Challenger Maintenance

A spark plug is a device for delivering electric current from an ignition system to the cylinders of an engine to ignite a compressed fuel/air mixture. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a porcelain insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil, coil pack or magneto. The plug has an electrode than is well insulated from heat and cross...

If your Challenger has a compact spare tire, it can be negatively impacted by lots of conditions, from heat, exposure to UV rays, and even time. It is recommended that you check your spare every time you have your tires rotated, approximately every 6,000-8,000 miles. When inspecting your spare, check for: proper air pressure signs of aging damage excessive wear Spare tires age like any other tire. Even if your spare tire never sees any use, it is still affected by the passage of time. As...

Maintaining tire pressure may seem like a low priority, but keeping the correct air pressure in your tires is an important part of vehicle maintenance. It helps in the following areas: · Safety · Optimizing tire performance · Improving fuel economy · Improving handling and performance while driving · Extending treadwear · Maintaining steering response · Improving cornering ability and stability · Improving steering precision Your tires are properly inflated when they match the...

The switch is in headlight mode(not auto) and the dash display also changes.

When you pull into a gas station, you usually presented with four options: regular, plus, premium and ultra premium. But, have you ever wondered what those numbers- 87, 89, 91 and 93 mean? Octane is the measure of how much compression a fuel can withstand before igniting. The higher the octane rating, the less likely the fuel is going to pre-ignite (i.e., explode unexpectedly) at higher pressures and damage your engine. That’s why performance cars with higher compression engines require...
