The Motorad 5158KT is a complete engine coolant thermostat housing assembly built for 1996-2000 Honda Civic 1.6L engines, covering D16Y5, D16Y7, D16Y8, and B16A2 applications. This kit takes the guesswork out of a cooling system repair by combining the housing, thermostat, and O-ring seal in one package, so you're not chasing down separate parts or worrying about a mismatched gasket. Constructed with copper, stainless steel, and rubber components, the assembly is designed to hold up under the heat and pressure cycles of daily driving. The thermostat itself opens at 170°F, giving your engine the consistent temperature regulation it needs to run efficiently and avoid overheating. With a disk-style valve and mechanical actuator, this is a straightforward, no-frills replacement designed to restore proper coolant flow. Because the seal is already included, installation is simpler and there's less chance of a leak from an incorrect or missing gasket.
