Authorized Jasper Dealer
Give Your Vehicle a New Lease on Life with JASPER. That big oil slick in your driveway or those strange noises from under your hood don't have to mean you'll be saddled with a new car payment soon. Instead, your trusted installer at High-Tech Auto and Truck Center can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call High-Tech Auto and Truck Center at 703-968-6648 to schedule an appointment. Proudly remanufactured in the U.S.A.

Cylinder Block
A cylinder block is the powerhouse for the motor vehicle. The solid cast car part houses the cylinders and their components (gaskets, valves, and seals) inside a lubricated and cooled crankcase. Since it is one of the most important parts of your car, the block is designed to be extremely strong and sturdy. Although strong and sturdy, the block is susceptible to failure resulting in a vehicle that won't start. Cracked blocks, porous blocks, core plug, or freeze plug failure are some of the problems facing cylinder blocks. Call 703-968-6648 to talk to the mechanics of High-Tech Auto and Truck Center about your cylinder block problems.

Cylinder Head
A cylinder head is the closed end of a cylinder (located in a car's engine block). It sits above the cylinder block, closing the top of the cylinder and forming the combustion chamber. The cylinder head coordinates airflow in and out of the engine. Since the cylinder head's chief function is to seal the cylinders properly, insufficient compression results in the car being difficult to drive. To have your cylinder head checked and repaired, talk to High-Tech Auto and Truck Center's cylinder head repair specialists today.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:

  • Changing the oil & filter
  • Changing the air filter
  • Changing the fuel filter
  • Bleeding the fuel system
  • Draining the water separators
  • Refilling the urea injection system

You can count on the experts at High-Tech Auto and Truck Center to help your diesel engine last a long time.

Engine Maintenance
Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car engines aren't built to last forever. However, you can increase the engine's lifespan by performing regular preventive maintenance. The easiest way to maintain peak performance and fuel economy is to provide regular engine maintenance for your vehicle. To have your engine maintained by experts, visit High-Tech Auto and Truck Center.

When your vehicle shows any sign of trouble, bring it to High-Tech Auto and Truck Center for full-service engine repair in Chantilly, VA. From diagnostic check engine light repair to precision engine part repair, our expert auto mechanics are ready to help you.

Engine Replacement
The engine converts energy into useful mechanical motion. This amazing machine is what keeps your vehicle moving. Although generally reliable, a car engine is susceptible to damage and breakdown. When this happens, do not sit and stress over it. Take action. Take the vehicle to a mechanic for an engine replacement. Bring it to High-Tech Auto and Truck Center. Visit us at 4007 Westfax Dr
Suite D for quality engine replacement services.

Timing Belt
A timing belt is a part of your car's internal combustion engine. The belt synchronizes the camshaft and the crankshaft rotation so that the engine valves open and close at the correct timings. Also, the belt prevents the piston from striking the valves in an interference engine. A timing belt is a rubber belt that usually features teeth on the inside surface, while a timing chain is a metal roller chain. Most cars we drive now have timing belts instead of timing chains and gears. Although different manufacturers have their recommended mileage, you need to have your car's timing belt checked regularly. To have it checked by experts, contact High-Tech Auto and Truck Center today.

Transmission Flush
Although most manufacturers recommend a transmission flush every 30,000 miles or every two years, some symptoms may indicate that you need a transmission flush sooner. Some of the symptoms that indicate that your car needs a transmission flush sooner are: transmission grinding or strange noises, problems shifting gears, slipping gears, surging of the car, and delay in vehicle movement. Flushing the used fluid from the transmission washes away tiny particles of dirt, clutch material, and metal shavings. For all your transmission flush needs, call 703-968-6648 or visit High-Tech Auto and Truck Center today - we are transmission experts.

Transmission Maintenance
Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car transmissions aren't built to last forever. However, you can increase the transmission's lifespan by performing regular preventive maintenance. The easiest way to maintain peak performance and fuel economy is to provide regular transmission maintenance for your vehicle. To have your transmission maintained by experts, visit High-Tech Auto and Truck Center.

Transmission Repair
Our services include transmission repair on both manual and automatic transmissions. The first step in getting you back on the road is assessing your transmission to accurately determine the source of the problem. In some cases, we are able to repair your transmission simply with adjustments, replacing external seals, or replacing accessible parts. To have this done by specialists, call 703-968-6648 to talk to the mechanics of High-Tech Auto and Truck Center today.

Transmission Replacement
In motor vehicles, the transmission usually refers to the gear box, which uses gears and gear trains to transmit speed and torque from a rotating power source to another device. You can have your car's transmission replaced with a new, rebuilt, remanufactured, repaired or used transmission. For more information contact High-Tech Auto and Truck Center in Chantilly, VA. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

Taylor & the hard working crew at High Tech 4x4 are hands down the best garage i’ve used/found in the Northern Virginia area. I have brought them all types of cars with all types of issues, and some of them needing some extensive troubleshooting. These wonderful men and women have always come through with great trouble shooting at a very reasonable price. This is very hard and rare to find anywhere in this area. I’ve been an extremely loyal customer and client of theirs for over 10+ years. I won’t take my cars anywhere else. They always keep me updated, provide me with detailed estimates that are very reasonable. They stand behind their work, and they always keep all of five of my cars on the road. They will work on anything that I bring them without any complaint or hesitation. They just recently helped me on a JDM car that was only sold in Japan. The technicians were able to troubleshoot a couple electrical and mechanical issues easily and resolved these issues even without having any service repair manuals for these cars that were only sold in Japan. Very impressed with their quality of work, the way they approach the work and their pleasant attitudes. Every time i arrive with a problem Taylor & the entire crew at high tech find a solution. You guys make a car repair look easy and I appreciate you all. They are A++++ Thanks, your lifelong customer Mark

Very attentive to my concerns. The waiting area has coffee, cold drinks, and snacks. They even adjusted my headlights and pached a hole in the roof of the cab, all at no extra charge.
