Installation Procedure
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
- Dip the crankshaft bearing cap bolts in clean engine oil.
- Place the crankshaft bearing inserts into the crankshaft bearing cap and into the engine block.
- Lubricate the crankshaft main bearing surface with clean engine oil.
- Install the crankshaft.
- Install the crankshaft main bearing caps. Apply a small amount of sealer GM P/N 1052942 (Canadian P/N 10953466) to the rear of the #4 crankshaft main bearing cap sealing surface.
- Install the crankshaft main bearing cap bolts.
Tighten: Use the J 45059 in order to tighten the crankshaft main bearing cap bolts to 50 N. See Special Tools and Equipment .m (37 lb ft) plus 77 degrees.
- Measure the crankshaft end play.
- Thrust the crankshaft forward or rearward.
- Insert a feeler gage between the number 3 crankshaft bearing and the bearing surface of the crankshaft and measure the bearing clearance. The proper crankshaft end play clearance is 0.06-0.21 mm (0.002-0.008 in).
- If the bearing clearance is not within specifications, inspect the thrust surfaces for nicks, gouges or raised metal. Minor imperfections may be removed with a fine stone.
- Install the crankshaft position sensor into the side of the engine block.
- Apply threadlock GM P/N 12345382 (Canadian P/N 10953489) or the equivalent to the crankshaft position sensor stud threads.
- Install the crankshaft position sensor stud.
Tighten: Tighten the crankshaft position sensor stud to 11 N.m (98 lb in).
- Install the crankshaft position sensor shield and nut.
Tighten: Tighten the crankshaft position sensor shield nut to 11 N.m (98 lb in).
IMPORTANT:
Ensure that the crankshaft bearing cap bolt holes and the crankshaft bearing cap mating surfaces are clean and dry.
NOTE:
Upper and lower inserts may be different. Do not obstruct any oil passages.
IMPORTANT:
The crankshaft bearing inserts will project slightly when put into place. Ensure that the bearing inserts project an equal distance on both sides. Ensure that the insert tangs are engaged.
NOTE:
In order to prevent the possibility of cylinder block or crankshaft bearing cap damage, the crankshaft bearing caps are tapped into the cylinder block cavity using a brass, lead, or a leather mallet before the attaching bolts are installed. Do not use attaching bolts to pull the crankshaft bearing caps into the seats. Failure to use this process may damage a cylinder block or a bearing cap.
NOTE:
Refer to Fastener Notice in Cautions and Notices.
