The cooling system is sealed when the radiator cap is tightened in place. Coolant expands when it is heated and contracts when it is cooled. When a closed system contains fluid that experiences expansion, the excess fluid needs to go somewhere. In a cooling system, the coolant is pushed into a reservoir known as a surge tank. The surge tank hose connects the tank to the radiator where the fluid comes from. When the engine is hot, the pressure builds in the radiator and some fluid pushes past the radiator cap seal to the overflow or surge tank hose. When the engine cools down, the fluid is drawn back into the system by vacuum that is created from its contraction. If the surge tank hose is cracked, broken or deteriorated, it should be replaced.
The surge tank hose is rubber and may need to be changed due to cracking or deterioration. If your surge tank hose begins to leak coolant, have one of our expert mechanics replace the hose.
The cooling system operates as a whole. If one part doesn’t function as it should, the whole system is compromised. A leaking surge tank hose can draw air into the engine, causing an overheating condition which is damaging to engine components. Have a leaking surge tank hose replaced as soon as it is noted.
