Removal & Installation
- Before servicing the vehicle, refer to the precautions in the beginning of this section.
- Drain the engine oil.
- Drain the cooling system.
- Relieve the fuel system pressure.
Remove or disconnect the following:
NOTEBefore detaching any hoses or connectors, note the locations for reassembly.
Negative battery cable
Air duct to intake manifold hose, collector hose, blow-by hose and vacuum hoses
- Set the No. 1 piston to Top Dead Center (TDC) of compression stroke by rotating the crankshaft.
Loosen the crankshaft pulley bolt while securing the ring gear so the crankshaft cannot rotate.
NOTEUse care not to damage the ring gear teeth.
Ring gear cover access plate
Crankshaft pulley using a suitable puller
- Hang the engine at the right and left side engine slingers with a suitable hoist.
Support the transaxle with jack.
Right side engine mounting and bracket
- Insert a seal cutter between the steel and aluminum oil pan.
Tapping the cutter with a hammer, slide it around the entire edge of the oil pan. Be careful not to damage the aluminum mating surface of the upper oil pan.
Steel oil pan and the oil strainer
- Insert a seal cutter between the aluminum oil pan and the engine block.
Tapping the cutter with a hammer, slide it around the entire edge of the oil pan. Be careful not to damage the mating surfaces of the oil pan or engine block.
Oil pan from the vehicle
Insert a suitable stopper pin for the left and right camshaft tensioners.
Left and right exhaust camshaft sprocket bolts. Be sure to hold the flats of the camshafts while removing the sprocket bolts
- Inspect the timing chain for excessive wear or damage and replace as necessary.
Install or connect the following:
Crankshaft sprocket with the mating mark facing out
Position the crankshaft to TDC of compression stroke and align the dowels of the camshaft sprockets to the 12 o'clock position in respect to the cylinder head.
Lower timing chain guide. The front mark on the guide should face upwards
On a work bench, align the marks on the intake and exhaust camshaft sprockets with the marks of the chain
Exhaust camshaft sprockets onto the dowel pin and torque the mounting bolts to 88-95 ft. lbs. (119-128 Nm). Be sure to secure the camshafts while tightening the bolts
Align the mating mark on the crankshaft with the matchmark (gold link) on the lower timing chain.
- Install the lower timing chain to the water pump sprocket.
Working counterclockwise, install the lower timing chain camshaft sprockets. Be sure to align the sprocket marks with the blue links of the timing chain during installation.
Intake sprocket and torque the bolts to 88-95 ft. lbs. (119-128 Nm). Be sure to secure the camshafts while tightening the bolts
- Torque the tensioner mounting bolt to 75-96 inch lbs. (8.4-10.8 Nm) and the guide bolts to 108-168 inch lbs. (13-19 Nm).
Apply a 0.102-0.142 in. (2.6-3.6mm) continuous bead of liquid gasket to all necessary areas as shown on the front timing cover.
Timing cover evenly and gently. Be sure to align the dowel pin holes
Torque the mounting bolts in sequence as follows:
- Bolts No. 1 and 2: 19-23 ft. lbs. (26-31 Nm).
Bolts No. 3-20: 105-121 inch lbs. (11.8-13.7 Nm).
NOTELeave the bolts unattended for 30 minutes or more after tightening. This will allow the liquid gasket to cure sufficiently.
Apply a 0.091-0.130 in. (2.3-3.3mm) continuous bead of liquid gasket to the water pump cover and install the cover. Torque the bolts to 84-108 inch lbs. (10-13 Nm).
- Fill the cooling system.
- Fill the engine with clean oil.
- Start the vehicle, check for leaks and repair if necessary.
