Timing Chain and Sprocket Installation: Installation
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Install the crankshaft sprocket.
- Apply prelube GM P/N 12345501 (Canadian P/N 992704) or the equivalent to the crankshaft sprocket thrust surface.
- Install the timing chain tensioner.
- Install the timing chain tensioner bolts and tighten to 21 N.m (15 lb ft).
- Using the EN-47719: compressor, fully collapse the tensioner, and place the tensioner retaining pin into the retaining hole (1).
- Align the dowel in the camshaft position actuator with the dowel hole in the camshaft.
- Draw the camshaft sprocket onto the camshaft using the mounting bolts and tighten the bolts to 16 N.m (12 lb ft).
- Remove the tensioner retaining pin.
- Coat the crankshaft and camshaft sprocket with engine oil.
CAUTION:
Refer to Fastener Caution
.
CAUTION:
Use only a Torx Plus® Bit when removing or installing the camshaft position actuator fasteners (1). The Torx Plus® design differs from typical Torx® fastener. Use of a standard Torx® bit on Torx Plus® fasteners may result in a rounded out fastener head or incorrect faster torque.
NOTE:
DO NOT use any type of threadlocking compound on the camshaft position actuator mounting bolts. Usage of a threadlocking compound on the threads could lead to contamination of the camshaft position actuator, possibly resulting in potential damage to the actuator.
