Where is the thermostat located in the Mitsubishi Pajero?

The thermostat in the Mitsubishi Pajero is located in the engine's water inlet. A thermostat is an automatic temperature-regulating device, usually containing a temperature-sensing component. Its function is to automatically adjust the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling capacity of the radiator and ensure the engine operates within an appropriate temperature range. Below is relevant information about the car thermostat: 1. Coolant temperature exceeds 110 degrees. Park the car, turn off the engine, and open the engine hood. Touch the upper hose of the coolant radiator; it should be very hot. Then touch the lower hose of the radiator; it should also be very hot. If there is a significant temperature difference between the upper and lower hoses, it confirms a thermostat malfunction. 2. If the engine takes a long time to reach normal operating temperature. Park the car and let the engine temperature drop to match the ambient temperature. Then start the engine and drive. When the dashboard temperature reaches around 70 degrees, park the car, turn off the engine, and open the engine hood. Touch the upper and lower hoses of the radiator. If there is no temperature difference, it confirms a thermostat malfunction. 3. Use an infrared thermometer to test the thermostat. Aim the infrared thermometer at the thermostat housing. When the engine starts, the temperature of the water inlet will increase, and the thermostat will close. When the water temperature gauge reaches 70 degrees, test the temperature of the water outlet. It should suddenly increase. If there is no change in temperature, it indicates poor thermostat performance, and replacement is needed.
I've repaired many Mitsubishi Pajeros, and the thermostat is usually located in the thermostat housing on the right side of the engine, near the upper radiator hose and water pump. After opening the hood, you can spot it from the front view, with hoses and radiator connections nearby. The thermostat regulates coolant flow to maintain optimal engine temperature. If it gets stuck or leaks, the vehicle may overheat or even suffer engine damage. It's advisable to routinely check coolant levels and visit a professional shop if the temperature gauge fluctuates abnormally. For DIY replacement, exercise caution—draining coolant and removing the housing requires unscrewing several bolts. While the thermostat location is similar between older and newer Pajero models, always consult the manual to account for slight engine layout variations.
