$99.99 Full Synthetic Oil Change

STARTING AT $99.99. Motor oil and the parts needed for your oil change vary in price from vehicle to vehicle. Please call for an exact price quote for your vehicle make and model. Our technicians are trained to service just about every make and model vehicle, from engine repair to oil changes.

$190.00 Engine Light Diagnostic

Our technicians are highly skilled and experienced with just about every vehicle make and model. If your check engine light is on, you can bring it to our shop and we’ll diagnose what’s wrong with it. Any authorized diagnostic will be applied toward the cost of your repair, a $190.00 value.

Blown Head Gasket

The blown head gasket is a notorious issue on 1990s-era Toyota Supra turbo models. This failure allows engine oil and coolant to mix together, causing serious drivability and performance problems.

At our shop, we verify a blown Supra head gasket using a chemical test kit to check for exhaust gases in the cooling system. Once diagnosed, we remove the damaged gasket and resurface the cylinder head and engine block to restore a smooth sealing surface. Our techs always install a multi-layer steel gasket to prevent future failures. By proactively addressing a failing head gasket, we can prevent catastrophic engine damage down the road.

Oxygen Sensor Failure

The oxygen sensor is a key emissions component that regulates the air-fuel mixture on all Toyota Supras. When this sensor fails, it causes poor engine performance, decreased fuel economy, and check engine light illumination.

Using a professional-grade scan tool, our techs retrieve diagnostic trouble codes that point to a bad oxygen sensor on your Supra. We then test the sensor’s voltage response and heating elements to confirm it is no longer functioning properly. For optimal results, we replace faulty oxygen sensors with new Toyota OEM components designed specifically for your vehicle. Properly functioning oxygen sensors keep your engine running efficiently.

Turbocharger Breakdown

The twin-turbo 2JZ engine found on fourth-generation Supras is prone to turbo failures like wastegate sticking, oil leaks past seals, and compressor wheel damage. These turbocharger problems lead to increased emissions, lack of power, and visible blue smoke from the tailpipes.

At our shop, we visually inspect Supra turbochargers for oil seepage or cracked housing components. Using a boost leak tester, we check for air leaks causing boost pressure loss. For rebuildable turbo damage, we can replace the failed internal parts. However, we generally recommend installing new Garrett or Precision turbochargers on high-mileage Supras to prevent reoccurrence. Properly operating turbochargers are critical for delivering that incredible 2JZ acceleration Supra owners expect.

Power Steering Fluid Leaks

Power steering fluid leaks are another common issue on all generations of the Toyota Supra. The power steering pump, pressure lines, return hoses, and rack and pinion gear can each develop leaks over time. Identifying the exact leak source is critical for proper repairs.

Our techs thoroughly clean the Supra’s steering components before performing a visual inspection and using UV dye to detect the leak location. We then replace only the failed component, rather than the entire system. For example, a leaking power steering pressure hose would be replaced with a new hose. With the leak repaired, we flush the system and refill it with fresh fluid for optimized steering performance.

Valve Cover Gasket Oil Leak

On the straight-six Toyota Supra engine, the valve cover gasket seals the cylinder head and prevents oil from leaking externally. When this gasket deteriorates, it leads to external oil leaks down the sides of the engine, oil burning smells, and reduced oil levels.

To accurately diagnose a Supra valve cover gasket leak, our technicians use a degreaser and UV dye to identify the source. We then remove the valve cover, scrap the old gasket material, and seal the new Toyota gasket into place using gasket sealant. With the fresh gasket installed and the mating surfaces cleaned, the bothersome valve cover oil leak is eliminated for worry-free driving.

Worn Suspension Bushings

The rubber suspension bushings on Toyota Supras wear out over time. This leads to loose, sloppy handling and uneven tire wear. Replacing worn bushings restores factory-precise suspension geometries for improved grip and ride quality.

At our shop, we place the Supra on a vehicle lift and inspect the condition of all the suspension bushings. When worn bushings are found, we press out the damaged rubber pieces and install new durable polyurethane bushings in their place. With the fresh bushings installed, we perform a professional four-wheel alignment to factory specifications. This eliminates tire wear issues and enhances Supra handling performance.

Ignition Coil and Spark Plug Failure

As a key component of the Supra’s ignition system, faulty ignition coils cause engine misfires, poor performance, and fuel efficiency drops. Similarly, worn spark plugs reduce power and can lead to difficult hot or cold starting. Both ignition coils and spark plugs degrade over time and mileage.

Using a diagnostic scan tool, our technicians look for trouble codes indicating ignition system faults. We then test coil primary and secondary resistance values against factory specifications to identify failures. For spark plug issues, we check the wear of the electrodes and insulator condition visually. As needed, we replace the worn coils and spark plugs, restoring smooth engine performance and maximum horsepower.

From turbocharger breakdowns to suspension bushing wear, Toyota Supras are prone to several common mechanical issues. But by gaining an understanding of these repairs, owners can make maintenance decisions that enhance the longevity of their vehicles.

Here at Fremont Foreign Auto, our knowledgeable technicians have the specialized tools and expertise to accurately diagnose and fix any Toyota Supra issue. Whether you reside nearby or make the trip from surrounding cities, we guarantee high-quality workmanship and fair pricing.
