Mazda 3 Service Manual: Drive Belt Removal/Installation [Mzr 2.0, Mzr 2.5]

MZR 2.0

A/C drive belt removal

1. Remove the aerodynamic under cover No.2 and splash shield as a single unit..

2. Remove the nut shown in the figure and set the power steering pipe component out of the way.

3. Set the SST

as shown in the figure.

NOTE:

• Hold the SST

  by hand until it fits between the A/C drive belt and the crankshaft pulley.

4. Rotate the crankshaft pulley clockwise using a wrench and remove the A/C drive belt.

A/C drive belt installation

1. Set the SST

to the crankshaft pulley as shown in the figure.

NOTE:

• Hang the A/C drive belt on to the A/C compressor pulley, then move the SST

  upward along the crankshaft pulley.

2. Set the SST

to the A/C compressor mount as shown in the figure.

NOTE:

• During the A/C drive belt installation, if the SST

  touches the part number-printed area on the back of the A/C drive belt, the SST

  may not be able to slide smoothly and the A/C drive belt will be pulled inward excessively. This will make it impossible to correctly install the A/C drive belt to the groove of the A/C compressor pulley. To prevent this, adjust the A/C drive belt to the position shown in the figure, then start the procedure.

3. After setting the SST

, verify that the three parts of A/C drive belt shown in the figure are hung on each pulley.

4. Rotate the crankshaft pulley clockwise using a wrench and install the A/C drive belt.

CAUTION:

• Remove the SST (49 B015 103) immediately after it reaches the lower side to prevent it from falling down and being damaged.

5. Remove the SST (49 B015 104)

.

6. Rotate the crankshaft pulley clockwise one time or more to verify that the A/C drive belt is installed correctly.

CAUTION:

• Do not turn the crankshaft pulley counter clockwise, otherwise the crankshaft pulley bolt could loosen and the timing could change causing engine damage.

• If the A/C belt is not seated properly, push/pull the belt with a suitable tool in the direction where it would be seated properly and then rotate the crank pulley clockwise until the belt is correctly seated. If this does not correct the problem, remove the belt and install it again.

7. Install the nut shown in the figure.

8. Install the aerodynamic under cover No.2 and splash shield as a single unit..

Generator drive belt removal

1. Remove the A/C drive belt..

2. Turn the center of the auto tensioner pulley counterclockwise to release tension to the drive belt tension.

3. Remove the generator drive belt.

Generator drive belt installation

1. Install a generator drive belt.

2. Install the A/C drive belt..
