Coolant fan not working- engine staying too hot

After I drive my car for 15-30 minutes, the engine gets really hot. The temperature gauge does not venture past the middle, however the engine feels hot for hours after it is turned off. The fan does not come on.

    My 1988 626 turbo is getting very hot in stop and go traffic. Ok with normal driving. The radiator fan does not seem to be coming on. Turning the a/c on does not turn fan on either.

The fan might not be working because the sensor in the radiator could be bad.

Is it normal for coolant bottle to boil?

No it is not. Is your engine running hot according to temperature gauge? That is the coolant return which means the coolant was too hot coming out of engine and returning to rad for cooling. You obviously have a cooling system problem whether water pump, thermostat, rad, cooling fan etc. Give more details on what happens when starting from cool, and sittting idling, driving etc as far as temperature gauge reads and how hot engine gets. Be careful not to overheat engine, if you haven't already

Is it normal on 94 grand prix 3.1 for the temp. gauge to NOT stay at a steady temp. all the time? mine seems to go up to 210 at a stop light then go back down after i start rollin again, i just had air...

Have you checked your cooling fan to see if it is working propely? Let the car idle and get warm and listen for the fan to kick in (if they are electric) or just watch to see if the fan starts to spin faster if it is the old school type with a clutch. Have you replaced the thermostat? A bad one will let the temp rise since it opens too late and then the temp will drop off. But it won't due this only at a light and it will do it infrequently.

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 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.

My car is getting hot in idle, what is wrong?

Check first your coolant level. Start engine and turn on ac open hood see if cooling fans are running, if fans are running and coolant level is ok temperature should stay normal. If temperature rises squeeze coolant hose, it should be firm like you could feel pressure on the hose a sign that the water pump is good. Thermostat opens only when coolant reach normal operating temperature.

My temperature gauge has been fluctuating since summer began

Sounds like your electric fan is not coming on. First check the fan fuse and relay and switch. If all good run a hot jumper wire to fan motor and see if it comes on.if not get a replacement fan motor. If fan is working normally then i would flush the system and replace the thermostat.

2000 malibu runs hot if not warmed up

How do you know it gets hot? Are you going by the temperature gauge on the dash? Or have you checked under the hood and found out the engine really is running hot? ...Reason I ask is, something just doesn't sound right in your description. After just 5 minutes from starting and driving away, the engine would not yet be at normal operating temperature. That would explain the heater not yet warm. But the temp. gauge says hot?
If so, I would replace the temperature sending unit on the engine. the one for the dash gauge, and see if that was the problem-not reading the temp. accurately.
Couple of other things: Are you sure you got all the air out of the coolant system? Start the car with the radiator cap off and let it run until the engine is warmed up fully, then shut it off and install the cap. Does your reservoir tank stay about half full where it should be, between the full-hot and full-cold marks?
If your problem persists. I would have the coolant system pressure tested, and see if you could get a true temperature reading of the coolant when it seems to be running hot.
Good luck.

Heater donot get hot whil running

It could be a plugged heater core or heater control problem. I assume the blower is working, but the air is cold. The first thing to check is the coolant level, make sure there is coolant in the resivoir. Next see if the temerature gauge reaches the normal operating temperature range. If the gauge reads cold most of the time, it would tell you that the thermsotat is faulty and not allowing the engine to reach full operating temperature. If your car doesn't have a temp gauge, the blue cold engine light might stay on for an extended period of time. The thermostat is supposed to not allow coolant flow in the radiator until the engine reaches operating temperature. If you drive the car for a couple of minutes, from cold start, the radiator or upper hose should be cool until the engine reaches operating temp.

Temp gauge is in normal, 200 degree, range when starting. Within a few minutes of driving goes up to 250, right below orange line. No leaks found, coolant level appears fine. Any ideas?

1989 Nissan Maxima Radiator fans and Temp gauge not working.i have a 1989 Nissan Maxima and the radiator fans do not come on. I have replaced the Engine Coolant Temperature Sensor and this did not work....

-The radiator fan will be kick on ONLY when the temperature reach about 190-200. Depend on the sensor that you have now.
You can test it by boil it and hook up a digital multi meter to it.
and make sure use a temperature gage to test with, so you know how hot the water when it kick on.

Good luck

1997 Chevy Malibu cooling fans problem

I don't have the solution but I have the same problem. You are not alone. I have done everything you have done and have run out of options as far as fixing it with OEM parts. I am going to over ride the system with a hot wire and toggle switch and tie into the led wire on the #1 fan so when temp starts to rise past 180 degrees I can turn the fans on. Freeway driving is ok for me, no fan needed, just when I get off the freeway and around town engine gets hot. My toggle switch has a L.E.D. light in it to indicate the switch is on.
