The oil pump is an essential piece of equipment that keeps your Tacoma running. It lubricates the engine by keeping the oil circulating. Without this lubrication, the engine wouldn't run. An oil pump is usually located in the oil pan. If you want to change the oil pump and replace it with a new one, roll up your sleeves and get ready for some dirty work.

Instructions

    1

    Drive your Toyota Tacoma up onto ramps or lifts so you have room to work as you pull out the oil pump. You could also use a jack, but make sure you brace the front wheels so they don't roll. In addition, set the emergency break firmly into position so the car doesn't roll.

    2

    Relieve the fuel system pressure and then disconnect the negative and positive battery cables and remove the battery. Drain the engine coolant as well as the engine oil. Take the engine out of the vehicle and safely store it in a suitable holding device.

    3

    Remove the oil level gauge guide, the water inlet, the belt tensioner, the idler pulley No. 2 sub assembly, the idler pulley No. 1 sub assembly, the crankshaft pulley, the lower oil pan, the strainer and pickup tube, the upper oil pan, the ignition coil assembly, the cylinder head cover, the camshaft timing oil control valve assembly, the VVT sensor, the oil filter bracket sub assembly, the timing chain case cover retaining bolts, the cover from the engine, the O-ring from the left cylinder head, the three bolts, the oil pipe, the two O-rings, the seven oil pump cover bolts, the gears from the timing chain case cover and the oil pump relief valve.

    Cover your new oil pump relief valve with fresh engine oil to lubricate it. Install the plug, using a new gasket and torque it to 36 ft-lb.

    5

    Coat the oil pump gears with clean engine oil also. Line up these gears in the timing chain case cover with the identification marks facing oil pump cover side. Insert the cover. Take turns tightening each bolt in order, torquing them to 80 in-lb. Add the oil pipe and tighten the bolts to 80 in-lb.

    6

    Put in a new front case oil seal then insert a new O-ring onto the left cylinder head. Apply continuous beads of seal packing (0.12 to 0.16 inches in diameter) using part number 08826-00080 on all the parts except the water pump. Add the timing chain case cover bolts, tightening the bolts and the nuts by taking turns until they reach 17 ft-lb.

    Re-install the engine. Add fresh engine coolant and engine oil. Start your engine and check your working area for leaks.
