Maintenance items for a car at 30,000 kilometers include: 1. Oil change; 2. Oil filter replacement; 3. Air filter replacement; 4. Fuel filter replacement; 5. Throttle body cleaning; 6. Spark plug replacement, etc. Among these, oil change and oil filter replacement are mandatory items because engine oil deteriorates significantly under the high-temperature and high-pressure conditions inside the engine, leading to reduced performance over time and failing to protect the engine effectively. The oil filter prevents impurities from mixing with the oil and avoids the formation of sludge and clogging in the oil passages due to oxidation. Therefore, both the oil and oil filter should be replaced simultaneously.

What is the actual fuel consumption of the Malibu?

The fuel consumption per 100 kilometers is 6.8 liters, which translates to 0.068 liters per kilometer. The Chevrolet Malibu is equipped with a 1.5T engine paired with a 6-speed automatic transmission, delivering a maximum power of 125kW (170PS). The maximum rated power (Kw/rpm) is 125/5600, with a displacement (ml) of 1490 and a maximum torque (Nm/rpm) of 250.3/2000-4000. Below is relevant information: Fuel consumption: Fuel consumption generally refers to constant-speed fuel consumption. Constant-speed fuel consumption is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. Product features: In terms of appearance, the Malibu integrates the headlights and the grille, with the headlights adopting a combined high/low beam structure and xenon light sources. In terms of power, the Malibu is powered by a 1.5T engine with a maximum power of 125kW (170PS), mated to a 6-speed automatic transmission, achieving a minimum combined fuel consumption of 6.8L per 100 kilometers under comprehensive conditions.

What Causes the Engine Warning Light to Illuminate with Engine Shaking and Stalling?

When the engine warning light illuminates accompanied by vehicle shaking, the cause is typically poor combustion of the air-fuel mixture. Incomplete combustion leads to engine carbon buildup, which is the primary reason for vehicle shaking. Additionally, when the oxygen sensor detects this poor combustion and reports it to the ECU, the warning light activates as an alert. This explains why the engine warning light and vehicle shaking often occur simultaneously. Several issues can cause poor air-fuel mixture combustion, including faulty spark plugs, defective ignition coils, malfunctioning fuel pumps, or clogged fuel lines. If the engine warning light illuminates, follow these steps: First, check if the engine is operating normally—look for symptoms like shaking, black smoke emissions, or difficulty starting. If present, avoid restarting the engine. Importantly, never restart the engine if the red warning light is on. If the engine runs normally and the vehicle is drivable, proceed to a service station promptly for diagnosis. Technicians can easily retrieve trouble codes using a portable diagnostic tool to pinpoint and address the issue. For normally functioning engines, owners may also try gently reseating all wiring harness connectors (as loose connections could be the culprit) or repeatedly turning the ignition key to the ON position to see if the warning resets.

How to Adjust Brake Pulling to the Left?

Adjust and repair the braking system. During testing, if the brake marks are inconsistent, the brake pulling is caused by the braking system. Adjust and repair the steering system. If the brake marks are basically consistent but the vehicle still pulls, check whether the ball joints in the steering system are loose. Check whether the front axle suspension is loose. Focus on inspecting the shackle and spring pins, the height of the left and right springs, and whether the spring tension is consistent.

What Causes Abnormal Noise During Gear Shifting in the Transmission?

Here are the main reasons for abnormal noise during gear shifting in the transmission: 1. Transmission bearings often operate under high-speed and heavy-load conditions, enduring significant alternating loads. As a result, the rolling balls or cylindrical rollers and raceways of the bearings may experience wear, spots, fatigue spalling, or burning, leading to increased axial and radial clearance, which causes impact noise. 2. During gear meshing transmission, sliding friction exists from the tooth top to the tooth root, making wear inevitable. Due to gear wear, the meshing clearance increases, resulting in impact noise during vehicle operations such as starting or shifting gears. 3. After bearing wear causes looseness, shaft deformation or housing deformation alters the center distance between meshing gears and causes misalignment of axes; wear in the sliding keyways on the shaft and internal spline grooves of sliding gears; loose fastening bolts in the control mechanism and wear or deformation of the shift fork can lead to gear displacement. 4. Improper driver operation, such as aggressive starting or poor hand-foot coordination during gear shifting, can cause significant impact loads in the transmission, leading to broken or shattered gear teeth and abnormal noise.
