160 vs 180 thermostat
From the horses mouth...
Stant
THERMOSTAT TEMPERATURES
- Thermostats have a “rated” temperature such as 180F or 195F
- This is the temperature the thermostat will start to open, give or take 3 degrees
- The thermostat fully open about 15-20 degrees above its rated temperature
To be a smart-*** , nil point...I use mr. Gasket high-flow thermostat. Lol
learned this a long time ago they start opening before the rating and they're fully open by/if not 90% .
Our shop teacher was the ****, we had cut down race motors and he drove a cherry 40's plymouth special every day.
He set up the hot plate...filled it...setup a thermometer in it and dropped a 180 thermostat in.... it started popping open at 150-155 slowly...he showed us the difference between design and actual function. They dont smoothly open either...they pop in increments is what it visually looks like.
I'm not gonna argue it. I know what I've seen ..and you know what you've read.
All good. It's not gonna help going back n forth over a thermostat
