You may have noticed steam boiling out from under the hood. Or, maybe, the coolant/water-temperature gauge is no longer where it used to sit comfortably. The sweet, syrupy smell of diesel engine oil coolant is also common with an overheating engine. As said, low coolant level is the first potential cause to investigate. Look for coolant leaks on the ground under the radiator and engine. Better yet, have a mechanic pressure test the system.
Check the oil level to ensure coolant isn’t leaking into the engine. Fix any leaks you find. A bad cooling fan is another potential cause. Start the vehicle and crank the air conditioning. Check under the hood to ensure the cooling fans are spinning. A bad fan won’t pull sufficient air across the radiator to cool the commercial engine oil. Check the fuse first. If it’s fine, the motor may be burned out or the thermostatic switch may have failed.
A faulty thermostat is another prime culprit. The thermostat should close until the engine warms and then open after it’s hot to allow coolant to flow through the system. If it sticks shut, coolant can’t flow, increasing engine oil heat. If the engine is warm, but the upper radiator hose is cool to the touch, it could mean the thermostat is bad. A thermostat is so inexpensive that it’s often easier to simply replace it than try to troubleshoot it. The same applies to a faulty radiator cap. If you want that your engine is always remain in new condition then use the high performance lubricants in Dubai.
A radiator plugged with sludge or corrosion can also cause your engine to overheat. It may look fine on the outside while the inside is a mess. Then again, it may not look fine on the outside. Check for leaves, grasshoppers and other junk plugging the fins and blocking airflow. One trick is to shine a flashlight through the radiator from under the hood. Look through the vehicle’s grill. If you can’t see the light, the radiator needs cleaning. For the betterment of your engine, you can contact to ISO certified lubricant oils in Dubai.
Plugged coolant passages will likely accompany a bad radiator. Using a low-quality conventional coolant or failing to service the cooling system can cause sludge or corrosion to build up in the system. Just like your arteries need to be clean to flow blood through your body, the radiator and cooling passages must be clean to properly flow coolant. If not, the engine can overheat. In this case, flush the system, replace the radiator and refill with a high-quality coolant. Please contact to the Dubai’s best high performance lubricants technolubeuae today.
