serpintine belt help

[06speed]

can anyone help me out with and easy how-to on loosening the belt up.

[Tokay444]

Put 15mm box end wrench on bolt through tensioner pulley. Push pulley up and towards rear of the car (in the direction indicated by the arrow). Slip belt off of crank pulley.

Ah. I knew there was a difference between oem and my napa tensioner.

[Raider]

It is in the friggin How-to database sticky even.
DIY replace belt tensioner

Search fail.

sorry, i meant to say is there an easier way to get to it rather then taking the tire off.

[Raider]

Put it on ramps. That is how we did it on my wife's CX-7.

If taking a WHEEL off increases your difficulty level to a degree where you're looking for an easier way, don't bother with the tensioner.

^^^This.

I generally loosen mine from underneath. Makes life 1324089176142309x easier when putting the belt back on.

Remove the undertray and get at it from there. Once you secure the box wrench, push towards the back of the car and slip the belt off the AC compressor (front of the engine, right at the bottom).

A ratcheting box wrench works really well here.

Wrenches tend to bust knuckles and pinch fingers. I have found this to be quite effective.

btw, make sure and get yourself an oem belt...you'll save yourself unnecessary stress, cuss words, and time.

i recently had my ac compressor pulley go bad, ruined a brand new oem belt. bought a dayco since autozone was closer, and it took me having to re-think wtf was wrong. i read on another thread aftermarket belts tend to be shorter, although not by much, but that little does help alot when u can't get it over. no matter how much i compressed the tensioner, i couldnt get the belt just far enough to slide over the water pump pulley.

after not being able to find an oem belt locally, i went back and fully compressed the tensioner and actually got the dayco on by removing the power steering pump getting the belt over the top of the ps pulley, then pulling up on the pump, got the bolts back in and finally the dayco belt was on...funniest part of all, since its slightly shorter, the tensioner literally did not decompress.

I bought my belt at autozone took it to dealer 20$ and they put it on. total 50 bucks well spent.

I did this the other day. It was tough for me to get enough leverage to loosen the tensioner enough. I looped a ratchet strap through a box end wrench and hooked the other end towards the back of the car. Cranked her down, slid old belt off, new one on. Done

my ac pulley is going bad, dropping it off at the dealer tomorrow. was going to get the belt done within this month, glad my pulley is going bad now and not after i have the belt replaced. actually searched to see if anyone else's had gone bad. i'm at 94,xxx miles, ac pulley started to make noise at idle, got progressively worse, when i looked at it, looked like the 3 circular pieces (clutch part?) were "catching" when the a/c wasn't even on and spinning, bearing/clutch part that engages going bad i guess. will know more tomorrow, hopefully just a pulley replacement and not an entire compressor replacement.

could have done the belt myself after reading the how to, but just lazy.

@isypsi what was your conlusion to your problem? I seem to have the exact same problem. ac pulley rattle with a grinding noise with ac off, with ac on when clutch on cycle resumes, pressure plate moves with pulley, with ac on and clutch cycle off however it behaves as if ac off conditions i mentioned.

[aviator79]

I undo it by tilting the PS pump. Much easier IMO. Still a PITA to route belt as I took mine off CX-7 and had to look at my MS6 to figure out routing.

[megimpy]

To anyone who had a similar problem to mine. It was the AC bearing. It was grease-less. One AC repair shop even quoted me 1400 for the repaor when all it needed was a 30 dollar bearing.

[digitalskillz]

Got a question for you guys. I had a speed3 but sold it before I got a chance to put in the replacement AC compressor and clutch assembly I had bought.
A year went by and I decided to sell the part on ebay to a mazdaspeed6 owner.
Their mechanic said the part was different and wouldn't fit.

There seems to be 2 different styles of AC compressors. Can you tell me which one you guys have on your speed6's? I've actually seen references to both.

129mm clutch:


105mm clutch:


Thanks.
