How to replace the piston, connecting rod, and bearing in an engine on Chevrolet Cobalt?

An Oil Pan followed by a Cylinder Head must be removed before beginning the Piston connecting rod bearing replacement. A ring ridge needs removal so turn the Crankshaft to place the Piston in the bottom position before using a ridge reamer on top of the Piston while it is covered by a cloth. Proceed by rotating the Crankshaft to its peak stroke position before removing the cloth as well as the debris while preparing to record the connecting rod and cap assembly order. Next remove the connecting rod nuts and cap, discard the bolts and nuts then extract the connecting rod and Piston from the engine block by using (J 41742) and (J-43966-1). Heat the cylinder bores by washing them with hot water and detergent before treating them with oil and drying them with a clean cloth. Place engine oil on pistons together with rings and bores and bearings before fitting pistons into their original location with (J-43966-1), (J 43953) and (J 41742). Strike the Piston top gently with a wooden hammer handle in a way that features the stamped Piston mark aimed at the engine front. Retain (J 43953) against the motor block to let all rings pass into the barrel while you install the connecting rod caps onto their original connecting rods according to marked numbers. Use (J 45059) to achieve 100-degree extra tightening on the last pass after initial equal bolt torquing to 25 nm (18 lb ft). You must check the connecting rod side clearance with a feeler gauge as it should fall within the range of 0.070-0.370 mm (0.0027-0.0145 in). The last step includes adding the Cylinder Head together with the Oil Pan.

How to replace the piston, connecting rod, and bearing in an engine on Chevrolet Malibu?

Before replacing the Piston alongside connecting rod and bearing you must take out the Oil Pan together with the Cylinder Head. The Crankshaft needs to rotate until the Piston reaches its lowest position before placing a cloth on top of the Piston for using a ridge reamer which will eliminate the ring ridge. Once the Crankshaft reaches its top position remove the debris and cotton material. Use a marker to identify connecting rod and cap positions for later reinstallation before you take out connecting rod nuts and cap while discarding both items. The (J-43966-1) tool will help extract connecting rods and Piston pieces from the block. Clean the cylinder bores with hot water solutions of detergent or light honing before using engine oil followed by cleansing with a clean cloth. Use engine oil to coat the Piston along with its rings together with the cylinder bore and bearing surfaces before installing the Piston through its original bore with the (J-43966-1). Lightly tap the Piston top using a wooden hammer handle. Position the Piston stamping toward the front engine direction and apply the (EN-47836) device to the engine block to guide pistons into the bore before putting on connecting rod caps that match the previously noted rod numbers. Use even torque when tightening new connecting rod bolts and nuts to 25 nm (18 lb ft) before continuing with a second tightening sequence of 100 degrees through the use of the (J 45059). Create a side clearance measurement of the connecting rod by using a feeler gauge to verify values between 0.070-0.370 mm (0.0027-0.0145 in). The procedure ends with reinstallation of both the Cylinder Head and the Oil Pan.

Q: How to replace the piston, connecting rod, and bearing in an engine on Chevrolet Cobalt?
A:
An Oil Pan followed by a Cylinder Head must be removed before beginning the Piston connecting rod bearing replacement. A ring ridge needs removal so turn the Crankshaft to place the Piston in the bottom position before using a ridge reamer on top of the Piston while it is covered by a cloth. Proceed by rotating the Crankshaft to its peak stroke position before removing the cloth as well as the debris while preparing to record the connecting rod and cap assembly order. Next remove the connecting rod nuts and cap, discard the bolts and nuts then extract the connecting rod and Piston from the engine block by using (J 41742) and (J-43966-1). Heat the cylinder bores by washing them with hot water and detergent before treating them with oil and drying them with a clean cloth. Place engine oil on pistons together with rings and bores and bearings before fitting pistons into their original location with (J-43966-1), (J 43953) and (J 41742). Strike the Piston top gently with a wooden hammer handle in a way that features the stamped Piston mark aimed at the engine front. Retain (J 43953) against the motor block to let all rings pass into the barrel while you install the connecting rod caps onto their original connecting rods according to marked numbers.
