  2. INSTALL UPPER RADIATOR TANK AND LOWER RADIATOR TANK 
    1. Check that there are no foreign objects in the lock plate groove, and install a new O-ring. Make sure that the O-ring is not twisted.

      HINT:

      When cleaning the lock plate groove, lightly rub it with sandpaper without scratching it.

  5. INSTALL RADIATOR DRAIN COCK PLUG 
    1. Install a new O-ring to the drain cock plug.
    2. Install the drain cock plug.
  6. INSPECT FOR WATER LEAKS 
    1. Plug the inlet and outlet pipes of the radiator with SST.

      SST 09230-01010 

    2. Using a radiator cap tester, apply pressure to the radiator.

      Standard test pressure: 

      177 kPa (1.8 kgf/cm 2  , 26 psi) 

    3. Submerge the radiator in water.

    4. Inspect for leaks.

      HINT:

      On radiators with resin tanks, there is clearance between the tank and lock plate where a small amount of air will remain. This air is released when the radiator is submerged in water, giving the appearance of an air leak. Before performing the water leak test, first swish the radiator around in the water until all air bubbles disappear.
