Me again, your other video about the transmission fluid change helped me so much a few years ago and every time I do it... that it is time to finally tackle the front and rear diffs. Thanks for the video... let's keep our CX-5x rolling!

Just an update, the fill plug for the rear differential is impossible to remove if you use a socket... now I am going to look for a 24mm wrench; there isn't enough space for the socket. 😞

Please note. In 2016, Mazda changed the recommendation for the transfer case and rear differential on the CX-5 from an 80w90 GL-5 to Mazda Long Life Hypoid Gear Oil SG1. And the drain plug is 24mm but 15/16" (23.8mm) certainly works. The upper refill plug is 23mm. This is a Japanese car! Finally I drained out 10 oz of fluid but it certainly wasn't at the very top of the fill plug. Top of plug took 14 oz upon refill. Mazda and other OEMs tend to underfill so always smart to check early in a cars life. The actual capacity of this diff is 0.45L or 15oz. Rear diff is 0.35L or 11oz. I removed 10oz so my rear was filled properly from the factory. Same bolt sizes. For the tranny, Mazda also upgraded the oils to a FZ type fluid. This is a longer life fluid. If you have a 2013-2016 then you have the RED ATF tranny fluid while the FZ is blue and much better quality. Mazda did this due to high failure rates of this transmission and also made some engineering improvements. I advise removing the original fluid in the 2016 and pre cars. Replace with FZ but you need to cycle the fluid. So add FZ, run the car (shift it several times), and then pull the fluid. Then fill again with FZ. The Skyactiv-G transmission takes a total of 7.8L. However, unless you flush (Do NOT Flush), you will only be able to remove about 4 liters. So you'll have a 50/50 ratio. But if you add and then immediately change, you'll have 75% FZ fluid. These are COMPATIBLE fluids. Next 30K miles, I recommend to change again. At this point, you're basically running 85-90% FZ fluid. I also am a fan of Lubegard Platinum additive. I hate most additives but this is a great additive for transmissions (less heat, more friction modifiers and longer life).

Are you positive that the manufacturer under fills their differentials? Is it possible that having your vehicle up on ramps (not level) might have an effect on these measurements? As you pointed out toward the conclusion of your video, Japanese vehicles use metric sized bolts, so it's a good idea to buy yourself some metric sockets. Thanks for posting the video.

@@pete5534 If you are asking me, I did not make this video. Just trying to help and provide more factual information for people. That can be a problem with home garage mechanics on KZread. Do not get me wrong, this is absolutely a helpful video & his others. I just bought my wife a CX5 so it gives me a great overall perspective of the job(s). Just not completely informative, and yes, he looks like a bit of a Homer for using a SAE socket. Having said that, that 15/16" is actually a tighter fit on that drain plug bolt! It is not uncommon for cars and trucks to arrive from the factory with underfilled fluids. Note, I did not say this was necessarily damaging. Personally, I prefer to be at max fluid level as more volume means it stays a bit cleaner cleaner over the life of the lubricant. At least in theory. Does that absolutely translate into longer life....nope, not at all. If you are still within the lower bound of the fill spec, you would hope the manufacturer would have lots of test data showing no significant compromise in the life of the component. Sorry....the R&D engineer has come out...

thanks for these tutorials good info in this and the transmission change too, needed these because the dealer charges too much.

thank you for this video! props for holding a camera while you made the change

Thank you for your video! Please take your safety seriously. These ramps can go down while someone is under the car. I usually put some wood under the car that can hold weight of my car, as addition.

Just did mine, seemes it was low on fluid from the factory, I had it on ramps, like you, when i took fill bolt off, no leakage, was definitely underfilled. I filled until it weeped out, which was 1/2 a quart.

Very informative! Thanks!

I prefer to use all OEM fluids, especially if still under warranty, vehicle should be level when you are refilling.

Thanks for doing a video on this. Is the front diff the same as the transfer case? That’s how it sounds in the manual. Or is there also a transfer case fluid that needs to be changed? Thanks!

Trans, transfer case and both diffs should be filled when vehicle is level. You should have the back put up on jack stands if you have ramps under the front wheels.

That’s not how an overflow fill holes work. They are designed to overflow when the are filled to the correct quantity of fluid when the car is level. It is physically impossible to do this with the car 8 inches off the ground in the front. It’s like trying to fill a glass to the top while it’s tilted.

I just changed the transmission fluid on my 2015 mazda 3 with 55,000 miles, and 4 years old. I made sure to read mazda official documents and owners forum and asked the service advisor that the fluid to use is the Type FZ that mazda sells. When i drained it, a brownish red fluid came out. I was surprised because the fz atf is blue. I wonder if they put a different fluid at the factory for the break in period.

*Make more videos about this, invest in quality and you will have succes.* *I own a Mazda cx-5 2018, I never change the fluid from the differential and I have 209.000 KM, I think my differential is rip, right?*

This so much easier than Subaru. That’s why I sold my forester😅

On some furoms they mention of using shallow sockets when tightening or loosening the drain and fill plugs. Dont know why so. I dont see it being used here but regular sockets. Do we really need shallow sockets for them or regular sockets will do?

How much the fluid i need for mazda cx5 2012 differential fluid? Thanks

Hi, nice video - maybe you or someone have insight into my issue. On a 2020 CX5 AWD I pulled out the driver side axle and some type of fluid leaked out (around 1/2qt) . After hours of google & youtube im hearing differential gear oil (hypoid SG1). However... when i took out the fill plug (mine has one same place as this video) and tried to fill it up- it did not accept any more!!! Any idea where i would add the missing oil? While the passenger side axle goes straight into the differential, The driver side axle seems to go into another gear/differential housing... but unsure. Any help would be nice.

Im not familiar with the newer models, but i would take it for a short drive, and pull that fill plug again and see if you can add the extra 1/2 qt. Also make sure you are doing this with the car as level as possible. If you do this with just the two front wheels on ramps or jacked up you won't get an acutate level reading. Good luck

On average the differential hold about 1.0 litre of fluid. You fill both the front and rear until you see fluid dripping out from the fill plug.

If i can touch fluid up to my first pincky knuckle its filled and you wont have to worry about excess fluid dripping out all over your floor.

If you live near salt water and/or hit deep puddles, etc. always recommended to change a bit early. Fluid is cheap, units are expensive.
