2002 Dodge Neon Power Steering Belt Service and Repair Manual

Power Steering Belt REMOVAL POWER STEERING PUMP AND AIR CONDITIONING COMPRESSOR BELT 1. Using a 17 mm wrench, rotate belt tensioner clockwise (Fig. 2) until belt can be removed from power steering pump pulley. Gently, release spring tension on tensioner. 2. Remove the drive belt (Fig. 3). Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt. INSPECTION Belt replacement under any or all of the following conditions is required: ^Excessive wear ^Frayed cords ^Severe glazing Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 6). NOTE: Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION NOTE: When installing drive belt on the pulleys, make sure that belt is properly routed and all V-grooves make proper contact with pulley grooves. POWER STEERING PUMP AND AIR CONDITIONING COMPRESSOR BELT 1. Install the drive belt (Fig. 3) over all the pulleys except for the power steering pump pulley 2. Using a 17 mm wrench, rotate belt tensioner clockwise (Fig. 2) until belt can be installed on the power steering pulley Release spring tension onto belt. 2002 Dodge Neon L4-2.0L VIN C Copyright © 2009, ALLDATA 9.90 Page 4 3. After belt is installed, inspect belt length indicator marks (Fig. 7). The indicator mark should be within the minimum belt length and maximum belt length marks. On a new belt, the indicator mark should align approximately with the nominal belt length mark


INSPECTION When inspecting serpentine drive belts, small cracks that run across the ribbed surface of the belt from rib to rib are considered normal. If the the cracks are running along the rib (rather across), this is not normal and the belt(s) must be replaced. ADJUSTMENT It is not necessary to adjust belt tension on the 5.2L or 5.9L engines and on the 2.5L and 4.0L engines (without power steering). These engines are equipped with an automatic tensioner. The tensioner maintains correct tension at all times. 2.5L and 4.0L Engines With Power Steering See Figures 1, 2, 3 and 4 If the vehicle is not equipped with power steering, it will be equipped with an idler pulley. If equipped with an idler pulley, refer to and follow the 5.2L/5.9L belt removal and installation procedure. Loosen the pump upper pivot bolt, lower locknut and pump adjusting bolt using a ratchet and 13mm socket or a 13mm box wrench. 1. Use a belt tension gauge placed in the middle of the belt being tested. Proper tension for a new belt is 180-200 lbs. (800-900 N) and 140-160 lbs. (623-712 N) for a used belt. 2. Tighten the pump adjusting bolt to achieve proper tension and recheck the belt tension. 3.

Loosen the pump upper pivot bolt, lower locknut and the pump adjusting bolt using a ratchet and 13mm socket or a 13mm box wrench. 2. Remove the belt. 3. To install: Install the belt. 4. Tighten the pump adjusting bolt to achieve proper tension. 5. Install the pump rear mounting bolts, pivot bolt and locknut. Tighten the bolts to 20. ft. lbs. (27 Nm). 6. Check the belt for proper tension. If tension is incorrect, refer to the adjustment procedure in this section. 7. 5.2L and 5.9L Engines See Figures 8, 9 and 10

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.


REPAIR PROCEDURE This repair is compatible with DaimlerChrysler’s Mobile Service Program and does not require hoists or other full service facility special equipment. 1. Remove the serpentine belt from around the idler pulley by rotating the tensioner clockwise ( Fig. 3 ). 2. Remove the purge duty cycle solenoid and wiring harness from the right side engine mount. 3. Remove the two right side engine mount insulator vertical fasteners and loosen the horizontal fastener. DO NOT remove the large nut in the center of the core of the insulator ( Fig. 4 ). 4. Remove the load on the engine mount by carefully supporting the engine with a floor jack. 5. Remove the vertical and horizontal fasteners from the engine side bracket. Remove the engine mount assembly. 6. Remove the idler pulley from the engine mounting bracket. ( Fig. 3 ). 7. Remove the engine mounting bracket. 8. Install a new engine mounting bracket. Torque the fasteners to 40-68 N.m (30-50 ft-lbs.). 9. Install the idler pulley to the engine mounting bracket. Torque the fastener to 40-68 N.m (30-50 ft-lbs.). 10. Properly route and position a serpentine belt onto all pulleys except the idler pulley (Use a new belt if there is any evidence of damage to the original one). 11. Rotate the belt tensioner clockwise until the belt can be installed onto the idler pulley. Slowly release the belt tensioner. 12. Install the engine mount; torque the assembly in the following order, engine mount to rail fasteners 68 N.m (50 ft-lbs.), vertical fastener 102 N.m (75 ft-lbs.), and horizontal fastener 150 N.m (111 ft-lbs.). 13. Install the purge duty cycle solenoid to the engine mount. 14. Start the vehicle and let it run for one minute then turn the engine off. 15. Verify the serpentine belt is properly aligned ( Fig. 1 ) 16. If the serpentine belt has moved toward the outboard edge of the idler pulley, further diagnosis will be required.
