6-12. Hose Collapse. When the rubber in the coolant hoses starts to deteriorate It becomes soft

and has a spongy feeling. Overheating problems that occur only at high engine speeds are normally

from a deteriorated hose on the suction side of the water pump collapsing. The hose can be reinforced

by inserting a rigid hollow object, like a can or wire coiled, to prevent the hose from collapsing.

The inserted item will help the hose remain open even though the suction is trying to close it.
