Engine fans not working overheating


Turn the ac on the fans should always come on. if not look in the fuse box for a bad fuse and or a fan relay. then look around the fan area for a finned module this is an electronic fan relay. i think this controls the fan speeds.

2006 Hyundai Tiburon Overheating...solutions?


If it starts getting overheated right after being started cold and it's full of coolant the therostate may be stuck shut. If it has to run awhile and be under load the radfitor may be dirty or the coolant dirty or badly mixed. the raditor where the air goes thought it may need to be cleaned. If you have to sit still but if you k moving it's Okay then the fan ( It's electric) may not be coming on. You can turn the fan with your hand isee that it will turn ( they lock up) or you may have seen it running and know that this is'nt it. Itb shoud blow hard though and if it does'nt the high speed fan relay might be bad or the main fan fuse blown. If the fuse is blown the fan motor is likly to be bad evcen if it runs with a new fuse as the fuse blows as the motor heats up and draws more power.

What would be the most common problem besides the fuse, that my fans are not working and thus may be the reason my car is overheating and the solution to it. I have a 1986 Cadillac De Ville 4 Door V 8. I...


It could be several things.
1. Fan relay, as this controls power to the fan.
2.Blown fuse or tripped circuit breaker, usually both located in the fuse panel
3. Thermostat that tells the fan relay to start based on heat at the radiator.

Each of these need to be verified as working properly prior to any additional troubleshooting.

Overheating


IT COULD BE THE FAN FUSE OR FAN RELAY, IF THE FAN IS DRIVEN BY THE ENGINE TRY CHECKING THE FAN CLUTCH. IF THE FAN SPINS FREELY WHILE IT IS COOL, THEN WAIT FOR THE ENGINE TO HEAT UP AND SHUT THE ENGINE OFF AND TRY TURNING THE FAN BY HAND. IF THERE IS LITTLE OR NO RESISTANCE THEN REPLACE THE FAN CLUTCH. IF THE FAN IS ELECTRIC THEN REPLACE THE FUSE AND RELAY LOCATED UNDER THE HOOD IN THE FUSE PANEL. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. BEST OF LUCK.

Temperature sensor problem?


There are 2 different circuit that control the cooling fans.
The engine controller turns the low speed fan circuit on to control temperature and turns on the high speed fan circuit if the engine and A/C is running.
It sounds like your low speed fan function is not working.
Find your fan 1 fuse located in the under hood fuse panel and make sure it is not blown. If OK go to next step.
Find your fan 1 relay located in the under hood fuse panel. Find another relay in the fuse panel that matches and swap the two. If the fan then works you know you have a bad relay.
If both are check good, let me know and we will go from there.
Below, I have attached the wiring diagram for your cooling system, hope it helps.

Overheating


Hi,

Most normal causes for overheating would be:
  • clogged radiator,
  • insufficient coolant level (radiator and reservoir);
  • too soft radiator hoses;
  • defective/leaky water pump (impeller);
  • water pump belt/tensioner;
  • thermostat (mechanical);
  • thermal switch;
  • radiator fan, fan clutch;
  • fan relay;
  • fan fuse.
In some instances, the fan only works in conjunction with the A/C and/or heater and therefore would only work if either of those two are enabled.

Should your particular vehicle be using a radiator fan with clutch, that could also cause the fan blades not to spin even if the fan motor is turning.

Pls check the above mentioned components.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
