Disconnect the negative battery cable.
Detach the ignition coil and module electrical connection. Remove the coil and module assembly-to-camshaft housing bolts, then remove the assembly by lifting it straight up.
NOTE
Use spark plug wire removal tool J 36011 to disengage any connector that may have stuck to the spark plugs. Use the tool by first twisting, then pulling up on the connector assembly.

Disengage the electrical connection from the oil pressure switch.
For vehicles equipped with an automatic transaxle, remove the transaxle fluid level indicator tube assembly from the exhaust camshaft cover, then position it aside.
Disconnect, but do not remove from the vehicle, the timing chain housing at the exhaust camshaft housing.
Remove the exhaust camshaft cover and gasket, then discard the gasket. Be sure to loosen the housing bolts in the reverse order of the tightening sequence.
Clean all old gasket debris from the cover mating surfaces.

To install: Position new camshaft housing-to-cover seals. No sealant is needed.
Apply pipe sealant 1052080 (or equivalent thread locking sealer) to the threads of the camshaft housing and cover retaining bolts.
Position the cover onto the housing, then tighten the bolts, in sequence, to specification. Tighten the camshaft housing-to-cylinder head bolts to 11 ft. Lbs. (15 Nm) plus 90 °, and the camshaft housing cover-to-camshaft housing bolts to 11 ft. Lbs. (15 Nm) plus 30 °.
Tighten the timing chain housing retainers.
Install the transaxle fluid level indicator tube assembly to the exhaust camshaft cover.
Attach the oil pressure switch electrical connector.
Reinstall any spark plug boot connectors that may have been stuck to a spark plug, back onto the ignition coil and module assembly.
Position the coil and module assembly over the spark plugs then push it straight down making sure it is firmly and properly seated.
Clean off any lubricant on the coil and module-to-camshaft housing bolts. Apply pipe sealant 1052080 (or equivalent thread locking sealer) to the bolts, then tighten them to 16 ft. Lbs. (22 Nm) on the 2.3L engine and 11 ft. Lbs. (15 Nm) on the 2.4L engine. Plus 30 °.
Attach the ignition coil and module assembly electrical connector.
Connect the negative battery cable, then start the engine and inspect for leaks.

Intake Camshaft

Disconnect the negative battery cable.
Detach the ignition coil and module assembly electrical connections.
Unfasten the ignition coil and module assembly-to-camshaft housing bolts, then remove the assembly by pulling it straight up.

NOTE
Use a spark plug wire removal tool J 36011 or equivalent to remove any connector that may have stuck to the spark plugs. Use the tool by first twisting, then pulling up on the connector assembly

Remove the power steering pump pulley.
Unfasten the vacuum line from the fuel pressure regulator and fuel injector harness connector.
Disconnect the fuel line retaining clamp from the bracket on top of the intake cam housing.
Unfasten the fuel rail-to-camshaft housing retaining bolts, then remove the fuel rail from the cylinder head. Be sure to cover the injector openings in the cylinder head, cover the injector nozzles and leave the fuel lines attached and position the fuel rail aside (on top of the master cylinder).
Disconnect the timing chain housing but do not remove form the vehicle.
Unfasten the cam housing cover-to-housing retaining bolts and the cam housing-to-cylinder head bolts.
Use the reverse of the tightening procedure (in the accompanying figure) when loosening the camshaft housing-to-cylinder head bolts.
Push the cover off the housing by threading four of the housing-to-head retaining bolts into the tapped holes in the cover. Make sure to tighten the bolts evenly remove the cover from the vehicle.
Remove and discard the cover-to-housing seals and clean the mating surfaces.
To install: Position new seals on the camshaft cover.
Apply pipe sealant 1052080 (or equivalent thread locking sealer) to the camshaft housing and cover retaining bolt threads. Using J 366660, install the bolts. Tighten the camshaft housing-to-cylinder head bolts to 11 ft. Lbs. (15 Nm) plus 90 ° then tighten in sequence the camshaft housing cover-to-camshaft housing bolts to 11 ft. Lbs. (15 Nm) plus 30 °.
Fasten the timing chain housing.
Uncover fuel injectors, then lubricate new injector O-ring seals with clean engine oil and install on the injectors.
Uncover the injector openings in the cylinder head, then install the fuel rail onto the cylinder head. Install the fuel rail-to-cylinder head retaining bolts and tighten to 19 ft. Lbs. (26 Nm).
Install the fuel line retaining clamp and retainer to the bracket on top of the cam housing.
Connect the vacuum line to the fuel pressure regulator. Attach the fuel injector harness connector.
Lubricate the inner surface of the camshaft seal with clean engine oil, then install the seal into the camshaft housing using a seal installer tool such as J 36015, or equivalent.
Using the same tool J 36015 or equivalent, install the power steering pump drive pulley onto the intake camshaft.
Install the power steering pump assembly and the drive belt. Adjust tension to specification.
Fasten any spark plug boot connector assembly that stuck to a spark plug back onto the ignition coil and module assembly.
Position the coil and module assembly over the spark plugs, then push the assembly straight down. Make sure it is properly seated.
Clean off any loose lubricant from the coil and module assembly-to-camshaft housing bolts. Apply pipe sealant 1052080 (or equivalent thread locking sealer), onto the bolts, then tighten the bolts to 11 ft. Lbs. (15 Nm).
Attach the coil and module electrical connector.
Connect the negative battery cable, then start the engine and inspect for oil leaks.
