Remove the oil pan. While supporting the oil pump, remove the pump-to-rear main bearing cap bolt. On some models, the oil pan baffle must be removed first, since it's also held in place by the pump mounting 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. Position the pump on the engine and make sure the slot in the upper end of the driveshaft is aligned with the tang on the lower end of the distributor shaft. The distributor drives the oil pump, so it is absolutely essential that the components mate properly. Install the mounting bolt and tighten it. Install the oil pan and refill with fresh oil. The remainder of assembly is the reverse of the disassembly procedures.

Take out the oil pan. Remove the pump-to-rear main bearing cap bolt while supporting the oil pump. There is a single bolt that holds the oil pump to the rear main cap. Take out the bolt, then take out the oil pump. Drop it down and remove with the pump driveshaft. For almost all models, an oil pump driveshaft aligns with an oil pump shaft using a rigidly-hard nylon sleeve. Put this sleeve on the oil pump driveshaft. If it is not there, look for its pieces in the oil pan, take them out from there and get a new one for use on an oil-pump driveshaft. Examine whether or not damage or looseness exist in both the screen and pickup tube too much of which can make them fit tightly at all to the oil-pump itself . In case you have a new one, please ensure that this item has been connected to a relevant place within an engine . Place it over an engine and ensure that upper slot of drive shaft fits into lower tang of distributor shaft . The distributor drives the oil pump; therefore, good mating is important between these components. Fasten a mounting bolt and tighten it until it reaches required torque. Lastly mount your pan back onto your engine.

The oil pan is taken off first before removing and installing the oil pump. Take out the oil pump mounting bolt from the main bearing cap after that. The block should be separated from the oil pump and pick-up assembly. If there is a problem with the latter, replace it with a new one. When doing a complete engine overhaul, it is advisable to use a new oil pump rather than reusing the old one or rebuilding it. The oil pickup tube of an oil pump should be checked for any looseness if it's pressed into the body of the oil pump. It's dangerous to attempt tightening a loose one; instead, replace the entire pump assembly. Put the oil pump in place by turning its shaft to align tang of gear with slot on lower end of oil pump drive shaft. The retainer on lower side of the oil pump drive shaft will enable easy movement of the entire thing over to its position. If not, remove it twisting tang until properly aligned with driveshaft slot in pump. Tighten up this mount using its bolt you earlier detached. Put back your vehicle's engine and start placing some engine before checking if there are any leaks.

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.

After removing the oil pan, take out the two oil pump mounting bolts and the pick-up tube bracket nut from the main bearing cap bolt.

To install the oil pump, simply reverse the removal procedure for both engine types.

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 the distributor drives the oil pump and proper mating of these components is essential.

If any components are scored, scratched, or worn, replace the entire oil pump assembly, as no serviceable parts were available at the time of writing.

While supporting the oil pump, remove the pump-to-rear main bearing cap bolt.

If the oil pump pickup tube is loose, it should be replaced with the complete pump assembly, rather than attempting to fix it.

Install and align the timing chain cover, then install the oil pan. The remainder of installation is the reverse of removal. Add oil and coolant as necessary.

The timing chain cover and oil pan need to be removed.
