2004stratusgets hot, no leaks engine cool but no antifreeze in rad or overflow oil clean. ?????


if it over heats when stationary but cools down when moving , that is an indication of a cooling fan problem
If the engine has a viscous fan hub ( fan clutch) replace it as it is not spinning hard enough when stopped to draw air through the radiator
If it has electric fan/s check why it is not working at engine temperature --could be the coolant temperature sensor ( not gauge sender unit) that is faulty and not telling the ECM to turn on the relay for the fan/s or a bad fuse or relay that is not completing the power circuit

Fan for radiador dont work only wend a/c is turn on fans come on but slow i gat a hyundai santa fe 2002


In general, vehicles with electric radiator fans use an electronic temperature control so the fans only run as fast as needed. The energy to drive the fans come from the fuel you burn, so this is supposed to improve fuel economy. The air conditioner load makes the engine run hotter, so the fans should come on then.

Now, here is the real question: is the engine overheating at traffic light stops? Do you see an abnormal temperature rise on the dashboard gauge (assuming you have one)? If so, you may have a problem with the fan motor bearing, check for smooth and easy rotation of the fan when the engine is cold (it's dangerous to do so when the engine hot; the fan may come on even with the engine turned off). On the other hand, if the temperature indication is generally lower than it used to be, the temperature sensor may be going bad and is not calling for the fan to be on when it should be.

Mini Cooper temperature gauge goes to red zone when idle


check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling leak.so replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

Air conditioner works fine while driving. When stopped for a light, temperature gage goes up and fan blows hot air.


Hello: Check the radiator cooling fan. With engine running and A/C on open hood look down on the back-side of the grill, that's where the cooling fan is. It should be running, if not check the fuses, cooling fan relays/module if they are ok then you may have a cooling fan motor failure. You can use jumper cables to hot wire the fan motor to see if it runs.

The sensor for the fans is in the rad at the bottom. T-stat may be bad or the rad may be clogged. Cooling system needs attention.

2003 Honda Civic runs hot when idling.


Check the cooling fan switch. It appears your auxiliary electric cooling fan isn't going on when at idle. and engine temp increases. While you are driving, air is being rammed thru your radiator as you cruise along, so it isn't overheating, at idle, that isn't happening, and the fan should go on as the temp goes up. When the ac is switched on, the fan is being signaled to operate due to the heavy ac load on the cooling system.
