Installation 2.5L VIN H (Cirrus, Sebring Convertible & Stratus)
- Place automatic tensioner into vise, and SLOWLY compress plunger. When plunger is compressed into tensioner body, install locking pin through body and plunger holes to retain plunger until tensioner is installed. See Figure.
- Index tensioner in vise the same direction as installed. This will ensure proper pin orientation when tensioner is installed in engine. See Figure.
- Align crankshaft mark with timing mark on oil pump housing, then back off 3 notches before TDC. See Fig 1. This will position the crankshaft for timing belt installation. Set camshaft sprockets by aligning timing marks on sprockets with marks on rear timing belt cover. See Figure.
- Install timing belt on right (next to firewall) camshaft sprocket first. Install a spring clip to keep belt in position. Keeping belt taught, install belt under water pump pulley and then around front camshaft sprocket. Install spring clip on front sprocket and belt.
- Rotate crankshaft clockwise to TDC position. This will take the installation slack out of the timing belt and align the crankshaft timing marks to the TDC position. Continue routing belt around idler pulley, crankshaft sprocket, and tensioner pulley. Apply rotating force to crankshaft sprocket in clockwise direction to tension belt. Ensure camshaft timing marks and crankshaft TDC timing marks are aligned. See Figure.CAUTION: Ensure crankshaft has been rotated clockwise from the timing belt installation position to remove slack from timing belt and crankshaft timing marks are ALIGNED.
- Loosen tensioner pulley center bolt. Position tensioner pulley with pin holes facing down. Install Adapter (MD998767) or equivalent, and torque wrench, to tensioner pulley. See Figure. Apply 39 INCH lbs. (4.4 N.m) in a counterclockwise direction to tensioner. Tighten tensioner bolt to specification, without letting tensioner pulley rotate.
- With torque being applied to tensioner pulley, install automatic tensioner (with locking pin in place) to tensioner pulley bracket. Tighten bolts to specification. See TORQUE SPECIFICATIONS . Pull tensioner plunger locking pin.
- Rotate crankshaft 2 revolutions clockwise, and check alignment of timing marks. Install tensioner locking pin into automatic tensioner. Pin should slide in and out with no resistance. Even if locking pin cannot be easily inserted, belt tension is okay if automatic tensioner plunger projection is within .149-.177" (3.8-4.5 mm). Projection is measured between top edge of automatic tensioner housing and arm of tensioner pulley bracket. Retension timing belt, if necessary.
- Install timing belt covers. Install crankshaft vibration damper. Tighten crankshaft damper bolt to specification. See TORQUE SPECIFICATIONS .
- On all models, reverse removal procedure to complete installation. Adjust drive belts to proper tension. See appropriate COOLING SYSTEM SPECIFICATIONS article in ENGINE COOLING.
NOTE:
If reusing old timing belt, install in original direction of rotation.
