2000-01 TIMING CHAINS 4.6L V8 – VIN W & 6

Removal
1. Remove valve covers. See VALVE COVERS . Remove front cover. See FRONT COVER . Remove crankshaft position sensor pulse wheel from crankshaft.
2. Rotate crankshaft until No. 1 piston is at TDC. This positions crankshaft keyway 45 degrees from vertical position. See Fig. 12 . Camshaft keyways will point toward crankshaft.
3. Install Camshaft Positioner (T96T-6256-AR) on flat area near rear of camshaft. See Fig. 9 . Remove retaining bolts, right chain tensioner, right tensioner arm and right chain guide. See Fig. 13 .
4. Remove right timing chain and crankshaft sprocket. Note direction of sprocket for installation reference. If necessary for clearance, remove retaining bolt, washer, camshaft sprocket and spacer.
5. Remove retaining bolts, left chain tensioner, left tensioner arm and left chain guide. See Fig. 13 . Remove left timing chain and crankshaft sprocket. Note direction of sprocket for installation reference. If necessary for clearance, remove retaining bolt, washer, camshaft sprocket and spacer.

Fig. 12: Identifying Timing Marks

Fig. 13: Exploded View Of Timing Chain & Components

Inspection
Inspect components for damage. Inspect friction surfaces on tensioner arms and chain guides for wear. Replace
components if necessary. If tensioner arms or guides are worn or damaged, remove and clean oil pan. Also,
replace oil pump screen cover and tube.

Installation
1. Install spacers, camshaft sprockets and retaining bolts. Ensure components are installed into original
locations. Tighten bolts to specification. See TORQUE SPECIFICATIONS .
2. Install camshaft positioner onto flat areas of camshaft if not previously installed. See Fig. 9 .
3. Install crankshaft sprocket for left timing chain. If copper links are not visible on timing chain, fold
timing chain in half and mark each end link for timing purposes. See Fig. 14 . These links will be referred
to as copper links when installing.
4. Ensure No. 1 piston is at TDC. This positions crankshaft keyway 45 degrees from vertical position. See Fig. 8 . Crankshaft keyway will point toward camshaft.
5. Install left timing chain on camshaft and crankshaft sprockets so copper link aligns with timing mark on
sprockets. See Fig. 12 . Install crankshaft sprocket for right timing chain. Ensure sprocket is properly
installed.
6. Install right timing chain onto camshaft and crankshaft sprockets so copper link aligns with timing mark
on sprockets. Install crankshaft positioner, to prevent crankshaft movement. Lubricate tensioner arms
with engine oil. Install tensioner arms. Install chain guides.
7. Chain tensioners must be bled down so tensioner plunger is compressed into housing before installing.
Place chain tensioner into soft-jaw vise. Using small pick, hold ratchet lock mechanism away from
ratchet stem. See Fig. 15 . Slowly close vise to depress tensioner plunger.
8. When tensioner plunger is compressed into housing, continue to hold ratchet lock mechanism and install
lock pin into hole on tensioner housing. Ensure ratchet stem is even with tensioner housing before
installing lock pin. See Fig. 15 .
9. Using “C” clamp or suitable tool, remove all slack from timing chain by applying pressure to tensioner
arm. While holding pressure on arm, install both chain tensioners and retaining bolts onto cylinder block.
Tighten bolts to specification. See TORQUE SPECIFICATIONS .
10. Remove lock pins from both chain tensioners. Ensure all timing marks align. See Fig. 12 . To check
accuracy of valve timing, remove No. 1 spark plug. Using a dial indicator, check for maximum intake
valve lift. Maximum intake valve lift should occur at 114 degrees after TDC.
11. To install remaining components, reverse removal procedure. Before installing valve cover, apply
silicone sealant at front cover-to-cylinder block areas.
12. When installing fuel lines, fit NEW fuel resistant “O” rings (Brown) on fuel lines. Lightly coat “O” rings
with clean engine oil before installing. Clean fittings, and replace garter spring (if necessary).
