The Sierra 18-3652 is a thermostat kit for Mercruiser stern drives with a 160 degree temperature rating. It contains a thermostat, a thermostat gasket and a thermostat cover gasket. The application list names specific older engines, such as the 470 2 BBL I/L4, with serial ranges. Check your engine's serial number against that list before fitting the kit.
Our take
The 160 degree rating comes with a thermostat, a thermostat gasket and a cover gasket in the same kit, so the seals for the swap are included. The application list is tied to serial ranges, so check your engine's number first.
