Performance Oil Change Service

Performance Oil Change Service $29.95 in addition to engine oil services

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.

BG logoSolution: A BG 9800 tool safely and effectively cleans and removes oxidized particles and fluid contamination left behind from previous oil changes. Install new oil and filter along with BG MOA® to fortify new oil for optimum performance and engine protection. The result will be improved engine compression, increased power and increased fuel economy.

Cooling System Flush

Cooling System Flush Service From $206.45

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.

BG logoResult:

    • 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

Automatic Transmission Service From $395.95

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.

BG logoResult:

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

Power Steering System Flush

Power Steering Service From $174.50

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.

BG logoResult: (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

Brake System Fluid Flush

From $129.95

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.

BG logoResult: (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

Menu | Top

Climate Control Service

From $89.95

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

FREE with any above services

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.

BG logoResult: (Removes corrosion from battery acid and cleans battery terminals)

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

Menu | Top

Drive Line Service

Call for estimated price

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.

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

Wheel Alignment

Better Gas Mileage, Better Handling...

Precision wheel alignment can improve your car or SUV's gas mileage as well as give you better performance and road handling in town or on the highway. Wheel vibration and steering pulling can not only damage your tires, they force your engine to work much harder than it should. Keeping your cars and SUVs properly aligned is one of the best ways to save money at the pump and the tire store.

If you are a local San Francisco automobile owner, visit International Sport Motors today for a wheel alignment assessment with our new Hunter alignment technology. This state-of-the-art alignment system can calculate wheel alignment on most cars and SUVs within two minutes.

Make sure your car is properly aligned and in tip-top running condition with the wheel alignment and mechanic pros at ISM!

Wheel Alignment Warning Signs

  • Driving vibration in the steering column or beneath the seats.

  • Unusual tire wear.

  • Tire tread is worn down on one site of the tire.

  • Balding around the edges of the tires.

  • Your steering wheel feels loose or unstable.

  • Your car or SUV pulls to the side while driving.

  • Your car turns when driving on a straight and flat road or highway.

A vehicle with a tire and/or wheel that is out of balance will often create vibrations that can become increasingly worse at higher vehicle speeds. The exact speed when the problem becomes most apparent can vary from vehicle to vehicle depending on the weight and size of the vehicle.

The size of the problem and the sensitivity of the vehicles suspension and steering systems can also play a role. Commonly, when there is a problem, humming and vibrations start around 40-50 MPH and grow with increasing speed.

Computerized Wheel Alignment

International Spot Motors has the right equipment to restore your car or SUV to perfect factory specifications. All of our vehicle alignment mechanics perform complete inspections on your suspension and steering system, take precision computerized measurements, and make exact factory specified adjustments to return your wheel alignment to flawless, factory condition.

When is a good time to check my wheel alignment?

  • When you buy new tires you'll want to make sure you have good wheel alignment to get the longest life out of your tire purchase.

  • After an accident, fender bender or major collision.

  • If the car bottoms out severely or is jarred by road damage or large potholes.

  • After having work done on any of your vehicles steering or suspension systems.
