Description

Mishimoto 1968 Chevrolet Chevelle Manual X-LINE (Thicker Core) Aluminum Radiator

An ideal upgrade for the brittle stock radiator, the Mishimoto 1968-72 Chevrolet Chevelle X-Line Performance Aluminum Radiator provides your car with enhanced reliability and improved cooling efficiency. Whether you use your classic for daily driving or take it to the track, many people overlook the importance of installing an upgraded radiator in their engine. A stock radiator cannot handle the heat that comes along with having a great deal of horsepower. The Mishimoto Chevrolet Chevelle X-Line Aluminum Radiator is manufactured using durable aircraft-quality aluminum end tanks, precision TIG-welded to an efficient brazed aluminum core. The inlet and outlets provide precise leak-free connections. This performance radiator also includes a Magnetic Oil Drain Plug, which effectively removes metal fragments circulating in the cooling system. As with all our products, this radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.

Additional Information

Aluminum radiator engineered for efficient heat dissipation and optimal engine cooling. Precision-fit design ensures easy installation, corrosion resistance, and reliable performance across varied driving conditions.
