• Q: How to reassemble the radiator on 2008 Toyota Avalon?

  A: The radiator reassembly requires cleaning the O-ring contact area of lower tank and oil cooler before installing two new O-rings to secure the oil cooler to the lower tank with plate washer and nut tightened to 8.3 Nm (85 kgf-cm, 73 in-lbf). Mount the cooler pipe with 15 Nm (150 kgf-cm, 11 ft-lbf) torque before fastening it with a screw. Before installing the new O-ring in the lock plate groove users must ensure no foreign objects are present and they must avoid twisting the O-ring to prevent damage then they should install the tank with care by tapping the lock plate gently with a soft-faced hammer to keep the gaps closed. Secure Special Service Tools: 09230-01010 and 09231-14010 on the punch assembly of the overhaul handle to adjust stopper bolt setting for dimension B at 8.4 mm (0.331 in.). The operator uses Special Service Tool: 09230-01010 to press against the lock plate in the specified manner to prevent striking any vulnerable areas including pipes brackets and tank ribs. The user should check the height measurement (H) of the lock plate to fall between 7.40 to 7.80 mm (0.2913 to 0.3071 in.) making any required adjustments. Next install a new O-ring to the drain plug before attaching the drain plug to its position. Before closing the service, inspectors should densely plug the inlet and outlet pipes with Special Service Tool: 09230-01010, conduct a 177 kPa (1.8 kgf/cm2, 26 psi) test with a radiator cap tester, submerge the radiator in water, and inspect for leaks noting that trapped air in resin tanks produces leak-like visual effects.
