2004 Toyota MR2 Spyder Parts Questions & Experts Answers

• Q: How to service and repair a radiator on 2004 Toyota MR2 Spyder?

  A: Service and repair of the radiator starts with removing the drain plug together with its O-ring. Use Special Service Tool: 09230-01010 with the claw attached to the overhaul handle by adjusting stopper bolts to achieve "B" dimension between 0.2 - 0.3 mm (0.008 - 0.012 inch) for protection from potential damage. The same tool should be used to uncaulk the lock plates until they stop at the stopper bolts point. Finish the repair by using a soft-faced hammer to tap gently on the radiator bracket and remove the tanks along with O-rings. Inspects should check the lock plate for damage; minor groove side deformations require plier correction because damage to the groove bottom can ultimately lead to water leakage. The radiator has a maximum lifetime of two caulked treatments until it requires complete core replacement. The assembly process requires new O-rings with tanks but excludes foreign objects from the lock plate groove while ensuring the O-ring remains untwisted. To close any gaps use a soft-faced hammer for tapping the lock plate. Adjust the stopper bolt of Special Service Tool: 09230-01010 and 09231-14010 to reach dimension "B" at 8.4 mm (0.331 inch). Use the tool to press against the lock plate while avoiding staking adjacent to pipes and brackets and verify the height H (7.4-7.8 mm / 0.2913-0.3071 inch) needs adjustment when required. The installation process involves fitting a new drain plug O-ring followed by inspection of water leaks using the drain plug tightening procedure then the engine coolant reservoir installation and usage of Special Service Tool: 09230-01010 to block the pipes and a radiator cap tester application of 177 kPa (1.8 kgf/cm2, 26 psi) test pressure. A water soak test should be conducted on the radiator by completely submerging it for leak detection while gently stirring the water to stop air bubbles from pretending like leaks exist.
