check radiator for small leaks or cooling lines which would most definitely cause it 2 steam when running after awhile
If the electric cooling fan(s) are not coming on that may be the problem.
Hey Willie==If it comes out the cap and not the overflow jug, the cap is faulty plus what is causing it to get hot. 'Check the fans for proper operation. If it isn't smoking white smoke, it probably isn't the head gaskets. A stuck thermostat will also cause it ot overheat. If all else fails, take it to a radiator shop and have the radiator flow tested. GoodluckJoe
At the radiator or overflow tank. Do not add water, add coolant.
During radiation, energy is emitted from a source and propagated through the surrounding medium, or the energy involved in this process.
have you flushed your radiator or changed the thermostat it could be stuck
check your coolant if it low refill it. check your coolant bottle and radiator for leaks if all is still over heating..sell it you have blown heads
Do not take a radiator cap off. Fill from the overflow tank or you will add air to the cooling system and it will have to be bled off or your engine will overheat.
your radiator clogged up.cheaper to get a new radiator. nothing to do with the radiator cap.
One situation that the overflow jug would cause an overheat condition would be if the hose and/or connectors were plugged up or blocked. NOTE: before disconnecting anything to do with the radiator, ensure the engine is COOL! The cooling system operates under significant pressure.
I was having the same problem with my 99 explorer. What I discovered was that the overflow tank for the radiator was empty and was causing a false reading by the temp gauge.
Blown head gasket or bad radiator cap
Check the upper and lower radiator hoses at the engine. They have a tendency to expand and split.
The heater core has no overflow hose. Cooling system is a closed loop system and the only overflow hose is the one going from the radiator cap to the reservoir. A thermostat that is stuck closed will cause the engine to overheat. Drain and flush the radiator, replace the thermostat, install a 50/50 mix of antifreeze and distilled water, bleed air from the system. You may also need to replace the radiator cap. Be sure and replace these parts with OEM parts.The heater core has no overflow hose.

Bad radiator fluid.
if its at the front, radiator or hose, if its closer to the tire could be overflow tank or cap.
Check coolant level Replace radiator cap Radiator may be clogged Make sure air flow through radiator is not resitricted
Filling the overflow to the correct level will suffice as the radiator will draw out what it needs.
