What you need to know
Confirm V35 Coupe body, VQ35DE, VIN/build, five-speed automatic versus six-speed manual and exact installed fan-assembly number. The automatic radiator carries transmission-fluid cooler provisions that the manual branch does not establish; aftermarket consolidation does not prove the two OEM radiators interchangeable. The early and later complete-fan catalogs overlap for 2005-2006 Sport/Track cars, so do not impose a guessed year cutoff. Test fan command, fuses/relays, wiring/connectors, obstruction and both motors before replacement. Work only on a cold engine; never open a hot pressurized cooling system. Follow current Infiniti procedures for draining, correct coolant handling, refill/air bleeding and leak/temperature checks. Radiator, fan/shroud assembly, individual blades/motors, cap, hoses, reservoir, mounts, hardware, coolant, condenser and transmission-cooler hoses are separate unless a listing expressly includes them.
OEM numbers
G35 Coupe VQ35DE radiator: six-speed manual 21410-AM900five-speed automatic 21460-AM900. Complete motor/fan/shroud families: 21481-CD000 -> 21481-CF40B for the checked 2003-2006 Basic/Sport/Track branch21481-CD00A21481-CM30A -> 21481-CM30B for the checked 2005-2007 Sport/Track branch. The cataloged complete-assembly families overlap in 2005-2006, so VIN/build/equipment and the installed number must decideyear alone is insufficient.Supersession
Checked same-family chains are 21481-CD000 -> 21481-CF40B and 21481-CD00A / 21481-CM30A -> 21481-CM30B. No radiator supersession is asserted between manual 21410-AM900 and automatic 21460-AM900; they are transmission-specific branches. No interchange is asserted between the two overlapping fan families without exact installed-number confirmation.
Fitment
Confirm V35 Coupe body, VQ35DE, VIN/build, five-speed automatic versus six-speed manual and exact installed fan-assembly number. The automatic radiator carries transmission-fluid cooler provisions that the manual branch does not establish; aftermarket consolidation does not prove the two OEM radiators interchangeable. The early and later complete-fan catalogs overlap for 2005-2006 Sport/Track cars, so do not impose a guessed year cutoff. Test fan command, fuses/relays, wiring/connectors, obstruction and both motors before replacement. Work only on a cold engine; never open a hot pressurized cooling system. Follow current Infiniti procedures for draining, correct coolant handling, refill/air bleeding and leak/temperature checks. Radiator, fan/shroud assembly, individual blades/motors, cap, hoses, reservoir, mounts, hardware, coolant, condenser and transmission-cooler hoses are separate unless a listing expressly includes them.
Aftermarket options
Checked replacement paths include an automatic-style radiator with cooler fittings and complete electric fan/shroud assemblies cross-referencing 21481-CF40B/CD000. Match transmission, cooler ports, dimensions, connector count, motor/blade orientation and shroud geometry. A seller's combined 350Z/G35 or manual/automatic fitment is catalog language, not proof of every OEM branch or installed assembly interchange.
Before you buy
US/LHD 2003-2007 V35 G35 Coupe VQ35DE only; every sedan, G35x/AWD and V36/G37 is excluded. 350Z fitment is outside this page: 21481-CD000/CF40B is a verified shared exact-number fan branch, but no other 350Z/G35 interchange is inferred. Match radiator to five-speed automatic versus six-speed manual and verify cooler provisions. Complete fan families overlap in checked 2005-2006 catalogs, so use VIN/build/equipment and the installed number rather than a guessed year split. Diagnose fan command, wiring and both motors first. Work cold; never open a hot pressurized cooling system, and follow current Infiniti coolant/refill/air-bleeding procedures. Radiator and fan/shroud are separate; cap, hoses, reservoir, mounts, hardware, coolant, condenser and cooler hoses are not assumed included. Seller states are dated observations.
