How to Replace an Oil Pump in a Toyota Tundra

An oil pump is a necessary tool for the survival of the engine. It keeps the engine components in the Toyota Tundra lubricated. Without lubrication, an engine is destroyed. In most cases you don't need to replace an oil pump, but in some cases, such as an engine overhaul, you might want to.

Instructions

1

Drive your Toyota Tundra 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

Disconnect the battery cable and remove the engine undercover. Take out the crankshaft timing pulley and the front differential (if you have 4WD). Drain the oil from the engine.

3

Remove the following components in this order: the timing belt and crankshaft gear, the oil cooler tube and clamp (if you have automatic transmission), the stiffener plate, the flywheel housing undercover and dust cover, the rear end cover and dust cover, and the starter wire clamp.

4

Find the crankshaft position sensor and disconnect it then remove the oil pan from the bottom of the engine. Remove the oil strainer, the oil baffle plate, and the oil pump body (it has eight bolts). Finally, take the O-ring off the cylinder block.

5

Install your new oil pump by applying Seal Packing PN 08826-00080 to it then adding a new O-ring to the groove of the cylinder block. Line up the new oil pump to the crankshaft so the spline teeter of the drive rotor connects with the large teeth of the crankshaft.

6

Tighten the bolts on the oil pump to 15 ft-lb. Add the CKP and the oil pan baffle plate. Reinsert the oil strainer with a new gasket, tightening those bolts to 13 ft-lb.

7

Return the components your removed in reverse order, finishing up by connecting the negative battery cable once again. Add fresh oil and start the engine of your Toyota Tundra and look carefully for leaks in your work area.
