A-Premium 34ft Engine Coolant Radiator Assembly Compatible

In this review the A-Premium 34' engine coolant radiator assembly is evaluated as a direct replacement option for a wide range of GM trucks and SUVs. It is aimed at owners who need a full radiator replacement that includes both the engine and transmission oil cooler, and the single biggest reason to consider it is the larger 34' core width and 32 mm core thickness which are designed to deliver improved cooling compared with narrower aftermarket cores. For vehicles that match the listed fitment, it presents a straightforward, value-focused swap for a failing original unit.

Key Features

• Comprehensive fitment: Covers many GM models including Silverado, Sierra, Tahoe, Suburban, Yukon and Cadillac Escalade across multiple years, so buyers can often replace the radiator without modification.
• Includes transmission cooler: Comes with an integrated transmission and engine oil cooler, eliminating the need to purchase separate components for automatic transmission models.
• 34' core width: The larger core width offers increased surface area which helps dissipate heat more effectively than smaller 28' cores.
• 32 mm core thickness: Thicker core construction improves cooling performance relative to thinner 26 mm alternatives for heavy-duty use.
• Direct replacement references: Matches common reference numbers such as 13029 and CU2370 to help cross-check compatibility with factory units.

Who It's For

This radiator is best for owners of compatible Chevrolet, GMC, Cadillac or Hummer H2 models who need a full radiator assembly with an integrated transmission oil cooler and prefer a larger core for better cooling performance. It is practical for those performing a like-for-like replacement or upgrading from a smaller aftermarket core.

It is not the best choice for vehicles outside the listed fitment or for buyers who require OEM-branded parts with verified long-term durability. Customers concerned about build quality variability or long-term leak resistance should consider professional installation and inspection before purchase.

Pros & Cons
