Approximate capacity of this alloy radiator is 1 1/2 quarts C-ARA5000 ALLOY RADIATOR FITMENT Made specifically for pre 1990 cars it has however been fitted to later cars and has a drain plug which is the same size as the screw in type sender unit as fitted to all later cars.(See C-ARA5000 sender unit) The header tank on this radiator is 10mm wider than standard biased towards the inner wing and on post 1990 cars where the engine is ½" further forward fitting is not straight forward, but has been achieved by competent car Mechanic/engineers. Please do not attempt to fit this radiator to 1275cc post 1990 cars unless prepared to make modifications, as the fins will get damaged making it non-returnable. CHECK BEFORE FITTING Take the cowling from the engine and make sure it fits the radiator easily and file out mounting bolt holes if necessary, which makes life easier when fitting in the car. Make sure you fit short metric cowling to radiator bolts. Place cowling in position loosely but do not attach until the radiator has been dropped in place and checked for fitment.(then fit to cowl). Ensure the front of the radiator where the top hose fits clears the lip of the wing to avoid damage. You may have to cut the tab from the boomerang shaped upper radiator bracket that sits against the thermostat housing, to allow movement and modification to squeeze the top tank in . Make sure the fan clears cowling all round. The variants that make this radiator difficult to fit on post 1990 cars is that the engine is further forward and the subframe mountings might have wrong alignment. The engine mountings available also play a critical part in alignment as well as any previous accident damage repairs.
