What are the criteria for tire replacement?

The standard for tire replacement is the degree of wear on the tire surface. When the tread depth on the tire surface is below 1.6mm, the owner must replace the tires as soon as possible. Continuing to drive under such conditions can easily lead to the risk of a tire blowout. During daily vehicle use, if the tread depth is greater than 1.6mm but there are visible cracks on the tire surface or bulges on the tire sidewall, the owner should replace the tires immediately, regardless of how long the tires have been in use. Generally, the service life of tires from different brands ranges from 3 to 5 years. After 5 years, tires almost always show significant signs of aging and hardening. Therefore, it is recommended that owners replace their tires regularly to avoid unpredictable dangers. Thus, when the wear on the tire surface poses a safety hazard, the tires should be replaced promptly.

Can You Drive with High Engine Coolant Temperature?

You should not continue driving with high engine coolant temperature. The normal operating temperature for an engine is 90 degrees Celsius, which ensures optimal engine performance and fuel efficiency while reducing wear and extending service life. Below are key points about engine overheating: 1. Both excessively high and low engine temperatures can lead to increased wear and reduced power output. Particularly, prolonged operation under high temperatures can severely damage the engine, potentially causing complete engine failure. 2. When the high-temperature warning light comes on, first reduce speed and pull over to the roadside. Do not immediately turn off the engine, as extreme heat causes components like pistons, cylinder walls, and crankshafts to overheat, thinning the engine oil and compromising lubrication. 3. Shutting down the engine at this point while components are thermally expanded (with minimal clearances) may cause soft metal parts to detach or even result in piston seizure. Therefore, after noticing overheating, maintain idle operation temporarily to facilitate cooling instead of turning off the engine immediately.

How often should platinum spark plugs be replaced?

Platinum spark plugs should generally be replaced every 60,000 kilometers. Below are the specific details: 1. The replacement interval should be analyzed flexibly based on actual conditions. If the vehicle is under warranty, strictly follow the replacement schedule specified in the maintenance manual. Failure to adhere to the manual's replacement guidelines may give the manufacturer grounds to deny warranty claims if engine issues arise. For vehicles out of warranty, spark plugs can be replaced every 40,000 to 50,000 kilometers. 2. Spark plugs are divided into two types: standard copper-core (nickel alloy) spark plugs and precious metal spark plugs (platinum, iridium). The main difference lies in the electrode material. Standard spark plugs have a service life of 30,000 kilometers, platinum spark plugs last up to 60,000 kilometers, and iridium spark plugs can endure up to 80,000 kilometers.

What to Pay Attention to When Applying for Driving School

Here are the things to pay attention to when applying for driving school: 1. Whether the driving school has its own regular training ground and where it is located (avoid signing up with Driving School A but practicing at Driving School B), and whether it is a private car owner affiliated with the driving school; 2. The reputation of the driving school, its pass rate, and the integrity of the instructors—these will directly affect how much you will spend on driving lessons; 3. Whether the driving school charges a one-time fee. Legitimate driving schools usually charge slightly higher fees, while some schools attract students with low prices but charge various additional fees during training, ultimately costing you thousands more than schools with higher initial fees; 4. When signing up, be sure to visit the training ground. Legitimate driving schools may even offer free trial lessons; 5. Whether additional fees are charged for using the training ground or for retaking lessons if you fail the test; 6. Whether the fee details are clearly stated in the contract and whether the contract uses the standardized numbered version issued by the transportation authority. Some branch schools use simplified contracts printed on A4 paper, and some privately affiliated schools may not even sign contracts, leaving students' rights unprotected.

What Causes Heavy Steering Wheel Feel?

Here are the reasons why the steering wheel feels heavy: 1. Insufficient power steering fluid/oil. Power steering fluid is a medium oil used in the car's power steering pump, which transmits steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the power steering fluid is insufficient, the steering will feel heavy and stiff. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Steering gear or power steering pump failure. The steering gear and power steering pump also affect the car's steering. Any malfunction in these two critical components can cause steering difficulties.
