Where is the oil filter on a 1992 Dodge 2500 van?

The oil filter location on a 1992 Dodge 2500 van depends entirely on the engine it has. Dodge 2500 vans from that year could have several different engines (e.g., V6, various V8s).

To find it, you need to identify your engine. The engine type is usually visible on a sticker under the hood or on the driver's side dashboard. Once you know the engine type (e.g., 3.9L V6, 5.2L V8, 5.9L V8), you can consult a repair manual specific to that engine for the precise oil filter location.

A quick online search using "1992 Dodge 2500 [engine type] oil filter location" should yield images and diagrams.

Without knowing the engine, I cannot give you a definitive answer.
