My 2010 journey is over heating what can I do to stop it
Figure out why and correct this issue. There are numerous things that can cause overheating and many are beyond the average do it yourself repair. Some possible causes are: failed thermostat, failed water pump, broken water pump belt, low coolant level, failed cooling fan, failed electrical cooling system, failed heater core, leaking hose, air pocket in cooling system, failed radiator cap, failed radiator, cracked head, cracked block, failed headgasket etc. Beware it only takes one time overheating to damage the cylinder head or headgasket. Get that checked.
