TITLE: Collapsed Upper Radiator Hose

APPLIES TO: 2003-05 Lancer, Outlander

SERVICE TIP:






If the radiator cap's vacuum valve is stuck closed from corrosion, it may cause the upper radiator hose to collapse. Change the coolant and replace the radiator cap. Do not replace the thermostat for a collapsed hose.
