Detailed Product Description and Features

This URO thermostat assembly features a MAP controlled design, allowing it to respond accurately to manifold absolute pressure changes, which helps maintain the engine’s ideal operating temperature. The thermostat opens at 210°F, ensuring coolant flow begins at the correct temperature to prevent engine overheating or inefficient warming. The thermostat itself is constructed from stainless steel, providing corrosion resistance and durability under high-temperature conditions.

The housing is made from PA-66 gf30, a glass-fiber reinforced nylon material that offers excellent strength and thermal stability. The black finish adds to its resistance against heat and wear. This assembly includes a gasket or seal to ensure a tight, leak-free connection when installed. The mounting hole diameter is 6 mm, matching OEM specifications for a secure fit.
