DODGE DURANGO THERMOSTAT PROBLEM

1999 Dodge Durango • 172,500 miles

Engine doesn't heat up to temp enough to get heat on the highway. If I stop for a few min. It will start to heat then drops after I start moving. When idiling it heats slowly.

Try replacing the thermostat and see what happens and also check water pump operation-

Is the thermostat below the large radiator hose connected to the top of the block, middle passenger side?
