Radiator hoses can collapse for several reasons, and it’s important to address this issue promptly as it can lead to overheating and damage to your vehicle’s engine. Here are some common reasons why radiator hoses may collapse:

So why do radiator hoses collapse?

1.Hose aging or damage
Hose may become slack or cracked after prolonged use or external physical damage, causing the hose walls to thin and collapse as it cannot withstand the pressure.
2.Lack of coolant in the cooling system
If there is not enough coolant in the cooling system, then the pressure inside the hose will be reduced and the hose will collapse because of the negative pressure inside.
3.Incorrect hose installation
Incorrect hose installation position and angle will cause air bubbles and air to be trapped inside the hose, these bubbles may block coolant flow and cause the hose to collapse.
4.High engine operating temperature
If the engine is running too hot, the pressure in the cooling system will increase, causing the hose to become slack and collapse.
5.Blockage in the cooling system
If there is a blockage in the cooling system, the flow of coolant will be impeded and the pressure inside the hose will increase, causing the hose to slacken and collapse.
6.Soft Hose Material
Radiator hoses may collapse due to weak material. Over time, exposure to heat and pressure can cause the hose material to break down and weaken. This can make the hose more likely to collapse under vacuum pressure.
7.Incorrect Radiator Cap
The radiator cap plays a crucial role in maintaining the proper pressure within the cooling system. If the radiator cap is faulty or the wrong type for your vehicle, it can lead to pressure issues that may cause hoses to collapse.

How to prevent radiator hose collapse

Now that we know the causes of a collapsed radiator hose, let’s look at some ways to prevent this from happening:
Regular maintenance
One of the best ways to prevent a radiator hose from collapsing is to perform regular maintenance. This includes checking the hoses for cracks, leaks or other signs of wear and tear. By catching any problems early, you can prevent them from becoming more serious and causing the hose to collapse.
Proper Installation
Proper installation is also critical to prevent radiator hose collapse. Make sure the hoses are properly installed on the radiator or engine and tightened to the correct torque specification. You should also avoid bending or twisting the hoses during installation.
Use quality hoses
Using high-quality radiator hoses can also help prevent collapse. Quality hoses are made of strong, durable materials that can withstand the heat and pressure of the cooling system. You can also choose reinforced hoses that are designed to resist collapse.
Flush the cooling system
Regular flushing of the cooling system helps prevent internal blockages that can cause radiator hoses to collapse. The flushing system removes any debris, rust or deposits that may accumulate in the hoses and radiator.
Drive your vehicle properly
Avoid overloading or driving at high speeds, as well as driving at low speeds for long periods of time, which can lead to high engine temperatures that can cause hoses to collapse.

In conclusion, a collapsed radiator hose is a common problem that can lead to engine damage if not addressed in a timely manner.
