How should upper and lower radiator hoses, along with heater hoses, be checked and replaced on Volvo 740?

Upper and lower radiator hoses, as well as heater hoses, should be inspected for deterioration, leaks and loose clamps at least every 15,000 miles (24,000 km) - periodic inspections are recommended during the early spring and at the start of fall or winter during other maintenance. A quick visual inspection can show weakened hoses that can result in breakdowns if they are left in place. When checking hoses, ensure that the engine and cooling system are cold and look for any cracks, rot or collapse; replace those with weak or swollen spots. Start by disconnecting the negative battery cable and stripping the radiator pressure cap, being careful not to get burned by hot coolant or steam. Position a clean container under the radiator and open the drain to allow the cooling system to drain appropriately, considering that pets may have an affinity for antifreeze, which may be fatal. Loosen the hose clamps on both ends of the hose to be replaced, twist, pull and slide the hose off the fitting without damaging the connection. If the hose is stuck, use a single edged razor blade to make a cut down the stuck portion without cutting too deep. Clean both hose mounting connections and look at the clamps for replacement if necessary. For installation, dip the ends on the new hose in clean engine coolant, slip the clamps over the replacement hose and secure them at least 4 inches (6.35mm) from the ends of the replacement hose making sure they are past the raised bead of the connector. Close the radiator or engine drains and fill the cooling system with clean drained coolant or a suitable combination of ethylene glycol and water. If available, install a pressure tester to check for leaks and if not, run the engine to normal operating temperature and then check for leaks around the hose fittings and connections, being extremely careful around moving or hot engine parts.
