YITAMOTOR Radiator Compatible with 99-13 GMC Sierra 1500 Classic

Our review of the YITAMOTOR OE style radiator finds it best for owners of late 1990s to early 2010s full-size GM trucks and SUVs who need a direct-fit replacement that restores cooling performance without expensive OEM pricing. The biggest reason to buy is straightforward: it replaces worn or damaged cores with a high-density aluminum construction and an integrated aluminum oil cooler that improves heat dissipation, so engines run cooler and resist overheating during towing or heavy use.

Key Features

• Compatibility: Designed to fit 1999-2013 GMC Sierra 1500 Classic, Yukon XL 1500, Cadillac Escalade EXT/ESV, Hummer H2, Chevrolet Avalanche, Silverado 1500 Classic, Tahoe and Suburban models, making it a direct replacement for many OE radiators.
• Core and header size: A large 34in x 17in core with 18.3in x 3.0in headers provides a substantial radiation area for improved cooling under load.
• High cooling efficiency: The high-density aluminum tubes and fins plus the aluminum oil cooler increase cooling capacity and help the engine maintain safe operating temperatures.
• Leakproof construction: Seamless welding and glass fiber reinforced nylon PA66 tanks reduce the risk of cracks and coolant leaks over time.
• Packaged for protection: Each unit is 100% leak-tested and shipped with EPE foam and multi-layered cardboard to minimize transit damage.
• Support and warranty: YITAMOTOR offers a 1-year warranty and lifetime customer service for replacement guidance and support.

Who It's For

This radiator is aimed at DIY mechanics, independent repair shops and owners of compatible GM trucks and SUVs who want an OE-style replacement that matches factory mounting points and hose locations. It is particularly useful for vehicles used in towing, hauling or frequent highway driving where improved engine cooling matters.

Customers who need a dealership-only part with factory packaging or who require a radiator cap included should look elsewhere, since the radiator is sold without the cap and is positioned as an aftermarket OE-style replacement rather than an OEM boxed assembly.
