Toyota Alternator Problems

How to change the alternator belt on a four-cylinder engine?The power steering belt needs to be removed to get to the alternator belt in a four-cylinder engine. To reach the power steering belt, find the 14mm nut right in the center of the idler bearing or tensioner bearing bolted to the front of the cylinder head and loosen it. A 12mm bolt known as the pinch bolt that goes through the bracket into the top of the alternator needs to be loosened and the belt needs to be pulled in order to bring the alternator towards the engine. If this becomes difficult to move, the 14mm pinch bolt that goes to the bottom of the alternator needs to be loosened. This allows enough slack to remove the alternator belt and makes the alternator rotate towards the engine. When belts need to be reinstalled, the process is reversed by taking out the alternator, tightening the bolt and reinstalling the power steering belt.
What could cause the alternator belt to need replaced 3 times on a 1989 Toyota Camry?The issue could be usage of a low end 55 amp alternator that was used for replacement as the internal regulator most likely burns up from heat. The best option would be to use an upgraded 100 amp alternator whenever an alternator needs to be replaced. It would be advisable to also check the wires from the alternator to the battery and visually ensure they are in good form.
How to remove the alternator on a 2006 Toyota Highlander that keeps rotating up and down on the motor mount?Using a screw driver the sleeve needs to be pulled out of the mount where the alternator is pivoting as it is this sleeve that is keeping it in position. When replacing the alternator with a new one, it would be best to lightly tap on the sleeve to make it push in a little to facilitate the alternator to slide back in. When the bolt is tightened, the sleeve would be pushed back out.
How to remove a fusible link (100 amp alternator) from a 2003 Camry?First, the lock tabs need to be pulled out in order to let the plastic panels unsnap. The inner sub panel/ plug also have lock tabs that lift up out of the main panel. Along the inside of the box the lock tabs need to be located and by fiddling with the panel up and down, the tabs need to be located. The panel needs to be popped loose to enable the fuse box to be taken out in order to give way for the wires to be flexed to the box. Using screw drivers would help while fixing this. Two bolts, one from either side bolts the fuse spades to the buss bar. Both the fuse box and the sub box need to be disassembled as once the bolts are removed, the fuse comes out easily.
What could be the issue if after replacing the alternator fuse of a 2002 Camry the car doesn’t start, the windows don’t work and neither do the tails lights?The first thing would be to ensure the fuses are getting in power and giving out power. Use a volt meter to check for current flow as in certain cases the fuse box burns internally and so there could be no power to a fuse even if the fuse has not blown up. Start with the fuses under the hood, then move to those under the dash and ensure all the fuses have 12v of power getting in and out of them. In most cases, the issue is with the fuses, at times it could burn the fuse box and at other times it could also affect the alternator and ignition switch. Each case and situation is different as it depends on how long the short lasted, if the key was with the ignition on or if the ECU was burned out.
Alternators have more advantages over DC generators as they are lighter and more affordable. Automotive alternators are usually belt driven at 2-3 times crankshaft speed. They drive at different RPMs as they are driven by engines and alternating current is rectified to direct current. Complex terminology and functioning of an alternator may be difficult to understand and comprehend. Therefore, when questions arise, turning to an Expert for help may prove to be useful.
