    1. Install the rear door scuff plate LH with the 3 screws.

  3. ADD ENGINE COOLANT


    1. Slowly fill the system with coolant.


      • Use of improper coolants may damage engine cooling system.


      • Use "Toyota Long Life Coolant" or equivalent and mix it with plan water according to the manufacturer's directions.


      • Using of coolant which includes more than 50 % [freezing protection down to -35°C (-31°F)] or 60 % [freezing protection down to -50°C (-58°F)] of ethylene-glycol is recommended but not more than 70 %.

      Note


      • Do not use an alcohol type coolant or plain water alone.


      • The coolant should be mixed with plain water (preferably demineralized water or distilled water).

    *1 Radiator Cap Tester

    1. Fill the radiator with coolant and attach a radiator cap tester.

    2. Warm up the engine.

    3. Pump it to 118 kPa (1.2 kgf/cm2, 17.1 psi), and check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator or water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.
