How to Check the Engine Oil Level in a Lynk & Co 01?

The method to check the engine oil level in a Lynk & Co 01 is: 1. The oil dipstick of the Lynk & Co 01 is located on the dashboard. Without pressing the brake pedal, hold down the start button for ten seconds, and the oil condition will be displayed on the dashboard; 2. When checking, ensure that all four wheels of the car are parked at the same horizontal level, and the body should not be tilted. If the body is tilted, the oil level in the oil pan will change, resulting in inaccurate measurements. Taking the 2020 Lynk & Co 01 as an example, it belongs to the compact SUV category, with body dimensions of: length 4512mm, width 1857mm, height 1689mm, a wheelbase of 2734mm, and a curb weight of 1736kg.

How long does it take to get the car back after a full-body paint job?

Different 4S shops have varying paint job durations, typically around one week to get the car back. Below are methods for maintaining car paint: 1. Apply a paint protection film (PPF): PPF effectively protects the vehicle's paint, causing no harm to the original paint while ensuring the paint's glossiness. It's currently a highly recommended method. 2. Characteristics of PPF: PPF is applied in separate sections. Each section is independently applied, allowing for direct replacement if damaged without affecting other sections of the film.

What Causes Abnormal Noise During Engine Idling?

Engine idle abnormal noise may be caused by the following reasons: Timing chain elongation, tensioner pressure loss, balance shaft wear: Timing chain elongation is generally caused by metal fatigue. After prolonged driving combined with the high-temperature working environment of the timing chain, elongation can easily occur, leading to abnormal noise. The tensioner is connected to the oil passage and adjusts the tightness of the timing chain through oil pressure. If the tensioner oil passage is blocked or the internal check valve loses pressure, the chain may loosen and produce noise. The balance shaft is used to reduce vibrations generated during engine operation. If the balance shaft oil passage is blocked, it can increase wear on the journal and bearings, resulting in noise. Camshaft, crankshaft, and connecting rod bearing wear: If the vehicle uses low-quality oil, excessive sludge may form in the engine, blocking the lubrication oil passages and preventing oil from reaching components that require lubrication and cooling. This can cause wear on the camshaft, crankshaft, and connecting rod bearings, leading to noise. Additionally, if the engine lacks coolant, causing excessive engine temperature, the above phenomena may also occur. In severe cases, it can even lead to cylinder scuffing or bearing seizure. Increased timing variable wheel clearance: Variable valve timing can adjust according to engine speed and operating conditions, typically using hydraulic control to advance or delay the camshaft timing gear's internal rotor by a certain angle. If the variable timing wheel's internal rotor is stuck or the oil cavity is worn, the clearance may increase, causing noise. Excessive valve clearance or damaged rocker arm: The rocker arm is a lever mechanism that presses the valve, and the valve clearance is mainly controlled by the hydraulic lifter. Damage to either can result in valve noise.
