Can I still drive if the coolant warning light comes on?

If the coolant warning light comes on, you should not continue driving. You must stop immediately and add coolant according to the actual situation. Under normal circumstances, the coolant in a running vehicle should not trigger a warning. When the warning appears, it indicates that the coolant level is insufficient to maintain the normal operation of the car, and the engine's cooling performance will deteriorate. Continuing to drive under these conditions can lead to engine damage. The engine is a crucial component of the vehicle, and if it is damaged, the car may be rendered unusable. If the engine temperature is not excessively high, you may drive to a safe location, but you must monitor the temperature gauge to ensure it does not reach the red line, which indicates overheating. It is best to let the engine idle to help lower the temperature and avoid causing further damage to the vehicle by continuing to drive.

What is the function of the oil ring?

The function of the oil ring is to scrape off excess oil from the cylinder wall and spread a uniform oil film on the cylinder wall. This prevents oil from entering the combustion chamber and reduces wear between the piston, piston rings, and cylinder wall. The following is an introduction to the oil ring: 1. The oil ring is a type of piston ring, divided into ordinary oil rings and composite oil rings. 2. Ordinary oil rings are generally made of alloy cast iron, with a groove cut in the middle of the outer surface and many small oil drainage holes or slits processed at the bottom of the groove. 3. The composite ring consists of upper and lower scrapers and a spacer spring that provides radial and axial elasticity. This type of oil ring has very thin scrapers, high specific pressure on the cylinder wall, strong oil scraping ability, and independent upper and lower scrapers, making it highly adaptable to the cylinder.
