Diagram to reach hybrid battery fan?

When I changed out my satellite antenna and amp, I had to get down to the area where the fan is located, directly to the right of the HV battery. Not all that easy with a lot of panels to remove. I have attached a pic of my 2012 v where you can see the fan. It is the white round shape bottom left corner. I have also attached a video link where a gen 3 Prius (standard) has the fan removed. It appears to be about the same setup.

The video suggests that Gen 3 battery fans don't usually get as dirty as earlier Gen 2 fans, plus a trouble code will occur if it is bad.

Still, the best solution might be to get a weekend subscription to TIS and then download the specific instructions. One caution on that route; often Toyota will have you remove more than absolutely is necessary to make access easier. Maybe someone already has a good video on specifically on the v.

This one page Toyota doc, T-SB-0162-13 has links to the paid removal procedures in TIS. You will have to get a day or weekend subscription to TIS, find this doc and then link to the procedures. https://www.carmd.com/Tsb/Download/101603/T-SB-0162-13

Note these cautions about cleaning the fan:
• Do NOT attempt to clean the HV Battery Cooling Fan while it is installed in the vehicle. Doing so may cause dust or debris to enter the HV Battery Case.
• Failure to secure the fan blades while cleaning can result in electronic circuit failure due to overturning.

Also if you want to see what was necessary to remove the antenna amp see the pdf in post 10 of this thread: Prius v Antenna XM Satellite Fading | PriusChat

 

I just hopped in, it's not that hard. Don't do any more removal than needed. For example: the third Gen video shows rear seat removal, which is not necessary. Also, the fan can likely be cleaned without needing to be pulled right out. A Q-Tip works well. Also clean ductwork. Compressed air helps, just avoid over-spinning the fan blades, hold with a finger while blowing.

 

There's a carpet fastener near the ductwork you can remove to roll the carpet back making the job easier. I removed the rear seats when I cleaned mine allowing easy access and also allowing the seats and carpet to be thoroughly cleaned.

 

With the Q-tip method, you're going to need a lot of Q-tips. I also recommend a 12-year old with some free time for the labor.

 

I used one.

Wasn't that bad, and I blew it out with air first too.

 

I also used compressed air but it took a ton of Q-tips. When my son pulled the blackened Q-tip out of the blade I told him not re-use them. Luckily Q-tips are cheap. At least they were the last time I bought which I'm pretty sure was during the previous millennium.

 

Yeah, apples 'n oranges. Our west coast air is a lot cleaner I think, near nil carbon particulate. Plus we're really low miles.

 

All good info above - thanks.

I did this today on my 2012 v with ~54k miles. Turns out for me it was not worth doing. There was hardly any dust at all. But I did everything anyway ... removed motor, q-tips, etc. It was definitely the first time this was done on my car, and still very clean.

 

I looked at mine again around 200k miles. No dirt. I think it is a function of how clean you keep the car and if you transport pets.
