A-Premium Power Steering Cooler for Chevrolet GMC Cadillac — Direct-Fit OEM Replacement, Aluminum Core (2002–2013)

A-Premium Power Steering Cooler is a direct-fit OEM-style replacement that lowers fluid temperature to protect your steering system and restore smooth performance.

This aluminum-and-steel power steering fluid cooler is engineered to match original equipment dimensions for a straight swap into a range of Chevrolet, GMC and Cadillac trucks and SUVs from model years spanning the late 1990s through 2013. Built with a high-efficiency heat sink and precision inlet/outlet fittings, it reduces heat-related steering problems while preserving fluid viscosity and easing load on pumps and hoses.

Will this cooler fit my vehicle?

If your vehicle is one of the listed Chevrolet, GMC or Cadillac models and years, this cooler was manufactured to the same mounting and connection specifications as the original part. Confirm fitment by checking the provided reference numbers or matching the cooler’s overall dimensions and fitting diameters to your existing unit.

• Reference part numbers: 918-301, 918301, 15295843, 25895896 for cross-checking.
• Physical specs: Height 2.007 in, Length 17.078 in, Width 12.047 in; inlet/outlet fittings 0.275 in ID / 0.374 in OD.

How does this cooler improve steering performance?

By shedding excess heat from the power steering fluid, the cooler helps the hydraulic system maintain proper fluid viscosity and reduces the risk of pump strain or premature wear. That stabilization leads to more consistent steering feel, especially under towing, hauling or stop-and-go conditions that raise under-hood temperatures.

• Aluminum heat sink design increases thermal transfer and dissipation.
• Reduces incidents of steering noise, sticking or chatter caused by overheated fluid.
• Helps extend life of hoses, seals and the power steering pump.

What are the construction and warranty details?

The cooler combines durable steel mounting components with an aluminum core to balance strength and thermal efficiency. It is manufactured to match OEM form, fit and function and ships with a limited one-year warranty that covers manufacturing defects under normal installation and use.

• Materials: steel bracketry and high-efficiency aluminum core.
• OEM-style inlet/outlet fittings for a straightforward replacement.
• One-year limited guarantee from date of installation or purchase.

How do I install it and what should I check afterwards?

Installation is intended as a professional replacement—mounting points and fittings are made to align with factory locations for a direct swap. After installation, inspect for leaks, confirm secure hose clamps, and test steering response at idle and low speeds to ensure correct fluid flow and cooling.

• Drain fluid according to manufacturer guidance before removing the old cooler.
• Replace or tighten hose clamps and verify inlet/outlet orientation matches hoses.
• Refill with recommended power steering fluid and bleed the system to remove air pockets.

Who is this for: technicians, DIY mechanics and owners of compatible Chevrolet, GMC and Cadillac trucks and SUVs who need a reliable, OEM-spec replacement cooler to restore proper steering performance. It's especially useful for vehicles subjected to heavy loads or high-temperature conditions where steering fluid can overheat and affect system reliability.
