Detailed Product Description

The Gates Integrated Housing Thermostat 34723 is a non-electric engine coolant thermostat designed specifically for Land Rover Discovery models. Featuring an integrated housing, this thermostat simplifies replacement by combining the thermostat and housing into a single unit. It opens at a precise temperature of 180°F (82°C), allowing coolant to flow through the engine only when optimal operating temperature is reached. The thermostat includes a jiggle pin weep hole, which helps to release trapped air and prevent coolant system air locks, enhancing overall cooling efficiency.

With outlet inside diameters of 1.045 and 1.13 inches and outside diameters of 1.3 and 1.365 inches, this part ensures a secure and proper fit with the vehicle’s cooling hoses. The absence of bolt holes indicates a specific mounting design compatible with Land Rover Discovery cooling systems. This thermostat does not include an electric component or check valve, aligning with the original equipment specifications for this application.
