AvatarByCarl Frisch

Subaru Forester 90k Service is a routine maintenance service performed on Subaru Forester vehicles at 90,000 miles. This service includes checking and replacing vital parts, such as the engine oil, oil filter, air filter, drive belts, spark plugs and other parts that may need attention. The service also includes a thorough visual inspection of the vehicle’s exterior and interior components to ensure proper operation. In some cases, additional services such as brake pad replacement or transmission fluid change may be required to maintain the vehicle in optimal condition. This service is essential for maintaining your Subaru Forester in peak performance and reliability.

Safety Check

When taking your Subaru Forester in for a 90K service, the technician will perform a safety check to ensure that all of your vehicle’s systems are functioning properly. This involves checking the brakes, suspension, steering and other important components to make sure they are in good working order. They will also inspect the tires and wheels to make sure they are inflated and aligned properly. Additionally, they may run a diagnostic test to identify any potential problems with the engine or transmission. After performing the safety check, the technician will provide you with any necessary recommendations for repairs or maintenance.

Vehicle Fluids

As part of the 90K service on your Subaru Forester, the technician will also change out all of the vehicle fluids. This includes an oil change, a coolant flush and a transmission fluid replacement. These fluids should be changed out according to your manufacturer’s recommended schedule to ensure optimal performance and prevent damage over time. During this process, the technician may also check other fluids such as power steering fluid and brake fluid, and top them off as needed.

Filter Replacements

The technician will also replace several filters during your Subaru Forester’s 90K service appointment. This includes changing out the air filter which helps keep debris out of your engine, as well as replacing the cabin air filter which helps keep dust and pollen from entering through your vents. They will also replace your fuel filter which helps clean contaminants from your fuel before it enters into your engine combustion chamber.

Spark Plug Replacement

The spark plugs on your Subaru Forester need to be replaced every 90K miles in order to ensure that they are functioning correctly and providing optimal performance from your engine. During this process, the technician will inspect each spark plug for signs of wear and tear before replacing them with new ones that have been specifically designed for use in Subaru vehicles.

Brake System Checkup

The last step of a 90K service on a Subaru Forester is performing an inspection of its brake system components. The technician will check both calipers and rotors for wear or damage that could inhibit proper braking performance. They may also recommend replacing these components if necessary depending on their condition. Additionally, they may perform a brake fluid exchange which helps keep moisture levels low in order to reduce corrosion within the brake system components over time.

Tire Rotation and Wheel Alignment

Making sure that your Subaru Forester’s tires are properly aligned and rotated is an important part of the 90k service. Having your tires properly aligned helps to improve fuel efficiency, as well as reduce wear on the tires. The wheel alignment should be inspected and adjusted every 10,000 miles to ensure proper alignment. Tire rotation is an essential part of preventive maintenance as it helps to even out the wear on all four tires. This helps ensure that all four tires have an equal amount of tread and provides better handling and traction. It is recommended that you have your tires rotated every 5,000-7,500 miles, depending on the type of tire you have.

HVAC System Checkup

The HVAC system in your Subaru Forester needs to be checked regularly to make sure it is functioning properly. This includes checking the air conditioner for any refrigerant leaks or low levels, as well as inspecting all heater core valves for any blockages or corrosion. Additionally, a visual inspection of all hoses and connections should be done to make sure everything is secure and free from damage or wear. This will help improve the efficiency of your HVAC system and keep it running smoothly for longer periods of time.

Electrical System Checkup

The electrical system in your Subaru Forester should be checked regularly as part of a 90k service to ensure that it is functioning properly. This includes testing the battery for any signs of corrosion or damage, as well as cleaning any terminals if needed. Additionally, the alternator should be tested for any problems such as low voltage output or excessive current draw which can cause premature failure of other electrical components within the vehicle. Taking care of these small issues can save you time and money down the line by helping prevent major electrical issues from occurring in the future.

Drivetrain Inspection

The drivetrain in your Subaru Forester needs regular attention in order to keep it running smoothly for longer periods of time. A 90k service should include checking all axle boots and bearings for signs of wear or damage, inspecting CV joints for any signs of corrosion or deterioration, and inspecting driveshaft boots for any leaks or tears which can cause vibration when driving at higher speeds. Regular inspections can help identify potential problems before they become major costly repairs down the line which can save you both time and money in the long run.

Overall Vehicle Inspection

In addition to all other components mentioned above, a 90k service should also include an overall vehicle inspection consisting of checking brakes discs/pads/calipers/rotors/fluid levels; checking shock absorbers; inspecting steering components; checking engine belts/filters/fluid levels; inspecting exhaust systems; inspecting suspension components; checking transmission fluid levels; inspecting wheel bearings for play; testing battery charge rates; testing windshield wipers/washers/defrosters; lubricating door hinges; changing engine oil/air filter/spark plugs (if applicable); adjusting tire pressure (if necessary); checking interior lights/dome light operation; replacing wiper blades (if necessary); top off coolant level (if necessary); inspect seat belts mechanism operation (if applicable). Taking care of these small details can help prevent major issues from occurring down the line which could turn into costly repairs if not caught early enough.
