Detailed Product Description

The Gates Integrated Housing Thermostat 34246 combines the thermostat and housing into a single unit, simplifying installation and improving reliability. This part features an electric thermostat with a start-to-open temperature of 207°F (97°C), ensuring the engine coolant begins circulating at the correct temperature to maintain optimal engine operation. The integrated check valve and jiggle pin help regulate coolant flow and allow trapped air to escape, reducing the risk of overheating and coolant system damage.

With multiple outlet inside and outside diameters, this thermostat housing is designed to fit a range of BMW engines precisely, ensuring a secure connection to the cooling system. The absence of bolt holes indicates a design intended for specific mounting configurations, consistent with OE performance standards, though it is not an exact OE replacement.
