Where is the oil filter?

Where is the oil filter in a 1991 Blazer?

I had a 91 blazer 4.3w 4x4 4dr. It was on the drivers side near the front of the engine compartment mounted near the fender. Probably the easiest filter I ever changed.

It will be on the pass side of the engine or if your Blazer has a relocation kit, it should be around the radiator on the driver side. If I remember right it should be on the pass side of the engine like it is on the 92 W/T 4.3l.
