Challenger Maintenance

There has been much discussion if an oil catch can is necessary on a high performance engine. It is my opinion that the relatively modest price (usually about $100) is cheap insurance for your engine. First, let's go over what is currently happening in your engine without a catch can installed. All internal combustion engines that run off gasoline are 4-stroke engines. This means that the piston has to go up and down a total of 4 times to complete a cycle. The piston first goes down with...

One of the best things that you can do for your Hemi engine is to change your oil at the factory recommended intervals, or sooner, and to use a high quality oil filter. Clean motor oil is important because if the oil were left unfiltered for a period of time, it could become saturated with tiny, hard particles that can wear surfaces in your engine. This dirty oil can wear the oil pump’s machined components and damage the bearing surfaces in the engine. Here is how an oil filter works. The...

Synthetic oil is better than conventional oil when it comes to its form and function. Conventional oil could never stand up to synthetic when it comes to longevity and ability to handle extremely high temperatures. That’s why you see full synthetic oils in all race cars. Conventional and synthetic oils begin in the ground. But that’s where the similarities end. Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules. This process not only...

WD-40 is truly a versatile product. It was created in 1953, by three technicians, at the San Diego Rocket Chemical Company who were searching for a rust preventative solvent and degreaser to protect missile parts. Its name comes from the project that was to find a “water displacement” compound. They were successful with the 40th formulation, thus Water Displacement #40, or WD-40 was born. Initially it was purchased, in bulk, by the Corvair Company to protect its Atlas missile parts....

Alternators were first introduced as standard equipment on a production car by Chrysler for the Valiant model in 1960- several years ahead of Ford and General Motors. They replaced direct current generators (dynamos) because they were lighter, cheaper, more rugged and could provide a useful charge at idle speed. The present-day charging system hasn't changed much since 1960. It consists of the alternator, regulator (which is usually mounted inside the alternator) and the interconnecting...

My experience arresting the back quarter panel rust issue caused by the foam insulation.

Top Tier is a performance standard for gasoline, backed by major automakers. Since the 1990s, the Environmental Protection Agency has required a minimum level of detergent for all gas sold in the United States. But some automakers say the EPA standards are not good enough. To be considered Top Tier, the gasoline must have a higher concentration of detergent added to it. Some brands use the minimum level of detergent additives required by the EPA, others add proprietary formulations of...

Brembo brakes can be found on high-end European brands, such as Lamborghini, Ferrari, Porsche and Mercedes-Benz, as well as Dodge high-performance vehicles. It is worthwhile to learn how Brembo became the leader in the design, development and production of original equipment, racing and aftermarket brake components and systems. The company was established in 1961 in Bergamo, Italy. Responding to its growing international success and demand for its products, it established Brembo North...

The information found on a tire sidewall contains important information about the tire size, load capacity, weather ratings, and even government ratings for treadwear, traction and temperature. For illustration purposes, we will look at a 245/45ZR-20 tire (typical size for a Challenger R/T). Section Width The 245 indicates that the tire is 245 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified...

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...

The average life of a tire is determined by the conditions a tire is exposed to throughout its life - not measured in calendar years. Temperature changes, sun exposure, storage conditions, usage, and maintenance schedules all contribute to the rate at which a tire ages. It is impossible to determine a tire’s exact life expectancy, because there is no way to account for the level of influence any one of these factors may have on a tire. However, you can defer to the vehicle and tire...

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

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...
