As you may of recalled from one of my previous post regarding the alternator relocation.
You can check it out here > https://tracktuned.uk/abs-alternator-relocation/ 😎
I used a Mazda 3 alternator to move the alternator to under the inlet to free up room on the exhaust side for big turbo things! 😜
Mazda 3 alternator part number: A3TJ1091 110A
Mazda 6 alternator part number: A3TG1391A 90A
This required a new belt route, I retained the OEM tensioner which you can see below and it worked well.
But on the built 2.5 engine I’m doing I wanted to tidy this up & make the routing far simpler.
I hunted for a eccentric tensioner with a similar size to the OEM units to go in place of the lower idler pulley that is used on NON-AC cars.
I found a GATES T38231 to be the perfect fit. You can get much cheaper tensioners but I’ve always had really good luck with Gates products, you need to fit a small washer behind the tensioner otherwise it will catch on the timing cover where there is ribbed section. 💡
I’m planing to get a bulk of these tensioners in and modified so you don’t need to run the washer and provide as a kit including the alternator bolts & belt, let me know if this is something you guys would be interested in?
The belt I used was a GATES 6PK1470 It’s a good fit and you need to slide it onto the water pump last, otherwise you will struggle.
The end result is a very tidy setup.
You can see it’s a big improve over the old setup I had and makes thing a lot simpler & cleaner install.
It be great to hear your thoughts on this! 😃
Law, what bolts do I need to grab so I can put the alt on?
So I re use the a/c bolts? Looks like they need to be a little longer than the OEM a/c mounting bolts.
I’m Getting super close!!!
I used some M8 cap bolts. I will get the measurements for you and update the post.:)
Awsome job. Will do the same with my FMSC setup.
Thanks. 😀 Hope your install goes well.
The only think I worry about is the water pump is now spinning backwards compared to the factory OEM direction, is it not?
It spins the same way as OEM, anti clock wise. 🙂
Oooh, I saw that backwards in my mind. You are correct. A side note, I was trying to find this tensioner over here in the USA and it doesn’t seem to be a good part number. It just comes up as only available in the UK and other Eu countries. Any tips of something else to use?
