Removing a belt tensioner on a 1994 Mazda B3000 what size of star socket do I need???

3.0 twin cam
or
3,0 Push rod head. OHV????? there are 2 engines same
displacement USA. aka. 2v or 4v engines. not the same.
presume accessory serp belt tensioner.
buy the set of torx and no need to worry.
the dealer, does not spec the size of all 2000 bolts/nuts on the car.
they just sell them by P/N#
what you can do is have it in your and.
go to any autoparts store on earth
to the tool Isle. to the torx section and match it in 5min work/
or ask the clerk for help.
OOPS not off yet sorry
buy the set then when done sell the set for 2x what you paid for them on fleabay.(par there)
at dealer and rock auto, every brand of every tensioner are all hex bolts. not one torx. (male or female)
zero
so you car has hacked parts there or not in USA,
why not post photo the parts you do not understand.
seeing is worth 1000 words, omg wrong parts on an engine, (shocking)
no country post or VIN so we can see what it had new,. and sold to where.

now I will quote the SM to you.

1. Attach a 15mm socket or wrench to the bolt attaching the tensioner pulley.
2. On all 3.0L (OHV) engines, rotate the drive belt tensioner clockwise to relieve belt tension and slide the belt off the pulleys.
3. On 3.0L (DOHC) engines, rotate the tensioner counterclockwise to relieve belt tension and slide the belt off the pulleys.Rotate the belt tensioner and . . .

remove the belt from around one of the pulleys to remove the belt
A very useful tool kit is available to use for releasing the spring loaded belt tensioner


this is the special too for FORDs
is has special star end there,
some actual tensioners have 3/8:? or 1./2" ratchet drive square socket hole there and breaker bar works there best,
of no ROOM there they made this for fords.

Question edited for clarity, we don't do well on abbreviations :>)

How to Replace Spark Plug Wires Ford Ranger Mazda B3000

2012 Mazda 3 I touring Skyactiv - Takes a 38" 6 groove serpentine belt- Very hard to find. The only place I found besides the dealer it Advance Auto but they had to order from the warehouse. There are three grooved pulleys and a smooth tensioner. To relieve the Tensioner you will need a shallow 17MM socket, it is a bit difficult to see, but if you stand on the passenger side the mount point for the socket is to the left of the tensioner shock. The Tensioner shock is just above the smooth tensioner pulley. All the threaded pulleys' (Drive, A/C, and alternator are within the serpentine belt, the tensioner pulley is outside the belt pushing down on the belt. The easiest way to replace this belt, First remove the old belt by placing the socket on the mount point and pulling up on the ratchet towards the rear of the car, then pull belt off. Next remove socket, place the belt over the drive pulley (this is the one on the bottom to the rear of the engine. ( you will see there is another belt on this pulley on the back side.), then put the belt over the A/C pump bottom front. Keep tension on the belt so it stays in place. Now put that socket back on, push up to lift the tensioner pulley and slip the belt over the alternator pulley. Make sure the belt is sitting properly on each pulley and under the tensioner pulley. Good luck. I have run into quite a few problems finding parts and information for this particular model. Good luck. Hope this was helpful

The Camshaft Position Sensor is located within the Ignition Distributor assembly, although removeable, it is not serviced separately.

3.0L And 4.0L Engines

1. Disconnect the negative battery cable.
2. With the vehicle in neutral, position it on a hoist.
3. Remove the splash shield.
4. Rotate the accessory drive belt tensioner clockwise for 2001-2004 models and counterclockwise for 2005-2006 models. Remove the belt.
5. To install, reverse the removal procedure.

Serpentine Belt
All Navajo and B Series Pick-up engines utilize one wide-ribbed V-belt to drive the engine accessories such as the water pump, alternator, air conditioner compressor, air pump, etc. Because this belt uses a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than on engines where accessories are pivoted and bolted in place for tension adjustment, such as the MPV. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. The two most important points are to pay CLOSE attention to the proper belt routing (since serpentine belts tend to be "snaked" all different ways through the pulleys) and to make sure the V-ribs are properly seated in all the pulleys.

Although belt routing diagrams have been included in this section, the first places you should check for proper belt routing are the labels in your engine compartment. These should include a belt routing diagram which may reflect changes made during a production run.

1. Disconnect the negative battery cable for safety. This will help assure that no one mistakenly cranks the engine over with your hands between the pulleys.
   

Take a good look at the installed belt and make a note of the routing. Before removing the belt, make sure the routing matches that of the belt routing diagrams. If for some reason a diagram does not match (you may not have the original engine or it may have been modified,) carefully note the changes on a piece of paper.

1. For tensioners equipped with a 1 / 2 inch square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself.

1. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioners internal parts.
2. Now finish removing the belt from the other pulleys and remove it from the engine.
   

To install:

1. While referring to the proper routing diagram (which you identified earlier), begin to route the belt over the pulleys, leaving whichever pulley you first released it from for last.
2. Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the belt.
3. Once the belt is installed, take another look at all the pulleys to double check your installation.
4. Connect the negative battery cable, then start and run the engine to check belt operation.
5. Once the engine has reached normal operating temperature, turn the ignition OFF and check that the belt tensioner arrow is within the proper adjustment range.

Hope helps (remember rated and comment this).

Below are diagrams for both the M44 and the M50 engines. On the M44, you may need to hold the tensioner in the retracted position with a drill bit or hex tool through the hole in the front of the tensioner. The belt tensioner is automatic so no tightening is necessary. Best of luck!

I have a very loud squealing noise in my 2003 mazda mvp engine when i accelerate. We removed the belts which would eliminate belts as the problem. And that's that it. If anyone has any info please let me know.
Thank you
