I changed mine myself after installing the supercharger DIY.

This is a pic of a US Corolla motor, and the engine is (1ZZ-FE)

As Prozak has stated, you will need to pull the tensioner in the direction above to slip it loose.

i believe the 2zzge engines are similar location but i cant find the damn thing! what happens when u put the new one on, i know its an auto tensioner but do you have to turn the tensioner anti clockwise to tighten it back again? or u have u keep a constant pressure on the bolt with the wrench while slipping off the belt?

also how hard is it to turn the bolt? i dont want to pull and yank until i find that i've broken something because i've pulled on the wrong bolt. -_- pictures and arrows would be nice ;)

i wanna get a bosch belt when this ones through... which is another 80,000kms at least :P

you have to keep a constant pressure on the bolt with the wrench while slipping off the belt.

You don't turn the bolt (ie. loosen) it is welded to the tensioner. it is used to 'lever' the pulley tensioner (will require a fair bit of force)

also, it will 'snap' back into position when released.

In green is the bolt for the 2zz

i'd recommend using a ring spanner for the job, or a socket and ratchet.

when using an open ended spanner you will probably end up rounding off the edges of the nut.

fanks dooode. champion! now i can do it myself without having the mechanic to charge an arm and a leg to do it :D

last time i had it done my mechanic only charged me $70,, and it took him 1/2hr.. i figured it cant be that hard, so i'll have a crack at it this time.. ;)

i'v just completed the belt change,, piece of cake..

done in about 15min.. a little bit tricky getting around the last pulley, extra set of hands come in handy here..

good luck for the future guys, its not too hard ;)

thanks again for the tips,

cheers wil

90916-02468 without air conditioner

90916-02551 with air conditioner

On a side note, I recommend using a "single hex" 19mm socket on a breaker bar to get the tensioner loose. We did this on a friends celica and we ended up rounding the nut on the bolt with the double hex and then snapping the damn thing off when we used the breaker bar with single hex socket.

We had to use heaps of force to get it off. When I did mine I have to remove the under guard loosen the side guard of the right wheel to see what was going on. Definitely needed an extra pair of hands and eyes for this. Very scared to also break my bolt but my tensioner seemed to be in good nick still...

I have been given this part number: 90916-02544 (old) which has seen been updated to 99366-H1830 (new).

Anyone know which is right? same part just different number? Length wise? I am assuming H1830 means 1830cm.

I have a SA made zze122 though. same as the JPN one?

90916-02544 is what shows up on the database...

yeah just quote the that part number and see if its updated or not. but the last 4 numbers doesn't mean the length. but its pretty damn close to it... the sportivos from SA too and they have a number similar... i forgot though its on my ride thread lol.

99366-H1830 supersedes 90916-02544.

and i suppose 1830 = 1830mm not cm :P

was also told that the 99366-H1810 replaces the 90916-02551.

the length would be the key i guess. how much length difference is ok?

bosch catalog says 6pk1815 (1815mm)

sometimes the bosch catalog is wrong. i looked at the zze123 and it had the same length as the celica one... turned out it was wrong so dont trust it much... the length is always correct on ur belt if u can still see the print take note of it for future reference. toyota belts are pretty good in price anyways.

I can't see the length on the old belt. the writing is quite faded. hence the concern for a change soon.

best i could made out on my belt is 90916-02544, which seems to be right. (its superseded by 99366-H1830 now).

The toyota part is quoted at $96.92. quite expensive?

the parts salesperson told me that the 99366-H1830 is 1830mm.

I am thinking of getting a gatorback of 1815mm instead. suitable?

Hi guys, gonna resurrect this thread again. 

Looking to buy a belt for a 2004 Jap 1ZZFE.

Can anyone confirm what the belt length would be. So far seem to be confused with the 6pk1810 and 6pk1815.

Thanks
