• Q: How to remove and reinstall a radiator on 2000 Toyota MR2 Spyder?

  A: Starting the radiator replacement requires draining engine coolant then removing the tool box followed by the luggage compartment trim box cover. Start by removing the radiator assembly which requires the elimination of 2 bolts and 2 nuts and 2 spare wheel carrier extensions and disconnecting the 2 electric cooling fan connectors and disconnecting the 2 radiator hoses followed by taking out 4 bolts and 2 radiator upper supports then dissolving the 2 radiator lower support bushings. The electric cooling fan needs to be detached from the radiator by removing its 2 bolts. To start disassembling use Special Service Tool: 09230-01010 by placing the claw onto the overhaul handle while adjusting stopper bolts to obtain dimension "B" at 0.2 - 0.3 mm (0.008 - 0.012 inch). Use the tool to unclean lock plates before gently tapping the radiator bracket and tank while also removing O-ring parts. Inspection of the lock plate must be followed by damage repair using pliers while noting that the radiator can have its seals replaced twice before necessary replacement. New O-rings and tanks need installation during reassembly while avoiding foreign objects in the lock plate groove and keeping the O-ring untwisted for proper assembly. A soft-faced hammer should be used to tap the lock plate until all gaps disappear. Follow these steps to assemble Special Service Tool: 09230-01010, 09231-14010 by adjusting the stopper bolt to reach 8.4 mm (0.331 inch) dimension. Use the tool to caulk the lock plate while verifying that the lock plate height falls between 7.4 to 7.8 mm (0.2913 to 0.3071 inch). Add a new O-ring before installing the drain plug onto its housing. Testing commences through drain plug tightening followed by installation of coolant reservoir together with toolkit Special Service Tool: 09230-01010 to seal the inlet and outlet pipes which are tested with 177 kPa pressure (1.8 kgf/cm2, 26 psi) radiator cap instrument while the radiator rests under water to detect possible leaks. For installation, attach the electric cooling fan to the radiator with 2 bolts, torquing to 5 Nm (51 kgf-cm, 44 inch lbs.), then install the radiator assembly by placing it in the body, installing the 2 radiator lower support bushings, securing the 2 radiator upper supports with 4 bolts torqued to 12.5 Nm (128 kgf-cm, 9 ft. lbs.), connecting the 2 radiator hoses, connecting the 2 electric cooling fan connectors, and installing the 2 spare wheel carrier extensions with 2 bolts and 2 nuts torqued to 8 Nm (82 kgf-cm, 70 inch lbs.). The technical procedure ends by adding cooling fluid while installing the luggage compartment trim box cover and tool box before checking for engine fluid leaks and reconfirming the correct coolant level.
