You may already know this, however the alternator is a determining factor in an engine. He himself is responsible for transforming energy the engine of your Toyota I-unit in Electricity supply in order to recharge the battery. If there is ever a problem, this could cause most of the electrical failures. It is therefore crucial to pay attention to it. However, the malfunction could also come from its belt, sometimes pulleys. We will see in this guide where will be able to come problems according to the noise that comes out.
Noise alternator belt on a Toyota I-unit
La alternator belt, also known as an accessory belt, is the main element that contributes to the proper functioning of the alternator. It is it which by its rotation takes the alternator and will create electricity. However, it also serves to operate different pumps of the motor. In the event that it breaks, it can cause damages really important in the engine of the Toyota I-unit.
A metallic noise on the Toyota I-unit:
This is a noise that generally comes Cold. The most common cause is that some of the streaks in the belt are damaged. However, it can also happen if the pulley is very slightly offset. If the belt gets loose, it can of course break. If it happens that you recognize this sound, the best thing will be to replace the belt and the malfunction will be repaired almost without fail.
A sharp squeal on the Toyota I-unit:
This remains the most common dysfunction, but also the least serious. It usually comes from cold, but may reappear even when hot at times. Nevertheless, it stops quickly. This inconvenience generally comes from the case where the accessory belt is slack. It will suffice tender and it's done. Be careful, when it stays in this situation for too long, the belt may deteriorate and cause a more dramatic problem in the end. This sharp noise also appears sometimes when the damper pulley happens to be deteriorated, nevertheless it is less frequent.
A slight hiss or breath on the Toyota I-unit:
It is the opposite of the dysfunction of before. The strap is likely to be far too tight or too short. You know what you have left to do !
Alternator noise on a Toyota I-unit
When it is really the alternator which produces this sound and not the belt, in this situation the problems are totally divergent. However, the sound you hear may have some resemblance to that of a strap, i.e. a high hiss. The concern may arise from a electrical failure, this remains relatively frequent. In case the voltage useful for the proper functioning of this Toyota I-unit remains low, this is generally seen in the lack of intensity of the indicator lights or bulbs inside your automobile. Assuming that the intensity intensity is excessive, it is possible that the battery indicator stay on. If you want to make a real diagnostic of this concern, it is possible to use a voltmeter and to check the tension on the + and minus of your battery, the ignition on of course. Assuming that the voltage is lower than that recommended by the battery, the malfunction can therefore come from the alternator. In this situation, it usually needs to be replaced.
Conclusion:
An alternator sound generally comes from the alternator belt, but may also come from the alternator itself. Economically, an alternator belt costs considerably less than the alternator. Ask for an estimate at a auto repairer before embarking on repairs, simply because we are not necessarily sure of the cause of the malfunction. We hope that this post served you something, if it is the case do not hesitate to post a comment. Have a good trip with your Toyota I-unit.
