Upgrade your 2019-2025 Chevy Silverado or GMC Sierra 1500 with a radiator built to handle the toughest jobs and weekend adventures. Crafted from TIG-welded aluminum with durable aluminum side brackets, our Performance Aluminum Radiator replaces the factory’s brittle plastic components to eliminate cracks and leaks while ensuring a precise, secure fit.--With a 119% increase in core volume and 31% increase in fluid capacity over stock, this radiator delivers exceptional cooling performance to keep your engine running at peak efficiency. A 7-row internal oil cooler improves heat transfer compared to the OEM’s 6-row design, while strutted tubes along the top and bottom rows add strength and rigidity to withstand vibration, pressure, and chassis flex. Foam applied to the back of the core ensures a proper fan shroud seal, maximizing airflow for consistent cooling no matter the conditions.--For added protection, the radiator includes a magnetic drain plug that captures debris and metal fragments circulating through the cooling system. Whether you’re hauling heavy loads, towing uphill, or exploring the backcountry, our Performance Aluminum Radiator keeps your truck cool, reliable, and ready for anything. Like every Mishimoto product, it’s backed by our Lifetime Warranty for complete confidence on every drive.
