What causes the high water temperature in Haval H6?

[StBarrett]

The reason for the high water temperature in Haval H6 is that coolant leakage or insufficient coolant can prevent the engine from cooling properly, leading to elevated engine water temperature. Additionally, a dirty engine radiator can also cause the engine's water temperature to rise. The radiator has many pores formed by cooling fins, which are prone to accumulating debris, dust, and sludge, reducing ventilation and diminishing cooling efficiency. Poor radiator cooling can result in insufficient engine cooling, causing the engine's water temperature to increase. Additional Information: Excessive water temperature in a car engine can cause the cylinder head to deform. This deformation may further lead to poor sealing, direct damage to the cylinder gasket, and mixing of coolant into the oil passages, reducing the lubrication effectiveness of the engine oil. This can further damage various engine components until the engine overheats.

A couple of days ago, my buddy's Haval H6 also experienced an overheating issue. Here are some key takeaways: First, insufficient or degraded coolant—older cars often have hose leaks, so pop the hood and check the overflow tank level. Second, a faulty radiator fan, especially common in summer traffic jams—try turning on the AC to see if the fan kicks in. Third, issues with the water pump or thermostat—last time, I had a stuck thermostat that blocked coolant circulation. Fourth, radiator fins clogged with pollen or insect debris—a quick rinse with a hose usually does the trick. Most critically, watch for head gasket failure—if you spot white exhaust smoke or milky engine oil, shut off the engine immediately to avoid a major overhaul!

As a veteran H6 driver with 8 years of experience, I remind you not to push through when the water temperature warning light comes on. I once encountered a burnt-out fan relay - the fan appeared fine but wasn't receiving power. It was fixed by replacing the relay for just 80 RMB. Also, northern drivers should pay attention to antifreeze freezing points; insufficient concentration causing winter freeze-ups can block pipes. For vehicles with extensive lighting modifications, check alternator voltage - excessive voltage leading to insufficient cooling fan speed is a hidden danger. Remember to inspect hose connections monthly, as rubber hoses begin hardening and leaking after five years.

The three most common causes in repair shops: radiator blockage accounts for 40%, especially in vehicles that haven't been cleaned after driving over 50,000 kilometers; thermostat failure accounts for about 30%, manifested by a large temperature difference between the upper and lower hoses; the rest are due to water pump impeller corrosion or belt breakage. Recently, several cases of water ingress into the electric fan control module have been discovered. The H6's module is located near the left front wheel liner and is prone to short circuits after wading through water. Do not open the radiator cap immediately after parking, beware of steam burns!
