Changing Mazda Navajo alternator

Hi Julie,here's a link to your belts. 1994 Mazda Navajo Serpentine Belt Routing and Timing Belt Diagrams

If the alternator is on the top in the open, just loosen the alternator bolts a little bit. Then push the alternator to loosen the belt to remove it. Do the opposite to put the new belt on.

If the alternator is buried under a lot of other things, it's a lot tougher job.
Hope this helps.

IF IT IS ON THE OUTSIDE OF THE OTHER BELTS, ALL YOU HAVE TO DO IS UNBOLT THE TOP OF THE ALTERNATOR, AND PUSH IT IN TO LOOSEN THE BELT FOR REMOVAL! IF IT IS IN BACK OF THE BELTS (ESPECIALLY A SERPENTINE BELT) YOU'LL HAVE TO REMOVE THE SERPENTINE BELT FIRST! THERE WILL BE A TENSION PULLEY HOLDING THE BELT TIGHT! YOU'LL NEED TO USE A WRENCH TO PULL THE TENSION PULLEY TOWARD YOU TO LOOSEN BELT! WATCH HOW YOU REMOVE IT, BCUS YOU'LL NEED TO PUT IT BACK ON THE SAME WAY! THEN REMOVE, AND REPLACE THE ALTERNATOR BELT AS BEFORE, THEN REPLACE THE SERPENTINE BELT!

LOOSEN ALTERNATOR BOTTOM PIVOT BOLT THEN LOOSEN ALTERNATOR TOP BAR BOLT.THAT WILL ALLOW ALTERNATOR TO MOVE INWARD TO SLIDE BELT BACK ON.

See if u kno some thing about mechanics u will find the adjustment bolts of the alternator on top u will have to loosen them & push the alternator witha rod inorder to loosen the belt & remove it & fix a new one & then again pull the alternator, will pulling it not too tight & not too loose then tighten the bolts u had loosen them

If your engine are the 1,6 l , it is the same engine as my MX5 91.
You have to remove power steering belt first if you have one. Loosen the mounting bolt located behind the pump pulley, then loosen the tensioner bracket bolts( one on the engine bracket and one in front of the adjusting bolt). After unscrew the adjusting bolt and push down the pump. Remove the belt.
Now, it is the alternator. Loosen the mounting bolt located under the alternator, then loosen the tensioner bracket, but only the only in front of the adjusting bolt. Unscrew the adjusting bolt and pull up the alternator and remove the belt.
When you tightening the new belt, the belt should be able to make a 1/4 turn, to make sure it is not to tight.

Loosen alternator right back You will have to loosen pivot bolt underneath alternator Replace belt and tighten alternator until you can move belt about 5-6mm by pushing on it with two fingers Quite fiddly job Not much room

You've got to loosen the mounting bolt first, which is located behind the pulley itself. Rotate the pulley until the large opening allows access to the bolt, then use a socket with a narrow head to turn the bolt, just until it starts to turn freely.
Then there are two locknuts on the adjuster; one right near the mounting bolt and one underneath towards the middle of the pump. Loosen both of those, and then *finally* you'll be able to turn the adjusting bolt that faces the front end of the car on the end of the adjuster arm. It's a long bolt; just keep turning that thing until the belt loosens enough to come off the pulley.
Best of luck!

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
