How to Fix Supercharger Stalling on Your 2025 Dodge Charger

How to Fix Supercharger Stalling

If you're experiencing supercharger issues with your 2025 Dodge Charger, you're not alone. Some owners have reported issues that seem to revolve around the stock oil separator and charging issues. Addressing these issues can help restore your vehicle's performance. As one owner shared, "Twice a month I do a drive that requires 100% charge or stopping, or 80 and stopping in cold weather. I was surprised with precondition how long a supercharger took in cold weather."

Symptoms

Owners of the 2025 Dodge Charger have reported a few key symptoms when experiencing supercharger-related problems. These symptoms can be subtle at first, but they tend to worsen over time if left unaddressed. Recognizing these signs early can save you time and money in the long run.

One common symptom is a noticeable rattle coming from the supercharger area. This rattle may be more pronounced at certain engine speeds or under specific load conditions. Another indicator is hesitation during acceleration. This hesitation can feel like a momentary lag or a stutter when you press the accelerator pedal, especially when the supercharger is expected to provide a boost.

Some owners have also noticed stains or residue around the supercharger and oil separator components. These stains might indicate a leak or excessive oil buildup in the system. An idle issue is another potential symptom. The engine might idle roughly, stall, or fluctuate erratically, particularly after the supercharger has been engaged.

These symptoms, while varied, often point to underlying problems related to the supercharger's performance. It’s important to note when and how these symptoms occur. This can aid in diagnosing the root cause of the supercharger issues.

Most Likely Cause

Based on owner reports, the most likely cause of supercharger stalling in the 2025 Dodge Charger is related to the stock oil separator. The stock oil separator is designed to prevent excessive oil from entering the intake manifold, which can lead to various performance issues. However, in some cases, the stock oil separator may not be efficient enough. This can allow oil to accumulate in the supercharger system.

Excessive oil in the supercharger can lead to a decrease in its efficiency. This can cause hesitation, rough idling, and even stalling. Over time, the accumulated oil can also damage the supercharger components, leading to more significant problems. Therefore, upgrading or maintaining the oil separator is crucial to prevent these issues.

The oil separator's inefficiency can be exacerbated by factors such as driving habits, engine condition, and environmental conditions. Frequent high-performance driving or a poorly maintained engine can increase the amount of oil that makes its way into the supercharger system. By addressing this issue, you can significantly improve the performance and reliability of your 2025 Dodge Charger.

How to Diagnose

Diagnosing supercharger stalling in your 2025 Dodge Charger involves a systematic approach to identify the root cause of the problem. Start by visually inspecting the supercharger and surrounding components. Look for any signs of oil leaks, stains, or damage. Check the connections and hoses leading to and from the supercharger to ensure they are secure and in good condition.

Next, examine the stock oil separator. Check for any signs of cracks, leaks, or excessive oil buildup. Remove the oil separator and inspect it internally. Clean it thoroughly and check for any blockages. If the oil separator is severely clogged or damaged, it may need to be replaced.

To further diagnose the issue, you'll need a few basic tools. A socket set, wrench set, screwdrivers, and a flashlight are essential. A scan tool can also be helpful to check for any error codes that might be related to the supercharger or engine performance. If you are comfortable doing so, you can also perform a boost leak test to check for any air leaks in the supercharger system.

Step-by-Step Fix

Here’s a detailed guide on how to address supercharger stalling issues, focusing on the stock oil separator. Remember to always prioritize safety and consult a professional mechanic if you're not comfortable performing these steps yourself.

1. Gather your tools and parts: You'll need a socket set, wrench set, screwdrivers, new oil separator (if replacing), and clean rags.
2. Locate the stock oil separator: The oil separator is typically located near the supercharger, connected to the intake manifold and crankcase.
3. Disconnect the hoses: Carefully disconnect the hoses attached to the oil separator. Use pliers if necessary to loosen any clamps.
4. Remove the oil separator: Unbolt or unscrew the oil separator from its mounting point. Be careful not to spill any oil that may be trapped inside.
5. Inspect the oil separator: Examine the oil separator for any signs of damage, cracks, or clogs. Clean it thoroughly with a solvent or replace it if necessary.
6. Install the new or cleaned oil separator: If replacing the oil separator, install the new unit in the same location. Ensure it's securely mounted.
7. Reconnect the hoses: Reconnect the hoses to the oil separator, making sure they are properly seated and clamped.
8. Start the engine: Start the engine and let it idle for a few minutes. Listen for any unusual noises or leaks.
9. Test drive: Take the vehicle for a test drive to see if the stalling issue has been resolved. Monitor the engine performance and check for any warning lights.

As one owner shared: "I've got the truck all torn apart doing major maintenance before it becomes the daily driver again. Before parking it, the power was dropping off a fair bit."

Parts and Tools Needed

• Socket set
• Wrench set
• Screwdrivers
• New oil separator (Part number varies depending on the specific model and year)
• Clean rags
• Pliers
• Solvent for cleaning

Real Owner Costs

The cost of fixing supercharger stalling can vary depending on the specific repairs needed and whether you choose to do it yourself or take it to a professional mechanic.

DIY: Replacing the stock oil separator yourself can cost between $50 and $200, depending on the brand and quality of the replacement part. Cleaning the existing oil separator only requires some solvent and a few hours of your time.

Professional Mechanic: If you opt to take your 2025 Dodge Charger to a mechanic, the cost will likely be higher. Labor costs can range from $100 to $300, depending on the complexity of the repair and the hourly rate of the mechanic.

• Example 1: An owner reported spending $150 on a new oil separator and $20 on cleaning supplies, fixing the issue themselves.
• Example 2: Another owner paid a mechanic $400 for diagnosis and replacement of the oil separator, including parts and labor.

Prevention

Preventing supercharger stalling in your 2025 Dodge Charger involves proactive maintenance and careful attention to your vehicle's performance. Regular maintenance of the stock oil separator is crucial. Inspect and clean the oil separator every 30,000 miles.

Avoid frequent high-performance driving, as this can accelerate the wear and tear on the supercharger system. Ensure that your engine is properly maintained, with regular oil changes and tune-ups. Use high-quality oil and filters to minimize the amount of oil that makes its way into the supercharger system.

Consider upgrading to a more efficient oil separator. These aftermarket units are designed to provide better oil separation and prevent excessive oil buildup in the supercharger system. Also, monitor your vehicle's performance closely. This includes listening for any unusual noises, watching for signs of hesitation or rough idling, and checking for oil leaks or stains. Addressing any issues promptly can prevent them from escalating into more significant problems.
