Where is the oil pressure switch located on a 1998 Chevy Blazer?

The oil pressure switch on a 1998 Chevy Blazer 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 engine (4.3L V6 or 5.7L V8).

To be certain, you'll need to:

1. Consult your owner's manual: This is the best resource for the precise location.

2. Look at a repair manual or online diagrams: A Haynes or Chilton manual (or a website with repair diagrams specific to your year and engine) will show a detailed engine diagram pinpointing the switch's location. Search online for "[Your engine size] 1998 Chevy Blazer oil pressure switch location."

3. Visually inspect the engine: Once you've got a general idea from the manual or diagrams, locate the oil filter. The oil pressure switch is often near it, on the block itself. It's usually a small, cylindrical switch with one or two wires connected.

Caution: Be careful when working around hot engine components. Allow the engine to cool completely before attempting to locate or replace the switch.
