The lower retaining pins of the side air baffle need to be disconnected from the Radiator to reposition the condenser which lets you access the transmission oil cooler mounting bolts before removing them. You need hose clamp pliers (J38185) to lower the vehicle while disconnecting hose clamps which eliminates the Radiator outlet hose, Radiator inlet hose and surge tank inlet hose attached to the Radiator. Start by removing the Radiator support bracket bolts followed by the support brackets after which the upper air baffle retaining pins need to be disconnected from the Radiator before removing it. Fit the Radiator and install the upper air baffle retaining pins when performing an installation procedure. Fit the Radiator support brackets onto their positions before tightening them with Radiator support bracket bolts at 9 nm (80 inch lbs.). Attach each hose to the Radiator so it meets the required position using hose clamp pliers (J38185) while handling the surge tank inlet hose and Radiator inlet hose and Radiator outlet hose. Before mounting the vehicle elevate it to a position where you can tighten the toc mounting bolts to 5 nm (44 inch lbs.). Fasten the lower retaining pins of the side air baffle onto the Radiator before torquing both lower and upper condenser mounting bolts to 5.4 nm (48 inch lbs.). Place the electric fan along with filling your cooling system as the last step in the process.
