Toyota 1603131011 — Water Inlet Sub-Assembly with Thermostat

Overview

Cooling system hose with thermostat Toyota 1603131011 controls coolant circulation between the engine block and radiator. Supply includes the water outlet hose assembly and pre-installed thermostat. The body is manufactured from heat-resistant glass-reinforced polyamide with cast aluminium connection flanges. Thermostat opening temperature is 82 °C, reaching full valve stroke at 95 °C. Hose internal connection diameters are 34 mm and 38 mm. Reference OEM part number is 16031-31011. The valve regulates coolant flow through the bypass circuit during initial warm-up, directing flow to the main radiator when working temperature rises. Supplied rubber sealing ring withstands system pressures up to 1.3 bar and operating temperatures up to 120 °C.

Fits Toyota Camry V40 3.5, Camry V50 3.5, RAV4 XA30 3.5, Highlander XU40 3.5, Highlander XU50 3.5, and Lexus RX350 GGL15 models built between 2006 and 2018 fitted with 2GR-FE 3.5L V6 petrol engines. Replacement becomes necessary when plastic housing hair-line cracks appear, connection spigots erode, rubber seals degrade, or the internal thermostat valve sticks open or closed. A failed housing assembly causes delayed engine warm-up, heater temperature drop, or coolant loss leading to engine overheating under load. Direct replacement item corresponding to original factory specifications.
