How do i change the ac belt on mazada 1998 626 4 cylender

timing belt changes across the board are 60.000miles or 100.00klms. If there are oil leaks inside the plastic cover or the area of operation is dusty reduce that distance by 15%

turn over or run
turning over is cranking but not starting/running
not turning over indicates seized motor , bad battery starter motor problems , bad ground
turning over is cranking but not starting ---broken timing belt/chain, crank/cam position sensors , no fuel , no spark , no injector operation
best run the fault codes as the fauty will be recorded there

60,000 miles is generally when replacement of timing belts is recommended.

If this is a four cylender motor number one cylender is located closest to your drive belt/alternator belt. its gonna be on the end of the motor

heres a diagram to help you, loosen the bottom bolt a few turns then loosen the top bolt then loosen adjusting bolt to loosen belt, use the adjuster to tighten the new belt then tighten top and bottom bolts, hope this helps,

Remove timing belt cover, hope this helps on how to align the cam and crank gear's.

you'd be better off putting a Hub asy on the Compressor.Just because the compressor is locked up doesn't mean the Hub Bearing will not turn freely on the Clutch asy, just leave the wires to compressor disconnected from the Hub/clutch asy, the belt will ride fine , on a bad compressor, as long as it isn't engaged

change the control modul. that control voltage to the coils. it sound like it not bleeding off fast enough the control modul is under the coils. befoe changing any part remove ground off battery. befor change any coils u could of swop to see if this is still not firing

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
