newell had one company make all the radiators and charge air coolers. they had done the calcuations to supposedly have enough cooling.
i think on the series 60's coaches it is adequate. i do know they made two sizes of radiators for the 8v92 coaches. one just a little bigger than the other.
the challenge with the 9v92 coaches to me is the rear radiator and that on most all of them it was a direct drive fan. that is why you have to gear down going up a hill when you slow down so as to keep the rpms up on the fan. the series 60 has a two speed fan and is hydraulically controlled. i also know some have retrofitted the 8v92 engines to a clutch type fan. i think wally did this if i remember right.
