how to fix belt slipping
 

when i get about 4k+ i can hear this high pitch sound coming from the main drive belts. And i also notice the temp rise to halfway right after i get off it SOMETIMES. I have a dual alt. belt pulley and one seems to be a lil looser than the other which might be the problem, but what are the negative effects of this..waterpump etc, any ideas on how to fix it? btw i dont have an airpump. any advice is appreciated thks!

Either try getting two new belts that are the same size, try prying with a 5 foot pole then tightening the alt. bolt, or get this: http://pineappleracing.com/Merchant2...tegory_Code=EA

I have had no problem running with only one alt. belt that was tensioned with a pole then secured.

Thats a good way to burn out accesory bearings...rule of thumb is that the belt should have approx 1/8" of deflection, a 5 foot pry bar would make it too tight.

Just get two belts from Mazda, I have found that most aftermarket belts don't have the correct bevel on them to properly seat in the pulleys. Goodyear gatorbacks are good, but even they I've found can vary by length ever so slightly.

The OEM belts are about the same price as the aftermarket replacements, give the factory ones a try.

True, I forgot to mention that. I by no means was pushing as hards as I could on it , just enough to get it as tight as it needed. The pole was just very convenient to grab.

thks for the info im sure its just the different sized belts..also i hear this sound like "change(coins) falling on the ground" coming from the belts, maybe a bearing? it might be coming from my a/c belt tho which im not to worried about..any ideas on that?

Could be.

Pull all the belts off and manually (by hand) turn all the pulley's and tensioners by hand and check for play, tight spots, loose spots, anything that feels abnormal.

I've seen, for example, the P/S belt tensioner pulley cranked tight on the adjustment bolt, but the pulley itself was left loose on the bearing (the big 17mm nut on its face) and that can cause a noise like what you're describing.
