the radiator or hoses.

cold start. Confirm that the fans are operating by checking the fan sound and air
flow. If it is difficult to check these, turn the air conditioning system on and off
repeatedly.

dealer or repairer, or another duly qualified and equipped professional.

repairer, or another duly qualified and equipped professional.
