Note: The specific routing and tensioner location may vary depending on the year, model, and engine type of your Montero.
Here are the general steps for replacing an alternator belt on a Montero:
1. Park your vehicle on a level surface, apply the parking brake, and turn off the engine.
Allow the engine to cool if it has been running. Disconnect the negative terminal of your battery to avoid any electrical hazards.
2. Locate the alternator belt.
It is usually located on the front side of the engine, wrapping around the crankshaft pulley, water pump, and alternator pulley.
3. Release the tension on the belt.
To release the tension, locate the belt tensioner. This is usually a pulley or mechanism with a movable arm. Refer to your vehicle's repair manual for the specific location of the tensioner. Once you've found the tensioner, use a wrench or lever to release the tension on the belt.
4. Remove the old belt.
Once the tension is released, you should be able to remove the belt by simply pulling it off the pulleys.
5. Install the new belt.
Align the new belt with the grooves of the pulleys, starting with the crankshaft pulley. Make sure that the belt is routed correctly according to the diagram.
6. Reapply tension to the belt.
Use the belt tensioner to reapply tension to the belt. Refer to your vehicle's repair manual for the correct tension specification.
7. Reconnect the battery's negative terminal.
8. Test the belt tension and alignment.
Start the engine and let it run for a few minutes. Observe the belt's movement and check that it's properly aligned and not slipping. Adjust the tension if necessary.
9. Test drive the vehicle.
Take a short test drive to ensure that the belt is functioning correctly and the alternator is charging the battery.
Remember, this is a general guide, and the specific steps may vary depending on your vehicle model. If you're not comfortable performing this task yourself, it's always a good idea to consult with a qualified mechanic or refer to your vehicle's specific repair manual for more detailed instructions.
