Serious car overheating problem?

-My car starts fine, but after about 5 minutes of running normally the temperature gage goes from the bottom to halfway, stays there for about a minute or two, then slowly rises to above the heat line and the car says it is overheating.



This problem started after I changed a top radiator hose, but I'm positive I did it properly and it isn't leaking fluid anywhere.



The car's oil and coolant levels are both normal so that isn't the cause of this problem.



There are no other symptoms, the car isn't ejecting any smoke from the exhaust or anything like that..



Thanks in advance.check the rad reserve tank, and fill to recommended level.

hopefully any air in the system will gurgle its way out.

My windstar requires that the thermostat "jiggle valve" be positioned properly.

Valve at top.

...you may be able to bleed air, at the coolant temp sensor.
Your problem may be as simple as having some air in your cooling system.



See link to fix problem:
the coolant is not flowing through the system check hose while the car is running if it feels hard you may have a blocked radiator or a stuck thermostat good luck

First confirm that the engine is actually overheating, no heat inside, etc. Sometimes, a temperature sensor will fail and give a false reading on the indicator of overheating. For this question, at times, the meter may fail and give the same reading misleading. Make sure the fan turns on when the engine temperature begins to rise above normal. If you do not check the fan fuse, fan relay, fan sensor, the fan. Real Overheating is caused by lack of coolant and / or lack of refrigerant. Modern refrigeration systems are "closed". In other words, there should be little or no loss of coolant. If the level is too low, you have a leak .... external or internal. With the coolant at the top to the right level and the radiator cap, start the engine and check for visible leaks ... pipes, valves, internal radiator leak, for example. Head gasket is usually accompanied by white exhaust smoke, hard starting, running hard and bubbles in the expansion tank.



Sometimes, but not always, is the engine oil has a milky appearance and / or engine oil is mixed with the coolant.
