Nissan Rogue Service Manual: Thermostat and water control valve
Exploded View
- Water inlet
- Thermostat
- Rubber ring
- To radiator hose (lower)
NOTE: When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
Removal and Installation
WARNING: Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.
REMOVAL
- Drain engine coolant from the radiator. Refer to CO-8, "Draining".
CAUTION:
- Perform this step when the engine is cold.
- Do not spill coolant on drive belt.
- Remove engine under cover. Refer to EXT-37, "ENGINE UNDER COVER : Removal and Installation".
- Remove radiator hose (lower) from the water inlet side.
- Remove exhaust manifold heat shield. Refer to EM-29, "Exploded View".
- Remove water inlet and thermostat.
INSTALLATION
Installation is in the reverse order of removal.
- Install the thermostat with the whole circumference of the flange fitting securely inside the rubber ring.
CAUTION:
- Do not reuse rubber ring.
- Ensure thermostat rubber ring mounting surface is free from dents or flaws.
- Install the thermostat with the jiggle valve facing upwards. The position deviation may be within the range of ±20°.
- After installation, refill coolant and check for leaks. Refer to CO-9, "Refilling" and CO-8, "Inspection".
Inspection
INSPECTION AFTER REMOVAL
- Place a thread (A) so that it is caught in the valves of thermostat (1) and water control valve. Immerse fully in a container (B) filled with water. Heat while stirring. (The example in the figure shows thermostat.)
- The valve opening temperature is the temperature at which the valve opens and falls from the thread.
- Continue heating. Check the maximum valve lift amount.
NOTE: The maximum valve lift amount standard temperature for water control valve is the reference value.
- After checking the maximum valve lift amount, lower the water temperature and check the valve closing temperature
Standard Thermostat : Refer to CO-25, "Thermostat".
- If out of the standard, replace either or both thermostat and water control valve.
INSPECTION AFTER INSTALLATION
- Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the radiator cap tester (commercial service tool). Refer to CO-8, "Inspection".
- Start and warm up engine. Check visually that there is no leakage of engine coolant.
