"Thermostat-less" Trans Am
Well, I can see that I have still more work ahead of me here re. the cooling of the '78...
I just returned from a roundtrip visit to the town next to us here---some 15 miles or so, away---and it is HOT outside. I stuck to the secondary highway (maximum speed = 50 mph) & the city streets, and in the stop-and-go stuff the temperature of the coolant wanted to edge just above 220F on my guage.
It crept down just a little below that marker with steady driving at 50 mph.
Next step: flush the system, then dump the Prestone "lemonade" that's in the car now, & replace it with an old-fashioned ethyl-glycol blend designed for older cars like mine...
