MX5 AUXILIARY BELT REPLACEMENT : MX5 HOW TO

#miata #mx5
Changing the auxiliary belts on your mx5 should be routine maintenance and should be replaced once a year.
Its a nice simple job to do and here is a step by step video on how to do it yourself.
If you neglect your belts it could lead to them snapping, causing you to loose power steering or even worse loosing your water pump and causing your engine to overheat.

This was one of the most helpful belt replacement videos I’ve seen for this car. Showed exactly which bolts to loosen first, and which bolts to tighten up after the belt was put on. Definitely will be using this video and your timing belt video when I do mine. Nice job!

[@Project380]

that was exactly my aim in making the video, im glad it helped 😎

[@drummadryanoj]

This is such a perfect tutorial. Thank you so much. You weren’t lying about the bottom pivot bolt on the alternator though. Saved myself £80 on the auxiliary belt, the power steering belt arrives later this week and I’ll be referring back to this video for sure. +1 subscriber

The bolt behind the alternator is just a pain in the ass... that's crazy!!! Thank you very much for the video - it was very helpful

[@Project380]

Yeah that bolt is very annoying. Your welcome 😊

[@brileywalter7559]

I’m currently doing this!!😅is there any chance you can just get away with not undoing it?

[@Project380]

@@brileywalter7559 i wouldn't advise it but you can lever the alternator carefully

Super helpful video! I was really scared of this job as it was the most complicated thing I was going to do on a car yet, but it turned out a lot easier than I thought and it only took me 1.5 hours. Worst was the bolt behind the alternator, really hard to loosen, but I was able to move the alternator using some force with a screwdriver anyway.

[@Project380]

ahh well done, yeah tht is the worst bolt to do

[@arrivendrive6831]

The video was spot on. I just did my belt and used this as a guide line. Brap on

[@Project380]

im glad this video helped you 😎

[@SnazzyLobster45]

Thank you so much for the video! Just ordered both belts for mine and this video makes it so easy to follow

[@Project380]

i hope the video was helpful for you 😊

Thank you for this video! Following this I was able to effortlessly change both belts knowing beforehand exactly what to expect, what to do and exactly in which order. Luckily my back bolt was not so tight, so I was able to get it out without even having to lift the car! Great work

[@Project380]

thank you that means alot. im glad this video helped you out

[@lymnaea11]

Thanks for the help I’m starting to have a go at few jobs on my svt sport not as hard as I thought and gives me more satisfaction and confidence to tackle next job (slave and master change)

[@Project380]

im glad my videos have helped, if you need any further help just shoot us a message on insta, ill be doing a video on master and slave next year on the mk1

so true 😊

Right on time. I've been popping belts constantly for 3 years. Just replaced everything that turns and pulleys even waterpump and everything crank because of all of my mistakes made compound problems. Main thing is maybe not tightening the alternator belt tight enough.

[@ChutneyInc.]

Mine turns about a half turn, I'm going to tighten mine tighter than you did tho and work my way from there

[@Project380]

dont over tighten or it could cause bearing issues, glad i helped

[@ChutneyInc.]

@@Project380 man it seems like there is a very thin line for error

[@ChutneyInc.]

Which bearings? Because I just replaced water pump alternator and all pullies. Well I'm doing the power steering when I return from Japan

[@Ogma3bandcamp]

Very clear. Thanks!

[@Project380]

Thank you I hope it helps

[@MihaiZavoian]

for the alternator bolt I used 2 spanners for leverage under the raised car, just need to remove the undertray.

[@Project380]

well that's definitely one way to do it 😂

[@fifcyk]

That helped a lot! Thank you! Great video tutorial :)

[@Project380]

thank you 😎

[@Motiahmed330]

For those wondering, the two belt codes are : 4pk885 (2:40) and 4pk850 (3:29) 4pk850 is the belt WITHOUT a/c. if you have a A/C and power steering, you need 4pk945

[@Project380]

thank you 😊

[@yarnotilman442]

is this the same for the 1.8 as the 1.6?

[@joeyramirez6252]

Is it possible to list all the tools you used for this? I want to get everything from shop that I need all at the same time since I have to skate there because the cars broken and I don’t want to have to skate multiple times. Thanks !

[@Project380]

14mm socket or spanner x 2 12mm socket or spanner x2 pliers 10mm socket you dont need much, honestly just a spanner set

[@2124spike]

Thnx buddy it was helpfull i did my belts and it tured up ok. Big thnx

[@Project380]

Glad it helped

[@michaelbaskin7905]

Imagine not saying the sizes... could have been a perfect tut

[@Project380]

😂

[@meinungsfreiheit2023]

A friend of mine changed them for me. Now they make some terrible sound when I start the engine. After a few seconds it is oka again. Probably I have to adjust the belts again. Do I just have to adjust the one screw for each belt to make them kind of stiff, or do I have to loose more screws before? Thanks a lot for your help.

[@Project380]

yeah you need to slacken slightly the other bolts so you can move the alternator and PAS pump, if not you will bend the adjustment bolt. yes sounds like they need adjusting

[@JakeBarber-g8h]

If you struggle with the alternator pivot bolt, I managed to shift the alternator with an old mop handle

[@Project380]

Just watched the video, wish me luck, as I am now about to attempt some of this 😂

Excellent video, worked perfectly following this step by step. If you can do one on how to replace a thermostat when you have a reroute kit on, that would be epic 😂❤❤❤❤

@@Project380 I got it sorted, just so little space to get the spanner on the thermostat housing.

[@LampitoBrothers]

Hey man, just a quick question i have a 4PK855 for the power steering belt (I dont have a/c) rather than the 4PK850 you mentioned in the video. Couls the different hurt at all or am i okay to run the car as it is? Otherwise fantastic video, made the whole process smooth as butter!

[@Project380]

Hi there. Yes it should definitely be an 855 if it's a 1.8. I'm unsure what a 1.6 belt should be.

[@michaswierkowski4189]

Great Video👍🏻 Any suggestions on issue like this..... Changed the P/S belt with 4PK855 After change on idle it squeals constant, it stops under load, About 3k RPM Bad belt or unproper tension? If so is it too tight or too loose? I'm running out of ideas😢 Thanks for help🙏

[@Project380]

Sounds like it's too loose. A tight belt usually humms underload

[@michaswierkowski4189]

@@Project380 Hey, Thanks for feedback. Unfortunately it found out like it was the fault of timing belt tension pulley. Before that the water pump was the suspect😅. The sound I mentioned earlier didn't go away even after removing alternator & P/S belt🙈

[@louisrobinson5952]

trying to get the very first bolt off for the power steering pump and its making a horrible crunching squeeking noise when i try to loosen it, dont want to risk snapping it as i have ptsd from doing that before, what can i do to loosen it without risking it snapping off, its pretty rusted

[@Project380]

OOOOO thats scary, use some penetrating oil and work it back and forth to work it in, hopefully then it will start to loosen. good luck

[@louisrobinson5952]

@@Project380 replaced tbem, still squeeking, i did it to around a quarter turn tight, any reason why its still squeeking?

[@f1gridlock]

Is it possible to change the alternator belt without removing the pulley? Because the bolts on my pulley are seized with rust

[@Project380]

the water pump pulley? if so yes. the pulley was coming off to do the timing belt

[@tomsmith2540]

Great video. I presume it'll be the same for a mk1 mx5? cheers.

[@Project380]

thank you , yeah the only difference is on an early 1.6 where they use a v belt for the alternator

[@NP_NB8C]

Bang on video man 👌🏻

What size is the crank bolt ?
