Spitfire Radiators Original Specification Summary Early Mk1’s (to FC39925) had a 22” wide radiator (with 2 top hose connections) and a separate (steel) remote header tank with a 7lb pressure cap. Because of ‘over cooling’ the header tank was removed at FC39926 and a new radiator (still 22” wide) but with only 1 top hose connection was used. The overflow pipe now came from the pressure cap neck on the radiator and fed into a plastic overflow bottle located in front of the radiator. The same cooling system - 22” wide radiator with a 7lb pressure cap - was used for all Mk2’s. All Mk3’s were produced with a 16” wide radiator fitted with side extensions (allowing the same Mk1/Mk2 mounting cradle to be used). Mk3’s from FD48653 had a more efficient 16” radiator with a 13lb pressure cap. The MkIV & 1500 retained the 16” radiator and 13lb pressure cap. Replacement Radiators We supply New and Reconditioned 16” radiators (recon’ fitted with new core), and New 22” radiators. Important Note With the exception of very early Mk1’s (with 2 top hose connections & separate header tank), our 22” full width radiators are suitable for ALL models (except late USA vehicles) with correct pressure cap. Late USA spec vehicles from FM95001. Although late USA models were originally fitted with a 22” wide radiator, they CANNOT be interchanged with a UK spec’ 22” radiator as the 13lb pressure (filler) cap for USA vehicles is located on the Water Pump/ Thermostat Housing, NOT on the radiator.
