Gates 34245 Integrated Housing Engine Coolant Thermostat

The Gates 34245 is an integrated housing engine coolant thermostat that combines the thermostat and water outlet into a single, all-in-one assembly. This integrated design simplifies installation and ensures proper thermostat orientation as the housing bolts directly to the engine block. The unit opens at 221°F (105°C) and features a reverse poppet design that opens against coolant flow from the water pump, using water pump pressure to help keep the thermostat sealed when cool to reduce leakage.

Key Features:

• Complete bolt-on solution includes thermostat, insert, seal, and housing for a complete replacement job
• Integrated housing design with 3 bolt holes for secure, properly oriented installation
• Opens at 221°F (105°C) for precise temperature regulation and engine efficiency
