Q: how to access battery cooling fan

Do you have a shedding dog in the car (or spouse)? Other thing to be careful with is loading the rear footwell with anything which will cover the vent(s).

THIS IS A NiMH Battery - I think Lithium might be slightly different - but similar?

It does screw out, but don't press on it or it just keeps going back - it's not a positive thread - it screws into a "THING" - which probably has a name.

Then the cover pops off - with a bit of help - I used a wide thin blade under, mainly toward the bottom near the screw and there are some clips on the cover which came off quite easily.

Replacement - pop the "THING" back in - and just push the screw in - doesn't need screwing.

 

For Mama them’s fightin’ words. She does not shed.

if Mama ain’t happy ain’t NOBODY happy.

 

I reckon I shed more than my POODLE.

 

It's not a nut or a screw. It's just like the fasteners holding down the plastic cover over your radiator and the covers under the car. Turn it counter clockwise about a quarter turn applying as little pressure as you can. The part that looks like a Phillips head screw will come out just enough for you to hook it with a finger nail or small flat screwdriver. Then it just pops out like the other ones all over the car. They make special tools for these, but the best thing I've found was an idea shared here by @Mendel Leisk. It's just a paint can lid opener. That with the screwdriver should make it relatively easy.

 

My G2 does not have a filter on the one battery fan inlet so I got some double sided tape cut it in half length wise and ringed the inlet then got some thin filter material from LOWES and covered the inlet. Works good easy to see if it gets dusty and easy to replace.
If the filter is a pain to replace this is much easier and cheaper and with the oem filter removed it may increase fan velocity which is good as this method will probably flow better.
If you have a doggy back there like me that oem filter may get clogged.

 

After 3 years I decided to clean mine the other day. Looked newish still. I don't have any pets and keep my car clean. Still replaced it though since I had it open.

 

Didn't I already answer this?

 

And if Papa ain't happy, ain't nobody gives a rip.

Same here. Never have had to clean a battery filter or fan.

 

You can see from the photos, mine is as clean as day 1. I've had the cover off once before about 2 yrs ago - and again yesterday to photograph.

4½ yrs old next month. In "Car Years", that's about ... retirement age.

 

It has got a positive thread - normal RH thread - screw it out with little pressure and it pops out enough to grab or lever it out:

 

Thanks for the clarification. I was going from memory from when I took that off my wife's car to check things out. I thought for sure it was unthreaded.

 

How can we know when it's time to change the filters?

Where can one buy them?

For that pesky screw, a JIS (Japan Industrial Screw) screw driver might help. It’s cross-style as well, but locks more positively, may allow you to back it out with minimal down pressure. It comes in size no’s. 1 through 3, and I’d hazard no. 2 is what you'd need.

 

I think you just clean it?

 

See the attached instructions from the repair manual on how to inspect, clean, and replace the Battery Intake Filter.

It's part # G92DH-47070, available from my local dealer for $8.81.

 

I'd be checking it first before buying one - mine is as clean as Day 1. Unless you've got a shedding dog or other environmental dirt.

 

That's excellent. Also, contrary to what is on the manual (states that only taxi/Uber, small trips, etc), it says that it does need to be cleaned, especially when with passengers in the back.

The PDF is very good and detailed, thank you so much.



One question, though...
Behind this grayish filter, mine has another one, thicker, white, that seems even to be warm fused to the plastic... Is that not normal?
