There are a lot of bad thermostats around these days, that fail after a short time or are no good when new.

I have had one fail after a year or 2, then had to put in 2 or 3 more before I got a good one.

For a 1950 car you should use a 160 for summer, a 180 for winter and a 4 pound rad cap. Check your owner's manual or repair manual for details but that was the general rule for most cars.

You can test a thermostat by heating it in a pan of water with a thermometer. Do this while your wife is not home.
