What happens if my GMC Sierra 3500 HD spark plugs fail?

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 do I do if I see a pool of liquid under my GMC Sierra 3500 HD?

What do hard starts and stops do to my Sierra 3500 HD engine?
