Can a bad thermostat cause radiator hose to collapse?

If the thermostat fails in the closed position, the water pump will attempt to pull coolant from the radiator and that can cause the upper radiator hose to collapse. However, this stuck radiator condition will also cause the engine to overheat.

Can you over tighten a radiator hose?

seafish. 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. Too loose, and you’ll have a leak; too tight, and the hose clamp will damage the hose and cause premature failure.

Is it hard to squeeze upper radiator hose?

Perform a squeeze test. 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.

What will cause a radiator hose to collapse?

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.

Why does my radiator hose pop off when I turn it on?

Hello, thank you for writing in. The radiator hoses can pop off for several reasons. Typically it is because the hose or the plastic neck that connects it to the radiator/component has failed. You will want to inspect both sides of the problem hose, and determine if the clamp is doing its job.

Why is coolant building up on my radiator?

Typically it is because the hose or the plastic neck that connects it to the radiator/component has failed. You will want to inspect both sides of the problem hose, and determine if the clamp is doing its job. Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled.

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.

What should I do if my radiator is leaking coolant?

You will want to inspect both sides of the problem hose, and determine if the clamp is doing its job. Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled.

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.
