i am fitting a 240sx single row radiator thats ring not a double or more.
i removed the water pump and the thermostic fanclutch assembley
got a pump clutch assebly thats the way it comes ,with the needed adapter to go from static clutch to non static why lighter clutch no therstat to get stuck or fail. longer lasting water pump.they said the fan gkteck will only fit the 240sx and sylvia and does fit 210 510 maybee the z cars too 5.25 thermostatic fan clutch fits awsome wonder boy drifters cars, and our old econo japmobiles too :-)anyhow my shroud is smaller but i am using a 240 rad n shround hoses the . cost $300
i then got 1 wrong fan,the gkteck propellor fan 60% more air same lightweight $100 plus each. it works really well then the added trans coolor and the R12 condensor for a cool datsun in hotbama
