A) Wait for the engine to cool off, open the hood and locate the source of the steam.
B) Clean and dry the area around the fissure, the tape won’t stick on damp and dirty surfaces.
C) Wrap two to three in. of duct tape around the hole and press firmly.
D) Over wrap the patch ( the hose will be under intense pressure) from 2-3 in. above the original piece to about 2 or three in. then work your way back.
E) Check your radiator level before cranking the engine. If it is seriously low and you don’t have a can of coolant use water, or in case of an emergency, diet soda. Avoid using fruit juice or anything with sugar or acids in it, it will corrode the radiator and hoses.
