Why is my coolant not circulating in my Nissan Pathfinder?

Answer by  Amber40 (24961)

If it is not circulating I would guess that either you have a blockage in the system or the water pump has stopped working. If the system is block you can try replacing your thermostat and flushing the system. Making sure to purge air after refilling. If the water pump is very old it may need to be replaced.
