Oil Pump Replacement
Sometimes referred to as Oil Pump, Replace Oil Pump, Oil Pump Replace
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.

What to watch out for
Low oil pressure can be caused by a plugged oil pick-up screen or leaking seals in the engine. It is important that these items are inspected before replacing the oil pump.
Why this happens
Low oil pressure can be caused by using the incorrect type on engine oil. Be sure to check with your owners manual for the correct type for your engine and climate.
The oil pressure should be checked before condemning an oil pump. A good quality repair shop will perform an oil pressure check and record the readings on the repair order.
