Visual Inspection

Procedure

If the cooling system problem is not caused by a driving condition, perform a visual inspection to determine if there was a recent service or accident repair, including the following:
^ Loose/damaged water pump drive belt
^ Incorrect cooling system refilling (trapped air or low level)
^ Brakes possibly dragging
^ Damaged hoses
^ Loose/damaged hose clamps
^ Damaged/incorrect engine thermostat
^ Damaged cooling fan motor, fan blade and fan shroud
^ Damaged head gasket
^ Damaged water pump
^ Damaged radiator
^ Damaged coolant recovery system
^ Damaged heater core
^ Open/shorted electrical circuits
If the visual inspection reveals none of the above as cause for a cooling system complaint, refer to the Diagnostic Charts.
