  Q: How to replace an oil pump assembly on four cylinder engine for Saturn LS and LS1?

  A: Drain the engine oil. Remove the drivebelt. Loosen the right-front wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Remove the right front wheel. Remove the engine front cover. Working on the backside of the engine cover, loosen the oil pump cover screws a little at a time until they're all loose. Lift the oil pump cover from the oil pump assembly. When all of the screws are loose, remove the cover. Note any identification marks on the rotors and withdraw the rotors from the pump body. If no marks can be seen, use a permanent marker and make your own to ensure that they will be installed correctly. Thoroughly clean and dry the components. Inspect the rotors for obvious wear or damage. If either rotor, the pump body or the cover is scored or damaged, the complete oil pump assembly must be replaced. Also check the inner-to-outer rotor tip clearance, the outer rotor-to-housing clearance, and the rotor-to-cover side clearance. Use a feeler gauge to check the inner-to-outer rotor tip clearance and the outer rotor-to-housing clearance. Use a straightedge and a feeler gauge to check the rotor-to-cover clearance. If the oil pump components are in acceptable condition, dip the rotors in clean engine oil and install them into the pump body with any identification marks positioned as noted during disassembly. Remove the oil pressure relief valve components from the oil pump body. Thoroughly clean and dry the components. Inspect the components for obvious wear or damage. Install them in the correct order. Install the rotors into the housing with the hub of the inner rotor facing the engine front cover. The inner rotor hub must be installed correctly or the engine front cover will not fasten properly. Install the oil pump cover and screws and tighten by hand until snug. Then tighten the screws gradually and evenly to the specific torque. Install the engine front cover. Fill the engine with fresh engine oil. Install a new oil filter. Refill the cooling system. Start the engine and check for leaks. Run the engine and make sure oil pressure comes up to normal quickly. If it doesn't, stop the engine and find out the cause. Severe engine damage can result from running an engine with insufficient oil pressure!

  Q: How to replace an oil pump in V6 engine for Saturn LS and LS1?

  A: Raise the front of the vehicle and support it securely on jackstands. Disconnect the cable from the negative terminal of the battery. Drain the engine oil. Remove the drivebelt. Remove the Timing Belt cover and the timing belt. Remove the rear timing belt cover. Remove the air conditioning compressor and tie it out of the way with a piece of wire. Remove the alternator. Remove the oil pan-to-oil pump mounting bolts. Remove the crankshaft sprocket. Remove the oil pump mounting bolts and separate the pump from the engine block. Working on the backside of the oil pump, loosen the oil pump cover mounting bolts gradually and evenly. Loosen each bolt in several steps. Remove the oil pump cover. Note any identification marks on the rotors and withdraw the rotors from the pump body. Thoroughly clean and dry the components. Inspect the rotors for obvious wear or damage. If either rotor, the pump body or the cover is scored or damaged, the complete oil pump assembly must be replaced. If the oil pump components are in acceptable condition, dip the rotors in clean engine oil and install them into the pump body with any identification marks positioned as noted during disassembly. Remove the oil pressure relief valve components from the oil pump body. Thoroughly clean and dry the components. Inspect the components for obvious wear or damage. Install them in the correct order. Using a seal driver, install a new seal into the bore of the pump. Install a new gasket onto the engine block. Coat the oil pump side of the gasket with an aerobic sealant. Be careful to apply a thin layer of sealant and keep any sealant from entering the oil passageways. Prime the oil pump prior to installation. Pour clean oil into the pick-up port and turn the pump by hand. Install the oil pump to the engine. Apply a thread locking compound to the oil pump bolts and tighten the bolts to the specific torque. The oil pump mounting bolts must be retorqued after the alternator bracket has been installed onto the oil pump/engine block. The remainder of installation is the reverse of removal procedure. Reconnect the battery. Fill the engine with the correct type and quantity of oil. Start the engine and check for leaks.
