Alternator is one of the vital parts in any gasoline-powered vehicle, without it, the car will not be able to function effectively. Functioning similarly to a generator, it works with the car battery to power the electrical systems while the engine runs. If you would like to learn how to replace your Volvo alternator, read on as we share some tips to help you along the process.
1. Getting The Right Parts
Choosing the right parts for your car is the first step, it will not work if you choose a budget part and it does not fit into your car. It will be most helpful if you know the specific part number or the specifications. Alternatively, you can search for the Volvo car model and it should advise you on the right part, for instance, the alternator required for Volvo V60 is a 2 liter alternator with part number: 36002812.
2. Disconnect Car Battery
Ensure that you have disconnected your vehicle’s negative battery cable before you start replacing the alternator for safety purposes and preventing potential damage to the electrical circuit. After finding the right socket to loosen the bolt on the battery terminal with a visible negative (-) sign, you may proceed to slide the cable off the terminal when it is loose. Move the connector out of the way so that it does not move back and have contact with the battery during the process.
3. Remove The Belt
To remove the serpentine belt, you first have to identify the belt tensioner and using either a belt tensioner tool or a wrench, loose it. The belt tensioner is spring-loaded and it keeps the belt tight so be especially careful not to injure yourself when you proceed to loosen it. It is important that you remember the belt’s routing, it may help if you equip yourself with a belt routing diagram or take a detailed photo or video to help you later when you try to fix it back.
4. Remove Wires From Alternator
Again, it is vital that you remember the attachments of the wires before you remove the wiring harness, connectors and fasteners. Label the wires to facilitate the installation of the new alternator.
5. Installing New Alternator
Check that your new alternator fits properly into where the previous alternator seats and aligns with the existing bolts by reversing the steps above. Ensure that as you assemble the new alternator, you have accurately fitted in the wires and all wires are fastened as labelled.
6. Running The Belt Over New Alternator
Before you install the belt over the new alternator, ensure that the belt is not worn out or has any cracks on it. Follow the routing diagram or the photo you took previously and refit the belt over the new alternator. Check for the correct belt tension.
7. Reconnect The Battery
Reconnect the negative battery terminal and do a last visual check that everything is in place before you start the engine to test out your new alternator. Check that the belt and all pulleys are turning in place as the engine runs. If all is well, you have succeeded in changing your alternator!
