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

  A: The radiator removal begins with draining the engine coolant followed by removal of the engine under covers. The first step involves disconnecting both No.1 and No.2 electric cooling fan connectors as well as the upper and lower radiator hoses and radiator reservoir hose and A/T: 2 oil cooler hoses. First extract the two bolts then proceed to remove the upper radiator supports before moving onto the radiator assembly and finally the 2 lower radiator supports. To remove the electric cooling fan from the radiator start by unfastening its 5 bolts. During disassembly step first remove the drain plug with O-ring then set up Special Service Tool: 09230-01010 by placing the claw onto the overhaul handle to adjust the stopper bolts for a dimension "B" between 0.2 to 0.3 mm (0.008 to 0.012 inch). The same tool should be used to remove the lock plate caulking while pulling the handle until the stopper bolts stop moving. Begin by carefully taping the bracket holding the radiator tank to detach it along with its O-ring. Additional steps for vehicles with an automatic transmission include removing the lower oil cooler tank by unfastening its two nuts, two plate washers and finally removing the oil cooler and its accompanying two O-rings. The lock plate must undergo inspection for damage which requires repairing all deformations for correct reassembly because the radiator has a maximum replacement limit of two recaulking cycles. For installation reassembly attach two new O-rings to the oil cooler then join it to the lower tank by applying two plate washers and two nuts while torquing to 8.34 Nm (85 kgf-cm, 74 inch lbs.). You should run a soft-faced hammer against the lock plate to close gaps but always inspect that no foreign objects exist in the lock plate groove and replace all O-rings and tanks. Adjust Special Service Tool: 09230-01010 to achieve a stopper bolt length of 8.4 mm (0.331 inch) before applying sealant to the lock plate on surface areas that exclude brackets and tank ribs. When the caulking process is finished check the lock plate height stands between 7.40 - 7.80 mm (0.2913 - 0.3071 inch). Connect a fresh O-ring to the drain plug before securing it in place. Next check for any leaks by tightening the drain plug after plugging the inlet and outlet pipes while using Special Service Tool: 09230-01010. Then apply a test pressure of 177 kPa (1.8 kgf/cm2, 26 psi) using a radiator cap tester to check water leaks during the submersion of the radiator in water. The electric cooling fan mounting requires 5 bolts tightened to 6 Nm (60 kgf-cm, 53 inch lbs.) before connecting the radiator assembly through installation of the 2 lower supports to body brackets followed by using 2 upper supports with 13 Nm (130 kgf-cm, 9 ft. lbs.). Installation consists of first mounting the A/C condenser with four bolts and afterward connecting all radiator hoses including the upper section, lower section and the radiator reservoir line with the A/T oil coolers' two hoses. The procedure concludes by connecting the No.1 and No.2 electric cooling fan connectors followed by reinstalling engine under covers and filling the system with engine coolant and checking for any leaking fluid.
