About this part
The alternator on your CTS Sigma II charges the battery and powers the electrics while the engine runs. A failing alternator causes dimming lights, a dying battery and eventually a vehicle that won't start.
Frequently asked questions
What should I check when ordering a replacement alternator for the Cadillac CTS?
Match the exact engine code and the model year of your CTS Sigma II, as alternators differ in output (amps) and mounting. Check whether the pulley is included or needs to be transferred.
Is a remanufactured alternator a good option?
Yes – remanufactured alternators are tested to OEM specs and are often significantly cheaper than new. They're a reliable and economical choice for most vehicles.
