Strange cooling behavior at 0F ambient

[Konstantin Bogach]

I have two 200tq '89,  one is MC1 and another is MC2,  not that it 
matters,  and one warms up quicker and to normal temp and another stays 
at 1/4 and warms up slower.
If the latter idles long and  I do city driving then it can reach normal 
temp at 1/2.  Otherwise it stays at 1/4 and fan never comes up.  Oil 
temp is also lower than on another car.
I think it is bad termostat and taking into account that I am not alone 
it looks like, if I am right, that teromstats have pretty high rate of 
failure.  Mine is new,  15Kmi,  by th way.
