Hi my 2001 Exterra radiator is loosing liquid and the overflow tank stays full. It won't transferr back to the rad. I can't find any leaks or sign of leaks.

Check the radiator cap (for cracks in the rubber) and the tube that goes from the radiator to the overflow tank.

Change the cap they wear out over time and will no longer hold the pressure they are supposed to and will cause cooling issues. Start there and move on if the problem persists.

Thanks just got a new cap and will try that.
