Lightweight aluminium type high efficiency radiator with good fitment, rigidity and appearance, unlike others on the market with 4 large ugly fixing nuts on each side, or where the header tank is 10mm wider that fouls the cowlings.

Some slight fetling maybe required on radiator cowlings.

The lower hose outlet is also positioned correctly to fit the Cooper S and mini

although the radiator can foul the Pre 1973 inner wing radiator cowling without slight modification.

Water boils at 212F and when under pressure it can raise by 3 degrees for every pound of pressure. The higher the pressure cap the hotter the water has to get to boil.

Under testing the tubes can take 21 lbs pressure but the hoses etc might not. Now with 16lb rad cap.
