How to Deal with High Water Temperature in Sinotruk HOWO?
3 Answers
If on the highway, increase the placement distance of the warning sign to at least 150 meters. If not effectively cooled, it may damage the engine. Open the engine hood and check if the coolant level in the auxiliary tank is normal. If there is water leakage from the hose, it indicates that the high water temperature may be caused by the leakage.
When driving a Sinotruk HOWO truck on the road and encountering high water temperature, immediately pull over to a safe spot, turn on the hazard lights, and ensure safety. Do not continue driving. Wait for the vehicle to cool down for at least half an hour before slowly opening the hood to check the coolant reservoir level. If it's low, promptly refill with the appropriate antifreeze, but be cautious of steam burns. Also, listen to see if the fan is running. If it's not spinning, it might be due to a blown fuse or a stuck fan that needs replacement. For short-distance emergencies, you can turn the air conditioning to the maximum heating setting to assist in cooling. Common causes of high water temperature include worn-out water pump bearings causing poor circulation or a stuck thermostat that won't open. Avoid overloading or prolonged uphill driving in daily use. This issue affects engine longevity, so it's best to visit a reliable repair shop for a thorough inspection of the water pump, radiator, and system leaks to prevent potential engine damage.
It's really annoying to keep encountering the water temperature alarm in my Sinotruk HOWO. Here's how I usually handle it: After stopping the car, first check if the coolant is leaking or low, especially inspecting joints and water pump for seepage. If the fan isn't working, check the fuse box near the driver's seat to see if it's blown and try replacing it. The main cause of high water temperature is poor heat dissipation—the radiator might be clogged with dust. If you can't clean it yourself, seek professional cleaning. Driving habits matter too—avoid prolonged idling when hauling cargo, and maintain appropriate speed on highways for better radiator airflow. For prevention, check water levels monthly, and use high-quality coolant to extend system lifespan and ensure safe operation. For a long-term solution, have a mechanic perform a pressure test to identify issues—spending a few hundred bucks can save you future headaches.
