Maybe you will be the first. :madgrin:

 

Cover with a leg section of panty hose?



Just a trial, will take it off for now. Kind of wondering how much a fine mesh like this is reducing air flow. Perhaps someone with engineering background could comment?

Also, my wife's comment: more coordinated color might be in order

 

I can't give you a number, but a lot. probably by 50% or more.

Hold your hand a few inches from your mouth and blow on it. Note how it feels. Hold your hand on the other side of a layer of panty hose 1/2 way between your mouth and hand at the same total distance and blow through them onto your hand. The reduction in airflow is remarkable.

Whether that amount of restriction is a problem or not depends on how much reserve capacity Toyota built into the cooling fan.

 

That was my hunch, just trying to breath through it. Hmm, ok, thanks.

 

Just rummaging a bit: I've found some vacuum motor filter material, 1/8" thick, fairly open, looks like a miniature furnace filter. Seems very low resistance to flow. Popped it in behind the grill, will see how it goes.

 

Was thinking of the economy grade furnace or air conditioning filter material from Home Depot. Will be trying it out.

 

With added heat exit tubes flow of air is fine even with a screen filter set in behind air grid . Fan hardly ever has to come on anymore... when it's hot outside air conditioning helps to minimize fan need also. That's with one 3/4" tube at top middle of pack flowing out to driver's side rear vent and old venting tubes twisted with about 2/3 eds of holes out. Though center sensor tends to be about 4 or 5 degrees higher the whole pack is staying much cooler usually below 100 F.

 

Soon thereafter I decided discretion was the better part of valour, switched from the above to a much more open aluminum mesh, the kind used for residential window screens, maybe 1/16" square openings.

 

Can anyone point me to a complete guide on how to get to my battery fan to clean the whole system including tools please. I have a gen3 2010 Prius. Thanks.

This should help, if you haven't seen it before. I watched the whole thing, even though I don't own a 3rd Gen. It's a very similar procedure to the one for the 2nd Gen, which I have performed. The only thing I noticed in this video that might be missing is plugging in the connectors that he unplugged around the 7:30 mark. I'm not sure why he didn't show plugging them back in. Enjoy.

 

One comment (only) on the above video:

You don't need to remove the rear seat. There's one bolt (12mm socket size) that holds the base of the seatback portion with the duct inlet grill. You can remove it by just pushing apart the seat cushion and back, reach in with a ratchet and extension.

 

Toyota makes a vent inlet cover that has a screen in it. About $14.
For Generation 3 models.
I also used house A/C vent filters and cut it to size and placed in between the vent and cover.
It's pretty open and will stop any fur from dogs. It catches it from my dogs.
It was only about $5 and you can make probably a dozen or more from it. You can just
rinse it out and put it back on.

 

The foam is not from Toyota?

 

No, the foam was from Lowe's I believe it was.
Frost King # F1524
You can see through it in the 2nd photo. I just took the photo against my screen.

When it gets dirty, rinse it out in the sink, or where you want,
shake it out and get it dry, them put it back in.
I've been using it for over a year and haven't had any overheating problems.

 

Do you have a part number?

 

I believe this is the part number: G92DH-47010
I can't find my paper work for it. But also found this thread:
gen 3 hybrid battery cooling fan dust buildup | PriusChat

If you scroll down to Sept 14, 2012, it shows the photo. I think this is where I found it.
Sept 18th shows the filter and part number.

Also, here is a search I did for that part number:
G92DH-47010 - Google Search

 

Thank you very much. Just searching for HV battery fan filter got me nowhere.

If anyone's interested, the two lowest prices I found (including shipping) were:
1) Toyota of El Cajon, $13.88 on Ebay
2) Modern Toyota of Boone, $12.95 on the Direct Wholesale website
