The starter in GMC Acadia cars is one of the parts which transforms the electric energy of the battery in mechanical energy for cranking the engine. Starting is done by a solenoid which is in contact with the battery; this makes the starter motor work. In the starter assembly there is an armature that through electromagnetic means rotates creating engagement with the starter drive and hence turning the engine's flywheel or the flexplate ring gear. The most widely applied starters can be observed on GMC Acadia vehicles, and they are electric starters. These starters have a solenoid that pulls an arm that engages a drive pinion with the flywheel of the engine, an overrunning clutch that disengages the drive once the engine has started. In the years past, in an effort to increase efficiency and minuteness, improvements, such as gear-reduction systems added. For regular engines, OE starters are competent; however,mods which include the use of high compression engine will require denser starters to avoid challenges such as kick back or starter breakdown. This difference is essential for durability and performance of the GMC Acadia's engine in the long run.
