Chrysler 300 (2005-2014) Power Steering Pump Replacement Overview
Experiencing whining noises or stiff steering in your Chrysler 300? Here’s what you need to know about replacing your power steering pump.
- A whining noise that changes pitch when you turn is the most common symptom of failure.
- Use the correct fluid, which is often ATF+4, not generic power steering fluid.
- 2011 and newer models use an Electro-Hydraulic (EHPS) pump located in the wheel well, which is different from earlier models.
- Check for a leaking power steering pressure hose, which was subject to a recall on 2010 models.
Is Your Chrysler 300 Power Steering Pump Failing?
A failing power steering pump is a common issue as a vehicle ages. In the Chrysler 300, the first signs of trouble are often audible. If you hear a distinct whining or groaning noise from the engine bay that gets louder when you turn the wheel, your pump is likely crying for help. This noise is often caused by low fluid or a pump that is starting to wear out internally.
Key Symptoms of a Bad Pump:
🎬 Watch this guide to identify common signs of pump failure.- Whining or Groaning Noises: The most common symptom. The noise pitch often increases with engine RPM or when turning the wheel.
- Stiff or Heavy Steering: If turning the wheel suddenly feels like a workout, the pump is no longer providing adequate hydraulic assistance.
- Fluid Leaks: You may notice reddish or brown fluid puddles under the front of your car. Low fluid can quickly damage the pump.
- Jerky or Erratic Steering: The steering wheel might feel like it's vibrating or providing inconsistent assistance as you turn.
Generation Differences Matter
The power steering system changed significantly between the first and second generations of the Chrysler 300. The 2005-2010 models use a traditional belt-driven hydraulic pump. The 2011-2014 models often use an Electro-Hydraulic Power Steering (EHPS) system. This system has its own set of potential issues, including electrical faults with the pump motor or control module. It's crucial to identify which system your car has before ordering parts.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
There have been some official communications regarding the power steering systems on these vehicles.
- NHTSA Recall 10V475000 (K26): This recall affected some 2010 Chrysler 300 models. It addressed a potential separation at the crimped end of the power steering pressure hose, which could lead to a fluid leak and a potential fire hazard if the fluid contacted hot engine components.
- NHTSA Recall 17V-435: This recall impacted some 2011-2014 Chrysler 300 vehicles equipped with EHPS. The issue was related to alternator diode failure caused by the cyclical loads from the EHPS system, which could lead to a vehicle stall. While not a direct pump failure, it highlights the electrical demands of the EHPS system.
Owners have also reported issues with the EHPS pump blowing fuses, sometimes due to corroded wiring or high current draw when turning the wheel at a standstill.

When your original Mopar pump fails, you have several options. The quality and price can vary significantly.
OEM (Mopar): This is the original part your car was built with. It offers guaranteed fit and performance but comes at the highest cost. If your budget allows, it's the most reliable choice.
New Aftermarket (A.A.E., Mapco): Brands like Atlantic Automotive Enterprise (A.A.E.) offer new pumps that are designed to meet or exceed original specifications. These are often a good balance of quality and cost, avoiding the potential pitfalls of remanufactured parts.
Remanufactured (Cardone, BBB Industries): Remanufactured pumps are original units that have been rebuilt with new seals and tested components. Brands like Cardone are widely available and budget-friendly, but quality can be inconsistent. While some have good experiences, others report premature failures. BBB Industries is another common remanufactured option. A remanufactured pump can be a cost-effective solution, but be prepared for the possibility of needing to use the warranty.

Frequently Asked Questions
What kind of fluid does my Chrysler 300 power steering use?
Many Chrysler 300 models, particularly the first generation, specify ATF+4 transmission fluid for the power steering system, not standard power steering fluid. Using the wrong fluid can cause noise and damage the pump. Always check your owner's manual or a reliable service guide for your specific year.
Where is the power steering pump located on a Chrysler 300?
On earlier V6/V8 models, the pump is typically belt-driven and located on the front of the engine. On later models with the EHPS system (2011+), the pump and reservoir are often located in the front passenger-side wheel well, behind the fender liner.
🎬 See how to replace the electric pump on 2011-2014 models.Is a remanufactured pump a good choice?
It can be, but it's a gamble. Remanufactured pumps from brands like Cardone or BBB Industries are significantly cheaper. However, their quality can be inconsistent. If you choose a remanufactured part, buy from a vendor with a good warranty and return policy.
Do I need to replace the reservoir or pulley with the pump?
Many new and remanufactured pumps come with the reservoir and sometimes the pulley already installed. If your chosen pump does not, you will need to transfer them from your old pump. It is often recommended to replace the reservoir to prevent contamination from old fluid and debris.
