Mechman high output alternators · Authorized dealer
The XTS earned a long second career in executive and livery service, where a sedan spends hours idling with phones charging, climate running and rear passengers using every outlet. This Cadillac XTS high output alternator collection lists three Mechman units for the 2013-2019 3.6L at 240 Amp, 320 Amp and 370 Amp.
A car-service XTS can sit at curbs and airports for much of the day with the engine idling, the climate system working hard and every charging port in use. That pattern is tough on an alternator, because low engine speed and high load arrive together. A Cadillac XTS high output alternator keeps the battery topped up between fares and stops the voltage dips that trigger warning messages.
Private owners have their own reasons to upgrade. Replacing or expanding the factory audio with outboard amplifiers and a processor turns the large cabin into a capable listening room, and it adds a steady draw on top of the car's electronics.
The 240 Amp unit suits livery use and light audio upgrades. The 320 Amp unit covers multi-amp systems, and the 370 Amp unit leaves room for heavy audio plus a second battery. These Mechman high output alternators share their 3.6L series with crossovers such as the Buick Enclave and Chevrolet Traverse. Confirm your 2013-2019 model year and engine in the vehicle finder above the products.
See other models on the Cadillac alternators page, and add a stronger battery from our batteries collection for idle-heavy duty.
