CAUTION: If the engine encounters a catastrophic failure, the engine oil cooler must be replaced or damage to the new engine and/or components could result.
1. Perform the fuel system pressure release procedure. Refer to FUEL DELIVERY, GAS, STANDARD PROCEDURE .
2. Disconnect and isolate the negative battery cable (1).
3. Remove the cylinder head(s). Refer to CYLINDER HEAD, REMOVAL.
NOTE:
When the oil pan is removed, a new oil pan gasket and the integral windage tray assembly must be installed, the old gasket cannot be reused.
4. Remove the oil pan. Refer to PAN, OIL, REMOVAL.
5. Remove and discard the oil pan gasket/windage tray (3).
6. If necessary, remove the ridge on top of the cylinder bores with a reliable ridge reamer before removing pistons from engine block. Be sure to keep the tops of the pistons covered during this operation.
CAUTION: When removing and installing the pistons and connecting rods, do not damage the piston oil cooler jets. If the jets are bent, engine damage may occur.
7. Remove the piston oil cooler jet(s) retaining bolt(s) (2) and remove the piston oil cooler jet(s) (1).
CAUTION: Do not use a number stamp or a punch to mark connecting rods or caps, as damage to connecting rods could occur.
CAUTION: Care must be taken not to damage the fractured rod and cap joint face surfaces as engine damage may occur.
CAUTION: Care must be taken not to nick crankshaft journals as engine damage may occur.
NOTE:
Connecting rods and bearing caps are not interchangeable and should be marked before removing to ensure correct reassembly.
8. Mark the connecting rod and bearing cap position using a permanent ink marker or scribe tool.
NOTE:
Pistons and connecting rod assemblies must be removed from the top of the engine block. When removing the piston and connecting rod assemblies from the engine, rotate the crankshaft so each connecting rod is centered in the cylinder bore.
9. Remove the connecting rod cap and carefully remove the piston from the cylinder bore, repeat this procedure for each piston being removed.
10. Immediately after removing the piston and connecting rod, install the bearing cap on the mating connecting rod to prevent damage to the fractured cap and rod surfaces.
11. Carefully remove the piston rings from the piston(s), starting from the top ring down.
