Where is the oil gauge sensor on a 1984 gmc with 350 engine?

The oil pressure sensor on a 1984 GMC with a 350 engine is typically located on the driver's side of the engine block, near the oil filter. However, the exact location can vary slightly depending on the specific engine configuration. It's a small sensor with one or two wires connected to it. It's often a threaded fitting that screws into the engine block.

To be certain, you should:

* Consult a repair manual: A Haynes or Chilton repair manual specific to your 1984 GMC with a 350 engine will show you a diagram and pinpoint the location.

* Look closely around the oil filter: This is the most common area.

* Use a visual inspection: With the engine cool, carefully examine the engine block near the oil filter. Look for a small sensor with wires connected to it.

Caution: Be careful when working around hot engine parts. Allow the engine to cool completely before attempting any inspection or repair.
