Where is the thermostat located in the Wuling Hongguang S?

The thermostat in the Wuling Hongguang S is located next to the engine block. Introduction to the thermostat: The thermostat is a valve that controls the flow path of the coolant. It is an automatic temperature-regulating device, usually containing a temperature-sensitive component that opens or closes the flow of air, gas, or liquid through expansion or contraction. How the thermostat works: The thermostat automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The thermostat must be kept in good technical condition; otherwise, it will severely affect the normal operation of the engine.
I've been driving the Wuling Hongguang S for several years and have repaired it myself multiple times. The thermostat is usually hidden at the engine's water outlet, near the water pump. After opening the hood, if you look at the cooling hose system, you'll find a small cylindrical or box-shaped component clamped between hose connections, possibly obscured by radiator hoses and wires, making it difficult to see directly. It's recommended to start the operation after the engine has cooled down, using a wrench to gently loosen the connecting screws to avoid damaging the hoses or leaking coolant—that stuff can spray out and cause burns. If the temperature gauge rises too quickly or the heater isn't effective in winter, there's an 80% chance the thermostat is stuck, and it needs to be addressed promptly. Don't underestimate it; although small in size, it controls the entire cooling cycle. Long-term neglect may lead to engine overheating and cylinder scoring, resulting in high overhaul costs. During regular maintenance, use a mirror to inspect and clean dust and deposits for easier checks.
As a novice car owner, I was initially confused when trying to locate the thermostat on my Wuling Hongguang S. After checking materials, I learned it's positioned at the front of the engine compartment, attached to the water pump hose. Specifically, open the hood, look down at the engine, and find where several thick hoses converge - that small valve-like component is the thermostat. The location is somewhat hidden; if unfamiliar, try viewing from the front of the car - it's not far from the radiator but easily confused with other parts. Always let the engine cool for half an hour after shutdown before working, and wear gloves to prevent burns. A faulty thermostat causes erratic water temperature fluctuations, with dashboard warning lights activating. During my learning process, I discovered many illustrated videos shared on owner forums that clearly show the location. For safety, avoid forcing dismantlement yourself as damaged hoses can create bigger repair issues. Knowing its position enables preventive maintenance to avoid roadside breakdowns.
