Where is the thermostat located in the Nissan Sylphy?
1 Answers
The thermostat of the Sylphy is installed at the connection between the lower hose and the engine block. The thermostat is a valve used to control the flow path of the coolant, serving as an automatic temperature-regulating device. It typically contains a temperature-sensing component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction. The steps for replacing the thermostat are as follows: 1. Turn off the engine, open the front hood, and disconnect the negative terminal of the battery. This is to prevent the electric fan from suddenly operating during the work, which could cause personal injury. 2. Remove the plastic cover outside the timing belt. 3. The position of the generator may affect the replacement of the thermostat, so the generator assembly needs to be removed. 4. Place a water-catching tray under the vehicle, then prepare to remove the hose and wait for the antifreeze to drain completely. 5. Remove the faulty thermostat and install the new one. After installing the thermostat, apply a layer of sealant to the hose connection. 6. Reinstall the removed hose, generator, and timing belt cover to their original positions. Reconnect the negative terminal of the battery, add new antifreeze, and then start the engine for testing.
