S13 240SX KA24DE Radiators and Fan Shrouds

Manual radiator: 21410-53F00 and 21410-53F10 were both replaced by 21410-53F11. Automatic radiator: 21460-53F00 -> 21460-53F01. No supersession was established for 21476-53F00, 21476-53F10, or 21477-40F00 in this pass.

Corrected scope is the factory USDM S13 KA24DE cooling layout only. Nissan catalogs assign different radiator assemblies to manual and automatic cars: 21410-53F11 manual and 21460-53F01 automatic. Dealer catalog data assigns upper shroud 21476-53F10 to cars with factory A/C and 21476-53F00 to cars without factory A/C; the lower shroud is 21477-40F00. Verify by VIN because the original EPC also carries market/equipment annotations around the upper-shroud choices. Do not apply this row to S14, JDM SR/CA engines, or swapped cooling layouts. The cited Mishimoto MMRAD-240-89KA is an S13 KA radiator documented for manual-transmission vehicles; Mishimoto directs automatic applications to add its optional MMTC-U transmission cooler. That vendor-specific instruction is not a general claim that every manual radiator is safe for an automatic car.

Checked Mishimoto MMRAD-240-89KA at $335.95 for 1989-1994 S13 KA applications, explicitly manual-transmission fitment; Mishimoto directs automatic applications to add optional cooler MMTC-U. A checked marketplace aftermarket automatic-radiator listing cross-referenced 21460-53F01 at $141. These are different buyer paths; verify transmission and engine layout.

USDM S13 KA24DE scope only. Match radiator to manual versus automatic transmission and upper shroud to factory A/C equipment; VIN-check before ordering. Mishimoto’s checked radiator is manual-transmission fitment, with an optional external cooler directed for automatic use. Swap/S14/SR fitment is excluded.
