Toyota RunX Cooling

Clogged radiator cores, thermostat failures and weeping water pump seals head the RunX cooling complaint list, especially on 1ZZ-FE 160i cars that run slightly warmer under SA summer traffic. The toyota runx cooling range covers OE-spec used radiators for all three variants, water pumps, thermostat housings with gaskets, and full radiator hose kits. The 2ZZ-GE 180i RSi runs a slightly larger-capacity radiator and an uprated electric fan, which are quoted separately.

Used RunX radiators land at R520-R1,100 depending on fin condition and whether the plastic end tanks show cracking. Water pumps run R260-R620. Expansion tanks, fan shrouds, complete electric cooling fans with motors, upper and lower radiator hoses, heater cores and bleed screws are all listed individually. For high-mileage 1ZZ-FE cooling refreshes, it is worth replacing the thermostat alongside the water pump because the two fail within overlapping service windows.
