However, be aware that exact placement can vary slightly depending on the specific engine configuration. To be absolutely sure, consult a repair manual specific to your 1997 Pontiac Sunfire 2.2L. A Haynes or Chilton manual will have diagrams and detailed instructions. You can also use online resources like auto parts store websites (like AutoZone or Advance Auto Parts) that provide diagrams based on your car's year, make, and model. They often have online diagrams that can help you pinpoint the location.
