Aligning Timing Marks (2001-02 Montero) Courtesy of MITSUBISHI MOTOR SALES OF AMERICA. Installation (2001-02 Montero) 1. Place auto-tensioner in soft-jawed vise to SLOWLY compress the push rod. If there is a plug at the base of the auto-tensioner body, place flat washer around plug so it will not contact vise jaw. 2. Slowly compress auto-tensioner push rod until holes in push rod and auto-tensioner housing are aligned. Insert a locking pin into the alignment holes. Install auto-tensioner on engine. 3. Ensure all timing marks are still aligned. See Fig. 11 . Install timing belt on crankshaft sprocket, idler pulley, left bank camshaft sprocket, water pump pulley, right bank camshaft sprocket, and tensioner CAUTION: Never compress the auto-tensioner too fast, or the push rod will be damaged. WARNING: Right bank camshaft can easily turn from applied spring pressure. Be careful not to pinch fingers when installing timing belt. 2002 Mitsubishi Montero Limited MITSUBISHI 3.5L V6 – SOHC many waters gallery pulley. Take all slack out of timing belt. 4. Loosen the tensioner pulley center bolt. Using Tensioner Pulley Wrench (MD998767), rotate tensioner pulley against timing belt. Temporarily tighten tensioner pulley center bolt. Using Crankshaft Pulley Spacer (MD998769), turn crankshaft 1/4 turn counterclockwise. Turn crankshaft 1/4 turn clockwise. Ensure all timing belt marks are still aligned. 5. Loosen tensioner pulley center bolt. Position tensioner pin holes at bottom of tensioner. Install Tensioner Pulley Wrench (MD998767) on tensioner pulley. See Fig. 12 . Using torque wrench, apply 39 INCH lbs. (4.4 N.m) of torque (counterclockwise direction) to tensioner pulley. Tighten tensioner center bolt to specification while holding tensioner pulley stationary. See TORQUE SPECIFICATIONS . 6. Remove locking pin from auto-tensioner. Turn crankshaft 2 revolutions clockwise and align all timing marks. DO NOT rotate counterclockwise. 7. Wait for at least 5 minutes, then check auto-tensioner push rod protrusion. To check push rod protrusion, measure clearance between body of auto-tensioner and bottom of tensioner pulley bracket arm. Clearance should be 0.15-0.20″ (3.8-5.0 mm). If protrusion is not correct, repeat timing belt tensioning procedure. Ensure all timing marks are aligned. 8. Install timing belt covers. See Fig. 10 . Install crankshaft pulley. Tighten crankshaft pulley bolt to specification. See TORQUE SPECIFICATIONS . Install accessory mount assembly on front of engine. See Fig. 13 . See TORQUE SPECIFICATIONS . To install remaining components, reverse removal procedures. See Fig. 7 and Fig. 8 . Adjust drive belts to proper tension. 9. When filling cooling system, use 50/50 mix of coolant and water. Open bleed screw on top of thermostat housing. Slowly fill cooling system until coolant flows out of bleed hole. Install bleed screw. Start engine and run to normal operating temperature.
