It is designed for engines using a single and 3-point drain system. The kit supplies everything needed to restore correct engine operating temperature in one purchase, rather than sourcing the thermostat and gaskets separately.\u003c\/p\u003e\u003cp\u003eInside the kit is an 18-3649 thermostat rated to open at 160 degrees Fahrenheit, along with an 18-2553 thermostat cover gasket and an 18-2917 thermostat gasket, so the sealing surfaces are replaced along with the thermostat itself for a proper seal on installation.
