Functioning and various information

Function of a starter motor on Volvo S90

The starter motor is an electric motor whose single function is to start the engine motor of your vehicle. By a magnetic system and a “serial” technology, it will launch an enormous torque that will allow it to drive the pistons of the engine that are subjected to enormous compression and an oil that provides additional resistance being not very fluid when cold.
It is completed by the “solenoid”. It is an electromagnet that goes under a 12 volt electric impulse to push the fork (link element between the “solenoid” and the electric motor of the starter) and thus engage the starter drive pinion on the engine flywheel. Following this action, once in engagement, the starter motor of your Volvo S90 is activated and turns the drive pinion on the flywheel to start the engine.

How to avoid starter motor noises on Volvo S90

  • Do not try to start your engine for too long
  • Even if your engine does not start because of tired glow plugs, for example, or because the weather is too cold. You should not turn your key for more than a few seconds or you will burn it. Indeed, the current necessary to make it turn and the speed of rotation only allows it to perform its function over very short and intense periods of time. If the vehicle does not start, look for the solution somewhere else.

  • Do not use a starter motor on Volvo S90 with a tired battery
  • Although when you have a battery that is empty, you always want to start your vehicle, the energy it is capable of holding may not be sufficient to provide the power demanded by the starter motor to start your engine motor. Repeated attempts will pre-use your starter motor and if you do not resolve the cause of your failure to start repeatedly, your starter may be the future element you will have to replace.
