2005 Dodge Dakota Owner Manual - Page 317

MAINTAINING YOUR VEHICLE 317 attention should be given to examining hose surfaces nearest to high heat sources, such as the exhaust manifold. Insure nylon tubing in these areas has not melted or collapsed. Inspect all hose clamps and couplings to make sure they are secure and no leaks are present. You are urged to use only the manufacturer's specified hoses and clamps, or their equivalent in material and specification, in any fuel system servicing. It is mandatory to replace all clamps that have been loosened or removed during service. Care should be taken in installing new clamps to insure they are properly torqued. Positive Crankcase Ventilation (PCV) Valve Proper operation of the crankcase ventilation system requires that the PCV valve be free of sticking or plugging because of deposits. Deposits can accumulate in the PCV valve and passage with increasing mileage. Have the PCV valve, hoses, and passages checked for proper operation at the intervals specified. If the valve is plugged or sticking, replace with a new valve - Do not attempt to clean the oil PCV valve! Check ventilating hose for indication of damage or plugging with deposits. Replace if necessary. 7
