I am trying to find a diagram to show me where the thermostat is on my van. It needs to be replaced and I can't find anything that shows me exactly where it is. I know it is the side of the motor, possibly the left side if looking at the engine from the front. Please help. Can't afford to take it to a shop.

Hello,

The thermostat is located inside the housing on the engine. Follow the upper radiator hose from the radiator to the engine. You will see the thermostat housing is where the hose attaches to.

Simply remove the housing by taking off the mounting bolt.
