What is the hose that connects to the coolant reservoir?
An overflow hose connects to the radiator below the cap and the reservoir tank to store overflow of coolant. As pressures in the cooling system increase due to coolant temperatures, a valve on the radiator cap permits coolant back into the reservoir to help ease the build-up of pressure and prevent coolant loss.
Where is the upper radiator hose located?
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.

Will radiator pull coolant from reservoir?
To release pressure, the radiator cap allows some coolant to escape out, stored in the reservoir. This excess coolant stays here until the system cools down enough to create negative pressure and draw the excess coolant from the reservoir back into circulation.
What would cause upper radiator hose to burst?
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Caps are rated around 14โ16 psi. Under normal circumstances, caps should release the negative pressure caused when an engine cools down and the liquid coolant contracts.
Can you replace top radiator hose without draining?
Can you replace an upper radiator hose without draining the radiator? Yes, but it might be messy. You do not need to drain the whole radiator, only so that the level of fluid is below the level of the upper radiator hose so that the hose is empty. The radiator fluid can then be topped up.

Although considered to have a reasonable level of reliability, engine cooling system problems are fairly common in BMWs โ particularly in the case of coolant leaks and failed water pumps.
Should I replace both radiator hoses?
Coolant hoses should be replaced at least every four years, or more often as needed. It’s also a good idea to change any hoses that connect to a part of the cooling system that’s being replaced. For example, it’s wise to replace both of the radiator hoses when replacing the radiator.

Why do coolant hoses collapse?
As the pressure in the system drops โ when the engine is off and cooling down โ the pressure cap allows the excess coolant in the overflow tank to return to the radiator. If the radiator cap is malfunctioning, the vacuum created in the system will collapse the hose.
Can radiator hoses last 20 years?
There is no set lifespan for a radiator hose. On average, they should last for at least five years, but some will last longer, especially if you’re vigilant about having your coolant changed and your vehicle maintained properly.
