    Q:
    How to remove and install an Oil Pump on V8 engine on Chevrolet Tahoe? Posted by Dima Z.
    A:
    Remove the timing chain cover and oil pan. Remove the oil pump pick-up tube mounting nuts and bolts and lower the pick-up tube and screen assembly from the vehicle. Remove the oil pump retaining bolts and slide the pump off the end of the crankshaft. Remove the oil pump cover and withdraw the rotors from the pump body. Clean the components with solvent, dry them thoroughly, and inspect for any obvious damage. Also, check the bolt holes for damaged threads and the splined surfaces on the crank-shaft sprocket for any apparent damage. If any of the components are scored, scratched, or worn, replace the entire oil pump assembly. There are no serviceable parts currently available. Prime the pump by pouring clean engine oil into the pick-up tube hole, while turning the pump by hand. Position the oil pump over the end of the crankshaft and align the teeth on the crankshaft sprocket with the teeth on the oil pump drive gear. Making sure the pump is fully seated against the block. Install the oil pump mounting bolts and tighten them to the proper torque specifications. Install a new O-ring on the oil pump pick-up tube, then fasten it to the oil pump and the engine block main studs. 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. Run the engine and check for oil and coolant leaks. Also, check the oil pressure.
