Toyota Agya Cooling

The Agya's 1KR-VE three-cylinder engine is modest in displacement but still demands reliable cooling to survive SA summer traffic crawls. Our toyota agya radiator and cooling-system stock covers plastic-tank alloy radiators (used R750-R1,400, new aftermarket similar), electric cooling fans with integrated motors and controllers, thermostats (82°C opening), water pumps shared with the Aygo, coolant expansion tanks, radiator caps, complete hose sets (upper and lower) and temperature sensors for the ECU temperature readout. Common failures we see in this category include cracked plastic header tanks on radiators past 10 years of age, seized fan motors from dust ingress around bushveld-area drivers, and the occasional stuck-open thermostat causing slow warm-up and poor cabin-heater performance in winter. Every used radiator is pressure-tested at 1.5 bar before listing, and Gemini Parts supplies new aftermarket units with workshop-fitment support. Coolant refill capacity is small at around 3.5 litres of long-life pre-mix, making full cooling-system service a cost-effective DIY job for weekend mechanics.
