For a car that has run 30,000 kilometers, both basic and advanced maintenance are required. Basic maintenance includes: Changing the engine oil, oil filter, air filter, cabin air filter, and fuel filter. Advanced maintenance includes: changing the brake fluid, power steering fluid, and coolant. The replacement intervals for each item are as follows: Cabin air filter: 10,000 kilometers. Fuel filter (internal/external): Internal: 40,000-60,000 kilometers; External: 20,000 kilometers. Brake fluid: Within 2 years or 40,000 kilometers. Power steering fluid: Approximately 2 years or 30,000 kilometers. Coolant: 2 years.

After running 30,000 kilometers, it's time to give the car a thorough maintenance. Changing the engine oil is a must, and the oil filter should be replaced along with it. The air filter is probably clogged with dust, affecting the engine's breathing. I usually check the air filter box myself to see how dirty it is. The brake pads need to be measured by a mechanic for thickness; if they're worn down to just 3 millimeters, they should be replaced immediately. The tires should be checked for uneven wear, and a four-wheel alignment should be done to prevent the car from pulling to one side. The chassis rubber bushings and suspension ball joints should also be carefully inspected for cracks or aging. If the spark plugs have never been replaced, now is the time to get a new set to avoid affecting ignition performance. The coolant and brake fluid should be replaced after this long, especially since the cooling system must not fail when using the air conditioning in summer. After all these are done, you can drive with peace of mind.

Does idling with the AC on harm a diesel vehicle?

Idling with the AC on can harm your vehicle. 1. Reason: It is not recommended to keep the engine idling with the AC on for extended periods, as this not only wears down the engine but also leads to deteriorating air quality inside the cabin when the AC is set to recirculate mode, potentially producing harmful gases. 2. Justification: The power consumed by the AC accounts for only a small portion of the engine's idle energy output. However, when idling with the AC on, the engine must not only power the AC compressor but also maintain the operation of the power steering and brake booster pumps, wasting energy. If the engine detects excessive pressure, it may automatically increase fuel injection, leading to higher fuel consumption and increased carbon buildup in the engine.

How to Determine if a Truck Fan Clutch is Faulty?

Truck fan clutch failure can be determined by checking for oil leaks and observing changes in water temperature during winter or summer driving. Specific details are as follows: 1. Water temperature changes: A faulty fan clutch can cause excessive or insufficient airflow. Excessive airflow prevents the engine temperature from rising promptly, while insufficient airflow leads to engine overheating and operational failure. 2. When the fan clutch malfunctions: In this scenario, the engine may fail. The main shaft of the loosened nut locking disc inserts into the pin hole, fixing the fan and drive shaft without using the fan clutch, forcing the fan to rotate. When there's an opportunity to repair the fan clutch, the automatic clutch function should be restored.
