Torque: 124 lb.in (14 Nm)
-
NOTE: The cylinder head assembly service part does not come with the front oil cover, the bolts or the gasket. It will be necessary to install a new gasket and the original front oil cover and bolts onto the new cylinder head assembly.
If necessary, install a new gasket, the front oil cover and the bolts.
Torque: 89 lb.in (10 Nm)
- Install Special Service Tool: 303-572 (T97T-6000-A) Remover/Installer, Cylinder Head.
- Install a new cylinder head gasket.
-
NOTE: Do not tighten the cylinder head bolts at this time.
With the aid of an assistant, install the cylinder head.
- Install the bolts finger tight.
-
NOTE: Be sure to tighten the bolts in 3 stages.
Tighten the bolts in sequence shown in 3 stages.
Torque: Stage 1: 30 lb.ft (40 Nm) | Stage 2: 90 deg. Stage 3: 90 deg.
- Remove Special Service Tool: 303-572 (T97T-6000-A) Remover/Installer, Cylinder Head.
- Install the balance shaft drive gear onto LH camshaft.
-
NOTE: Finger tighten at this time. The bolt will be final tightened after the RH timing chain is installed.
Install the LH camshaft sprocket and a new bolt finger-tight.
-
NOTE: Prior to installation, inspect the tensioner-sealing bead for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner or engine damage may occur.
Using a vise, compress the tensioner plunger and install the Hydraulic Chain Tensioner Retaining Clip (PN# 1L3Z-6P250-AA) on the tensioner to hold the plunger in during installation. Use the General Equipment: Vise
-
NOTE: There are 61 links in each timing chain.
If copper (colored) links are not visible, mark 2 links on one end and 1 link on the other end, and use as timing marks.
- Install the LH timing chain guide and the bolts.
Torque: 89 lb.in (10 Nm)
- Install the lower end of the LH timing chain, aligning the single colored link and the timing mark.
-
NOTE: Be sure the upper half of the timing chain is below the tensioner guide dowel.
Position the LH timing chain on the camshaft sprocket with the 2 chain (colored) links and the timing marks aligned.
-
NOTE: The LH timing chain tensioner arm has a bump near the dowel hole for identification.
Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner and the bolts.
Torque: 18 lb.ft (25 Nm)
- Remove the Hydraulic Chain Tensioner Retaining Clip from the LH timing chain tensioner.
-
NOTE: Prior to installation, inspect the tensioner-sealing bead for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner or engine damage may occur.

-
NOTE: Be sure the chain link and crankshaft sprocket timing marks are aligned.NOTE: The lower half of the timing chain must be positioned above the dowel.
Install the RH (outer) timing chain on the crankshaft sprocket.
- Position the timing chain on the camshaft sprocket. Make sure the 2 copper-colored (marked) links align with the camshaft sprocket timing mark.
- Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner and the bolts.
Torque: 18 lb.ft (25 Nm)
- Remove the Hydraulic Chain Tensioner Retaining Clip from the RH timing chain tensioner.
- Install the crankshaft sensor ring onto the crankshaft.
-
NOTE: Only use hand tools to tighten the camshaft sprocket bolt or damage may occur to the camshaft or camshaft sprocket.
Tighten the LH camshaft sprocket bolt in 2 stages.
Torque: Stage 1: 30 lb.ft (40 Nm) | Stage 2: 90 deg.
-
NOTE: Lubricate the balance shaft journals with clean engine oil.
