location of thermstat

The temp guage in my 2001 Grand Caravan EX does not want to come off from the cold mark. If I shut the van off after it has warmed up, then the temp gauge comes up to the quarter mark. I live in Minnesota so obviously heat is important these days. Could someone tell me where the thermostat is located and I will replace that and see what happens. Thanks!

Follow the big hose that goes out at the top of your rad. Where it goes into the block, the therm. stat should be right in there.
