Overheating
Symptoms
Temperature gauge climbs in traffic or on hot days. Coolant loss through overflow.
Cause
The A-series cooling system is marginal in Australian conditions. The original radiator loses capacity with age. The thermostat sticks. The water pump weeps.
Fix
Replace the radiator (aluminium upgrade $200--400), thermostat ($15--25), water pump ($40--80), and all hoses. Total cooling system refresh: $250--500.
