Engine Light

"Check Engine" or "Service Engine Soon" Light

What should I do when my check engine light comes on?

The “check engine” light, sometimes called the “service engine soon” light, can mean a number of things. Sometimes this light comes on and the car seems to be running perfectly. The first step towards dealing with the check engine light is to hook your car up to our computer so we can read the codes your car’s operating system has logged and get to the bottom of the problem.

Once we plug-in the diagnostic reader we will be able to assess the problem. We will look at the codes that your computer has detected. These codes could direct us to cooling or electrical problems, sensor malfunctions, engine misfires or any number of common auto repair problems. Once we diagnose the issue we will contact you with a detailed estimate and recommendation for repairs. We can also provide you with a full report along with the diagnostic codes we recover from your vehicle's computer.

Performance Oil Change Service

Problem: High engine temperatures caused by heavy stop and go driving conditions lead to thermal breakdown of engine oil. Not all of the oil is removed during a drain and fill oil change. Deposits are left behind and form sludge and varnish in the engine resulting in smoke from the exhaust and increased oil usage.

Solution: High engine temperatures caused by heavy stop and go driving conditions lead to thermal breakdown of engine oil. Not all of the oil is removed during a drain and fill oil change. Deposits are left behind and form sludge and varnish in the engine resulting in smoke from the exhaust and increased oil usage.

Cooling System Flush

Problem: Coolant is depleted of buffering ingredients and becomes extremely corrosive, literally eating holes in cooling system components. By-products of corrosion damage, as well as rust and scale, clog the passageways that conduct the water through the radiator and choke off the flow. This may result in an overheated engine that may be damaged beyond repair.

Solution: The entire cooling system is first cleaned and then all debris and worn out coolant is completely removed from the system. Then, fresh new premium coolant is added. Conditioners are also included to prevent rust and corrosion and BG Universal Cooling System Sealer is also included to prevent leaks.


  • Reduces operating temperature of the cooling system, automatic transmission & air conditioning
  • Extends the life of hoses, water pump, heater core, thermostat & radiator

Transmission Fluid Flush

Problem: After 30,000 miles, transmission fluid begins to show its age as it turns brown in color and oxidizes due to the combination of time and heat. Deposits begin to form around the transmission’s many moving parts, resulting in valves that stick and gears that slip or are sluggish and chatter as they shift.

Solution: Rather than just removing the fluid found in the bottom of the pan, the entire transmission is cleaned and replenished with the use of special equipment. The transmission and its torque converter have all of their old contaminated fluid removed while new fluid and premium conditioners are added.

One of the hardest working parts of your vehicle will shift smoothly and effortlessly for many more trouble-free miles.


  • Eliminates hard shifting, chattering & slipping
  • Reconditions seals & extends transmission life
  • Provides cooler operation

Power Steering System Flush

Problem: The power steering pump produces high pressure between 800–2000 pounds, with high heat. This leads to fluid breakdown and failure. Symptoms include groaning and whining noises, erratic steering and pump leaks.

Solution: A powerful cleaner suspends and dissolves varnish and gums in the power steering system and then all of the old fluid is replaced with new high-tech power steering fluid for both conventional sector and rack and pinion. The benefit will be a quieter-operating, longer lasting power-steering system.

Result: (Cleans gums & varnish from power steering unit, removes old oxidized fluid and replaces with new fluid and reconditions seals)

  • Alleviates steering pump squeal
  • Prevents fluid leaks & reduces wear
  • Correct hard, erratic steering
Battery Service

Brake System Fluid Flush

Problem: Brake fluid becomes oxidized and contaminated over time and use. Heat and moisture cause corrosion on parts and brake fluid failure. This causes a spongy brake pedal and shows up in discolored brake fluid.

Solution: The entire brake system is inspected for leaks, master cylinder corrosion, worn pneumatic parts, harmful varnish build-up, broken or rusted bleeder valves, worn rotors and drums and air in the brake lines. All old brake fluid is replaced with BG Heavy Duty DOT 3 or DOT 4 Brake Fluid. The result will be a longer lasting, more efficient and safer braking system.

One of the hardest working parts of your vehicle will shift smoothly and effortlessly for many more trouble-free miles.

Result: (Inspect brake system and replace old, contaminated fluid with new high temperature fluid)

  • Helps prevent hydraulic failure & brake fade
  • Avoids expensive repairs
  • Helps protect ABS components

Climate Control Service

Problem: Condensation in your vehicle’s air conditioning system promotes fungus, mold and bacterial growth that is blown into the passenger compartment. Clean out the air conditioning lines, evaporator and ventilator and then kill any bacteria mold or fungi. Then, deodorize the entire A/C system and the vehicle’s interior.

Battery Service

Battery Service

Problem: Over time corrosion accumulates on the battery posts and terminals to the degree that this build-up begins to drain power from the battery. That’s one of the reasons battery failure is the #1 culprit for calls made requesting roadside assistance.

Solution: A battery cleaner and leak detector is applied after a thorough cleaning and inspection. Anti-corrosion BG Battery Terminal Protectors are installed and the battery posts, terminals and case are sealed.

Result: (Removes corrosion from battery acid and cleans battery terminals)

  • Helps prolong battery life
  • Helps avoid unnecessary battery replacements
  • Prevents unwanted breakdowns

Drive Line Service

Problem: Heat, moisture, extreme pressure and loads cause gear oil to break down or to be contaminated, leading to lubrication failure and worn gears.

Solution: Remove and replace old worn-out lubricant from manual transmissions, front and rear differentials, trans axles, and transfer cases. Install gear oil or the additive package required for vehicle application.

Result: You'll experience smoother gear-shifting, quieter operation and extended component-life, which will reduce major repair costs due to worn gears.
