Where are the spark plugs located in a 1994 Chevy van?

The spark plug location in a 1994 Chevy van depends entirely on the engine it has. Chevy vans from that year came with a variety of engines (e.g., 4.3L V6, 5.0L V8, 5.7L V8, and possibly others depending on trim level and market).

To find the spark plugs, you must first identify your engine's displacement (e.g., 4.3L, 5.0L, 5.7L). This information is usually found on a sticker under the hood or in your owner's manual.

Once you know the engine size, you can:

* Consult a repair manual specific to your van's year and engine. This is the most reliable method. A Haynes or Chilton manual will have diagrams showing the spark plug location and the procedure for replacing them.

* Use an online repair database. Sites like AllDataDIY or Mitchell1 (subscription required) offer detailed information including diagrams.

* Search online for "[your engine size] Chevy van spark plug location". This might yield helpful images or forum posts.

Without knowing the engine size, it's impossible to give you a precise location. They're generally on top of the engine, but their exact arrangement varies significantly between engine types.
