Questions About 1991 GMC S15 Jimmy Engine Tune-Ups

  • When should GMC S15 Jimmy spark plugs be replaced? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What does a puddle underneath my GMC S15 Jimmy mean? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • Are some driving habits better for my GMC S15 Jimmy engine than others? You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.
