Thermostat Water Inlet Assembly
The URO Parts 31355151 is a new engine coolant thermostat and water inlet assembly designed for automotive cooling system repair. It serves mechanics and vehicle owners replacing a failed thermostat housing or inlet component.
Black housing fits cooling circuit
The black assembly integrates the thermostat and water inlet into a single unit that mounts into the existing cooling circuit. It replaces the original housing without requiring separate thermostat installation, freeing up labour time during the repair.
Replaces worn thermostat housing
This part upgrades from a cracked, leaking or stuck thermostat housing that causes overheating or coolant loss. The jump is worth it when the original inlet assembly is damaged or the thermostat no longer regulates temperature correctly.

Questions about this item
What is the first limitation that appears during continuous engine operation?
The thermostat regulates coolant flow; if it fails to open fully the engine will overheat, which is the primary limit under sustained use.
How much noise, heat or extra power does the assembly add once the engine runs all day?
The unit is a passive mechanical valve; it adds no noise, no electrical draw and no additional heat beyond normal coolant temperature.
What existing cooling-system components must already be on the vehicle for this inlet to install correctly?
You need the matching radiator hose, flange gasket and mounting bolts that correspond to the original equipment layout.
