Determine what caused the problem

The first thing that may warn you about a problem is an overflow from the reservoir or leakage from the radiator. Try to recollect the things that took place in the previous twenty-four hours before the collapse to get a general idea about the section you need to work on. Check the radiator and nearby parts of the engine.

Add water

Add about two caps of water into the radiator and warm up the engine to see whether the radiator hose may get back to normal. Ensure that the car remains stationary, and the hose does not become disconnected.

Try to solve the problem

With the engine running, check the radiator to determine the problem. You may notice that the hose does not have sufficient strength to be attached to the radiator. The coolant system may also develop some vacuum, leading to the collapse.

Replace the collapsed hose

You will need to remove the clamps that attach the hose to the radiator. You should, therefore, know how you should remove the clamps, especially considering that different automobiles use different radiator hose clamps. You should know the various clamps and how to remove them.

Know the clamps used

Determine the radiator hose clamps used in your vehicle. Check the way they attach to the hose. Crimping clamps simply connect to the hose while band clamps use a screw to attach to the hose. You need to unscrew band clamps and remove the hose without eliminating them. However, you will need to remove the crimping hoses after removing the tube.

Drain the antifreeze

Drain off antifreeze or coolant from the radiator before you remove the clamps. Place the drain pan under the radiator and open the petcock valve with a wrench, ensuring that you empty the heater completely. Close the petcock valve after that.

Remove the crimping clamp

Hold the clamp’s vertical bars closed using pliers so that the clamp becomes loose.

Loosen the band clamp

Turn the clamp’s screwdriver in a counterclockwise direction using a screwdriver slowly to loosen the clamp. Lift the clamp out using your hand.
