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 my car’s lower radiator hose cold?
The thermostat controls how much of this cold coolant is brought into the engine from the radiator, via the lower radiator hose. If for some reason your upper radiator hose is cold, this would indicate you may have a problem. You likely have a partial water blockage in the engine passages.
What causes a radiator in a car to burst?
They may be electric fans attached directly to the radiator, or you may have one manual fan that is attached to the water pump. There are a few things that can cause a radiator to burst.
Is the bottom of the radiator hot or cold?
It may take up to 30 seconds for the thermostat to react and partially close, restricting the flow of coolant from the radiator into the engine. The bottom radiator hose should be cold, or maybe warm on very hot days.
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.
What should I do if my radiator bursts?
If you notice the water gauge getting up into the red, or if the dummy light comes on, stop immediately and shut the car off to try to prevent further overheating. The car must cool for at least one-half hour before you attempt to open the radiator cap (unless you want to get sprayed with boiling water and antifreeze).
What should I do if my radiator is overheating?
The radiator hoses should be in good shape, not cracked, brittle or leaking. Hose clamps should not be over tightened so that they cut into the hose. Other than obvious damage, hoses can restrict coolant flow. Check the routing of your hoses.
What causes a water pump radiator to burst?
They may be electric fans attached directly to the radiator, or you may have one manual fan that is attached to the water pump. There are a few things that can cause a radiator to burst. If too much pressure builds up, it can cause a weak spot in the radiator core or tank to give way.
