MAINTENANCE IS THE KEY TO YOUR CARS' DEPENDABILITY

Brake Flush

• The most important flush is the Brake Flush because it directly effects saftey. Moisture contamination is the reason brake fluid becomes old. Glycol-based brake fluids absorb moisture that gets into system past seals, via microscopic pores in brake hoses and air introduced into the system. As a system heats and cools, condensation forming within can drastically reduce the fluid's boiling point temperature. When the fluids boil, durning severe brake usage, vapor lock can occur that greatly reduces braking efficiency.In the worst case, compressible vapor pockets replace brake fluid so when you hit the brakes, the brake pedal goes to the floor. Moisture can also cause rust and corrosion, which can pit master cylinders, steel brake-lines, wheel cylinders, pistons and other critical parts.

Transmission Flush

• Nearly 90% of transk\misssion failure is due to overheating and fluid contamination according to the Automotic Transmission Rebuilders Association. Just like the oil in your car's engine, automatic transmission fluid (ATF)suffers from heat, friction and electrochemical degradation. Once these processes begin, your transmission's vital parts begin to clog with sludge and varnish deposits. Unlike your car's engine, where all the oil can be dranied out, most of the transmission fluid doesn't drain intop the transmission pan. Instead, it stays in the torque converter, valve body and transmission cooler lines, making a complete fluid drain impossible. In fact, the typical transmission service only replaces 25% of the transmission fluid, leaving behind 75% contaminated fluid to mix with the new ATF. According To ATF manufacture, the addition of new fluid to contaminated fluid can actually cause sludge and varnish deposits to clog filters and restrict the flow of transmissionfluid. This can result ina serious malfunction, or even complete failure of an automatic transmission.
• Now there is an option, Virginia Automotive Service has purchased a Transmission Fluid Flush Machine to provide you with the latest service procedure that saftely removes varnishes and sludge deposits and cleans all the internal components, including the transmission cooler, valve body and torque converter. This service is also the best way to remove wear metals that are slowly grinding away your transmission's internal components along with the old contaminated ATF and conditioner that revitalize the seals and O-rings in the transmission.  
• According to Manufacture's Recommendations this service should be performed every 30,000 miles.

Fuel Injection Flush

• Since your car was new, varnishes and carbon deposits have been forming in you vehicle's fuel system on the inake and in the combustion areas. Thesr buildups an rob your car of performance. Some of the systoms related to carbon buildup are engine pinging, hesitation, poor accerlation, lack of power, repeated stalling when cold, poor performances when cold, rough idle, and poor fuel economy. These buildups left untreated may lead to total engine repairs.
• According to Manufacture's Recommendations this service should be performed every 30,000 miles.

Power Steering Flush

• Helps avoid hard erratic steering and keeps you in control.

Coolant System Flush

• Whenever a fluid is in contact with metal, eletrochemical degradation takes place, which results in a higher than normal level Ph level if acid is present.This higher acid level if left unchanged can result in very costly repairs. As a result, it is recommended that you flush your cooling system and most importantly Ph balance your antifreeze, at least once a year. This will help reduce the acid level and extend the life of your radiator, heater core, water pump, head gaskets, freeze plugs, radiator and heater hoses.You have probaly heard mant times that your cooling system should bre procted to -35 degrees. You may wonder why, when it becomes very cold. This is because water is the best conductor of heat. It's molecules are spaced far apart and heat can move into the water very easily. The problem with water is that it is corrosive when in contact with metal and can freeze. Ethylene gycol silicone based anitfreeze is added to water to protect the metal keeping the water from freezing, and lubracate the moving parts in the cooling system, such as the water pump, and thermostat. If you use 100% antifreeze, the engine may overheat in kit weather, with or without your air conditioner on. The reason is antifreeze molecules are packed tightly and are unable to move the heat from the engine as efficiently as water. The condenser for your car's air conditioner operates much hotter than the radiator; that is why it is placed in front of the radiator. The radiator dissipates the heatfrom your car's air conditioner and makes this coolant even hotter.
• With today's new computer controlled engines, proper coolant temperatures is most important. The temperature sensor tells the computer, along with other sensors, how to adjust the fuel mixture and ignition timing. This may affect engine performance and efficiency. For the best heat removal and metal protection,50% water and 50% antifreeze is desired. The proper mix is determned by checking the coolant level; -35 degrees equals 50/50. The problem comes when the pH of water is 7.0 to 7.2 and antifreeze pH is 10.5 out of the container.A 50/50 mix of water and antifreeze would have a pH factor of 8.75 This level is too acidic for today's cooling systems. The recommened pH level should be between 9.8 and 10.5. This level greatly reduces the acid content that, together with the electrochemical reaction the acid content that, together with electochemical reaction of dissimilar materials, causes electrochemical degradation.
• To correct this condition, we power flush your cooling system by continously forcing the coolant through a flitering system that will remove all contaminates. Our machine will remove down to one micron. Once this is done, antifreeze is added to the system to bring it to the desired -35 degrees throughout the system. We then add a pH concentrate while still circulating the coolant  to evenly reach a pH of 10.5 throughout the system. We stop at 10.5pH because over time, as the hot coolant flows the system, it will slowly become more acidic as descibed above. We also pressure test the system for leaks, clean the recovery bottle and test radiator cap to confirm that it holds the proper pressure.
• As we said before it is recommened that you flush your cooling system every year.
