    Hi everyone,

    I was recently at Elmore Toyota in Westminster, bringing in my 2017 Prime for a routine maintenance & oil change service. Before my car was taken in for maintenance, the service advisor looks at my car's records and says they recommend a hv battery fan & some other coolant flush service. I respectfully declined before they took my car in. After about an hour, the tech finished my car. The service advisor says the tech saw my hv cooling fans were dirty and that i need inverter coolant exchange.

    How can I check myself if my Prime really does need this? I honestly feel like the service advisor is trying to squeeze more revenue since the dealership and service department was like a ghost town when i went during this Covid-19 stuff. I don't know how the tech can know if the hv fan is dirty since he needs to take apart the whole back seat I believe which i'm pretty sure he didn't do. I have items in the back seat area and they were pretty much in the same place when I took my car back. Any advice or instructions on how I can check these service recommendations myself will be greatly appreciated.

    Stay safe everyone.

    You should be able to check your hybrid battery fan yourself. Not sure of the details, other Prime owners will hopefully have tips.

    A dealership recommending to change coolant on a 2017 with 60k miles should be avoided. And reported to Toyota.

    Check your Warranty and Maintenance Booklet for what maintenance is due, and when.

    Piece of cake! Pull out the cargo mat. Take out the lid on the little cable storage bin by the hatch latch. Remove a few plastid fasteners and lift the deck out. It takes about three minutes if the cargo area isn't loaded with stuff like mine. The fans will be staring you in the face.

    If you want to continue with the same dealership, just decline all services they suggest.

    Look your manual to see what is technically needed/necessary.

    While some of us here disagree on proper service and maintenance for vehicles...the SA was just trying to pad your bill because he makes a cut/commision doing so. I guarantee the Mechanic/Tech said NOTHING about your fan needing cleaning. They just read the W/O and do the job assigned. Period. They are already to busy to go fishing for more work.

    What's the trick to removing those 4 plastic fasteners? One of mine is missing all together. They look like buttons. Need a special tool? Thanks. Ted

    Just a slot head screw driver will do. Even a butter knive (an old one the wife won't miss)

    Small screwdriver. Two, one on each side is easier. Easiest is a paint can opener.

    Just use whichever tool to pop the center part up an then the whole thing comes out. Just like the panels under the car or the ones under the hood.

    I'd be suspicious of this service center.
    Funny how these extra services, beyond routine maintenance always seem to manifest sometime after the end of the Toyotacare period.

    I think in situations like this, your gut feeling isn't too bad to follow.
    I think I'd just be looking for a different service center for future maintenance.

    Did you take off the panels at the right and left sides? It'll also help to take out the cable storage bin that's between the bumper and the battery. It will need a 10mm socket.

    @tedjohnson you also need to remove the plastic compartment just inside the hatch to see the fan and ducting. The plastic compartment where the EVSE-charger cable and the tire lug tools were stored from the factory. The fan is under that plastic piece. Just pull it up gently after removing the other pieces mentioned above.
    And when removing the cargo area floor just on top of the traction pack make sure to pull it straight back towards the bumper an inch or two before trying to lift it out of the cargo area.
