Oil pump replacement instructions needed

Hi,

There are two different possible engines in this vehicle. According to my manual, they follow the same directions.

The attached pics will correlate with the directions.

The oil pump on this engine is located behind the crankshaft pulley. Here are the directions for removal:

Hi,

The oil pump isn't located in the oil pan. However, I believe there are a couple of bolts that go up through the oil pan to the bottom of the cover assembly.

Keep in mind, that is only the pump which I'm referring to. There is still a pick-up tube and screen in the oil pan.

Let me know if that helps.

Take care,

Joe
