What are the major maintenance items at 90,000 kilometers?

[Donna]

Major maintenance items at 90,000 kilometers include: 1. Replace the air filter; 2. Replace the oil filter; 3. Clean the fuel system, fuel injectors, and throttle body; 4. Clean the intake manifold and catalytic converter; 5. Replace the timing belt, tensioner pulley, and tensioner; 6. Clean the interior and exterior of the vehicle, as well as the engine and chassis. Car maintenance, also known as vehicle servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. The purpose is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent failures, and extend the service life. Minor maintenance generally refers to the routine maintenance items performed at the manufacturer-specified time or mileage to ensure vehicle performance. Major maintenance is based on minor maintenance, and these two types of maintenance are usually performed alternately.

When my car reaches 90,000 kilometers, I pay special attention to several major maintenance items. First, the engine oil and oil filter must be replaced, as old oil can thicken and affect engine performance; the air filter and cabin air filter should also be renewed to ensure smooth airflow. Second, inspect the braking system, including the wear level of the brake pads and whether the brake fluid has deteriorated, as this is crucial for stopping safety. Third, rotate the tires to balance wear and extend their lifespan; also check the spark plugs—if they were replaced recently, this step can be skipped, but the viscosity of the transmission fluid (whether manual or automatic) should be tested. Fourth, check the coolant level and color to prevent engine overheating; the timing belt is a critical item at 90,000 kilometers—inspect it for cracks to avoid a potential breakdown leading to major repairs. Finally, take a quick look at the suspension shock absorbers for any oil leaks to ensure driving stability. These maintenance tasks help prevent sudden failures, saving money and providing peace of mind.

I've always enjoyed doing my own car maintenance. At 90,000 kilometers, I usually start by changing the engine oil and oil filter - it's an easy job with simple tools. I order new air filters online and replace them myself, which takes just minutes. Don't neglect the cabin air filter either, as it affects driving comfort. Then I check the brake system: top up with new fluid if levels are low, but take it to a professional shop if the pads and rotors are severely worn. I rotate the tires myself, swapping front and rear to reduce uneven wear. If the spark plugs haven't been changed before, I buy a tool set and replace them myself to save money. Transmission fluid can be manually checked for color and cloudiness - if it looks bad, I take it to a shop for a complete change. Topping up coolant with fresh fluid is convenient. This DIY approach helps control costs while keeping me informed about my car's condition.

As a budget-conscious car owner, I believe the 90,000 km major service should be carefully planned. The core tasks are changing the engine oil and oil filter - these are affordable but essential. Air and cabin filters are inexpensive to replace and help prolong the AC system's lifespan. Never skimp on brake inspections - safety comes first when checking pads, rotors and fluid. Rotate tires if worn to save costs and avoid premature replacement. If spark plugs are still in good condition, their replacement can be postponed. For transmission fluid, first test viscosity before deciding on replacement. Simply top up coolant rather than doing a full flush. Skip non-essential services like electrical system checks - focus your budget on critical safety and reliability items.
