That's how a T'Stat works. It open to let the cooler water cycle through
the block and then closes when it's cool enough. Cold weather isn't an
issue since the water will heat up in the block regardless.

Subject: DML: Thermostat question
Are the thermostats on our trucks (97, 318 for example) constantly opening
and closing, when at normal operating temperature? I noticed mine will heat
up first thing, then it opens when warmed and then it drops (when the
thermostat first opens of course), noticeable on the temp gauge. And after
that it is constantly up and down, not by much but noticeable on the gauge.
I know a lot of you are saying "change that damn stock 195 out to a 180" but
it is cold here in BC, Canada, so later in the spring I will.
Thanks for any advice,
Jay
