A Pajero radiator is the brand of radiator used in Mitsubishi vehicles. The radiator keeps the engine cool and prevents overheating. Over time, the fluid inside the radiator can cause gunky build-up inside the radiator, which can hamper the performance of the unit. Cleaning a Pajero radiator is not a difficult process, and you can use the same cleaning process that you can for any other radiator. The cleaning process will take between one and two days to complete. Make sure the engine is cold before attempting any cleaning.

Instructions

  1. 1

    Allow the car to cool for 12 hours before attempting to clean the radiator. Unscrew the drain cap at the bottom of the radiator and allow the radiator fluid to drain into the drain pan.

  2. 2

    Close the plug and fill the radiator with water. Turn on the car and run the engine until the water circulates completely through the engine. You should be able to see steam. Allow the engine to cool for one or two hours. Repeat the draining and water filling process one more time. Drain the water from the radiator and allow the engine to cool.

  3. 3

    Fill the radiator with a radiator system flush. Turn on the heater and run the engine for about 10 minutes. Follow the instructions on the flush bottle if they differ. Some flushes have a slightly different procedure.

  4. 4

    Drain the radiator, then fill with water. Run the water through the engine, then drain it. Repeat the flush process one more time.

  5. 5

    Fill the radiator with antifreeze. Fill the radiator with 50 per cent antifreeze and 50 per cent water. Run the engine and heater one last time for about 10 minutes to flush the antifreeze through the system.

Tips and warnings

  • Never touch a hot radiator, or put your face or other skin close to the radiator while it is heated. The steam from the radiator can cause serious injuries and burns.
