Koyo A13767 Koyorad OE Replacement Radiator – Plastic Tank / Aluminum Core

The Koyo A13767 is a premium OE replacement radiator engineered for 2019–2020 Chevrolet Silverado 1500 and GMC Sierra 1500 models equipped with 5.3L or 6.2L V8 engines without the heavy-duty tow package. Manufactured to meet or exceed original equipment standards, this Koyorad radiator delivers reliable, long-lasting cooling performance right out of the box.

Key Features:

• Plastic tank / aluminum core construction — combines lightweight durability with efficient heat dissipation
• Nocolok furnace-brazed core — tubes, fins, and headers are bonded using a state-of-the-art brazing process for resistance to vibration, road debris, and corrosion
• OE-specific mounting locations — application-engineered brackets, hose ports, and mounting pins ensure a true plug-and-play installation with no drilling, cutting, or modifications required
• ISO 9001 certified manufacturing — produced in Koyo's privately owned facilities under strict quality control procedures
• Meets or exceeds OEM specifications — engineered to restore factory cooling capacity and fitment precision
• Designed to retain factory fan shroud and all OE connections

Koyorad has been a trusted name in radiator manufacturing for over 50 years, backed by Japan's renowned engineering expertise. The A13767 is the correct direct-fit replacement for non-tow-package applications — vehicles equipped with the factory tow package require a different radiator with an integrated transmission cooler. This radiator ships safely in Koyo's class-leading protective packaging and is ready for professional or DIY installation.
