How to remove and install an alternator on Hyundai Sonata?

Unplug the battery lead from the negative post. Remove the drivebelt. Getting to the alternator on these models is hard, and you'll need to remove multiple parts like the engine splash shield. What parts you'll need to remove varies by specific model year. Take out cables from the alternator and air conditioning compressor parts, and push aside the wiring harness. To work on the 2011 and later 2.4-liter engines, we need to take out both the Variable Intake Solenoid actuator and valve. Disconnect the holding screws and simply lift the alternator free of its position. Make sure to show the old alternator when you buy a new one to guarantee the parts match exactly. Ask at the shop if they'll move the missing pulley from your old alternator to your replacement. Installation is the reverse of removal. Check twice: After installing the new alternator, fix the belt tension and measure the battery charge to make sure everything works correctly.

Hyundai Sonata Alternator

Hyundai Sonata Alternator is responsible for keeping the car's battery alive and providing steady power to every lamp, stereo, and sensor in operation when the engine is running. The Alternator conceals a stationary stator and a belt-driven rotor in a cast aluminum shell. A pulley-mounted cooling fan blows air over the windings to dissipate heat. As the crankshaft belt rotates the rotor, a magnetic field passes the stator and the Alternator generates alternating current, which is converted to direct current by built-in diodes to charge. Voltage is kept in the safe area due to controlled field current, which is handled by a stand-alone regulator on older Hyundai Sonata models and by the powertrain control module on newer ones. This change allowed the Alternator to lose the additional wiring and to become precise. Across generations of the Sonata, the basic two-piece housing with dual bearings continued, but early units featured external regulators and then control electronics were tucked inside the rear shell, making the Alternator lighter and more compact. Every Hyundai charging unit has the same mission, nonstop electricity for the Sonata.

If you are looking for affordable high-quality OEM Hyundai Sonata Alternator, then you have come to the prime place. Our website provides a large amount of genuine Hyundai Sonata Alternator at unbeatable prices. All our parts come backed with the manufacturer's warranty.
