The OSC Radiator (part number 618) is a direct-fit replacement for 1988-1997 Chevrolet and GMC vehicles with 5.7L, 5.0L, and 4.3L engines.

Features:

• Hassle free installation
• O.E. performance and exceptional quality
• Engineering enhancements provide improved cooling and longer life cycle
• Components are fitted and torqued in place to factory specifications
• Drop in fit, form and function. All necessary fittings or hardware are included in each unit for an easy install.
• Complete Radiators 100% tested up to three times during production: OSC tests the transmission and engine oil coolers prior to installation into the tank. The radiator core is tested prior to assembly and then once the assembly is complete the unit is tested again.
• Enhancements added to solve original design failures and to improve the life of high mileage vehicles: adding more fins per inch, thicker cores and even larger transmission coolers to overcome the added heat associated with these vehicles.
