Installation Procedure

WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the connecting rod bearings. Use the proper size bearings.
    1. 1.1. Install the bearings inserts into the connecting rod cap.
    2. 1.2. Lubricate the connecting rod bearings with engine oil.
  2. Install the piston and the connecting rod to the correct bore.
    1. 2.1. Slide a piece of 9.5 mm (0.375 in) fuel or vacuum hose over the connecting rod bolts. This protects the crankshaft journal during piston and connecting rod installation.
    2. 2.2. Stagger each piston ring end gap equally around the piston.
    3. 2.3. Lubricate the piston and the piston rings with engine oil.

    4. 2.4. Install J 8037  over the piston. Do not disturb the piston ring end gap location.
    5. 2.5. The piston must be installed so that the mark on the top of the piston faces the front of the engine.
    6. 2.6. Place the piston in its matching bore.
    7. 2.7. Tap the piston into its bore with a hammer handle. Guide the connecting rod to the connecting rod journal while tapping the piston into place.
    8. 2.8. Hold the J 8037  against the engine block until all the rings have entered the cylinder bore.
    9. 2.9. Remove the vacuum hose from the connecting rod bolts.

    Important:  Ensure that the connecting rod cap is properly oriented on the connecting rod.

  3. Install the connecting rod cap.
  4. Install the connecting rod bolt nuts.
    1. 4.1. Tighten the connecting rod bolt nuts to 25 N.m (18 ft lbs), then rotate 80 degrees using the J 36660-A  .
    2. 4.2. Install the remaining connecting rods and piston assemblies.
  5. Measure the connecting rod side clearance with a feeler gauge. The correct clearance is 0.150-0.450 mm (0.0059-0.0177 in).
  6. Install the crankshaft timing sprocket with the marked side facing out and rotate the crankshaft to align the keyway with the timing mark on the engine block.
