2001 Honda Prelude Engine, Cooling and Exhaust Engine Timing Belt Service and Repair Manual

Removal and Installation REMOVAL NOTE: * Turn the crankshaft pulley so the No. 1 piston is at Top Dead Center (TDC) before removing the belt. * Inspect the water pump after removing the timing belt. * Replace the timing belt and timing balancer belt at 105,000 miles (168,000 km) according to the maintenance schedule (normal conditions/severe conditions). If the vehicle is regularly driven in one or more of the following conditions, replace the timing belt and timing balancer belt at 60,000 miles (U.S.A.) 100,000 km (Canada). * In very high temperatures (over 110°F, 43°C). * In very low temperatures (under -20°F, -29°C). 1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio’s preset buttons. 2. Disconnect the battery negative terminal first, then the positive terminal. 3. Remove the wheel well splash shield. 4. Loosen the adjusting bolt, locknut and mounting bolt, then remove the Power Steering (P/S) pump belt. 5. Remove the alternator terminal and connector. 6. Loosen the adjusting bolt, mounting bolt and lock nut, then remove the alternator belt. 7. Remove the side engine mount. NOTE: * Support the engine with a jack before removing the side engine mount and upper bracket assembly is removed. * Make sure to place a cushion between the oil pan and the jack 8. Remove the dipstick and the tube. 9. Remove the cylinder head cover. NOTE: The procedures in steps 10 and 11 are for reusing the timing belt. For replacing the timing belt, skip these procedures and go to step 12. 10. Use an open-end wrench to loosen the maintenance bolt. If it cannot be loosened with an open-end wrench, a box wrench can be used after removing the lock pin. NOTE: Use of a tool should be limited to initial loosening only 11. Unscrew the maintenance bolt by hand until it stops. The auto-tensioner bracket is now fixed. NOTE: * Never use a tool to unscrew the maintenance bolt after initial loosening it. * If the auto-tensioner has been extended and the timing belt cannot be installed, remove the auto-tensioner, compress it and reinstall it. 12. Remove the middle cover. NOTE: Do not use the middle cover to store removed items. 13. Remove the pulley bolt and crankshaft pulley

2002 Mitsubishi Montero Limited Removing Drive Belt Auto Tensioner/ Aligning Timing Marks

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. Race engine to 3000 RPM several times. Stop engine. After engine cools, refill radiator and coolant reservoir tank.

Let the engine reach its normal operating temperature (the cooling fan cycle twice). Let the engine idle (throttle fully closed and with all electrical items off) for 10 minutes. 6. If you are working on a 2001 Civic 2-door EX, do the Cruise Control Learn Procedure. Drive the vehicle, and set the cruise control above 40 miles per hour. Continue driving the vehicle for 5 to 10 minutes. NOTE: You can use a smog/chassis dynamometer to do this step instead of driving the vehicle. Do not do this step with the vehicle on a lift.
