How to remove and install an oil pump on 4.3L V6 engine on Chevrolet Silverado?

Remove the oil pan. While supporting the oil pump, remove the pump-to-rear main bearing cap bolt. Lower the pump and remove it along with the pump driveshaft. If a new oil pump is installed, make sure the pump driveshaft is mated with the shaft inside the pump and a new driveshaft retainer is used. Position the pump over the dowel pins on the rear main cap and make sure the slot in the upper end of the driveshaft is aligned with the tang on the lower end of the oil pump driveshaft. The oil pump driveshaft drives the oil pump, so it is absolutely essential that the components mate properly. Also, note that no gasket is used between the oil pump and the rear main cap. Install the mounting bolt and tighten it to the torque specifications. Install the oil pan and refill the engine with fresh oil. The remainder of assembly is the reverse of the disassembly procedures.

Chevrolet Silverado Oil Pump

Chevrolet Silverado Oil Pump is responsible for keeping the truck's V8 heart safe. It forces oil under pressure through the bearings, pistons, and the camshaft, reducing friction and taking away heat. To move a lubricant, the Oil Pump draws it from the sump through a mesh strainer, forcing it through the filter and, if fitted, a cooler, then critical passages where pressure switches or sending units monitor flow for the dash light or gauge. Within the block, this Oil Pump is also applied to provide hydraulic force for small actuators. Across generations, Chevrolet trucks such as the Silverado have applied three main crank-driven styles. The direct drive Oil Pump envelopes the crankshaft and rotates with a gear mounted to the crank end, providing for compact packaging and accurate alignment. Gear drive and chain drive versions mount next to the crank, with meshed gears or a sprocket and chain set, which makes it easy to service, but it requires additional parts that have to be kept unworn for steady pressure. A less common style of crankcase-mounted style has a separate driveshaft with hex ends that can round off if neglected. Racing or high-rev builds will occasionally change out to a high-volume Oil Pump to satisfy looser bearing clearances. Regular examination of the housing, gears, relief valve, and pickup screen keeps every Chevrolet and every Silverado engine protected.

Each OEM Chevrolet Silverado Oil Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Oil Pump Assembly
12710303
Q: How to remove and install an oil pump on 4.3L V6 engine on Chevrolet Silverado?
A:
Remove the Oil Pan. While supporting the oil pump, remove the pump-to-rear main bearing cap bolt. Lower the pump and remove it along with the pump driveshaft. If a new oil pump is installed, make sure the pump driveshaft is mated with the shaft inside the pump and a new driveshaft retainer is used. Position the pump over the dowel pins on the rear main cap and make sure the slot in the upper end of the driveshaft is aligned with the tang on the lower end of the oil pump driveshaft. The oil pump driveshaft drives the oil pump, so it is absolutely essential that the components mate properly. Also, note that no gasket is used between the oil pump and the rear main cap. Install the mounting bolt and tighten it to the torque specifications. Install the oil pan and refill the engine with fresh oil. The remainder of assembly is the reverse of the disassembly procedures.
