This premium aftermarket replacement voltage regulator is manufactured to meet your expectations for fit, form, and function. Review: Pretty decent - It works well enough. I'm using it to replace a broken regulator in the engine computer. With that in mind, the voltage does tend to fluctuate a decent amount with this regulator, especially under heavy load. The voltage gauge will actually wiggle back and forth when the turn signal is on. Otherwise, i've had no issues with this regualtor, you just have to make sure it has a really good ground on the case or you run a high risk of frying it. Review: Works well, Made in the USA! - I was searching the mopar forums for a reliable voltage regulator and most commented on the reliability of this particular item..( Bonus made in the USA)..and fairly priced as well!! ## Features - professional, premium aftermarket replacement - provides the performance and dependability you expect from acdelco - manufactured to meet expectations for fit, form, and function - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C9QI96 | | Best Sellers Rank | #169,722 in Automotive ( See Top 100 in Automotive ) #22 in Automotive Replacement Alternator Voltage Regulators | | Brand | ACDelco | | Customer Reviews | 4.3 4.3 out of 5 stars (254) | | Date First Available | July 31, 2007 | | Exterior | Painted | | Item Weight | 5.6 ounces | | Item model number | C603Z | | Manufacturer | ACDelco | | Manufacturer Part Number | 12336870 | | Model | ACDelco - Voltage Regulat (B) (C603Z) | | OEM Part Number | 12336870 | | Product Dimensions | 4.7 x 2 x 4.1 inches | ## Images ![ACDelco Professional C603Z (12336870) Current and Voltage Regulator - Image 1](https://m.media-amazon.com/images/I/71e7fNK84oL.jpg) ## Questions & Answers **Q: What are the signs of a failing alternator?** A: Common signs of a failing alternator include dashboard warning lights, electrical issues like overly bright or flickering lights, frequently dying battery, whining, grinding or squealing engine sounds, or stalling or struggling to start the vehicle. **Q: Is the solenoid included?** A: Yes.

At 1/3rd the price of the original equipment model, I chose this as a backup only because they are notorious for dying and leaving people stranded. When my original Mopar unit died, I bought two units; one Mopar branded one made in the US, and this one. I will only use this one as a “just in case” backup unit. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/7646043-acdelco-professional-c603z-12336870-current-and-voltage-regulator](https://www.desertcart.ro/products/7646043-acdelco-professional-c603z-12336870-current-and-voltage-regulator) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-07-06*
