Detailed Description

Motorad 1263-189 is an engine coolant control valve manufactured with OEM-quality materials and processes. The design uses a plastic housing, electrical actuator, disk valve type, and pin terminals, with multiple outlet port and mounting configurations represented in the product data. This part is intended for cooling systems that require precise coolant routing and temperature response. It is a relevant replacement for Chevrolet Silverado 1500 and GMC Sierra 1500 cooling system service, as well as Chevrolet Colorado, GMC Canyon, and Cadillac CT4 applications where this control valve configuration is specified.
