Can a bad radiator hose cause engine damage?
In other cases a cooling system fault can cause the hose to collapse. In either case an inspection must be performed as a coolant hose that has collapsed cannot flow coolant properly. This can result in the vehicle overheating and engine damage. 5. Radiator hose is broken
Where does the radiator hose attach to the engine?
The upper hose attaches from the top of the radiator to the top of the engine at the thermostat housing. The lower hose attaches from the bottom of the radiator to the water pump of the engine. If you suspect either radiator hose is failing, watch for the following symptoms:

When to close the radiator thermostat when not running?
The thermostat should be closed when the engine is cold and not running. Regulation of water by the thermostat prevents engine hot spots. Once the optimal temperature has been reached, the coolant water will be let into the radiator for energy dissipation.
