-
This guide is how to remove the alternator from a V6 engine
K8, KLDE + KLZEThere are 2 bolts and a locating pin that hold the alternator in place on a mazda V6, along with the main power cable and a small connector block.
You will need to disconnect the battery before startingThe green arrow
Points at the belt tensioner, this keeps the belt from slipping when running the engine, it is a free running wheel that is adjustable for tightening the beltThe RED Arrow
This points at a 10mm bolt that you can see on the side of the engine from above, this is the alternator belt tensioner, you need to undo this until the belt becomes loose enough to remove (if necessary or changing)The yellow Arrows
These point at the 2 bolts that hold the alternator onto the engine block, you can easily see the top one which has a painted black bracket attaching the top of the alternator to the engineThe other bolt is located under the front of the alternator at the bottom arrow
The red arrow
Is the locating pin mount, it has a rubber grommit inside to take any vibrationThe blue arrows
These point to the 2 bolt mounts that hold the alternator onto the engine blockThe pink arrow
This points to the cable connector that takes the main feed to the batteryThe green arrow
points at the cable block that just clips togetherTo remove, slip the belt off the end of the alternator, loosen the bottom bolt first but do not yet remove it, then move to the top bolt and remove it, the bottom bolt will now hold the alternator as you tilt it forward and you can now access the cable block to remove and the nut to undo the main power cable, once these are off, then remove the bottom bolt and the alternator will now be free to remove
Just copy the removal in reverse to refit
When tensioning the belt again do not do up as far as possible, just keep checking the belt when retensioning to the point when there is hardly any play in the belt but not absolutely bar tight as it can damage the alternator, if its not tight enough it will squeal on start up :D
