In summer, an oil temperature of 90 degrees Celsius is considered normal for cars. Engine oil operating temperature: The normal operating temperature of engine oil is around 90 degrees Celsius. However, in the areas it serves, particularly the combustion chamber of the engine, temperatures can exceed 200 degrees Celsius. Engine oil operating temperature range: The normal operating temperature range for engine oil is generally 70-90 degrees Celsius, with some localized areas being higher. It typically doesn't exceed the coolant temperature. Additionally, at higher speeds, the temperature may rise to around 100-110 degrees Celsius. However, if there's a consistent trend of temperatures exceeding 120 degrees, an inspection should be performed.

How often should the transmission fluid be changed for a Focus?

Ford Focus manual transmission fluid is designed for long-term use and is theoretically maintenance-free, requiring only regular inspections. The automatic transmission fluid should be changed for the first time at 55,000 kilometers, and then every 60,000 kilometers thereafter. Below is an introduction to transmission fluid: 1. Its main function is to keep the gear shifting system clean and to lubricate the transmission components, extending their lifespan. Due to differences in transmission design, transmissions are divided into manual and automatic (which further includes CVT, AMT, etc.). Each type of transmission has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, speed, structure, etc. Therefore, the manufacturer specifies its own dedicated transmission fluid. 2. When changing the transmission fluid, some old fluid will remain in the transmission channels and torque converter. When different fluids are added, the mixture of the two different fluids inside the automatic transmission may reduce the performance of the automatic transmission fluid, leading to poor lubrication or abnormal operation of the automatic transmission, which can severely damage the automatic transmission.

How to Step on the Clutch Steadily

Manual transmission stepping on the clutch steadily method is: use the front part of the foot to press the clutch pedal deeply with the heel of the left foot as the fulcrum, and the action should be slow when releasing the foot. The clutch is installed between the engine and the transmission, and its functions are: 1. ensure a smooth start of the car; 2. achieve smooth gear shifting. The clutch is divided into: 1. electromagnetic clutch; 2. magnetic particle clutch; 3. friction clutch; 4. hydraulic clutch. The manual transmission starting method is: 1. step on the clutch and turn the key to the ACC gear, stay for about 3 to 5 seconds and then turn to the START gear to ignite; 2. step on the clutch to shift gears, and release the handbrake.

Where is the rear fog light located on a car?

Car rear fog lights are located on the left side or both sides of the taillights. When driving in adverse weather conditions such as fog, snow, heavy rain, or in smoke-filled environments, front fog lights must be used to illuminate the road ahead and ensure driving safety. The main functions of fog lights are: 1. Front fog lights are used to improve illumination when the road conditions ahead are unclear and to alert oncoming drivers. 2. Rear fog lights help vehicles behind to spot the car in low visibility conditions. The usage of fog lights is as follows: 1. When visibility is between 100 to 200 meters, fog lights, low beams, width indicator lights, and taillights must be turned on, maintaining a distance of more than 100 meters from the vehicle ahead. 2. When visibility is between 50 to 100 meters, fog lights, low beams, width indicator lights, and taillights should be turned on, keeping a distance of more than 50 meters from the vehicle ahead.
