1. Derale Series 7000 Power Steering Cooler Kit
| Material | Aluminum / Copper |
|---|---|
| Core type | Tube and Fin |
| Inlet / Outlet | 11/32 in Hose Barb |
| Finish | Black Powder Coat |
This Derale Series 7000 kit is a small, tube-and-fin power steering cooler intended to lower fluid temperatures and protect the steering system during heavy use. It includes a compact aluminum/copper cooler with 11/32 inch hose barb inlet and outlet plus basic mounting hardware and hose to connect into the steering lines. In practice the unit is mounted where air can pass over the core so it sheds heat effectively; reviewers report significant temperature drops after installation. The black powder-coat finish resists corrosion and the lightweight construction makes it easy to handle during install. Because the core is compact it is simple to fit into tight spaces but will perform best with good airflow rather than passive mounting behind dense obstructions. This is a straightforward, reliability-minded upgrade for vehicles that see towing, long highway runs, or high steering loads, but it is not a heavy-duty radiator replacement and larger coolers are advisable for extreme-duty applications.
Best for: Practical, reliability-focused owners who prioritize protecting steering components from heat during towing, long drives, or frequent heavy steering loads and want a simple, durable add-on.
Less Ideal for: Drivers needing maximum cooling for extreme-duty towing, high-horsepower or continuous track use should consider a larger capacity cooler or multi-pass unit instead.
- Compact tube-and-fin core fits into tight engine-bay locations
- Aluminum/copper construction for efficient heat transfer
- Includes hose barb inlet/outlet and basic hardware for straightforward installation
- Black powder-coat finish provides corrosion resistance
- Small core size limits maximum cooling capacity compared with larger aftermarket coolers
- Requires airflow over the fins to achieve best temperature reduction
Verdict A compact, corrosion-resistant cooler that provides meaningful temperature control for reliability-focused owners but is modest in capacity compared with larger aftermarket units.
2. PartsFlow Power Steering Oil Cooler
| Manufacturer | PartsFlow |
|---|---|
| Material | Aluminum |
| Manufacturer Part Number | IAB-AZA |
This PartsFlow power steering oil cooler is a straightforward replacement-style cooler that regulates steering fluid temperature to reduce wear and overheating. It installs in place of the factory cooler and is intended to sit inline with the power steering lines, where its aluminum core disperses heat more effectively than older steel units. Typical use is as a direct-fit upgrade to restore cooling performance after a failed cooler or to preempt overheating in heavy towing or hot-climate driving. The visible advantages are corrosion resistance from the aluminum construction and OEM-style mounting that helps the bolts and ports line up for an easier install.

Choosing the Right Chevrolet Traverse Power Steering Cooler: Key Factors to Consider
Cooling Capacity And Core Size
Cooling capacity determines how effectively a unit reduces steering fluid temperature during sustained or heavy steering loads. Larger core area and more efficient fin design increase heat transfer, which is helpful if you tow, drive in hilly terrain, or frequently maneuver at low speeds where heat buildup is common.
However, bigger cores can be harder to package and may require more careful mounting to avoid road debris. Evaluate expected driving conditions and choose a core size that balances cooling needs with available mounting space on the Traverse.
Fitment And Mounting Options
Proper fitment ensures the cooler can be secured without stressing hoses or requiring extensive modifications. Look for units with mounting brackets that align with common Traverse mounting points or that offer flexible bracketry for multiple locations, such as in front of the radiator or behind the bumper.
Mounting location affects both cooling performance and protection from debris. Aim for a spot with good airflow but limited exposure to rocks and road salt. Ensure the bracketry allows a slight amount of vibration isolation to prevent fatigue on fittings.
Hose And Fitting Compatibility
Compatibility with existing steering lines is critical to avoid leaks and maintain system pressure. Many coolers use standard hose sizes and common fittings, but some require adapters or hose-end crimping. Confirm the cooler accepts the hose diameter used on the Traverse and whether adapters are included or needed.
Quality fittings and clamps reduce the chance of leaks under pressure and thermal cycling. Reinforced hoses and properly rated fittings help preserve system integrity over time.
Material Quality And Corrosion Resistance
Materials affect longevity and performance in different climates. Aluminum cores are common for good heat transfer and light weight, but their longevity depends on coating and weld quality. Stainless or plated fittings and corrosion-resistant brackets extend service life, especially in areas that use road salt.
Inspect whether components have protective finishes or sacrificial coatings. Durable construction pays off by reducing the likelihood of leaks, reduced heat transfer from corrosion, or early failure of mounting hardware.
Impact On Steering System Pressure And Flow
Any added inline cooler will change flow characteristics and can introduce a small pressure drop. A well-designed cooler minimizes restriction so the steering pump does not work harder than necessary, which preserves steering feel and avoids premature pump wear.
Look for coolers engineered for low pressure loss and for installation guidance that preserves recommended hose routing. If a kit includes a bypass or low-restriction routing option, that can help maintain original system performance while still providing cooling benefits.
Ease Of Installation And Maintenance
Ease of installation affects both total cost and the likelihood you will perform routine checks. Kits that include brackets, fittings, and clear instructions reduce installation time and lower the risk of improper routing. Quick-disconnect fittings or reusable clamps simplify future service.
Consider whether you need specialized tools or hose-pressing equipment. Choose a solution that matches your comfort level for DIY work or that minimizes shop labor time if you plan to have a professional install the cooler.
FAQ
Do I need a power steering cooler for my Chevrolet Traverse?
You may benefit from a cooler if you do frequent low-speed maneuvering, towing, or heavy-duty driving that causes the steering fluid to run hot. A cooler can reduce fluid breakdown and extend component life, but it is not always necessary for light, everyday driving.
Where is the best place to mount a power steering cooler on a Traverse?
Mounting the cooler where it receives steady airflow, such as in front of or just behind the grille area, maximizes cooling. It is important to avoid locations that are highly exposed to road debris and to secure the unit so hoses have gentle bends and no tension.
Will adding a cooler affect steering feel or pump performance?
A properly engineered cooler typically has minimal impact on steering feel because it is designed for low pressure loss. If a cooler is overly restrictive or poorly installed, it can alter flow and increase pump load, so using correct hose sizes and fittings is essential.
Can I install a power steering cooler myself?
Many coolers are designed for straightforward installation with basic hand tools and included brackets. Installation usually involves routing hoses, securing the bracket, and checking for leaks. More complex kits or tight mounting locations may require professional help.
How do I maintain a power steering cooler?
Maintenance is generally simple: periodically inspect for leaks, check hose and clamp security, and ensure the cooler fins are free of debris. If corrosion or damage is visible, replace affected components to prevent fluid contamination.

The final list emphasizes balanced solutions that address overheating, reduce fluid breakdown, and avoid unnecessary complexity during installation.
Our full evaluation process is outlined in our review methodology.
Conclusion
Choosing the right Chevrolet Traverse power steering cooler comes down to balancing cooling performance, fitment practicality, and long-term durability. Prioritize units that provide adequate core area for your typical driving conditions, use corrosion-resistant materials, and offer fittings that match the Traverse steering lines. Also consider installation complexity and the cooler's effect on flow and system pressure. A well-chosen cooler will lower operating temperature without introducing excessive restriction or installation headaches, helping preserve steering components and reliability over time.
