• Q: How to service and repair a radiator on 2004 Toyota Sequoia?

  A: Service and repair of the radiator starts with removing 4 bolts and 2 pipes as well as 2 bushings and 2 radiator supports until you reach the radiator cap and drain plug. Special Service Tool 09230-01010 requires installation of the claw onto the overhaul handle followed by stopper bolt adjustment for B dimension between 0.2 to 0.3 millimeters (0.008 to 0.012 inch) to safeguard against claw damage. Press the tool handle until it stops due to the stopper bolt to uncaulk the lock plates. Use a soft-faced hammer to strike the radiator port which will remove the tank while removing the O-ring. By inspecting the lock plate for damage you should use pliers to fix any deformation because a damaged groove might result in water leakage. A radiator should receive only two recaulkings until necessary core replacement becomes needed. Place fresh O-rings and tanks onto the system while checking for external items in the lock plate groove and maintaining the smooth O-ring placement. A soft-faced hammer should be used to tap the lock plate until all gaps become completely eliminated. Follow these instructions to adjust the stopper bolt of Special Service Tools 09230-01010 and 09231-14010 for dimension "B" to measure 8.4 mm (0.34 inch). Press the tool into the lock plate while squeezing the handle until the stopper bolt activates and prevent staking near the ports and flanges. Measure the lock plate height (H) to verify its range between 7.4 - 7.8 mm (0.2959 - 0.3119 inch) after caulking. Make adjustments if necessary. Insert a new drain plug O-ring before placing soapy water and screwing on the drain plug. To check for water leaks use Special Service Tool: 09230-01010 while applying pressure of 147 kPa (1.5 kgf/cm2, 21 psi) using a radiator cap tester on the inlet and outlet pipes that are plugged. Swirling the radiator through water creates conditions for false leak detection so it is essential to do this before performing tests. Handle the 4 bolts to the 2 pipes by torquing them to 12.7 Nm (130 kgf-cm, 9 ft. lbs.) while installing them with the 2 bushings and 2 radiator supports before reattaching the radiator cap.
