What is the normal value of the Wuling Hongguang water temperature gauge?

Wuling Hongguang water temperature gauge 90 degrees is normal. Extended information is as follows: 1. Introduction: The inside of the car water temperature sensor is the car water temperature sensor. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. It is installed on the water jacket of the engine block or cylinder head and is in direct contact with the cooling water, thereby measuring the temperature of the engine cooling water. 2. Principle: The electronic control unit measures the temperature of the engine cooling water based on this change. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. The electronic control unit measures the temperature of the engine cooling water based on this change, which serves as a correction signal for fuel injection and ignition timing. Simply put, the engine water temperature can be used to understand the operating state of the car, whether it is stopped or moving, or how long it has been moving, etc.
When I drove the Wuling Hongguang on long trips, I paid special attention to the temperature gauge. The normal operating temperature for this vehicle usually fluctuates around 90 degrees Celsius, and it's safest when the needle points slightly below the middle of the gauge. If the temperature consistently stays below 70 degrees, there's an 80% chance the thermostat is stuck closed; if it rises above the red line at 100 degrees, it's likely due to insufficient coolant or a failed cooling fan. Once during summer traffic congestion, the temperature shot up to the red line, so I immediately pulled over, turned off the engine, and opened the hood to cool it down. Later, I found the radiator was clogged with willow catkins. Remember to check the auxiliary tank's fluid level monthly and have a mechanic test the coolant's freezing point during seasonal changes to prevent engine overheating and cylinder scoring.
I've been delivering goods with my Wuling Hongguang for almost five years. As long as the temperature gauge needle stays steadily in the middle area between the C and H marks, it's perfectly fine, which roughly translates to a temperature range of 85 to 95 degrees Celsius. During the break-in period of a new car, it might be about 5-6 degrees lower, and when climbing hills with AC on, it may rise by around 3 degrees at most. I remember last year when the radiator cap seal aged, the water temperature kept jumping to the warning line frequently. After replacing the cap which cost only 30 yuan, everything returned to normal. Now my car maintenance routine includes cleaning insects from the front grille every time I wash the car, and switching to -25-degree antifreeze before winter. After all, repairing an engine is much more expensive than regular maintenance.
