• Q: How to service and repair a radiator on 2005 Toyota RAV4?

  A: Service and repair efforts on the radiator should start with drain plug removal along with its O-ring. Assemble Special Service Tool: 09230-01010 by affixing its claw to the overhaul handle and readjusting the stopper bolt until it measures 0.2 to 0.3 mm (0.008 to 0.012 inch). You should use the tool to remove lock plate caulking while pulling the handle until the stopper bolt stops moving. A soft-faced hammer allows the removal of tanks and O-rings after lightly tapping the radiator bracket while the two oil cooler pipes can be detached from the lower tank by loosening nuts then removing O-rings. The reassembly process starts with installing two new O-rings to the oil cooler followed by torquing the nuts to 12 Nm while installing the LH and RH cooler pipes that require torque of 14.7 Nm. Check the lock plate for damages after repair to carefully straighten it before assembly because this action protects the radiator through proper reassembly and stops water leaks. Insert fresh O-rings and tanks into the assembly before checking that no external materials exist inside the lock plate groove. After this, use a soft-faced hammer to strike the lock plate until all gaps disappear. The Special Service Tool 09230-01010 and 09231-14010 requires adjustment of its stopper bolt to 8.4 millimeters (0.331 inch) before applying the lock plate caulk by pressing the tool against the plate and measuring its height at 8.45 to 8.85 millimeters (0.3327 to 0.3484 inch). Install a new O-ring into the drain plug after tightening it while stuffing the inlet and outlet pipes with Special Service Tool: 09230-01010. The radiator tester should deliver 177 kPa pressure (1.8 kgf/cm2, 26 psi) while submerged underwater to detect leaks after performing a swishing motion to eliminate trapped air bubbles.
