Thermostat opening temp

[falloutboy]

Hi, got a new Stant thermostat here.
Tested it in a pot - well 195° F and the Thermostat hasn't opened yet.
200° F the thermostat is beginning to open up.
208° F the water is boiling heavily the thermostat is fully open.

Is it broken or can I use it?
Thanks to heavy city traffic and stop and go my car runs at about 3/4 on the gauge.

Take it back and try another. AC delco. Actually. Stant has been going down hill lately. I put a new one in an 05 blazer and it did the same thing.

:( dang
may wanted to change to 180F and i only find Stant for the LA1

interesting thing - the stant for the nissan are dead on. well at least the made in cina one, thhe other one not so much.
yes this nissan has 2 thermostats

I forgot that I got an answer Wed 22.08
All the thermostats are tested before they leave the factory to be opening correctly.

Testing in boiling water is difficult. The best way to see if it is opening is to thread a string thru the valve and suspend the thermostat in a 50/50 coolant water solution. The thermostat will fall off the string when it starts to open. This would be at 195 +/-3 degrees. It is also hard to get a good measure of water temperature at the mid-depth area of the thermostat.

I suspect the thermostat is operating correctly

sounds like i good idea to me. give it a try.

[falloutboy]

what idea??

to test the T-stat? I already did this, not with 50/50 antifreeze (i won't ruin my cooking pots for this).

Or do you mean an 180°F t-stat?

about the 180°F T-stat
Summit says
36308
45848
13848
Stant Thermostats fit the LA1 - but according to RA they all have different dimensions

What Thermostats do you guys with a 180 have in there?

i mean with the 50/50 and string idea. having a 50/50 mix is going to change the boiling point of water. shouldnt even boil until 212F anyways. so unless your higher then mt everest 108f is not right and you should recheck your process of measuring. go buy a cheap used pot to test in if you have to.
