ON−VEHICLE CLEANING

1. INSPECT FINS BLOCKAGE

a. If the fins are clogged, wash them with water or a steam cleaner. Dry with compressed air.

NOTICE:

  • If the distance between the steam cleaner and the core is too close, the fins may become damaged.

    Keep the following injection distance.

    Standard:

  • If the fins are bent, straighten them with a screwdriver or pliers.

  • Never apply water directly onto the electronic components.

7. INSPECT LOCK PLATE FOR DAMAGE

Inspect the lock plate for damage.

HINT:

  • If the sides of the lock plate groove are deformed, reassembly of the tank will be impossible.

    Therefore, correct any deformation with pliers or similar object first.

  • Water leakage will result if the bottom of the lock plate groove is damaged or dented. Repair or replace if necessary.

NOTICE: The radiator can only be recaulked 2 times. After the 2nd time, the radiator core must be replaced.


Inspect lock plate for damage

8. INSTALL RADIATOR TANK UPPER AND TANK LOWER

a. After checking that there are no foreign objects in the lock plate groove, install a new O−ring without twisting it.

HINT: When cleaning the lock plate groove, lightly rub it with sand paper without scratching it.

  1. Install the tank without damaging the O−ring.

  2. Tap the lock plate with a soft−faced hammer so that there is no gap between the lock plate and the tank.

9. ASSEMBLE SST

9. ASSEMBLE SST

SST 09230−01010, 09231−14010

  1.  Install the punch assembly to the overhaul handle, inserting it in the hole in part A as shown in the illustration.

  2.  While gripping the handle, adjust the stopper bolt so that dimension B shown in the illustration.

    Dimension B: 8.4 mm (0.331 in.)


Assemble SST

10. CAULK LOCK PLATE

a. Lightly press SST against the lock plate in the order shown in the illustration. After repeating this a few times, fully caulk the lock plate by gripping the handle until stopped by the stopper plate.

SST 09230−01010

HINT:

HINT:

  • Do not tap the areas protruding around the pipes, brackets or tank ribs.

  • The points shown in the illustration and oil cooler near here cannot be tapped with the SST. Use pliers or similar objects and be careful not to damage the core plates.

b. Check the lock plate height h. after completing the

b. Check the lock plate height h. after completing the caulking.

Plate height h.: 7.40 to 7.80 mm (0.2913 to 0.3071 in.)

If not within the specified height, adjust the stopper bolt of the handle again and caulk again.

11. INSTALL DRAIN PLUG

11. INSTALL DRAIN PLUG

  1. Install a new O−ring to the drain plug.

  2.  Install the drain plug.

12. 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.

    Test pressure: 177 kPa (1.8 kgf/cm2, 26 psi)

  3. Submerge the radiator in water.

d. Inspect for leaks.

d. Inspect for leaks.

HINT: On radiators with resin tanks, there is a clearance between the tank and lock plate where a minute amount of air will remain, giving the appearance of an air leak when the radiator is submerged in water. Therefore, before doing the water leak test, swish the radiator around in the water first until all air bubbles disappear.
