Presentation Description

Alternators are typically found near the front of the engine and are driven by the crankshaft, which converts the pistons' up-and-down movement into circular movement. Disconnect the negative battery cable and examine the belt that's connected to the alternator to determine if it's a serpentine belt or a V belt. After loosening the tensioner, loosen and remove the belt, feel free to contact us at PARTSAVATAR CAR INTERIOR & EXTERIOR PARTS, TORONTO our professional mechanics will help you to diagnose and fix it

What is Alternator and How do Replace Alternator at home What is Alternator Alternators are typically found near the front of the engine and are driven by the crankshaft which converts the pistons up-and-down movement into circular movement. Some early model vehicles used a separate drive belt from the crankshaft pulley to the alternator pulley but most cars today have a serpentine belt or one belt that drives all components that rely on crankshaft power. Most alternators are mounted using brackets that bolt to a specific point on the engine. Inspect the Alternator Belt for Damage: One of the most common symptoms of a loose or damaged alternator belt is a rattling noise under the hood of the car while the engine is running. If you hear this noise and determine that the alternator bracket is loose you should first inspect the alternator belt. Installation new alternator:

1. Disconnect the negative battery cable and examine the belt thats connected to the alternator to determine if its a serpentine belt or a V belt.

2. To loosen a serpentine belt first locate the belt tensioner its spring loaded and keeps the belt tight so use caution when working on it being especially careful not to trap or injure your hand when you loosen it and the spring snaps back. 3. After loosening the tensioner loosen and remove the belt. 4. Remove the wiring harness connectors or wiring and fasteners from the alternator. 5. Loosen and remove the alternator. If you have a V-belt the alternator must first be loosened before the V belt can be removed as the alternator provides belt tension. 6. Install the new alternator making sure that it fits properly and aligns with the existing bolt holes 7. Check for the correct belt tension. On an older engine with a V-belt the belt should have no more than about 1/2" of deflection in either direction. 8. Reconnect the negative battery terminal. Attach the voltmeter to the battery and start the vehicle. Check for proper voltage indicated by the alternator output read between 13.1 to 16.5 volts For more error code diagnostic and repair tips feel free to contact us at PARTSAVATAR CAR INTERIOR EXTERIOR PARTS TORONTO our professional mechanics will help you to diagnose and fix it.
