There are several main reasons why the clutch pedal feels stiff and rough when lifting: 1. Dirty or rusted linkage mechanisms: Prolonged use leads to severe wear, insufficient lubrication, and excessive resistance. Remove the clutch assembly for cleaning and maintenance (replace parts as needed), lubricate, and adjust the clearance to standard specifications. 2. Clogged hydraulic lines: The hydraulic oil in the clutch master and slave cylinders, as well as the pipelines, is dirty, or the rubber cups, seals have deteriorated, or the oil passages are blocked. Disassemble the clutch master and slave cylinders along with the pipelines, thoroughly clean them with alcohol, blow them clean with high-pressure air (especially the pipelines), replace the rubber cups and seals in the master and slave cylinders, bleed the air, and adjust the clearance according to regulations.

Can 195 tires be installed on a vehicle originally equipped with 185 tires?

Can 195 tires be installed on a vehicle originally equipped with 185 tires? The introduction to tire specifications is as follows: Classification of tire specifications: There are many ways to represent tire specifications, and the four most common types in the market are British, German, metric, and American standards. For American standards, the first letter indicates the type of vehicle the tire is suitable for, the second letter represents the tire width, the third character denotes the aspect ratio, the fourth letter is the speed rating, and the last indicates the suitable rim diameter. Misconceptions about tire specifications: Many believe that the original specifications must remain unchanged. The incomplete range of imported tire specifications is largely due to market speculation by foreign suppliers. Some foreign suppliers prioritize profit over the actual needs of customers, which is their guiding principle. Many consumers, lacking professional knowledge, are unaware of the tricks for interchanging tire specifications and thus can only hope for the arrival of original imported tires.

How many types of spark plugs are there for cars?

Spark plug models can be categorized by material into: nickel alloy spark plugs, platinum spark plugs, and iridium spark plugs; by shape into: standard spark plugs, electrode spark plugs, extended insulator spark plugs, seat-type spark plugs, and surface-gap spark plugs; by heat range into: cold-type spark plugs and hot-type spark plugs (such as extreme combustion iridium spark plugs, which save over 10% fuel consumption, performing well in terms of car fuel efficiency). Below is relevant information about spark plugs: 1. Function: Commonly known as a spark plug, its role is to discharge the high-voltage pulses sent by the high-voltage wire (spark plug wire), breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. 2. Principle: The spark plug works in conjunction with the ignition system and fuel supply system to enable the engine to perform work, collectively determining the engine's performance to a large extent.

What causes the brake lights not to illuminate when the Corolla is using cruise control?

The reasons why the brake lights do not illuminate when the Corolla is using cruise control include issues with the brake switch, brake light wiring, brake light bulbs, or a blown fuse in the circuit. Checking the brake light bulbs: The brake lights are the most frequently used lights on a car, and the bulbs have a relatively short lifespan. When the brake lights fail to illuminate, the first thing to consider is the brake light bulbs. Simply replacing the bulbs may solve the issue. Checking the brake light switch: If the brake light switch is faulty, none of the brake lights will illuminate. During inspection, you can use a wire to bridge the brake light switch. If the brake lights turn on, it indicates that the switch is defective, and replacing it will resolve the problem. Checking the fuse: If both the bulbs and the switch are confirmed to be functioning properly, the next step is to check the fuse. Some cars do not have a dedicated fuse for the brake lights and share a fuse with other electrical devices. In this case, you can check the operation of other electrical devices in the car. Identify any non-functioning devices and replace the corresponding fuse.

Is Antifreeze Universal?

Antifreeze is not universal; you must use the same brand of antifreeze. Different brands of antifreeze have varying production formulas, and mixing them may lead to chemical reactions between multiple additives, rendering them ineffective. The basic indicators of antifreeze are its freezing point and boiling point. In the market, antifreeze comes in several specifications with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned.

Is it acceptable to have a car with waterlogged floor?

Waterlogged floor is acceptable. Water reaching the floor position is not considered severe, but it is still recommended to go to a 4S shop for further inspection. Reasons: For a waterlogged vehicle, the most feared damages are to the engine and electrical systems. Generally, it is safe as long as the water level is below the air intake. Different car models have varying heights for the engine air intake and different levels of electrification and lowest electrical positions. In most cases, it is fine if the water level slightly exceeds the cabin floor. Measures: Notify the insurance company and request the insurer's staff or an authorized third-party appraiser to conduct an on-site inspection. However, in general, when faced with a large number of waterlogged vehicle cases, insurance companies often cannot arrive at the scene promptly. You can request the insurance company, the car owner, or the insured to take photos of the waterlogged situation at the scene with a camera or mobile phone as evidence for claims. Before the rescue tow truck arrives, disconnect the vehicle's battery power immediately to avoid accidental startup during towing, which could exacerbate the vehicle's damage. You can also request the insurance company to provide towing assistance.
