34 in Core Radiator Compatible with Chevy Silverado Tahoe - Direct Fit

In this review the DWVO 34 in core radiator is assessed as a direct OEM fit replacement for a range of GM trucks and SUVs. It is best for owners seeking a like-for-like radiator that replaces OEM part number 22840117 and related replacement numbers, and who prioritize cooling efficiency and a straightforward installation. The single biggest reason to consider it is the complete aluminum core design with high density multi-louvered fins that promise improved heat dissipation compared with many aftermarket cores.

Key Features

• Direct OEM fit: Built to match the 34 in core dimension and OEM part number 22840117 so it installs where the factory radiator did without major modification.
• High density fins: Multi-louvered fins increase surface area for more efficient engine cooling under load or in hot towing conditions.
• Durable construction: Aluminum core with TIG-welded ends and PA66 GF30 inlet/outlet tanks is intended to resist routine vibration and thermal cycling.
• Includes transmission cooler: Integrated aluminum transmission oil cooler preserves transmission temperatures for vehicles with compatible transmissions.
• Enhanced packaging: Fixed foam in four corners protects the radiator during shipping so it arrives without bent fins or damage.
• What you get: The package contains one complete radiator and a user manual; note the radiator cap is not included.

Who It's For

The DWVO 34 in radiator is aimed at DIY mechanics and professional installers replacing a failed or worn radiator on Chevy Silverado, Suburban, Tahoe, Avalanche, Escalade and compatible GMC and Hummer models with 4.3L through 6.2L engines that use the listed OEM number. It is particularly suited for owners who want an affordable full-core replacement with an integrated transmission cooler and a focus on cooling performance.

It may not be ideal for shoppers who require an included radiator cap or who are unwilling to accept some reported concerns about long-term durability and transmission line sealing; those users should consider a factory remanufactured unit or seek a radiator with an extended warranty from the supplier.

Pros & Cons

Cons

• Several users reported issues with leakage and cracking in service, so long-term durability is a potential concern.
• Does not include a radiator cap, which must be purchased separately if needed.
