If you stand in front of your van and follow the hose on the left side of radiator- you will see another hose shaped like a C. At the bottom of that second hose is a silver therostat housing with four bolts in it. You have to empty the antifreeze and take off the two hoses to get to the housing. Rachets work best with a two inch long 12 metric fitting. Hope this is helpful.
