How to Solve High Water Temperature in Trucks?
2 Answers
Maintain the engine at idle speed, strictly prohibit shutting off the engine, and pour cold water on the surface of the radiator to accelerate cooling. Use a wet towel to unscrew the radiator cap for cooling, and finally, be sure to check if the oil dipstick is within the normal range. At this point, open the oil filler port in the parked state, add lubricating oil, and after filling, use any method to shut off the engine.
I've been driving trucks long-distance for twenty years, and I always handle overheating issues calmly, because pushing through can ruin the engine. The first thing to do is immediately pull over, turn off the engine, and let it cool down—never keep driving, as high temperatures can warp the cylinders or even cause a fire. Then, open the hood but don’t touch the radiator cap right away to avoid burns. Once it cools a bit, check the coolant level—if it's low, top it up with distilled water or specialized coolant. Is the fan running? Feel for airflow with your hand; if it’s not moving, the belt might be loose or the motor could be faulty. For a quick fix, clean external dirt from the radiator, but it’s best to get a professional to check the water pump or thermostat. I always recommend checking coolant levels weekly and cleaning the radiator monthly to prevent clogs and ensure safety.
