Depending on motor selection in almost every care with a 6 Cyl, the original radiator will more than adequately cool the
car. Providing adequate clearance can be obtained for a decent fan even the large red motors will work well, if the radiator
is in good condition.
Later radiators FE-EK although being shorter will still fit and work well. EJ onwards require widening at the sub frame
area and are not as large a capacity as FX-FJ.
Cross flow Commodore mounted vertical fit well, requiring no sub frame work and will cool the largest of the V8s and handle
all 6s with air conditioning, but they are approx 4 inches longer than FJ and do not fit as well as original.
