Oil Pump Replacement

The engine oil pump generates the oil pressure needed to keep internal engine parts lubricated. If the oil pump fails, major engine damage can occur.

The oil pump may be located in the oil pan or operated by the timing belt (or timing chain).

  • If the oil pump is located in the engine oil pan, the pan must be removed to replace the oil pump.
  • If the timing belt operates the oil pump, the engine's fan belts and timing components must also be removed in order to gain access to the oil pump.
  • If the oil pump is driven directly by the crankshaft, the accessory belts, timing cover, timing belt, and crankshaft pulley must be removed in order to access the oil pump.
