How to Remove and Install the Oil Pump in four cylinder engine on Chevrolet Astro?

Pull off the oil pan, then, it is required to unscrew the two oil pump installation bolts as well as the pick-up tube nut on the main bearing cap bolt. Remove the oil pump and pick-up assembly from the block. If the pump is bad, then the best action is to replace the pump with a new one; when doing a total engine rebuild, always fit a new oil pump and do not consider reusing or reconditioning the old one. For installation, rotate the shaft until the gear tang fits into the slot on the lower end of the oil pump driveshaft allowing the pump to slid over the lower bushing. If it doesn't fit properly then try to regulate the tang in some way so that it fits rightly. Fasten the pump to the block with the mounting bolts and the nut of the tube bracket, till reaching the specified torque. Last, but not the least reinstall the oil pan, put some oil and start the vehicle and look for the signs of leakage.

How to remove and install the timing chain cover and oil pump assembly in V8 engine on Chevrolet Camaro?

At first, undo the nut and bolt of the mounting of pick-up tube of oil pump then gently pull down the pick-up tube and screen assembly out of the car, one has to be careful in the removal of the retaining nuts of the oil pick-up tube-to-stud and also the bolt joining the tube with the pump. Afterward, unbolt the remaining crankshaft oil deflector nuts, un-thread the deflector and finally, the oil pump bolt to release the end of the pump on the crankshaft. To perform an inspection the oil pump cover must be removed, and the rotors pulled out of the pump body, after which all the parts must be cleaned with solvent and carefully dried while executing the inspection with attention to the bolt holes and the splined surface on the crankshaft sprocket. If any of the components is scored, scratched or worn, replace the oil pump assembly since no individual parts are available. When installing this pump, start the pump by pouring clean engine oil in the pick-up tube hole as the pump turns. Place the oil pump with its flange over the end of the crankshaft so that the teeth on the crankshaft sprocket will mesh with those on the oil pump drive gear and install the pump firmly to the block. Finally in the oil pump, tighten the bolts that hold the oil pump to specified torque, and replace the worn out oil pump O-ring also the pick-up tube should be properly fastened to the oil pump and the engine block main studs so that the pick-up tube-to-oil pump bolts are tightly fastened free from air streaming into the oiling system. Last, place the timing chain cover and the oil pan, follow the reverse process of the removal, fill the oil and coolant, start the engine and check for leakage and the oil pressure.

How to remove and install the oil pump in 4.3L V6 and 5.0L,5.7L,7.4L V8 engine on Chevrolet Express?

For 2014 and earlier models, begin by removing the oil pan. While supporting the oil pump, unscrew the bolt holding the oil pump to the rear main bearing cap, then remove the pump. Lower the pump and take it out along with the pump driveshaft, ensuring that the hard nylon sleeve used for alignment is in place on the oil pump driveshaft; if not, check the oil pan for pieces of the sleeve, clean them out, and obtain a new sleeve. Inspect the screen and pickup tube for damage or looseness, ensuring a light fit onto the oil pump. If a new oil pump is being installed, confirm that the pump driveshaft is properly mated with the shaft inside the pump. Position the pump on the engine, aligning the slot in the upper end of the driveshaft with the tang on the lower end of the distributor shaft, as proper mating is essential. Install and tighten the mounting bolt to the specified torque, then reinstall the oil pan. For 2018 and later models, start by removing the timing chain cover and the oil pan. Install special tool EN-51257 against the timing chain tensioner and the edge of the oil pump body, tightening the mounting bolts securely. Remove the oil pump mounting bolts and slide the pump off the crankshaft. If the oil pump is being removed without replacement, ensure that special tool EN-51267 is installed to the engine block and against the pump before removal, remaining in place until reinstallation; failure to do so necessitates installing a new oil pump. Remove the oil pump cover and withdraw the rotors, cleaning the components with solvent, drying them thoroughly, and inspecting for damage, including checking bolt holes and splined surfaces for wear. If any components are scored or worn, replace the entire oil pump assembly. Prime the pump by pouring clean engine oil into the pickup tube hole while turning the pump by hand. Position the oil pump over the crankshaft, aligning the teeth on the crankshaft sprocket with those on the oil pump drive gear, ensuring the pump is fully seated against the block. Push the pump body upward to maintain contact with the tool while tightening the bolts, ensuring no gap exists between the oil pump housing and the tool; if a gap is present, loosen the bolts, push the pump against the tool, and retighten. Install and tighten the oil pump mounting bolts to the specified torque, then align and install the timing chain cover and the oil pan. Complete the installation in reverse order of removal, adding oil and coolant as necessary, running the engine, and checking for leaks and oil pressure.

Chevrolet Oil Pump Parts Questions & Experts Answers

Q: How to Remove and Install the Oil Pump in four cylinder engine on Chevrolet Astro?
A: Pull off the oil pan, then, it is required to unscrew the two oil pump installation bolts as well as the pick-up tube nut on the main bearing cap bolt. Remove the oil pump and pick-up assembly from the block. If the pump is bad, then the best action is to replace the pump with a new one; when doing a total engine rebuild, always fit a new oil pump and do not consider reusing or reconditioning the old one. For installation, rotate the shaft until the gear tang fits into the slot on the lower end of the oil pump driveshaft allowing the pump to slid over the lower bushing. If it doesn't fit properly then try to regulate the tang in some way so that it fits rightly. Fasten the pump to the block with the mounting bolts and the nut of the tube bracket, till reaching the specified torque. Last, but not the least reinstall the oil pan, put some oil and start the vehicle and look for the signs of leakage.

Q: How to remove and install the timing chain cover and oil pump assembly in V8 engine on Chevrolet Camaro?
A: At first, undo the nut and bolt of the mounting of pick-up tube of oil pump then gently pull down the pick-up tube and screen assembly out of the car, one has to be careful in the removal of the retaining nuts of the oil pick-up tube-to-stud and also the bolt joining the tube with the pump. Afterward, unbolt the remaining crankshaft oil deflector nuts, un-thread the deflector and finally, the oil pump bolt to release the end of the pump on the crankshaft. To perform an inspection the oil pump cover must be removed, and the rotors pulled out of the pump body, after which all the parts must be cleaned with solvent and carefully dried while executing the inspection with attention to the bolt holes and the splined surface on the crankshaft sprocket. If any of the components is scored, scratched or worn, replace the oil pump assembly since no individual parts are available. When installing this pump, start the pump by pouring clean engine oil in the pick-up tube hole as the pump turns. Place the oil pump with its flange over the end of the crankshaft so that the teeth on the crankshaft sprocket will mesh with those on the oil pump drive gear and install the pump firmly to the block. Finally in the oil pump, tighten the bolts that hold the oil pump to specified torque, and replace the worn out oil pump O-ring also the pick-up tube should be properly fastened to the oil pump and the engine block main studs so that the pick-up tube-to-oil pump bolts are tightly fastened free from air streaming into the oiling system. Last, place the timing chain cover and the oil pan, follow the reverse process of the removal, fill the oil and coolant, start the engine and check for leakage and the oil pressure.

Q: How to remove and install the oil pump in 4.3L V6 and 5.0L,5.7L,7.4L V8 engine on Chevrolet Express?
A: For 2014 and earlier models, begin by removing the oil pan. While supporting the oil pump, unscrew the bolt holding the oil pump to the rear main bearing cap, then remove the pump. Lower the pump and take it out along with the pump driveshaft, ensuring that the hard nylon sleeve used for alignment is in place on the oil pump driveshaft; if not, check the oil pan for pieces of the sleeve, clean them out, and obtain a new sleeve. Inspect the screen and pickup tube for damage or looseness, ensuring a light fit onto the oil pump. If a new oil pump is being installed, confirm that the pump driveshaft is properly mated with the shaft inside the pump. Position the pump on the engine, aligning the slot in the upper end of the driveshaft with the tang on the lower end of the distributor shaft, as proper mating is essential. Install and tighten the mounting bolt to the specified torque, then reinstall the oil pan. For 2018 and later models, start by removing the timing chain cover and the oil pan. Install special tool EN-51257 against the timing chain tensioner and the edge of the oil pump body, tightening the mounting bolts securely. Remove the oil pump mounting bolts and slide the pump off the crankshaft. If the oil pump is being removed without replacement, ensure that special tool EN-51267 is installed to the engine block and against the pump before removal, remaining in place until reinstallation; failure to do so necessitates installing a new oil pump. Remove the oil pump cover and withdraw the rotors, cleaning the components with solvent, drying them thoroughly, and inspecting for damage, including checking bolt holes and splined surfaces for wear. If any components are scored or worn, replace the entire oil pump assembly. Prime the pump by pouring clean engine oil into the pickup tube hole while turning the pump by hand. Position the oil pump over the crankshaft, aligning the teeth on the crankshaft sprocket with those on the oil pump drive gear, ensuring the pump is fully seated against the block. Push the pump body upward to maintain contact with the tool while tightening the bolts, ensuring no gap exists between the oil pump housing and the tool; if a gap is present, loosen the bolts, push the pump against the tool, and retighten. Install and tighten the oil pump mounting bolts to the specified torque, then align and install the timing chain cover and the oil pan. Complete the installation in reverse order of removal, adding oil and coolant as necessary, running the engine, and checking for leaks and oil pressure.
