TRQ Radiator Assembly Aluminum Core Compatible with 03-06 Acura MDX

In this review the TRQ Radiator Assembly is evaluated for owners of 2003-06 Acura MDX and 2005 Honda Pilot who need a direct-fit OE replacement. The bottom line: this radiator is best for DIY mechanics and repair shops that want an affordable, vehicle-specific replacement that aligns with OE reference numbers and fits without major modification. Our review finds the unit delivers correct mounting locations, matching core dimensions, and an integrated transmission oil cooler, making it a practical swap for those prioritizing fit and serviceability.

Key Features

• Direct Fit: Designed to match the original mounting points so installers can replace the radiator without fabricating brackets or hoses.
• OE Replacement: Built to the same general form as the OEM unit with equivalent core thickness for consistent cooling performance.
• Vehicle Specific: Selected compatibility for 2003-06 Acura MDX and 2005 Honda Pilot helps reduce fitment guesswork when checking the listing.
• Integrated Transmission Oil Cooler: Includes an internal transmission oil cooler with concentric type fittings to maintain automatic transmission cooling.
• Aluminum Core: The aluminum core and plastic tanks provide a balance of weight savings and corrosion resistance compared with older all-brass designs.
• Core Dimensions: The specified 1 in core thickness and 19.75 in by 30.25 in core size make it straightforward to confirm fit against the removed unit.

Who It's For

This radiator is aimed at Acura MDX and Honda Pilot owners who need a like-for-like replacement without the higher price of an OEM dealership part. It suits experienced DIYers and independent shops that value parts which line up and save installation time. The inclusion of the transmission oil cooler makes it appropriate for vehicles originally equipped with that feature.

Those who should look elsewhere include owners seeking an OEM-branded part with manufacturer warranty coverage or users who require a radiator with an included cap or additional accessories; this part ships without a radiator cap and some buyers may prefer a complete kit from the dealer.
