Engine oil and Trans fluid change 2021 Mazda CX-3

I perform an engine oil and filter change, as well as a transmission drain and refill on my 2021 Mazda CX-3

Wow!! Those Quick Jacks are very handy! This video was a big help, Thank you for sharing 😁

I should have bought my quickies years ago... I am glad this helped. Thanks for watching.

Thanks for the video and the time you spend on it!. It would be good to see a video where you change transfer and rear diff fluids on this car.

[@thereddoorgarage8606]

This car is not an AWD, but my daughter's is, and I will perform these items when she gets some time...thanks for watching.

Very good info. Good editing. Keep up your work ^_^ I've been using the Cx-3, and I will definitely follow your instruction.

[@thereddoorgarage8606]

Thanks for the comments. I started this channel as a form of therapy to help me through some issues. I'm glad you found it helpful...

Very helpful video! I own a 2021 mazda cx3 CVT. I wanted to be sure I had a good understanding of where the filler and drain bolts were located. Thank you!!

Glad it helped. Thanks for watching.

I don't believe the Mazda has a CVT, automatic transmission

[@xxMORZYxx]

Yes they come in a CVT and 6 speed manua ​@megaman4201

Thanks for watching.

thanks for the video It would be good to show the old fluid even running a finger through it so we can get an idea roughly what the fluid looks like at various mileage intervals

[@thereddoorgarage8606]

Good point. I didn't think of that at the time. I was surprised at how dark the fluid was for how little the mileage was. Thanks for the tip, I will use that suggestion on my next fluid change video coming soon. Thanks for watching.

Well done, and you even filled your oil filter before installing it. Watching because I might buy a new Mazda, they all seem similar to maintain. Thanks!

[@thereddoorgarage8606]

My last vehicle was a Golf mark 5. Not easy to work on, expensive fluids and parts, and special tools needed. Both of my Mazdas are easy to work on, use regular tools, and parts aren't an arm and a lung. It also helps that they drive great ( MX-5 is a blast) Thanks for watching.

Hello I'm also going to start an oil change of my CX3. I didn't notice if there is a gasket to change on the drain plug. Can you enlighten me on this point? Congratulations for your videos, they are very informative.

[@thereddoorgarage8606]

Thanks for the nice comments. I always change the drain plug seal...pick them up when I get the filters from the dealership. I've been told that it is not necessary every time as long as the seal is in good shape. For a few bucks every year I have peace of mind. Thank you for watching.

Great video, what size of extension wrench do you recommend for this job?

[@thereddoorgarage8606]

I just used my 3/8 drive with two 10" long extensions. Worked well because the airbox was removed.

He didn't change the transmission filter. Is the same thing when you change the motor oil. The transmission pan have magnets that receive debris from the transmission.It's supposed to clean the transmission pan, the magnets and change the transmission filter. Is a big blooper.

[@thereddoorgarage8606]

Not necessarily... changing the fluid at this low mileage will help reduce internal dirt buildup, as well as replenishing the cleaning properties of the lubricant. As I have mentioned in the video I will be changing the filter on my next transmission service, still well before the recommended fluid change interval. It is possible to safely change engine oil without the filter after only a small amount of mileage , again before the recommended interval.

[@123Osaka456]

So you used 4 L of fluid or 8 L of new trans fluid?

[@thereddoorgarage8606]

I only added 4 litres of new fluid because that is all that came out. In the future when I drop the pan and change the filter I will catch and measure the fluid in the same manner, and replace what comes out. Impossible to get all of it out of the torque converter, but the cleaner the fluid the better to help prolong the life . That is the hope anyway. Thanks for watching.

[@amarkundan9801]

How often should the transmission fluid be changed? Right now our cx3 has 33k miles and i was thinking of changing it. Also, should transfer case and rear differential fluid be changed at the same frequency as transmission? We do not tow with the cx3 at all. Just a daily driver.

[@thereddoorgarage8606]

The dealership will tell you that mazda has a lifetime fluid in both the transmission and transfer/differential cases. Lifetime for them is just until the drivetrain warranty expires. It is never a bad decision to change these fluids early, or often. Some would say it is a waste of money, but I would say that maintaining your vehicle will let it last longer, as well as give you an opportunity to check for, and address any issues you see. As far as the transmission fluid is concerned, draining and refilling will never get all of the fluid out. A transmission flush and refill is needed for that (as well as a trip to the mechanic who has the machine to perform this service). By dumping and filling you can extend the life of the fluid by continuously diluting old fluid with new, and no trip to the shop is needed. I will be changing the filter on my next service but did not on my first service. Sorry about the long reply, but thanks for watching.
