Built to original equipment form, fit and function, the Tridon Coolant Expansion Tank covers Mitsubishi Outlander 2.0L PHEV AWD models built from 2017 to 2019. Pressure rating is 100kPa; running the wrong rating will either boil the coolant or stress the radiator seams. Opening temperature is 80 degrees Celsius, matching the engine management calibration. The Plastic construction resists coolant additives, heat cycling and pressure fatigue. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Fitting is a straightforward workshop job and no coding or calibration is needed. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Packaging and labelling include the part number and application data for easy stock control. Every unit is supplied new with a 36 Months warranty against manufacturing defect.
