TRQ Radiator Assembly Aluminum Core Compatible with Mini Cooper S

In this review of the TRQ radiator assembly, the bottom line is clear: this is a practical OE-style replacement for owners of 2002-2006 Mini Cooper S and 2007-2008 Mini Cooper S Convertible models who need a straightforward, direct-fit radiator. The reviewer found the unit offers an aluminum core and plastic tanks with dimensions and outlet/inlet locations that match factory layouts, making installation quick for DIYers or independent shops. Fit and immediate functionality are the strongest reasons to consider it, while buyers mindful of long-term durability should weigh mixed user reports.

Key Features

• Direct Fit: Designed as an OE replacement so mounting points and hose connections align with the original radiator for easier installation.
• Aluminum Core: The aluminum core provides good heat transfer and a lightweight construction compared with all-plastic cores.
• Vehicle Specific: Compatible with specified 2002-06 Mini Cooper S and 2007-08 Cooper S Convertible supercharged engines when fitment checks out.
• Core Dimensions: The 15.88 in height by 22.63 in width core with 1 in thickness closely matches OE sizing for expected cooling capacity.
• Cross Flow Design: A cross flow layout with top right inlet and bottom left outlet keeps coolant routing consistent with the original system.
• Aftermarket Reference Numbers: Supplied references such as 17117570489 and CU2859 help verify compatibility with service documentation.

Who It's For

This radiator is suited for Mini Cooper S owners who need a like-for-like replacement and prefer a part that fits without modification. It works well for garage mechanics and DIY enthusiasts who want a unit with factory-style core thickness and mounting locations to minimize installation time.

It is less suitable for owners seeking upgraded cooling capacity beyond OE specifications or those who require built-in engine or transmission oil coolers, since this assembly has no internal oil cooler and is intended as a standard replacement part.
