Radiator

Engine coolant draining should begin before removing upper two bolts from hood latch support as well as the upper Radiator seal. In the next step the technician disconnects inlet and outlet Radiator hoses from the Radiator before safely positioning them aside. The plastic cap covering the transaxle oil cooler pipe quick connectors needs sliding off while the cooler quick connect tool (J 41623-A) should be used to disconnect the upper and lower transaxle oil cooler pipe connections from the Radiator. After disconnecting the A/C Condenser from the Radiator you must remove all the overflow hose and cooling fans. Start by detaching the upper mounting brackets of the Radiator before you can remove it from the car. Install the new Radiator by first positioning its bottom section into the lower mounts and afterward securing the upper mounting brackets and bolts which should be tight to 10 nm. Use only a 15 mm (0.6 inch) bolt for the condenser-to-end tank connection because it is the sole securement method that prevents damaging the Radiator end tank. Attach the A/C Condenser to the Radiator then fasten its mounting bracket bolts at 13 nm (10 ft. Lbs.). Use a gentle pull on the filler ports to check the cooler pipe fittings are secured after listening for a "click" sound during insertion of the upper and lower transaxle oil cooler components. Insert plastic joint covers onto quick connect fittings before you install the cooling fans together with both the overflow tube and inlet and outlet hose assemblies into the Radiator. Fasten the upper Radiator seal and the upper two bolts from the hood latch support by applying 9 nm torque (80 inch lbs.). Finally, fill the cooling system.
