What Causes High Temperature in Loaders?
3 Answers
The causes of high temperature in loaders may include loose engine fan belts, poor water circulation in the radiator, or clogged radiator fins. Here are the solutions: Check the coolant: Insufficient coolant will generate a large amount of underutilized heat, resulting in poor heat dissipation. Check the thermostat: Common thermostat failures include the main valve not fully opening or getting stuck between large and small circulation loops, aging, or poor sealing causing expansion body leakage. Check the engine: Focus on the engine oil level. Overfilling will increase resistance during operation, while insufficient oil affects lubrication and heat dissipation. Check the fan: Broken or fatigued fans directly cause the cooling fan to stop or run at low speed, affecting the engine's heat dissipation.
Overheating in loaders is something I encounter quite often. Last month, when I was driving my friend's machine, the temperature gauge shot up almost to the red line, forcing me to pull over immediately. The main causes are issues with the cooling system, such as insufficient coolant or leaks—if you don't check regularly, it can easily run dry. Another common problem is a clogged radiator, where dust or debris blocks the fan, preventing proper airflow. Loose or broken fan belts can also prevent the engine from driving the fan effectively. A faulty water pump may disrupt coolant circulation. Additionally, overloading the machine during operation puts extra strain on the engine. In high-temperature environments, it's especially important to avoid prolonged operation. My advice is to check the coolant level before each trip, take breaks during operation, and avoid pushing the machine too hard. If overheating occurs, shut down the engine immediately and inspect it—otherwise, severe engine damage may lead to costly and time-consuming repairs.
Hey, as someone who's worked with many construction vehicles, loader overheating is mostly caused by mechanical failures. The most common issue is a clogged radiator, where dust and sludge buildup affects heat dissipation; incorrect coolant concentration or aging and failure; problems with the fan system, including broken fan blades or clutch failure; water pump seal leaks reducing cooling efficiency; then there's the thermostat stuck in the closed position, preventing coolant flow; loose belts causing insufficient power transmission; plus insufficient or dirty engine oil, increasing engine friction and generating excess heat. In terms of operation, low idle or high load can easily cause trouble. It's recommended to regularly clean the radiator grille, ensure the correct ratio when changing coolant, and test with professional equipment. If overheating isn't addressed, the engine's lifespan will shorten over time, which isn't worth the cost.
