What happens when the radiator hose is broken?
Radiator hose is broken The radiator hose is part of your vehicle’s cooling system. The hose carries the coolant to the radiator, where the fluid is cooled, then back to the engine to keep the vehicle from overheating. This allows your vehicle to operate at the optimal temperature and prevents the engine from getting to hot or cold.
Where are the radiator hoses located on a car?
The upper radiator hose runs from the radiator to the motor. You can usually see most of this hose. The lower radiator hose is harder to find. To locate it, get underneath the car and look for a smaller diameter hose leading from the radiator into the heat wall of the car. Visually inspect each radiator hose.
How can I tell if my radiator hose is in good condition?
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. Check the clamps that connect the hose to the radiator and the engine.
Why are radiator hoses overlooked during routine car inspection?
One reason radiator hoses are overlooked during a routine car inspection is that the hoses can be difficult to reach. The upper radiator hose runs from the radiator to the motor. You can usually see most of this hose. The lower radiator hose is harder to find.

Where does the radiator hose attach to the engine?
The upper hose attaches from the top of the radiator to the top of the engine at the thermostat housing. The lower hose attaches from the bottom of the radiator to the water pump of the engine. If you suspect either radiator hose is failing, watch for the following symptoms:
Can a low coolant light cause a radiator hose leak?
If your Low Coolant Light comes on, or you are having to constantly replenish the fluid, there could be a leak in the radiator hose. This type of leak should be visible as drips where the vehicle was parked.
Where does the water pump connect to the radiator?
There are two hoses that connect to the radiator. The upper hose attaches from the top of the radiator to the top of the engine at the thermostat housing. The lower hose attaches from the bottom of the radiator to the water pump of the engine. If you suspect either radiator hose is failing, watch for the following symptoms: 1. Leaking coolant
How does the overflow hose in a radiator work?
An overflow hose runs between the radiator cap and the reservoir tank where extra coolant is stored (and added). As pressures within the cooling system change with coolant temperature, a valve in the radiator cap allows coolant to flow back into the reservoir to relieve pressure buildup which naturally occurs.
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.
What does it mean when your radiator hose pops off?
The hose fits on it snugly and clamps down tight. I would pressure test the system to see when this hose pops off. If it pops off at a pressure below what the cap is rated, then it’s not clamping tight enough. If it pops off above what the cap is rated for, then the problem would be the cap.

Why does upper radiator hose keep building up pressure?
Q: Upper radiator hose keeps building up a lot of pressure and popping off. Car loses coolant and over heats. My upper radiator hose keeps building alit of pressure and popping off and car loses coolant and overheats. I changed radiator cap after reading that could be problem. My car has 191400 miles. Hello, thank you for writing in.
Why is the water coming from the top of the radiator?
Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled. The water pump is what pushes it through the thermostat, and if you have excessive pressure, you will want to direct your attention there.
How to get the top radiator hose to be hot?
1 Remove the splash tray and push the coolant catch tray in. 2 Remove the thermostat cap, usually on the top hose at the engine. 3 Clean the stat seat on the engine and cap. 4 Lube the new stat seal with fresh coolant and fit it, check the orientation (Jiggle valve up). 5 Tighten down the cap bolts and torque to approx 10Nm (89in lbs).
Why is my radiator hose warm after a cold start?
If the top and bottom radiator hose are equally warm after a cold start. The thermostat is likely stuck in the open position. John Cunningham is an Automotive Technician and writer on Rustyautos.com.
Can a SAE hose be used under the hood?
Worse yet, the in-tank hose (SAE J30R10) can’t be used under the hood, either, because its outer covering can’t stand up to the underhood environment. And, of course, the SAE also has specs for other fuel lines, like J30R7 and J30R8, each different from, and incompatible in some way with every other!
What do you need to know about radiator hoses?
This article will tell you what you need to know about selecting the right hose for any given application. Let’s start with the basics. Molded hoses are used for many applications such as radiator, heater and other cooling system hoses.
What’s the rating on a zinc hose Mender?
Review Rating Choose a Rating Orbit5/8 in. – 3/4 in. Zinc Male Hose Mender (797) Model# 56687 Orbit5/8 in. Metal Female Mender (111) Model# 27989 Orbit5/8 in. Metal Male Mender
Can a silicone heater hose be used as a bulk hose?
According to every manufacturer I contacted, this is strictly prohibited. Even silicone heater hose, widely—although incorrectly—considered the most chemically resistant bulk hose available, is a very poor choice for such an application. You really need a hose specifically designed for this sort of use.
Can a bad heater core cause your car to overheat?
Can a Bad Heater Core Cause Overheating? Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle’s cooling system.
What happens if your car overheats and dies?
Overheating can warp the cylinder head and/or engine block, which can cause a failure to start due to loss of compression, valve damage and so forth.
What to do if your car heater is leaking?
Detach and remove your heater and air conditioner controls. Unbolt and remove the dashboard. Do not disconnect your air conditioning unless it’s absolutely necessary and only if you have the proper means to dispose of the Freon. Do not just let it leak into the air.
What to do if your car heater hose is broken?
Don’t cowboy the hoses; they may be fragile and in need of replacement. Add water to your reservoir or radiator, or drive (no longer than 10 minutes!) to the nearest place you can get coolant. This fix isn’t permanent, so make an appointment to have your hoses and coolant checked.
What happens when an old heater hose ruptures?
Old hoses can break down, weaken, and eventually rupture and leak. A leaking heater hose will not only produce a coolant leak that may leave puddles of coolant under the vehicle.
What causes a car heater hose to blow out?
The telltale signs of a blown hose will be coolant splashed over the engine and under the hood. This alone doesn’t mean you have a blown hose, however. It could be a faulty thermostat that caused the radiator cap to release.
Where is the hose on a car heater?
Carefully examine the hose from the water pump back to the heater core inlet and outlet near the firewall (backside of the engine compartment). The leak may be at a fitting on the water pump or even at the heater core.
