Hi Guys,
I do not have overheating  problems with my 72 vet....however for peace of mind i wanted to change the thermostat, rang the classic chev parts and they informed me that it is available in 3 options, 171,180, and 197....i am really confused, do i need to change it? as i mentioned b4 it does not overheat at all but i thought it would be a move of peace of mind....if i need to change it to which 1 should i?
What do you guys think?

cosmicvette:
If it aint broke, don't fix it!

Sorry I can't be of more help, since you don't have an overheating problem, maybe just get one as a spare? that way if your prepared, you won't ever need to change it!

Not sure which one is stock for a 1972....I have a feeling its 180?

77CVT:
180

a 170 is no big deal - just means it opens 10deg earlier.

Thunder Kiss:
One more vote for 180

TIPPA:
I've got a 180deg fitted to my "78 and she keeps her cool. If you wanted to check what your current thermostat temp is, just remove it, throw it in a saucepan full of water and watching with a thermometer heat it on the stove! When it starts opening, thats its temp setting!
Ps. since you are thinking about changing it, it must have been in there for a few years. For 20 bucks you can not only fit a new one but check out the state of your cooling system when you remove it too. Do it and fit a 180degree one and you will have cheap peace of mind!
