The GAZelle car in our country is the most demanded commercial vehicle. In this regard, it is constantly in operation, which leads to breakdowns. One of the most common is damage to the water pump and generator drive belt. This malfunction is signaled by a special whistle from under the hood. Every motorist can replace it.
It is necessary
- - keys for 10, 12, 13;
- - a knob or an assembly blade.
Instructions
Step 1
Park the vehicle on a level surface and block the wheels. Open the hood. Disconnect the negative terminal from the storage battery. Remove the front panel and radiator grille. To do this, take a 12 key and unscrew two bolts each on the right and left side of the panel. Using a 10 key, unscrew one bolt under the hood lock and remove the two bolts that hold the decorative grille from below. Although the operation to replace the pump and generator drive belt on the ZMZ-402 engine is not difficult, difficulties may arise due to the tightness of the space under the hood. When working, it is better to use gloves so as not to injure yourself on sharp corners or a cold motor.
Step 2
Remove the front panel and grille from the car and place it side by side at a distance that will allow the bonnet lock cable. Take a 12 key and loosen the belt tensioner bolt on the generator. Slide the generator towards the engine with a suitable knob or blade. The belt will loosen. Take the keys 12 and 13 and loosen the lower nut of the tensioner pulley, and then loosen the nut of the tensioner with a key 13.
Step 3
Slide the roller towards the motor. Remove the fan belt from the crankshaft pulley by threading it between the fan blades and turning it. Also remove the water pump belt. Install new belts, front panel and radiator grille in reverse order. In this case, it is possible not to tighten the lower middle bolt of the panel, since the strength of the remaining ones is sufficient. The deflection of the water pump and generator drive belt when pressing on it with a force of 4 kgf should be 8-10 mm. Connect the negative terminal to the battery and start the engine. Give the generator the maximum load - turn on the high beam, heater, car radio and press the accelerator. The characteristic "whistle" of the alternator belt should not be heard.
