Basic checks
Any debris stuck between AC and radiator cores?
Fan clutch working properly?
Coolant level OK in radiator?
Fan belt tension - although serpentine belt on mn - should be OK.
Sticky thermostat?
Water pump should be fine with those kms.
Have you checked for combustion gases in coolant?
Is the temp sensor OK?
