Ford 5S4Z-18472-AA Hose Heater Water

Refer to the warnings given before starting work. If the checks reveal a faulty hose, it must be replaced as follows. First drain the cooling system; if the coolant is not due for replacement, the drained coolant may be re-used, if it is collected in a clean container. To disconnect any hose, use a pair of pliers to release the spring clamps (or a screwdriver to loosen screw-type clamps), then move them along the hose clear of the union. Carefully work the hose off its fittings. The hoses can be removed with relative ease when new - on an older car, they may have stuck. If a hose proves stubborn, try to release it by rotating it on its fittings before attempting to work it off. Gently pry the end of the hose with a blunt instrument (such as a flat-bladed screwdriver), but do not apply too much force, and take care not to damage the pipe fittings or hoses. Note in particular that the radiator hose fittings are fragile; do not use excessive force when attempting to remove the hoses. If all else fails, cut the hose with a sharp knife, then slit it so that it can be peeled off in two pieces. While expensive, this is preferable to buying a new radiator. Check first, however, that a new hose is readily available. When installing a hose, first slide the clamps onto the hose, then work the hose onto its unions. If the hose is stiff, use soap as a lubricant, or soften it by soaking it in boiling water, but take care to prevent scalding. Work each hose end fully onto its fitting, then check that the hose is settled correctly and is properly routed. Slide each clip along the hose until it is behind the flared end of the fitting, before tightening it securely. Refill the system with coolant. Check carefully for leaks as soon as possible after disturbing any part of the cooling system.
