The reasons for high engine oil temperature are as follows: High engine oil temperature may be caused by insufficient oil volume or excessively high oil level; malfunction of the oil pump, or insufficient oil pumping; excessively high cooling water temperature, blockage of the oil cooler; or blockage of the oil filter. Below is relevant information about automotive engine oil: Introduction to Engine Oil: Engine oil, also known as engine lubricating oil (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Composition of Engine Oil: Engine oil is often referred to as the 'blood' of a car. It consists of two main components: base oil and additives. The base oil is the primary component of lubricating oil, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics, making them an essential part of lubricating oil.

What Causes the Squeaking Sound When Driving on Bumpy Roads?

Regarding the causes of abnormal noises when driving on bumpy roads: 1. Lower control arm issue: The lower control arm supports the tires and has two rubber bushings. Prolonged driving and steering wheel operation can cause wear on the small ball joints and bushings, leading to excessive gaps and abnormal noises when driving on uneven roads. Replacing the control arm can directly resolve the noise issue. 2. Stabilizer bar link issue: The stabilizer bar link, commonly known as a small tie rod, helps maintain vehicle stability during driving. For example, when the left and right wheels are at different heights, the stabilizer bar generates anti-roll resistance to prevent body roll and twisting of the bar. Prolonged driving can cause excessive wear inside the small ball joints, resulting in excessive gaps and abnormal noises.

Where to Turn On the Navigation in Haval M6?

Haval M6 does not come with built-in navigation, but you can connect your smartphone to the multimedia system to enable navigation on the display. Most vehicles allow for aftermarket installation of car navigation systems, which feature GPS global satellite positioning. Simply input your destination, and the navigation system will automatically calculate the optimal route based on electronic maps. If you deviate from the route during driving, the system will recalculate the path. The Haval M6 is a compact SUV under the Haval brand, featuring an interior that continues the classic design language of the Haval family. Its 'simple and practical' winged center console perfectly complements the classic three-spoke multifunction steering wheel. The smart combination instrument panel paired with an 8-inch LCD central display ensures easy access to all functions, reflecting thoughtful human-centric design.

Is the touch-up pen useful?

The touch-up pen is useful. It can cover up some minor and shallow scratches on the surface, making them less noticeable. The effect is quite good, although it cannot achieve the same result as the original car paint, it is much better than leaving the scratches untreated. For deeper or larger scratches, or those that expose the primer, the touch-up pen cannot effectively repair them. There may be color discrepancies and a lack of gloss, resulting in less than ideal results. For the proper use of a touch-up pen, the professional method is to cover areas that do not need to be painted with tape, select the appropriate color and model of the touch-up pen that matches the car paint, shake the pen well to mix the paint inside, and then apply it evenly and smoothly to the minor scratches or imperfections on the car body. Once the paint dries, it can repair, conceal, and fill in the scratches, and it also provides some rust-proofing function.

Can maintenance be done outside of 4S shops?

Maintenance can be performed outside of 4S shops. There are no national regulations requiring maintenance to be done at 4S shops during the warranty period. However, it must be conducted at legitimate businesses that can guarantee the safety and reliability of replaced parts. This approach saves money while avoiding concerns about voiding the warranty. Additional information is as follows: 1. Automotive maintenance: Refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle upkeep. 2. Modern automotive maintenance: Primarily includes the maintenance scope of engine systems, transmission systems, air conditioning systems, cooling systems, fuel systems, power steering systems, etc. The purpose of automotive maintenance is to keep the vehicle clean and tidy, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life.

What is the 0-100km/h acceleration time of the Ford Equator?

Ford Equator's 0-100km/h acceleration time is 12.6 seconds. Equipped with a 1.5T+CVT powertrain, the Ford Equator pursues a comfortable and smooth driving experience. During the 0-100km/h acceleration test, the Equator maintains a quite stable posture at launch without noticeable wheel slip. The maximum engine speed at launch can be maintained around 2500rpm, delivering continuous linear acceleration. Through multiple acceleration tests, the Equator's acceleration time remains around 12.6 seconds. The relatively smooth speed curve indicates that the CVT transmission makes the entire acceleration process quite smooth. Judging from the G-value, the maximum acceleration at launch only reaches 0.5g, meaning the acceleration doesn't deliver strong push-back sensation. The driving experience is rather comfortable, which aligns with the Equator's power characteristics.

Diagnosis of No-Spark Fault in EFI Vehicles' High-Voltage System?

High-voltage no-spark fault diagnosis and troubleshooting: 1. First, eliminate loose external wire connection faults. 2. Turn on the ignition switch without starting, observe the malfunction indicator lamp on the dashboard. If the lamp is on, it indicates normal ECU power supply; otherwise, inspect the power circuit. 3. Read fault codes. If present, repair components according to the fault codes. Possible causes include interrupted ECU power supply, absence of NE signal during startup, or missing IGT/IGF ignition control signals. 4. If no fault codes are present, it indicates normal operation of the ECU, induction coil, and electronic ignition module. The fault may lie in the high-voltage coil, distributor rotor, or distributor cap. 5. Use a multimeter to test primary and secondary resistances of the ignition coil. If normal, the fault likely exists in the distributor rotor or cap. Verification of repair effectiveness: Start the engine and vary its speed across medium and high operating ranges. Smooth engine operation with responsive acceleration confirms successful fault resolution.
