Hi I ca see that you asked this question a long time ago.Lets hope you already have the answer but just incase you do noti will tell you where the thermostat is.it is connected to the LOWER RAD HOSE not the upper like one would think you will need to take out the alternator it would probably be a bit easyer to do it all from under the van when you take out the alternator disconnect the battery. that alternator is $200+ so you don't wan't to short it outand while you are at it make sure no oil is leaking from the Power Steering hose that too can bake your alternator oil is bad for alternator. the thermostat is located behinde the alternator just follow the lower rad hose. have fun that's not the best thermostat to replace.good luck

Look where the upper radiator hose connects to the engine. There you will find the thermostat.
Follow the top radiator hose to the engine, the thermostat is at the end of it.
The thermostat is under the housing where the lower radiator hose attaches to the engine.
Remove the top radiator hose. The thermostat is located under the hose inlet on the engine. Remove the inlet to replace the thermostat.
