Will it hurt my Pontiac Grand Prix to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What does a puddle underneath my Pontiac Grand Prix mean?

Don't ignore puddles of fluid under your Pontiac Grand Prix. 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 Grand Prix 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.

It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*.

This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your Grand Prix can determine what kind of service it needs.
