Why does my radiator hose keep leaking?
Causes of Coolant Hose Leaks. Unfortunately, even the best hoses will eventually wear out over time. Hose leaks are the most common result of this, and they occur when cracks or abrasions form on the hose. Over time, the cracks get bigger, causing it to leak coolant.
Why does my radiator hose have so much pressure?
If your engine has overheated (due to a stuck thermostat, low coolant or for some other reason), it’s possible for superheated coolant to swell the hose. Swollen hoses should be replaced as soon as possible. This applies to radiator hoses, as well as other hoses under the hood.
How do you find a leak in a radiator hose?
Look for signs of coolant leakage—a light-colored residue or stain—around the radiator cap, on hoses throughout the engine compartment (check the ends where they are clamped to other components) and on the radiator itself. If it looks like a hose is leaking near a clamp, try tightening the clamp with a screwdriver.
How do I know if my radiator hose is leaking?
If your Low Coolant Light comes on, or you are having to constantly replenish the fluid, there’s probably a leak in the radiator hose. This type of leak will also create those green puddles underneath the vehicle, especially if the vehicle was parked for several hours.
Can a leaking radiator cause a blown head gasket?
A head gasket failure may have been caused by an engine overheating one too many times (as a result of clogged radiator, coolant leak, faulty fan, etc.), but a blown head gasket will also cause the engine to overheat too.
Should radiator hoses be soft or hard?
A radiator hose in good condition should feel firm, but not hard. A radiator hose in poor condition feels very hard, spongy, or soft. You may find a single soft spot as opposed to the entire hose being soft. A soft hose or a hose with a soft spot should be replaced.
What would cause a radiator hose to leak?

What are the symptoms of a leaking radiator hose?
A small leak or crack in a radiator hose can lead to major problems and expense. The most obvious sign of a leak in your radiator system is a low coolant level. Other symptoms that indicate a leak are small neon-green puddles underneath your car, and the smell of burnt antifreeze as the coolant drips on a hot engine.
What to do if you have a radiator leak?
Allow the engine to cool. Your radiator has the important task of helping to maintain the operating temperature of the engine.
How much does it cost to repair a radiator hose?
