TIMING BELT Removal 1. Disconnect negative battery cable. Remove upper engine torque strut attaching bolts and remove engine torque strut. See Fig. 5 . Remove engine torque strut bracket from strut tower. On PT Cruiser (Turbo), discharge and evacuate A/C system. Disconnect A/C lines at junction block near upper timing belt cover. 2. On all models, remove upper timing belt cover bolts and remove cover. See Fig. 6 . Raise vehicle on hoist and remove right front wheel. Remove splash shield. See Fig. 7 . Remove accessory drive belts. Remove crankshaft damper. See Fig. 8 . Remove pencil strut. See Fig. 2 . Remove lower engine torque strut. See Fig. 5 . 3. Disconnect exhaust system front pipe from manifold. Disconnect A/C pressure switch at rear of compressor housing. Lower vehicle and support engine with a jack. If not done previously, discharge and evacuate A/C system. Disconnect A/C lines at junction block. Remove screw attaching ground strap to strut bracket. Remove torque strut bracket from strut tower. Remove upper radiator closure panel. Without disconnecting lines from power steering pump, remove pump and bracket and set pump aside. 4. With engine properly supported, remove right engine mount through-bolt. See Fig. 5 . Raise engine with jack until engine support bracket bolts are accessible, and remove engine support bracket. See Fig. 9 . Remove lower timing belt cover bolts and remove cover. See Fig. 6 . CAUTION: When aligning crankshaft and camshaft timing marks, always rotate engine from crankshaft. Camshaft should not be rotated after timing belt is removed, or damage to valve components may occur. CAUTION: Crankshaft sprocket TDC mark is located on the trailing edge of sprocket tooth. Failure to align trailing edge of sprocket tooth to TDC mark on oil pump housing will cause camshaft timing marks to be misaligned. 5. Before removal of timing belt, rotate crankshaft until TDC mark on oil pump housing aligns with the TDC mark on crankshaft sprocket (trailing edge of sprocket tooth). See Fig. 10 . 6. Loosen timing belt tensioner lock bolt, and insert a 6-mm Allen wrench into hexagon opening located on top plate of belt tensioner pulley. See Fig. 11 . Rotate top plate clockwise until there is enough slack in timing belt to allow for removal. If reusing old timing belt, mark belt with arrow to indicate original direction of rotation. Remove timing belt. CAUTION: If timing belt was damaged due to incorrect rotating tracking (alignment), belt tensioner pulley and bracket must be replaced as an assembly.

NOTICE: Always turn the crankshaft clockwise. (c) Check that the timing marks of the camshaft timing pul- leys and No.3 timing belt cover are aligned. If not, turn the crankshaft pulley 1 revolution (360°). (d) Remove the crankshaft pulley bolt. IF REUSING TIMING BELT, CHECK INSTALLATION MARKS ON TIMING BELT Check that there are 3 installation marks and front mark on the timing belt. If the installation and front marks have disappeared, before re- moving the timing belt, place 3 new installation marks on the timing belt to match the timing marks of the timing pulleys, and place a new front mark on the timing belt. 18. 19. REMOVE TIMING BELT TENSIONER Alternately loosen the 2 bolts, and remove them, the belt ten- sioner and dust boot. 20. REMOVE TIMING BELT 21. (a) REMOVE RH CAMSHAFT TIMING PULLEY Using SST, loosen the pulley bolt. SST 09960–10010 (09962–01000, 09963–01000) Remove the bolt, knock pin and timing pulley. (b) 22. (a) REMOVE LH CAMSHAFT TIMING PULLEY Using SST, loosen the pulley bolt. SST 09960–10010 (09962–01000, 09963–01000) Remove the bolt, knock pin and timing pulley. (b) 23. REMOVE NO.2 IDLER PULLEY Remove the bolt and idler pulley. 24. REMOVE NO.1 IDLER PULLEY Using a 10 mm hexagon wrench, remove the pivot bolt, idler pulley and plate washer. 25. REMOVE CRANKSHAFT TIMING PULLEY Remove the timing pulley. HINT: If the pulley cannot be removed by hand, use SST and a service bolt to remove the timing pulley. SST 09950–50011 (09951–05010, 09952–05010, 09953–05020, 09954–05011)

Ensure camshaft and crankshaft timing marks are still aligned. Outer marks on sprockets should be aligned with rocker cover surface. Verify timing chain timing mark alignment, if necessary. See Fig. 2 . Install timing belt tensioner pulley. Install timing belt. If reusing old belt, ensure belt is installed in original direction of rotation. 2. Loosen timing belt tensioner bolt, allowing tensioner pulley to contact belt. Tighten timing belt tensioner pulley bolt. Rotate crankshaft one turn clockwise. Realign camshaft and crankshaft timing marks. 3. Adjust timing belt tension until .15-.24″ (4-6 mm) deflection is present midway between idler pulley and camshaft sprocket, with a force of 4.4 lbs. (2 kg) applied to belt. 4. Rotate engine clockwise 2 revolutions. Ensure timing marks are still aligned and proper belt tension still exists. Install timing belt covers. Install crankshaft pulley. To complete installation, reverse removal procedure. Adjust drive belt to proper tension.

Remove front timing belt cover (Refer to COVER-FRONT TIMING BELT). 2. Inspect both sides of the timing belt. Replace belt if any of the following conditions exist. See Fig. 326: Hardening of back rubber back side is glossy without resilience and leaves no indent when pressed with fingernail. Cracks (4) on rubber back. Cracks or peeling (1) of canvas. Cracks on rib root. Cracks on belt sides. Missing teeth (2). Abnormal wear (7) of belt sides. The sides are normal if they are sharp as if cut by a knife. Vehicle mileage or time at component maintenance requirement. (Refer to LUBRICATION & MAINTENANCE ) 3. If none of the above conditions are seen on the belt, the front timing belt cover can be installed (Refer to COVER-FRONT TIMING BELT). TIMING VERIFICATION

1. Disconnect negative battery cable. Remove engine undercover. Place wooden block between jack and oil pan, and raise engine slightly. Remove engine mount assembly near timing belt cover. 2. Remove clamp for power steering return hose near timing belt cover. Remove all drive belts and tensioner pulley bracket. See Fig. 1 . Remove power steering and water pump pulleys. Rotate crankshaft clockwise so that No. 1 cylinder is at TDC of compression stroke. Remove crankshaft pulley. CAUTION: DO NOT rotate crankshaft counterclockwise. Ensure timing marks are aligned. If reusing timing belts, mark timing belts for direction of rotation. 3. Remove upper timing belt cover and gasket. Remove stub bolt of engine support bracket, and remove center timing belt cover. Remove lower timing belt cover. NOTE: Camshaft sprocket dowel pins will be in 12 o’clock position when timing marks are correctly aligned. 4. Ensure camshaft, crankshaft and oil pump sprocket timing marks are aligned. See Fig. 2 or Fig. 3 . Loosen tensioner pulley center bolt. Move tensioner to relieve timing belt tension. Remove timing belt. Remove timing belt auto tensioner. See Fig. 1 . 5. Remove plug from left side of cylinder block. Install a .31″ (8.0 mm) diameter Phillips screwdriver into the hole against balance shaft. See Fig. 4 . Screwdriver must go in at least 2.36″ (60 mm) or more. If screwdriver will only go in about .79-.98″ (20-25 mm) before striking balance shaft, turn sprocket one revolution and align timing mark. Keep screwdriver in place until timing belt is installed. This ensures balance shaft driven by oil pump sprocket remains in correct position. 6. To remove timing belt “B” (balance shaft belt), hold crankshaft sprocket stationary with a spanner wrench. Remove crankshaft sprocket bolt. Using gear puller, remove outer crankshaft sprocket. 7. Remove crankshaft sensing blade (if equipped). See Fig. 5 . Loosen timing belt “B” tensioner bolt. If reusing timing belt “B”, mark direction of belt rotation for reassembly reference. Remove timing belt “B”.
