Older truck, 360 also...

OEM cooling config worked fine...


Something else in the mix...

What would the fix be in the past???

Pre-aluminum rad availability...



Been in bumper to bumper, 95+ heat, multiple occasions...

Sometimes for hours at a time...


OEM 'air' system...

20 years of running time...

26" rad, A/C water pump, viscous, 7-blade fan, shroud...

NEVER have seen the temp beyond 180...
