What does H indicate on the FAW dashboard?
3 Answers
H on the FAW dashboard indicates the engine oil pressure condition. Below is relevant information about automotive engine oil: 1. Definition: Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a vehicle. 2. Precautions: When removing the oil pan drain plug, avoid using an adjustable wrench as it may damage the plug. Loosening the oil filler cap before draining can facilitate smoother oil flow. When tightening the oil pan drain plug, apply appropriate force—just snug—to prevent thread damage. Some oil pan drain plugs come with copper washers to prevent leaks; these washers and the drain plugs themselves require periodic replacement.
Last time I was driving my FAW truck on a long haul, when that 'H' lit up on the dashboard, I immediately knew the engine was overheating. That thing is actually the high-temperature warning light in the engine coolant temperature indicator, meaning the radiator was way too hot. I was climbing a slope at the time, so I quickly pulled over to let the engine cool down, only to find coolant leaking all over the place—probably due to aged hoses or the fan not spinning. Thankfully, I handled it in time; otherwise, engine seizure could've been a huge headache, costing thousands to repair. Now before every trip, I always check the coolant level and make sure the radiator is clean, and I keep an emergency coolant bottle in the truck. You've got to be extra careful in summer—if you're not paying attention, the engine temperature can skyrocket, and when that 'H' light comes on, you've got to act fast.
As a truck enthusiast, I'm very familiar with FAW trucks. The 'H' on the dashboard usually indicates the high coolant temperature warning light, which is the H symbol next to the thermometer icon. The reason is often a cooling system issue, such as a stuck water pump, clogged radiator, or faulty thermostat causing poor coolant circulation. For initial checks, carefully open the hood and feel if the radiator cap is hot (be careful not to burn yourself), then check if the coolant level is sufficient and look for any leaks. Many times it's caused by a loose fan belt or a broken fan that's not working - you can try tightening the belt or replacing the fan yourself. Regularly clean the radiator fins as accumulated dust reduces cooling efficiency and can lead to overheating. If the warning light frequently comes on, it's recommended to take it to a reliable repair shop for thorough inspection as soon as possible.
