of Santa Monica wanted $752 (plus tax) to clean the hybrid battery cooling fan intake system. I'm a former Master Star Certified Mercedes-Benz Technician and I felt that was beyond excessive so I did some digging. It was neither difficult nor time-consuming. I haven't found any videos how to do this on anything other than a Prius. So why doesn't one of the world's most popular vehicles have a video? Let's change that.
This is Video 1 of a 4 part series that exposes how a dealership takes advantage of their consumers.

Tools Needed:
Torque wrench (3/8 drive)
12mm socket (3/8 drive)
6 inch extension (3/8 drive)
3/8 ratchet driver
Small flathead screwdrier
Vacuum cleaner with a nook/cranny attachment
Patience
Empty wallet

Flat Rate / Flagged hours / Book time:
If the manufacturer says that it should take you 3 hours to perform a repair/task, they will pay you for 3 hours of labor at your hourly wage. If you complete that task in 1 hour, you get paid for 3 hours of work at your hourly wage (I've flagged over 24 hours in a single 8hr workday). If you complete that task in 6 hours, get paid for 3 hours of work at your hourly wage (I've also had really slow weeks where a 40 hour workweek would only see 24 hours to my paycheck).
Service Advisors get paid on a variety of goals. One bonus is based upon the total number of technician hours they sell. Example: $1 per flagged hour. 1 technician flags 50hrs in a week. Team of 4 technicians = $200 bonus for a week. They might also get a % of the parts cost. It all depends upon whatever contract the dealership makes with the advisor.

I used to work at Mercedes-Benz dealerships as a Master Certified Tech. I've seen family-owned and big corporate-owned policies. When it's seasonally slow, techs are encouraged to upsell repairs that may not be needed. That's understandable. I do not stand for unfair pricing and I do not stand for subpar diagnostics. My job was diagnosing and fixing everything on the car from the front bumper to the rear bumper. My managers would also give me someone else's car that's been in multiple times for the same problem and even the cars that are in litigation for lemon-law buyback. Diagnose, document findings, report if the technician did a good job and attempt a final repair. I'd advocate for the tech, I'd advocate for the customer, I'd advocate for truth, search for answers, give honest answers and not compromise my integrity or honesty if I was low on funds or hours.
