How to remove and install an alternator on Volkswagen Golf?

Other alternators might contain a one way clutch, which is necessary to be hand-overed to the new alternator. To start with, unconnect the cable at the negative battery contact and take off the engine cover. On four-cylinder models starting with 2014, raise and support the front of the vehicle on jackstands, next remove the air inlet hoses and turbocharger charge air pipe on turbocharged vehicles. In non-turbocharged models, eliminate the air filter housing. Second, take off the drivebelt, loosen the coolant pipe mounting bolts in turbocharged type, take off the air conditioning compressor in 2.0L turbocharged type. Disassemble the cal connectors off the alternator, pull off the mounting fasteners and exchange the alternator. On models afterwards and 2015, remove the EVAP canister (where applicable), make sure that the alternator mounting bushings are not blocked, and elevate the front of the car (and support it) using a jack. In 1.4L engines, disconnect the hose to the lower coolant, auxiliary pump to coolant, disconnect the drivebelt, hold the air conditioning compressor and take out the mounting bolts to the alternator. To get to the electrical connectors, rotate the alternator, unplug them and pull out the alternator. In Jetta, 1.8L and 2.0L 2015-2017, loosen the bolts of the coolant pipe and unscrew the oil pressure switch (where applicable) and unscrew the alternator in the same way. To remove the existing turbocharger piping and add the new turbocharger piping in Golf 1.8L or 2.0L engines or Jetta 2.0L engines (2018 and later), first remove engine cooling fans, drivebelt, upper alternator bracket bolts, and turbocharger piping electrical connector and then remove alternator. With five-cylinder models, lift up the front of the car, take off the air inlet off the radiator support, position the radiator support panel in the service position, take off the drivebelts, tensioners, disconnect the electrical connector of the alternator, remove the mounting fasteners. Removal is the opposite of installation whereby the alternator mounting fasteners should be tightened and the reconnection of the cable to the negative battery terminal is made and the charging voltage should be checked to determine whether it is operating as expected.

Volkswagen Golf Alternator

The Volkswagen Golf Alternator makes the hatchback battery remain charged whilst providing a continuous flow of power to the lights, ignition and its gadgets as the engine operates. The rotor of the device is located in two cast-aluminum shells and spins on permanent copper windings, and a pulley mounted in front of it allows the engine belt to turn the rotor to convert mechanical motion to electricity. When the magnetic field of the rotor passes through the coils of the stator, alternating current is produced and directed to the diodes installed, which convert it into the direct current required by the electrical network of the vehicle. Through generations, Volkswagen put cooling fins on the pulley nose and vented holes on the casing so that fresh air can remove the heat of the diodes and windings. An early Alternator applied an external voltage regulator or a stand-alone internal voltage regulator to maintain the output at approximately fourteen volts to keep the lights bright and the batteries charged, with new Alternator designs taking that task over and adjusting field current dynamically in order to control the voltage more smoothly. Subsequent Golf models use smaller internal brush packs and better heat sinks, and reduce weight, but adjust to increased part loads of infotainment and new safety sensors. The amperage rating might be different in recent units from Volkswagen, but all the designs have one similar objective, which is to convert the movement of the engine into reliable electricity to keep the car starting, running and entertaining. Since the Volkswagen Alternator is connected to the crankshaft by a serpentine belt, a slipping belt or a worn-out bearing is the common fairly simple sign of trouble.

Choose OEM Alternator for superior quality and long-lasting durability. They match the Volkswagen's factory specifications exactly and pass strict quality control. If you plan to replace Alternator on your Golf, put OEM at the top of your list. You'll get the right fit, reliable performance, and peace of mind.

Q: How to remove and install an alternator on Volkswagen Golf?
A:
Other alternators might contain a one way clutch, which is necessary to be hand-overed to the new alternator. To start with, unconnect the cable at the negative battery contact and take off the engine cover. On four-cylinder models starting with 2014, raise and support the front of the vehicle on jackstands, next remove the air inlet hoses and turbocharger charge air pipe on turbocharged vehicles. In non-turbocharged models, eliminate the air filter housing. Second, take off the drivebelt, loosen the coolant pipe mounting bolts in turbocharged type, take off the air conditioning compressor in 2.0L turbocharged type. Disassemble the cal connectors off the alternator, pull off the mounting fasteners and exchange the alternator. On models afterwards and 2015, remove the EVAP canister (where applicable), make sure that the alternator mounting bushings are not blocked, and elevate the front of the car (and support it) using a jack. In 1.4L engines, disconnect the hose to the lower coolant, auxiliary pump to coolant, disconnect the drivebelt, hold the air conditioning compressor and take out the mounting bolts to the alternator. To get to the electrical connectors, rotate the alternator, unplug them and pull out the alternator. In Jetta, 1.8L and 2.0L 2015-2017, loosen the bolts of the coolant pipe and unscrew the oil pressure switch (where applicable) and unscrew the alternator in the same way.
