Hoe to replace serpentine belt on 1998 mazda protage

You are dealing with a misfire.It clears up at 3000.RPM A jump timing belt can do this or a broken valve . Also a failed coil pack. Lets go with a failed coil pack.Because of the strategy that is used a failed on the engine smooth at 2000RPM (neutral) No. 1 and No. 4 are fire simutaneously and No. 2 and No. 3. simutanueously. with the engine running lift the plugwire to number 4 does the engine stumble if it does this is the working cylinder and there is nothing wrong go to number 3 you may have to use number 2 engine running wire pulled out does the engine stumble if there is no change you found the problem.Basically what yopu are doing is checking for spark at all the cylinders

• There is only one drive belt and that is the serpentine belt.
• And of course the timing belt.

Click on the following free direct Link. It has several Diagrams including the correct Serpentine/Drive Belt Diagram for your 1998 Mazda Millenia based upon your Engine Size and unspecified Engine Options.
Included are Instructional and Directional Diagrams on the locations of the various Adjustment Bolts/Nuts which will have to be loosened in order to remove the Belts; and tightened in order to reinstall the Belts.

With the belt off, inspect all of the pulleys and rotate them, noticing if any wobble or are cracked/bent. Any misalignment will tear and throw a belt. You can stand at the front1 of the car and eyeball a pulley to see if one across or below it, is out of line.

Here's a link to a series of videos that will explain how to change the serpentine belt.

Here is a diagram of the belt routing which will help you put the belt back on correctly...

Check your battery cables and have someone check your alternator output voltage, it should be 14v when the car is running. Check that the belt to the alternator is not loose.

Could be a defective plug or clogged injector What cylinder was IDd. Isolate the problem cylinder swap the plug from a good cylinder see if the miss moves with the plug,if not try having the injectors cleaned. That should get the zoom zoom back.

It looks like you may have 2 serpentine belts, but when one fails it almost always gets tangled into the any other belts and they all end up coming off, all of the problems u listed are driven off your belts, replace the belts and hope that the overheat didn't cause any damage to the engine. And yes you have what are called serpintine belts and there is a tensioner for each..

Simply check is to replace the serpentine belt tensioner. Looks like this:

Another reason you might have alternator going to die. Try to rotate the alternator rotor without belt on it. If you need to use force no free rotation, replace the alternator.
Please kindly let me know if you need more info
Good Luck

just push down on the top pulley (the smaller one) as for getting the new belt back on make sure your belt came with the "tool-kit" which helps you get it back on...


ILL NEVER BUY A MAZDA AGAIN!!! man what a problem getting PARTS!
