Overheating 2003 dodge durango. What could be the problem??

When engine running, ensure no engine combustion gas bubbles in coolant resevoir (if so, the head gasket is blown).

Check cooling fans are operating ok (when required when car warms up), if not check
1) fuse,
2) relay operation,
3) heat sensor switch.

Replace thermostat.
When re-filling cooling system, bleed off any airlock as necessary.

Check for collapsing (soft) coolant hose on suction side of waterpump when engine revs above idle.
