Inspect the hoses and note any kinks or obvious signs of wear. Squeeze the radiator hoses (when cool ONLY) and see how they feel. If hoses are soft and pliable, there is no need to replace them. However, if hoses feel stiff, crackly, or brittle, they need to be replaced.
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Another common problem is clogging of the smaller radiator runoff hose, which leads to the coolant tank. As the engine cools, if fluid cannot return to the tank, this will also cause a vacuum.
There is no true set lifespan for a radiator hose. They should last for at least five years, but some will last longer, particularly if you’re vigilant about having your coolant changed and your vehicle maintained properly.
The average price that most car owners will pay for an overall radiator hose replacement is between $150 and $171 for the total radiator hose cost. The labor costs for this procedure range between $77 and $98, while the total parts cost for this mechanism is around $73.
While the engine is warm after a drive, squeeze the radiator hoses, paying particular attention to areas where the hose bends. A radiator hose in good condition should feel firm, but not hard. A radiator hose in poor condition feels very hard, spongy, or soft. … A soft hose or a hose with a soft spot should be replaced.
The proper torque for screw type hose clamps is to tighten them until the rubber outer shell protrudes through the screw slot just enough to be even with the outside of the clamp. Any further is considered too tight and can cut into the hose, actually causing the hose to be loose after several heat cycles.
Thanks. Re: Can you replace the upper radiator hose without draining coolant? You could, but it would make quite a bit of mess. You don’t need to drain all the coolant–just until the upper hose is empty.
The basic process of changing a hose is quite simple. If the hose is a radiator or heater hose, to catch the coolant and water that will run out of the system, you’ll need a bucket or pan that holds at least two gallons of liquid and will fit under the radiator drain valve (called the petcock) that drains the radiator.
When coolant near boiling passes through worn old radiator hoses, it increases the pressure in the radiator and in the hoses that connect it to the engine. Radiator hoses are designed to handle a specific amount of pressure; if that pressure increases to an excessive level, the hose will begin to swell and could burst.
Check Hoses and Connections
To check your hoses, simply squeeze them. The hoses should not collapse easily. You need to replace any hoses that are soft, rotted, or swollen. All connections should be examined to ensure they are tight.
Driving with a radiator leak is a dangerous operation, as it will very likely cause your engine to overheat. If you are driving down the road and notice your engine is overheating, pull over immediately and let the vehicle cool down.
If the upper radiator hose already gets hot before the engine has properly warmed up, it means the thermostat is not closing properly or even is constantly open. If it does not get hot at all, it means the thermostat is blocked. In both cases, the thermostat should be replaced immediately.
Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. When the engine temperature has reached the operating level, it should allow coolant to flow to the engine and regulate the heat.
Your coolant could be overheating because you have an airflow issue, but it could also be overheating if the coolant is old and need replacing. Additionally, coolant can overheat if it is not being effectively pushed through the cooling system.
The first is to drain the cooling system by removing the old hose or hoses. It is recommended to replace all cooling hoses at once since they all age at about the same rate. To remove, loosen the clamp then twist off the hose.
Will Flex Seal seal a radiator hose? A: Our customers have found many uses for Flex Tape® around their car. However, Flex Tape® is not designed to withstand extreme heat or pressure, and is not recommended for use on radiator hoses.
Determine where the radiator hose is leaking. Let the engine, hose, and radiator fluid cool for 10 to 15 minutes, even if nothing seems hot. … Tear a piece of duct tape long enough to wrap around the hose – about 4 to 6 inches long. Stick the tape on the hose, making sure to cover the hole.
Q: Can I use it on my radiator hose? A: No. We do not recommend using Flex Tape on radiator hoses.
