I have the same problem. I unpluged the fan and ran the van with the rad cap off . Kept squessing the rad hose until the thermostate opened more. I still have not changed it. Its about a 4 hour job. Montana's have are in such a great spot, as you know. My temperature guage is running at about 1/4 when it should be up at 3/4.

If you mean that the brakes are locking, then check brakes calibration and brakes fluid level.
If the engine is failing or stopping try to understand if it is a distribution or a fuel problem.
If it always happens at same gauge and speed it is probably something related to the electronic injection module. Best thing to do is going to a garage and having ECM (electronic control module) scanned, this will return error codes that can tell you what the problem is.

1- o/d light is transmission issue- if miles in excess of 135000- change fluid and filter and cross fingers- known issue with windstars
2 unsure of wiring for 02 sensor - sorry
3 - windstars have a leakage problem at intake that throws lots of codes dealing with injectors/o2- dealer kit to replace o-rings,gaskets,bolts and valve cover to correct
4- lots of revs with no go - either tranmission issue-see 1 or catalydic converter melted/plugged

Check to see if the radiator fan is coming on when the van gets hot.If it does not then on a 2.6 liter engine.look on the bottom part of the radiator on drivers side for a fan switch that could be bad and not letting the radiator fan to come on. On a 3.0 liter engine the coolant temperature sensor is screwed into the thermostat housing. And on a 3.3 liter and on a 3.8 liter engine the coolant temperature sensor is screwed into the front cylinder head. Anyone of these can cause the van to run hot and eventually die with no restart until the temperature has cooled down. Check the fan first with two jumper wires from the positive/negative post to the fan connector on a 2.6 liter engine (positive wire to open pin on plug,negative wire to insulated plug side. On all v6 engines hook jumper wires to motor. To the left side will be positive and negative to the right. Do not let both wires touch together while testing. If motor does not respond to direct wiring then replace it. Another thing to look at is the catalytic converter on van. Check the exhaust flow when the van is running cold and again when it gets hot. If the flow starts to slow down when the van gets hot then remove the converter(plugging up). After doing that run the van again to see if the van runs ok. Hope this will help you.
