How long does radiator hoses last?
How long does radiator hoses last?
Coolant hoses typically last several years, though anything longer than 10 years may be pushing the limits. Rubber weakens with age and from repeated exposure to hot coolant, so the older they get the higher chance they’ll leak and cause the engine to overheat.
How do I remove the lower radiator hose?

What is the difference between upper and lower radiator hoses?
If you were to place them side by side, you’d find that they were different lengths and different shapes. They also do different jobs. The upper radiator hose is where the hot coolant enters the radiator from the engine. It cycles through the radiator, cooling as it goes.
Where does the coolant go when it enters the radiator?
The upper radiator hose is where the hot coolant enters the radiator from the engine. It cycles through the radiator, cooling as it goes. When it reaches the bottom, it moves out of the radiator through the lower hose and back into the engine to start the cycle once more.
What makes the air flow over a radiator?
Metal fins allow the heat absorbed by the coolant to radiate outward, where it is wicked away by moving air. Air flows over the radiator from two sources – the cooling fan (or fans) blow air over the radiator when it reaches a certain temperature. Air also flows over the radiator when you’re traveling down the road.
When to change radiator hose?
Every 3 to 5 years, radiator hose clamps and radiator hoses should be replaced so that the engine is in proper working order. With age and use they can become brittle, swollen, or corroded.
