If the radiator hose is showing signs of wear such as cracks, bulges, or leaks, then it is recommended to replace it. A damaged radiator hose can lead to coolant leaks, overheating of the engine, and potential engine damage. It is better to replace the hose preventatively rather than risk a breakdown or more costly repairs in the future. If you are unsure about the condition of the hose, it is best to have a mechanic inspect it for you. **

The radiator hose likely burst due to a combination of factors such as age, wear and tear, and high pressure. Over time, the rubber in the hose can degrade and become more prone to cracking and bursting. Additionally, if the cooling system is not properly maintained and the coolant levels are not regularly checked, it can lead to overheating and increased pressure within the hose, causing it to burst. It's important to regularly inspect and replace radiator hoses to prevent unexpected failures. **
