Toronado thermostat
#4
1st gen Toronados tend to run quite hot underhood. I'd use a 180 high flow like a Robertshaw (which incidentally Olds switched to in the early 70s in lieu of the Dole flapper units they'd used for years). The 160 will stay wide open all the time trying to maintain temp and a 195 will be good for cold warmup, but may cause some overheating issues in traffic.
Having a properly functioning clutch fan and all radiator seals and air dams in place is crtitical on a 1st gen Toro.
