What are the causes of coolant pipe burst?

[NicoleLynn]

The causes of coolant pipe burst are rubber pipe aging, insufficient coolant, and high pressure in the cooling system. Rubber pipe aging: Prolonged exposure to intense sunlight causes the rubber components to age due to ultraviolet rays; chemical factors; high temperature. Exposure to intense sunlight and high temperatures from the engine accelerate the volatilization or transformation of components in the rubber, leading to hardening and cracking of the rubber. Solution: At this point, it is necessary to inspect and replace damaged parts, replace the rubber pipe, and promptly replenish the coolant. Insufficient coolant: Low levels of automotive coolant can easily cause the engine to overheat, leading to engine damage. The normal operating temperature of an engine is between 90 degrees Celsius and 120 degrees Celsius. Insufficient coolant can easily cause the engine to overheat or the coolant pipe to burst. Solution: At this point, it is necessary to promptly replenish the coolant. High pressure in the cooling system: The cause of high pressure could be high temperature or leakage from the cylinder head gasket. Solution: Promptly visit a 4S shop for repair.

I've seen plenty of antifreeze hose bursts in my decades of tinkering with cars. The most common cause is aging rubber hoses becoming brittle and failing under system pressure. Blockages in the system, like debris stuck in the radiator or a faulty radiator cap that can't relieve pressure, can also lead to hose bursts when pressure builds up. Temperature extremes are another major issue – excessive contraction in winter or expansion can crack hoses that can't flex properly. I've also encountered poorly secured hose connections and severe corrosion, especially when the antifreeze mixture is incorrect, accelerating corrosion. If a hose bursts, don't just patch it up – inspect the entire cooling system first; a pressure test can reveal hidden problems. For maintenance, never skimp on quality when replacing hoses, and inspect all rubber hoses every two years.

My own car recently had a coolant hose burst, causing a puddle of fluid to leak everywhere—luckily, nothing serious happened. After checking, it turned out to be caused by aging and cracking of the hose combined with excessive system pressure. Old hoses become brittle after five or six years of use, and if there's air in the pressure system or a cooling fan failure, the pressure can skyrocket. Large temperature fluctuations also contribute—expansion in heat and contraction in cold can cause the hose to burst if it lacks sufficient strength. Corrosion is another factor, such as expired coolant turning acidic or excessive scale buildup, which can rot the hose from the inside. A piece of advice: before driving, feel the hose’s flexibility—if it’s as hard as a rock, it’s time for a replacement. A simple swap can prevent the risk of a breakdown.

Bro, coolant hose bursts are pretty common. The hose deteriorates and can't handle the pressure. If the cooling system gets clogged or the fan gets stuck, the pressure spikes; when temperatures change drastically, the hose expands and contracts violently, making it prone to cracking. Corrosion is also an issue—deteriorated coolant can corrode the hose walls. Loose hose connections can also cause localized high pressure and bursts. For prevention, I insist on replacing hoses regularly—retire them every five or six years—and routinely check for cracks or signs of softening. Don’t forget to maintain the correct coolant ratio for anti-corrosion to keep the system safe.
