Timing Drive Components: Installation

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Rotate the crankshaft counterclockwise only. Do not rotate past the position shown in Fig 1 or severe piston and/or valve damage will occur.

Install the timing chain guides.
1. Position the LH timing chain guide.
2. Install the 2 LH timing chain guide bolts and tighten them to 10 Nm (89 lb-in).
3. Position the RH timing chain guide.
4. Install the 2 RH timing chain guide bolts and tighten them to 10 Nm (89 lb-in).

Position the LH timing chain on the camshaft sprocket. Make sure the copper-colored link aligns with the camshaft sprocket timing mark.

CAUTION: 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.
