Vw Radiator Hoses---the Vein Behind the Cooling System

By: John Garett

During the circulation of the coolant through the cooling system in a Volkswagen vehicle, the artery that lets heated coolant out of the engine and return to it sans the heat is the VW Radiator Hose. As it provides a bridge function, it connects the engine and the water pump to the radiator. Coolant hoses, as generally termed, takes the form of a lower radiator hose, an upper radiator hose, heater hoses and a bypass hose for some engines. Made of flexible but reinforced synthetic rubber, they are designed to withstand heat, vibration, pressure, and cooling system chemicals. Since engine compartments for all vehicles are not the same, sizes depend on the type of engine. VW Hoses include the common hose, the molded or the shaped hose and the accordion-type of hose. These hoses have the spiral wire construction. Made of rubber with fabric reinforcement, the common hose is straight and is unable to bend before collapsing. On the other hand, the molded hoses do not collapse when bent since all the bends they need are already molded in them.

But the toughest hose is the accordion type, which has the ability to take severe bending and absorb some of the vibration between the engine and the radiator. Tough as it is, the can reach up to a stage when it can no longer endure the wear and tear during severe engine activity. It is therefore a must to have them periodically inspected at least twice a year, Be sure to check out clamp connections to ensure they are secure and free form leaks. There may be a common perception that conditions of VW Hoses may be determined from the outside. But in reality, it is detected form inside out. Called electrochemical degradation (ECD), the condition is depicted by fine crack along the surface of the wall of the hose tube. It extends from inside to the outside confines of the tube, close to one or both ends of the hose. Coolant may seep through the cracks and can even damage the hose reinforcement. It may even go worse into a pinhole leak or a burst hose. Aside from replacement, it would be better to change VW Radiator Hoses that connect to part of the cooling system that is being replaced. In attending to the cooling system, safety precautions should be taken into account. Opening a hot radiator or coolant reservoir/overflow tank can lead to severe burns. And be sure that the cooling system and the engine is cool before undergoing maintenance or repairs. Good thing VW Hoses abound even in the nearest auto parts dealerships with a barrage of makes, models years and other specifications. Over at the Internet, online auto parts retailers mushroom to address the immediate needs for VW Radiator Hoses. Plus factors would include an updated inventory on the parts, safe and fast transactions upon purchase and immediate delivery with a couple of clicks away. Cyberspace has been the most convenient venue for having a replacement VW Radiator Hose since you only have to tinker through the computer inside comfortable confines of your abode.
