Thermostates A have 2 barrel type thermostats for use in a 36 ford. I teasted them in water. One has a tight seal and opened up at about 175. The other does not seem to close tight and fully opened at about 165. Am I right to say that the thermostat that does not close tight and is not good.

engine and take a long time to open. When a small amount of coolant flows through at startup warm coolant opens the stat faster. Has nothing to do with the operation of the stat after it is open. G.M. |

Re: Thermostates If you don't care how fast the engine warms up or whether it ever actually does you can use a faulty thermostat that doesn't close all the way. But, if you ever need the heater, like I did last night when it was 6°, you'll have a hard time getting enough heat out of the heater if the thermostat doesn't close all the way. Stock thermostats that have a bleeder hole have a stopper in that hole that stops all flow when water is pushed against it. Any flow through a thermostat when it is supposed to be totally closed reduces it's effectiveness.

Re: Thermostates My thermostats each have a small hole (1/16) drill size, and NO stopper in the hole.
You need a small bleed hole in the stat, so when you fill it with coolant, the trapped air can bleed out of the engine, the coolant can fill the block and heads completely. . |

Re: Thermostates This gap is 1/16" you can fill in the spring that one has more tension on it then the other.

Re: Thermostates I didn't realize you had the option to return it! If that is the case that is what I would do.

Re: Thermostates Thank you for all the help. This is a great place for information
