[DeTomaso] head drilling for air release

[Doug Braun]

Assuming your temperature gauge is working and you're in the habit of
checking your gauges as you drive, it should be quite apparent if your
thermostat fails in the open position especially if you're traveling above
40 mph.

But the only brand of T-stat I know of that has the fails-open feature is:

I've been using one of these for a few months now but it's the 351W type
without the bypass hat.  I haven't checked with them to see if they make a
351C type T-stat.

Although I agree with the sentiment, how often would you notice if one
failed to close?
