Where is the thermostat located in the Wuling Hongguang 1.2 engine?

[LucyMarie]

The thermostat of the Wuling Hongguang 1.2 engine is located at the junction of the upper water pipe and the cylinder head. The thermostat is a valve that controls the flow path of the coolant, serving as an automatic temperature-regulating device. It typically contains a temperature-sensitive component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction. The Wuling Hongguang 1.2L is a 5-door, 7-seat MPV with body dimensions of 4305mm in length, 1680mm in width, and 1750mm in height, with a wheelbase of 2720mm. It is equipped with a 1.2L naturally aspirated engine and a 5-speed MT transmission, delivering a maximum power of 63 kW at 6000 rpm and a maximum torque of 108 Nm at 4000 rpm. The vehicle features front-engine, rear-wheel drive, with a MacPherson independent front suspension and a five-link swing-arm independent rear suspension.

Attention to all Wuling Hongguang owners with the 1.2L engine – you need to locate the thermostat correctly. It's positioned on the left side of the engine, beneath that round metal cover near where the water pump connects to the upper radiator hose. During a previous repair, I noticed mechanics had to remove the intake manifold just to access it – the space is really tight there. If the thermostat gets stuck, your dashboard coolant temperature gauge will spike abruptly, especially during summer when issues are more prone to occur. Remember last time my neighbor's car 'boiled over' due to thermostat failure, spraying coolant all over the engine hood. These small components are often overlooked during routine maintenance, but when they fail, it causes serious headaches. I recommend asking your mechanic to routinely check the sealing ring for aging or coolant leaks during servicing.

I've repaired quite a few Wuling Hongguang engines, and the thermostat for the 1.2L model is located right at the cylinder head's water outlet. To be specific, it's positioned on the upper left side of the engine, appearing as a small copper canister with two hoses attached. When replacing it, you need to drain the coolant first, then remove the three screws on the mounting bracket. Once during winter repairs, I encountered a thermostat stuck by scale, causing the engine temperature to take forever to rise after a cold start, and the heater wouldn't warm up. It turned out the owner had been using tap water directly. So I recommend using proper coolant and replacing it every two years to prevent such issues. If doing it yourself, remember to apply a bit of sealant around the edges before installing the new gasket.

The thermostat of the Wuling Hongguang 1.2 is hidden above the radiator on the front side of the engine, connected to the thick upper hose. During the last maintenance, I specifically asked the technician, and he said you need to remove the engine cover to see that round component with a spring. This part mainly controls the switching of the coolant circulation path—the small and large circulation loops rely on it. I've noticed many car owners aren't aware of this component until the temperature gauge hits the red zone. In reality, it fully opens at around 87-90°C. If the engine warms up too slowly during long winter drives, it's likely the thermostat opened prematurely and needs replacement.

Partners who use Wuling Hongguang for cargo hauling should know that the 1.2 engine thermostat is installed right next to the timing belt cover. Looking down from the engine compartment, you can see a black plastic water chamber connected to hoses. Opening the water chamber cover allows you to remove the thermostat. Last winter, my car suddenly had no warm air, and after troubleshooting for a long time, it turned out this part was broken, causing the engine to run too cold. Replacing it isn't too complicated but requires patience, as you need to remove five or six screws with a socket wrench. A quick reminder: when buying a new part, confirm the opening temperature parameter—using the wrong model might increase fuel consumption. It's best to get an original part from a service station, as aftermarket parts can sometimes get stuck within three months.

I remember the first time I tried to replace the thermostat on my Wuling Hongguang 1.2, the location was really tricky to find. Eventually discovered it in the narrow gap between the engine and firewall – that bulge above the water pump is it. This component is crucial for maintaining proper engine operating temperature. When faulty, it causes two extreme scenarios: either the coolant won't heat up properly in cold weather leading to increased carbon buildup, or the engine will overheat during hot days. An experienced friend taught me to diagnose it by feeling the temperature difference between upper and lower radiator hoses – after normal warm-up, both hoses should be piping hot. If the upper hose is hot while the lower one stays cool, there's a 90% chance the thermostat is stuck. Owners who frequently drive mountain roads should consider keeping a spare in the vehicle.
