Here are the specific reasons why the air conditioning in a Haval H6 may not be cooling sufficiently: 1. Insufficient or low refrigerant: This may be caused by a minor refrigerant leak. You can observe this through the sight glass on the dryer tank. During normal operation of the air conditioning, if continuous bubbles appear in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it indicates a severe shortage of refrigerant. In this case, simply adding refrigerant will resolve the issue. 2. Loose drive belt of the car air conditioning compressor: If the drive belt is loose, the compressor may slip during operation, leading to reduced transmission efficiency and a decrease in compressor speed. This results in reduced delivery of compressed refrigerant, causing the car air conditioning to not cool properly. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it indicates the belt is too tight and should be slightly loosened. If tightening is ineffective, or if the drive belt shows signs of cracks, aging, or other damage, it should be replaced with a new one.

Which is better, tire speed rating H or T?

Tire speed rating T or H depends on the specific situation. Here is a detailed introduction to tire speed ratings T and H: 1. T and H represent the speed grades of tires. T indicates a maximum speed of 190 KM/H, while H indicates a maximum speed of 210 KM/H. The H rating is higher. 2. From a data perspective, H-rated tires are better as they can withstand higher speeds and are considered high-performance tires, more suitable for mid-to-high-end vehicles. On domestic roads, highways generally have speed limits around 120 KM/H, making H-rated tires somewhat overkill. For ordinary vehicles that do not require high-speed performance from tires, choosing T-rated tires is more practical as they meet the daily needs of most vehicles.
