Reduced circulation capacity, leakage, or abnormal noises can all indicate whether the radiator cap is damaged. Leakage issues are relatively easy to detect. Minor leaks will leave traces at the water pump vent, while significant leaks can be directly observed through water temperature and the ground under the chassis.

Why Doesn't Lexus Hold Its Value Well?

Lexus doesn't hold its value well for the following reasons: 1. Lackluster uphill performance, feeling somewhat cumbersome on steep slopes. 2. Sluggish acceleration when overtaking, often giving a sense of inadequate power during passing maneuvers. 3. At high speeds, without downshifting to increase engine RPM, the car feels particularly underpowered. Below is some information about Lexus: 1. Lexus (English: Lexus; Japanese: レクサス), founded in 1983, is a globally renowned luxury automobile brand under Japan's Toyota Group. The brand achieved sales surpassing Mercedes-Benz and BMW in North America within just over a decade. 2. Lexus was first introduced in North America, as the pronunciation of 'Lexus' closely resembles the English word 'Luxury,' creating an association with luxury vehicles. The Lexus logo features a capital 'L' from the name 'Lexus,' enclosed within an oval. The oval represents the Earth, symbolizing Lexus vehicles' global presence.

What maintenance is needed after a car has run 20,000 kilometers?

After a car has run 20,000 kilometers, the main maintenance items include the following: 1. Replace the engine oil and oil filter: Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance deteriorates substantially. Over time, it can no longer protect the engine effectively. The oil filter is replaced simultaneously to prevent impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. 2. The air filter's role is to block dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned for a long time, dust can enter the engine, causing abnormal wear on the cylinder walls. If it was not replaced during the 10,000-kilometer maintenance, it should be replaced at the 20,000-kilometer maintenance.
