Radiator Hose
I have been putting water in the coolant reservoir of my 2004 Ford Explorer and because of the cold temperatures the water froze up. And now the upper radiator hose popped off and is frozen. Is my radiator damaged too? I don’t have the money to replace the engine or hose right now. What can I do?


RESPONSE
Not a good idea to put straight water in the cooling system. One, it will freeze as you are now aware. And two, the water pump bearings are no longer being lubricated. Radiator should be OK but checking for leaks once it is repaired wouldn’t hurt. You will need to thaw out the engine and drain the cooling system. Reattached the upper hose and secure it with a radiator hose clamp. Refill the cooling system with 50/50 mix coolant.
