Hello everyone! Welcome to @autoscholarwithmrb! Today we have this 2010 Toyota Prius, Generation 3, and we are going to clean the battery cooling fan. This car just had the high voltage battery replaced with a refurbished unit, and is in for other work (brake actuator, check engine light). I asked the owner if the car has ever had the fan cleaned, and he didn't know, so I decided to take a look. IT WAS DIRTY, but not the worst I have seen.
Cleaning the fan isn't something that Toyota considers a maintenance item, but as you can see, they do get dirty and can cause issues. This job takes about an hour to do and requires minimum tools. Trim tools, a 10mm socket, and a source of compressed air or a brush is all it takes to do this.
Make sure your battery lives a long time, by ensuring the fan is working as well as it can!

If you're gonna spend the time to get this fan out, you may as well clean it 100%.. i discovered there are only 3 screws (and 2 clip-like holders on the bottom) holding the two sides of the fan together! Just take it apart to easily get to the squirrel cage. You can even separate the cage from the shaft, although I totally cleaned the fins with it together before discovering this easy trick. You can totally clean out the inside of the fan housing as well. 100% clean!

Thank you for sharing this important information!

I find it so laughable that "all you need to do is..." (then proceed to insert a dozen - or more - steps). I really appreciate your video!! It's so crazy how much you need to take apart to get to not only THIS fan, but many other things on the Prius. It's like a big snap-together toy.

Just did it ..bout an hour...108k on a 2010 ...wasn't too dirty but I was glad I did it.I also have a fine vent cover . I did notice that the exhaust vent empties into a dead space near the spare tire...I couldn't tell if there is any resistance to air flow where it empties out but I hope not!!

Leave it to engineers to make something that should be easy to service time consuming.

Hi , my Prius gen3 poped an error check hybrid system, I tried checking if the fan works by putting a paper on the inlet ( my Prius had no filter behind it) I felt no suction and do not hear the fan spin ) is the fan suppose to be always working when the car is started ? Even if one of the hv battery modules is faulty ? I'm asking to understand if I have found the problem which is that the fan no working so the battery down for safety.

@angelcarrillo980 Год назад

I think you broke the fan. Mine is dirty, but still spins.

@Akcios_Aron 4 месяца назад

The fan only starts when the battery requires it. It doesn't always work.

@41708 9 месяцев назад

Good stuff, but where is the fan inlet filter and how do you clean it? for 2009 model if possible Many thanks.

@simplyraw1369 7 месяцев назад

Ya know I too was wondering about the HV "filter". I had my 2012 at the dealer and was told I needed to have the HV filter cleaned for a whooping $175. I thought to myself to clean a f'in filter you want $175?!! No way... Went home then to the Toyota website parts plugged in my vin number and there isn't even a "HV BATTERY Filter" that fits my car shows some for newer cars like 2016 up but not for 2012. So I am assuming there is NOT A FILTER ITS JUST THE FAN BLADES THAT GET CLEANED. which I wonder if they would have actually charged for a damn filter too IF I had it done! Stating that I needed to clean something where I don't believe that this car even has, it's deceiving. I get that the fan needs cleaned but just say that then. I will do this myself *probably will need to have some of them dang plastic clips on hand I seem to always break them things 😂.

@@simplyraw1369 I haven't bought one yet but I'm amazed at how many extra things, expensive items, can go wrong on a Prius. Mechanics around Sarasota charge $125 an hour and up. Engineers must stay up nights designing ways to make it difficult. That fan should be a simple pull out and clean and plug it back in.

@betht5395 Год назад

Toyota dealership estimate is $300 + for this service. Is this the usual charge every where else?

@justonemori Год назад

If my jackass can do it in two hours of screwin around they can do it in half. This is a pretty easy DIY since all you need is a screwdriver and a 10mm socket on a ratchet with an extension. New fans are $200 which is expensive for what it is but imagine paying the additional $300 for dealership labor making it a $500 bill. Yikes!

@iamkarlwithak Год назад

I had this done 15k ago and the wrench warning light has come back on. The dealer said I should be good for another 75k. If I do this myself, will the light reset? How do I reset the warning light?

@Akcios_Aron 4 месяца назад

You need to remove the fault code from the computer with a diagnostic tool.

@hyeeagle Год назад

You forgot to show how to clean ( shop air it’s not clean,clean ).

@DavidMutaleMwilaPhiri 20 дней назад

does the fan need to start running when you start the engine?

@AutoScholarwithMrB 20 дней назад

No, it only runs when the battery gets too warm or two cold

@pragmatic_mystic1675 Год назад

We just did this and “Check Hybrid System “ warning comes on and the car doesn’t go. Any advice on how to clear this?

Did you put the orange plug back in correctly?

Dear Mr B. and other viewers, I have a question about cleaning the HV battery cooling fan on a European Prius Plus Wagon (2012). The Prius Plus Wagon is sold in the US under the name Prius V. But..., there is one big difference when it comes to the spot where the HV battery is located in the car. In the European Prius Plus this HV battery is placed between the front seats. On the US model Prius V Wagon the battery is placed under the back seat row. From the outside the Prius V and the Prius Plus (Europe) look the same. Both are wagons. However, the European model has THREE seat rows. The European model is a SEVEN seater. The location of the HV battery is therefore very different. Like I said, it's between the two front seats. Would anyone know where to find information on the cleaning procedure for the battery cooling fan the European model Prius Plus Wagon? I could not find anything on RU-vid. The air intake for the battery cooling fan seems to be under the right front seat for the Prius Plus. Are there Toyota service manuals for car technicians who cover this cleaning procedure? Thank you all in advance for your help, M

@hyeeagle Год назад

Just fallow the P-FAN air intake duct find that P-FAN motor take it out and clean the way in the video he explain. You don’t need instruction. Even Toyota factory book doesn’t explain well.

@jimdrums4life499 11 месяцев назад

Welp, i shouldve learned by now not to listen to YT mechanics' quick easy fixes. This was a huge pia, due to all the clips (there were about 5 more than in your video). Plugged everything in, put the orange plug in.... Now the 'Check hybrid system' lights are on. Scary, but posted how to reset the system below.

@AutoScholarwithMrB 11 месяцев назад

Do you have the orange plug all the way in?

@jimdrums4life499 11 месяцев назад

Yes. I, watched ANOTHER YT fix video (lmfao) and reset the system pulling the orange plug and the white wire under hood. She should be ok. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-37xcB5GlPf8.html

@joeshmoe8952 Год назад

How often should the fan be cleaned out?

@AutoScholarwithMrB Год назад

Hard to say, because it is dependent on the environment. I would say check every 75k miles or so. Thanks for watching!

@joeshmoe8952 Год назад

@@AutoScholarwithMrB Cool, thanks for the info.

@hyeeagle Год назад

It depend how much dirty you keep p-fan area. If you keep just like that car he showing you may need to clean every month. If your car is super clean all the time I would say every other years or more

@OMGitsdiane 9 месяцев назад

How are you supposed to unplug the fan? I got that far into it and wasn’t able to unplug it 😭😭😭

@AutoScholarwithMrB 9 месяцев назад

Should be a tab you push in and pull out

@OMGitsdiane 9 месяцев назад

I was able to remove it today, however the check hybrid system message is on now so I must’ve messed something else up. Do you know what could be the problem?
