Toyota Quantum Cooling

Cooling is a stress point on the Quantum — high-idle taxi service in JHB traffic, combined with heavy passenger loads climbing the Reef escarpment, pushes the cooling system to its limits. Our toyota quantum cooling stock covers radiators, water pumps, thermostats, radiator fans, radiator hoses, expansion tanks, and heater cores for every H200 variant. Fleet operators ordering in volume get wholesale pricing on radiators and water pumps from the JHB depot.

Radiator failure on high-mileage taxi-spec Quantums typically comes from plastic tank cracking at the top seam — a pressure-test confirms the fault before replacement. New aftermarket radiators for the 2KD-FTV run R2,400-R4,200 from the JHB depot; used OEM pulls from CPT donors at R1,200-R2,200 pressure-tested. Water pumps fail at 150,000-250,000 km and should be replaced with the timing belt service on the 2KD-FTV. Radiator fan clutches on the 2TR-FE petrol commonly fail the bimetal spring at high mileage — simple test, cheap fix if caught early.
