When should Mercury Cougar spark plugs be replaced?

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 Mercury Cougar mean?

Are hard starts and stops bad for my Mercury Cougar engine?
