1. Installation Review and Vehicle Preparation. (a) Review the entire instruction instructions provided before beginning the installation (b) Review the parts list/kit contents to ensure that all parts are present before beginning the installation. If any items are missing contact Technical Support at (800) 688-5912 before proceeding. (c) Remove any low-octane fuel from the vehicle. Ensure that ONLY 91 octane or higher unleaded gasoline is used. (d) Place the vehicle onto vehicle hoist. (e) Protect the vehicle with protection blankets over the fenders and front of the vehicle. (f) Disconnect and remove the battery. (g) When draining the cooling system into a clean container in Step 3, save this coolant as it will be reused. CAUTION: To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal expansion will cause the hot engine coolant and steam to blow out from the radiator. (h) All parts that are removed and not reused should be saved for the customer, i.e., “discard” means to save for the customer 2. Cover Removal. (a) Remove the engine V-bank cover by Lifting the front of the cover and pulling away from the firewall (Fig 2-1). Discard these parts. (b) If installed, remove the No. 1 engine under cover (Fig 2-2) by removing the 3 screws and 5 bolts. Save these parts for reuse. 3. Drain Engine Coolant. CAUTION: Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns. (a) Loosen the radiator drain cock plug (Fig. 3-1). (b) Remove the radiator cap. Then drain the coolant from the radiator into a clean container so it can be reused (Fig. 3-1). (c) Loosen the 2 cylinder block drain cock plugs (Fig.3-1). Then drain the coolant from the engine and save for reuse. (d) Tighten the 2 cylinder block drain cock plugs. Torque: 13 Nm (10 ft lbf) 4. Fan and Shroud Removal. (a) Remove the upper radiator hose. Mark the radiator end of this hose with a marker or tape. This hose will be re-installed inverted and the mark will help identify the ends. (b) Loosen the 4 nuts holding the fluid coupling fan (Figs. 4-1). (c) Remove the fan/generator V-rib belt. Discard this belt as it will be replaced by a new belt. (d) Disconnect the reservoir hose from the upper radiator tank. (e) For vehicles with Trailer Towing System: Detach the claw to open the No. 1 hose clamp on the side of the fan shroud (Fig 4-2). (f) Remove the 2 bolts holding the fan shroud (Figs 4-3). Remove the 4 nuts of the fluid coupling fan, and then remove the shroud together with the coupling fan. Retain these parts for reuse. Temporarily re-install the 4 nuts to keep the pulley in place (reference Fig 4-1). Do not tighten. CAUTION: Be careful not to damage the radiator core. It is helpful to protect the radiator core with a piece of cardboard to prevent damage during subsequent steps. 5. Air Cleaner Lower Box Replacement. (a) Remove the air cleaner hose by disconnecting the vacuum and ventilation hoses and loosening the 2 clamps. (Fig 5-1). Discard this hose and clamps
