The exact firing order for a Dodge Charger with a 3.5-liter engine isn’t universal; it depends on the specific 3.5L V6 variant and model year. To be sure, identify the engine code and consult the correct service information for that engine.
In practice, Chargers have used more than one 3.5-liter V6 configuration over the years, and each variant may have its own firing sequence. Because the firing order is tied to the engine design, assuming a single sequence can lead to misfiring or damage during maintenance. The following sections explain how to determine the right order for your car.
Identify the exact 3.5L V6 powering your Charger
Use these steps to confirm which 3.5L V6 you have, since the firing order changes by variant.
- Check the vehicle’s VIN and window sticker or build sheet for engine details.
- Look for an engine code stamped on the engine block or near the intake manifold; this code identifies the exact family and version.
- Cross-check features such as valve configuration (SOHC vs DOHC) and cylinder head design against factory manuals or official Mopar documentation to narrow the variant.
With the engine variant identified, you can search for the exact firing order in the factory service manual or a credible automotive database. This avoids guessing and helps ensure a correct, safe repair.
Where to find the firing order for your engine
Once you know the engine variant, use these sources to locate the precise firing order.
- Factory service manual for your engine code—this is the authoritative source for the firing sequence and cylinder numbering.
- Mopar/Chrysler technical manuals or official repair databases (Alldata, Mitchell1, etc.) that publish engine-specific firing orders.
- Vehicle-specific online resources and forums where owners reference your exact engine code and model year, verified against official documentation.
- If you cannot access manuals or databases, consult a qualified mechanic or dealer service department with your VIN so they can pull the correct firing order for your 3.5L V6 variant.
In short, the firing order is tied to the engine code. Do not rely on a single sequence across years or variants; always verify with the correct specifications for your charger’s exact 3.5L V6.
Tips for safely handling ignition work on a 3.5L Charger
Beyond knowing the right firing order, follow best practices to avoid damage or injury during maintenance.
- Disconnect the battery before working near ignition components to avoid shorts or shocks.
- Label spark plug wires and coils if you’re removing multiple components to prevent misrouting during reassembly.
- Use the correct torque specifications when reinstalling spark plugs and ignition coils to prevent thread damage or coil failure.
- Double-check timing marks or a timing light setup only after confirming the precise firing order for your engine variant.
Following these steps helps ensure that you maintain engine reliability and avoid common mistakes when dealing with the firing order of a 3.5L Charger.
Summary
The 3.5 Charger does not have a single, universal firing order. Accurate sequencing depends on the exact 3.5L V6 variant and model year. Start by identifying the engine code (via VIN, engine stamping, or service documentation), then consult the official manual or reputable databases for the precise firing order. When in doubt, contact a dealer or qualified technician. Always verify the sequence before performing ignition work to ensure proper operation and avoid damage.
