2005 Toyota MR2 Spyder Parts Questions & Experts Answers

• Q: How to service and repair a radiator on 2005 Toyota MR2 Spyder?

  A: You should start radiator maintenance by unscrewing the drain plug together with its o-ring. The clamp of Special Service Tool: 09230-01010 must be mounted to the overhaul handle before users adjust the stopper bolts until dimension "B" reaches between 0.2 and 0.3 mm (0.008 - 0.012 inch) to avoid harm. You can remove lock plate caulk through tool operation by moving the handle until the stopper bolts activate. A soft-faced hammer should be used to lightly strike the radiator bracket in order to extract the tanks while removing their O-rings. Check the lock plate for damage by inspecting its sides; use pliers to fix any deformations since such damage will result in water leakage through the bottom of the groove. Recaulking is possible twice but replacing the radiator core will become necessary after that. New O-rings and tanks need installation for reassembly while preventing foreign items from entering the lock plate groove while keeping the O-ring straight and untwisted. A soft-faced hammer should tap the lock plate to close any gaps that might exist. Special Service Tools 09230-01010 and 09231-14010 include a punch assembly which needs adjusting the stopper bolt to maintain 8.4 mm (0.331 inch) dimension "B". Apply the tool to the lock plate then firmly grip the handle until it stops while preventing the wedge from embedding near brackets and pipes. To finalize lock plate preparation check its height at point H which should range between 7.4 to 7.8 millimeters (0.2913-0.3071 inch) before making additional adjustments. The new O-ring must be fitted onto the drain plug correctly followed by installing the drain plug. Use Special Service Tool: 09230-01010 to plug the inlet and outlet pipes while testing with 177 kPa (1.8 kgf/cm2, 26 psi) radiator cap pressure. Draw a water bath around the radiator while checking for any fluid escape while you gently move the radiator through the water to detect simulated leaks.
