1973 TR 6 I replaced radiator last year did not see value in a alum one, told to stay away from China Alum. Got a OEM from VB 185deg thermostat, for cold weather in Nevada. stock fan Alum air dam to radiator. Mid grade fuel does not over heat.
I found 50/50 antifreeze added oil line to head and 185 deg. thermostat and no front lic plate and only two added grill badges no flare under bumper. No elect. fan. Fuel, tuning, oil, air flow, keep water in radiator longer, get that all right and will not over heat. I will give you AH have it harder.
