Checking and replacing the accessory drive belt

            0

Checking the accessory drive belt is performed as follows.

1. Remove the right front wheel.

2. Remove fender liner (see Removal and installation of wheel mudguards and fender liner.



3. Check belt tension. A properly tensioned belt should rotate 90°with finger force 15–20 N (1.5–2 kgf). If the belt is loose (stretched during use), it needs to be replaced.

4. Check the condition of the belt by visual inspection. If the belt shows signs of severe wear or is oily, it must be replaced.

NOTE: A sign of wear on the multi-ribbed belt is a change in the shape of the ribs on the running surface. The new belt has trapezoidal ribs in cross section, while the worn belt has acute-angled ribs.


5. Install the parts in the reverse order of removal.

Replacing the 1.6L Duratec Ti-VCT accessory drive belt is as follows.

NOTE: As recommended by the manufacturer, the accessory drive belt (alternator, water pump and power steering pump) must be replaced every 60 thousand km or 6 years of operation (whichever comes first).


You will need: an 8 socket, a 19 key, a special tool for installing a belt, a knife.


1. Hang the front of the car and place on a secure support. Remove the right front wheel.

2. Remove the right front fender liner (see Removal and installation of wheel mudguards and fender liner).

3. Remove the protective casing of the auxiliary drive belts and the air conditioning compressor by unscrewing the bolts of its fastening to the engine with the "8" socket head.

4. Remove the A/C compressor drive belt.

NOTE: According to the manufacturer's recommendations, the accessory drive and A/C compressor drive belts should be cut with a knife for removal, after which they become unusable. This is due to the fact that both belts, even after being removed without damage, cannot be reused, since they are designed only for one-time stretching when installed on pulleys (belt tension adjustment is not provided). In addition, the replacement of belts is regulated after a certain mileage or service life, therefore, when replacing the accessory drive belt, the air conditioning compressor drive belt should also be replaced at the same time.


5. Remove the accessory drive belt by cutting it with a knife.

6. Wipe the pulleys of all units with a clean rag to prevent slippage of the accessory drive belt during installation.

7. Install the new accessory drive belt on the crankshaft, water pump, and power steering pump pulleys so that the belt is in the center of the pulley grooves. Install the tool on the water pump pulley in the position shown in fig. 5.13 by pressing it until it clicks, which means that the device is fixed on the pulley.


WARNING: Make sure the accessory drive belt mount retainer snaps into place on the pulley and securely secures the accessory. Otherwise, the belt will be damaged during installation.

8. Remove the belt from the water pump pulley and install it on the alternator pulley.

Turn the belt mounting tool counterclockwise to the position shown in fig. 5.14, and put the belt behind the foot of the device.

WARNING: Make sure that the belt is correctly installed on the mounting tool, otherwise it will be damaged during installation.



9. Engage 1st gear in a manual transmission (or set the automatic transmission selector to position "P" - parking) and brake the vehicle with the parking brake to prevent the engine crankshaft from turning.

10. Turn the belt mounting tool by the bolt installed in it clockwise (pic. 5.15) until the belt is installed on the water pump pulley (at this point, the belt tension will loosen).

WARNING: Make sure that the mounting tool is not caught between the belt and the water pump pulley, otherwise the belt will be damaged.

11. Using a large screwdriver or spudger, slide the mounting tool off the water pump pulley against the resistance of its lock.

12. Set the transmission lever to neutral position.

13. Turn the crankshaft with a "19" key for the bolt securing its pulley by about 90°to such a position that the mounting device is not clamped by the belt, and remove it.

NOTE: Accessory drive belt mounting tool is disposable as it deforms during installation.


14. Turn the engine crankshaft two turns and check that the belt is correctly positioned in the pulley grooves. Reinstall the belt if necessary.


15. Install the A/C compressor drive belt.

16. Install the parts in the reverse order of removal.

Replacing the accessory drive belt on 2.0L and 2.3L Duratec-HE engines is as follows.

NOTE: As recommended by the manufacturer, the accessory drive belt (generator and water pump) must be changed every 60 thousand km or 6 years of operation (whichever comes first).




This is how the auxiliary drive belt is located on the engine.

You will need: socket heads "for 8" and "for 21", a special tool for installing a belt, a knife.

1. Hang the front of the car and place on a secure support. Remove the right front wheel.

2. Remove the right front fender liner (see Removal and installation of wheel mudguards and fender liner.

3. Remove the protective casing of the auxiliary drive belts and the air conditioning compressor by unscrewing the bolts of its fastening to the engine with the "8" socket head.



4. Remove the A/C compressor drive belt by cutting it with a knife.
