1986 GMC C1500 Suburban Engine Tune-Up Q&A

  • Will it hurt my GMC C1500 Suburban to drive with old spark plugs? Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on GMC’s recommendations.
  • What should I do if I see leaks under my C1500 Suburban? Don't ignore puddles of fluid under your GMC C1500 Suburban. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • What do hard starts and stops do to my C1500 Suburban engine? Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.
