Removes carbon and deposits from injectors, valves, and combustion chambers. Carbon deposits are the result of additives used in modern gasolines to keep them stable and burnable. These necessary chemicals leach out and form substantial collections of carbon. Motorvac or carbon depletion services are recommended for emissions failures, engine pinging problems, rough idle problems, hard starting, hesitation problems and as general preventive maintenance. Failure to perform this service could lead to failed emissions, various performance concerns, lowered fuel economy, engine noises and sometimes — engine damage.
Removes scale and contamination from inside the radiator and engine and maintains the proper coolant pH. Coolant pH is continually dropping and the lower the pH the more acidic and corrosive the coolant becomes. Coolant should be changed at two years or twenty four thousand miles on most vehicles. Failure to flush coolant can lead to: water pump failure, radiator failure, shortened hose life, failed head gaskets and many other costly failures.
Softens and removes normal contamination from the inside of the transmission. It is especially helpful in removing dirt that collects inside the torque converter. Because the torque converter spins at a high rate of speed, dirt suspended in the transmission fluid is spun outward inside the converter and builds up on its inner surfaces. Dirt continues to build until it reaches a sufficient thickness to begin flaking off in chunks. The chunks of dirt restrict the flow of fluid through very small passages inside the transmission. Reduced fluid flow causes the transmission to overheat leading to rapid wear of automatic transmission clutches and premature transmission failure. Routine transmission flushing can double or triple the life of your automatic transmission. It is one of the most cost beneficial services you can perform.
A relatively new process that helps prevent the failure of seals and gaskets inside the power steering pump and steering rack. In the past, power steering fluid was not a concern and typically lasted the life of the vehicle. Today, power steering fluid deteriorates much sooner due to significantly higher operating temperatures and pressures. Fluid deterioration can be credited with an estimated 300% increase in power steering repairs over the past fifteen years. Power steering flushing prevents most expensive power steering failures.
Brake fluid is hygroscopic which means it attracts and absorbs water. This is a natural occurrence in all brake systems. Contrary to a popular myth, there is no such thing as a sealed brake system. Because brake fluid attracts water like a magnet attracts metal, moisture can even be drawn into the fluid through the pores of rubber brake system components. Moisture in the brake system combines with available oxygen causing oxidation of brake hydraulic parts. Some cheap, some staggeringly expensive!
No matter how meticulous you are about oil changes there are areas inside every engine where oil doesn’t circulate well. The oil sits in depressions in metal castings of the engine where it slowly becomes thick and gooey from heat. Over time this forms chunks of sludge that move about inside the engine. As these chunks find their way to the oil pan they’re sucked into the oil pump pickup screen where they eventually restrict the amount of oil that can circulate for lubrication. Net result — shortened engine life.
Coolant, transmission fluid, power steering fluid, and brake fluid should be replaced before they change color. When a fluid changes color it’s causing damage to the system it is supposed to protect. Example: coolant changes color because of rust. (Rust n. dissolved engine.)
