A: The oil pump is an integral part of the engine. Generally, the oil pump is inside the lower part of the engine beside or below the crankshaft.
The oil pump is responsible for circulating oil under pressure to various engine components, such as the bearings, the camshaft, and the pistons. Oil circulation is important because it prevents the engine from overheating, ensuring the oil lubricates its parts.
First, you have to know where the oil pump is on your engine. Then you have to decide whether you have the gumption to replace it, because with very few exceptions, oil pumps are dreadfully difficult to replace. You also need to be sure the oil pump is causing whatever problem you’re trying to solve, and this can be tricky.
Some oil pumps are driven by flats on the front of the crankshaft, but you have to remove the timing chain or belt to access these. Other oil pumps are driven by the camshaft using a gear and a shaft, and the oil pan will need to be removed to access the pump.
