High temperatures can be dangerous, especially when vehicles are left in the sun for long periods. This can lead to serious issues such as vehicle fires or even accidents that result in injuries. That's why it's important to give your machinery a "cooling down" after summer ends.
When dealing with overheating in engineering vehicles, it's crucial to handle it properly. If the engine temperature rises too high, some people might rush to open the radiator cap to cool it down. However, this is extremely risky, as hot water and steam can spray out and cause burns. Always let the engine cool naturally before opening the cap or adding water.
Another common mistake is using cold water to quickly cool down the brakes or other components like the loader transmission. This sudden temperature change can damage parts, cause warping, or even cracking. It's always better to allow the system to cool on its own without interference.
One of the most important steps is not to shut off the engine immediately after it starts boiling. When the cooling system has air bubbles, the circulation of coolant is disrupted. Even if there's water in the radiator, the cylinder walls may not be adequately cooled. This can cause expansion of internal parts, leading to damage once the engine is turned off. Soft metals might fall off, and critical components could stick together.
After the engine starts to boil, never try to open the radiator cap right away. The pressure inside the system is very high due to the boiling water and steam. Removing the cap suddenly can cause scalding and serious injury. Wait until the engine has cooled down naturally before attempting any action.
It’s also dangerous to pour cold water directly onto the engine block or cylinder head when it’s overheating. This sudden cooling can cause thermal shock, which may result in cracks or permanent damage to internal components. Avoid this practice at all costs.
Finally, don't add cold water directly to the radiator when the engine is overheating. This can create a rapid increase in pressure as the cold water meets the hot engine. The resulting steam can burst out of the radiator, causing severe burns. Always wait for the engine to cool before refilling the coolant.
