Having upgraded to an alloy race rad, I have my original fit Caterham radiator and SPAL fan unit for sale.
Car is a 1.8 VVC, K Series Roadsport which has done 30k miles. The radiator and fan are the original fit, but still fully functioning.
I can supply pictures if you PM me.
It is not fitted with the fan switch, as this was transferred to the new radiator.
Price £50 + postage/courier. Or I can meet you in the Bristol area if that is preferable.
