Radiator Coolant Reservoir Expansion Tank Compatible with 2011-14

In this review of the TRQ radiator coolant reservoir expansion tank, the bottom line is clear: this is a practical direct-fit replacement for owners of 2011-2014 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD with the 6.6L V8 who need a straightforward, functional coolant recovery solution. The reviewer found the tank delivers the single biggest benefit buyers want - reliable fitment and compatibility - and notes the preassembled, pressure-cap included design cuts installation time and avoids modifications.

Key Features

• Direct-fit compatibility: The tank is built to replace the original and lists reference numbers GM3014184 and 22866587 for easy match with factory parts.
• Preassembled design: Preinstalled components mean most owners can swap the reservoir without cutting or modifying hoses or mounts, saving time in the garage.
• Pressurized cap included: A pressure-rated cap is supplied and rated to 20 PSI so the cooling system maintains proper pressure under load.
• Sensor ready: The unit ships with a level sensor installed, preserving the truck's warning and monitoring functions without rewiring.
• Durable construction: Molded plastic construction provides corrosion resistance and durability consistent with replacement coolant reservoirs.

Who It's For

This reservoir is aimed at owners or mechanics who maintain heavy-duty Chevrolet and GMC trucks from the 2011-2014 model years with the 6.6L V8 and need a cost-effective replacement that matches factory fitment. It is a good option for fleet service shops and DIY owners who want a quick repair without chasing multiple components.

It is less suitable for vehicles outside the listed fitment or for users who require OEM-branded packaging or included mounting hardware, since mounting bolts are not provided. Buyers who need custom or modified cooling solutions should look elsewhere.
