ACDelco 21738 GM Original Equipment Aluminum Radiator with Crossflow Design

The ACDelco 21738 GM Original Equipment Radiator is a factory-quality replacement radiator designed specifically for GM vehicles. This genuine OE part delivers the same performance, durability, and service life as the original component installed at the factory.

Key Features:

• Aluminum and plastic construction provides lightweight design with excellent heat transfer characteristics
• Crossflow design optimizes cooling efficiency for consistent engine temperature management
• Integrated transmission cooler included for automatic transmission applications
• Corrosion-resistant aluminum core ensures long-lasting service life and reliability
• Direct-fit replacement manufactured to exact GM OE specifications for proper fitment
• Positive heat transfer to weight ratio maximizes cooling while minimizing added weight

This radiator is designed, engineered, and tested to rigorous GM standards and is backed by General Motors. The aluminum core with plastic tanks represents modern radiator technology, offering superior strength and corrosion resistance compared to older copper-brass designs. As a heat exchanger positioned at the front of the vehicle, this radiator allows air to flow through its fins to effectively dissipate engine heat and maintain optimal operating temperatures.
