Radiator Core Deterioration
Symptoms
Overheating, particularly in traffic. Coolant leaks from the radiator core or tank seams. Discoloured or contaminated coolant.
Cause
The original brass/copper radiator loses efficiency as internal passages corrode and block. The solder joints between the core tubes and header tanks weaken with thermal cycling.
Fix
Replace with a larger-capacity aluminium radiator ($300-500). The aluminium upgrade provides significantly better cooling in Australian conditions and is one of the most worthwhile modifications for any 2002.
