Radiator for Cadillac XT5/XT6 Chevy Blazer GMC Acadia - Direct OEM Fit

In this review of the Readair radiator assembly, the bottom line is simple: this unit is for owners of Cadillac XT5 (2017-2024), XT6 (2020-2024), Chevy Blazer (2019-2024) and GMC Acadia (2017-2023) who need a direct OEM fit replacement that prioritizes durable cooling performance. The reviewer found the radiator's high-density multi-louvered fins and aluminum core deliver consistent cooling, and the TIG-welded construction with PA66 GF30 tanks signals a robust build. Our review highlights fit, ease of installation and a two-year unlimited-mileage guarantee as the main buying reasons.

Key Features

• Direct OEM fit: Designed to match factory mounting points and connections for the listed Cadillac, Chevy and GMC models, reducing modification time during installation.
• High-density fins: Multi-louvered fins increase cooling surface area to help manage engine temperature under load or in hot climates.
• Durable construction: An aluminum core with TIG-welded ends and PA66 GF30 inlet/outlet tanks aims to resist cracking and extend service life in varying weather conditions.
• Integrated transmission cooler: The brass transmission oil cooler is built in to provide necessary cooling for automatic transmission fluid where applicable.
• Leak-tested: Each unit is subjected to leakage checks and uses high-grade plastic tanks to minimize the chance of coolant loss after installation.
• Two-year guarantee: A two-year unlimited-mileage warranty gives added confidence for drivers replacing a failed radiator.

Who It's For

This radiator is best for DIY mechanics and professional technicians replacing a failed or leaking radiator on compatible Cadillac XT5/XT6, Chevy Blazer or GMC Acadia vehicles with 2.5L or 3.6L engines between the listed model years. It is particularly suitable for owners who need an OEM-style replacement that focuses on cooling efficiency and long-term durability.

Those who should look elsewhere include owners of non-listed model years or engine variants, and shoppers who require an upgraded performance radiator with larger capacity or aftermarket tuning features; this unit is an OEM-fit replacement rather than a high-performance racing core.

Pros & Cons

Pros

• Good fit and function: customers report the assembly fits well and restores normal cooling performance.
• Solid build quality: aluminum core, TIG-welded ends and reinforced tanks provide durability.
• Easy installation: many owners note the unit is straightforward to swap in using existing mounts.
• Warranty and support: the two-year unlimited-mileage guarantee and 24/7 service access add value.

Cons

• Occasional shipping damage: one customer mentioned bentness on arrival, so inspect the core and fins before installation.
• Not a performance upgrade: this is an OEM replacement and not designed for increased cooling capacity beyond stock.
