It may not be unknown to you, however the alternator is a vital component in an engine. He himself is the one who guarantees to transform energy of the engine block of this Toyota Highlander in Electricity supply so as to recharge the battery. If there is ever a malfunction, it can therefore mainly cause electrical failures. It is therefore important to deal with it. However, the problem may also arise from the belt, sometimes pulleys. We will see through this text where the problems selon le noise which is issued.noise-alternator-Toyota-Highlander

Noise alternator belt on a Toyota Highlander

La alternator belt, also known as an accessory belt, is the essential element which contributes to the good action of the alternator. It is it which, thanks to its rotation, takes away the alternator and makes it possible to produce electricity. However, it also serves to train different pumps of the engine block. If it breaks, it could cause damages rather serious within the engine of this Toyota Highlander.

A metallic noise on the Toyota Highlander:

It is a hazard that often arises Cold. The most common source is that the streaks on this belt will be damaged. However, this could also happen as soon as the pulley is a little off-center. In the event that the belt becomes loose it could of course break. If it happens that you can make out this noise, the ideal thing will be to change the belt and the problem will be solved practically for sure.

A sharp squeal on the Toyota Highlander:

It is the most frequent dysfunction, but also the least critical. It usually comes cold, but may come back when you are driving occasionally. However, it suddenly stops. This noise generally comes from when the accessory belt is not tight enough. It is necessary to tighten and it's done. Be careful, in case it stays in this situation too long, the belt could deteriorate and cause a more dramatic concern in the long term. This sharp screech also happens sometimes when the damper pulley happens to be damaged, however it is less common.

A slight hiss or breath on the Toyota Highlander:

It is the opposite of the dysfunction of before. The strap is probably far too tight or too short. You know what you have left to do !

Alternator noise on a Toyota Highlander

Assumed that it is indeed the alternator which creates this noise and not the belt, in this case the problems will be fundamentally divergent. However, the noise you hear may be similar to that of a belt, either high hiss. The problem may arise from a electrical failure, this remains fairly ordinary. If the voltage essential to the good activity of the Toyota Highlander is usually deficient, this is generally seen in the lack of power of the lights or lights in your automobile. Assuming that the lack of power is excessive, it happens that the battery indicator can be running. In order to make a real diagnostic of the problem, it is possible to use a voltmeter and take the tension on the + and - of the battery, with the ignition on of course. If the voltage is found to be lower than that suggested on the battery, the problem could therefore come from the alternator. In this situation, it will usually need to be changed.

Conclusion:

A new alternator noise often comes from the alternator belt, but may also come from the alternator itself. Economically, an alternator belt costs considerably less compared to the alternator. Have a costing done at a auto repairer rather than embarking on repairs, as you can never be certain of the cause of the problem. We hope that this post served you something, in this case do not hesitate to leave a comment. See you soon with your Toyota Highlander.
