SOURCE: Are both radiator fans suppose to come on together?

I found this forum site and from what I can discern, both fans should be running once engine temperature sensor turns them on. Can you switch wiring from 1 fan to the other? This would let you know whether you have a faulty motor or relay. Maybe you can pick up some tips too.

Check the lower radiator hose to see if it has gone "soft" Check when the engine is cool and stopped, grasping the hose and giving it a squeeze, you should feel the presence of a "spring" in the hose. That should be there to prevent the hose from collapsing as the water pump draws coolant through it. Without the spring, the draw created by the pump intake, and the resulting venturi effect will collapse the hose, cutting off the flow.


If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

I have a 2001 mercury grand marquis ls. it overheats when im driving it but don't shows it on the temperature hand ..what is the problem ??


The temperature switch on the side of the upper radiator hose is not working. That is, if the engine is hot. Boiling over - need to check thermostat. Grab on to upper hose (should be hot) than with engine off, grab bottom radiator hose. It also should be same temperature as top. If so, thermostat ok. Electric radiator fan - turn Ac on. Fans should run. No, check fuses & relay. Mechanical fan - with engine off, the blade should be stiff to turn. Easy, replace fan clutch. Usually, low level of water is most common. Wish you well.

What should i get replaced on a 2000 marquis with 122,357 miles


Check spark plugs and wiring,very easy to replace,just tape your sparl plug socket to the extension so socket can withdraw and plug usually comes with it.
Change out the rear end grease and you add anti-slip additive in proper proportion.Check drive belt,fan clutch and water pump for play,flush radiator and heater out.
Change out ****** fluid, and I will tell you a great secret......................Look on the bottom of bell housing and you'll see a plastic plug.GUESS WHAT!? By bumping the engine around or turning the crank slowly,you will see a ****** DRAIN-PLUG appear.....yes! You can drain ALL the fluid and replace it properly.
Of course you need to look under the car and check the brake lines for bad corrosion,just like on any other car.It doesn't hurt to have someone flush new brake fluid thru the calipers at that age,either.don-ohio

I have a 1999 Grand Prix. It has a new water pump, new thermostat, new radiator cap, new hoses top and bottom off the radiator. Car is still running hot after a few moments. I don't hear no boiling...


Check to see if your electric fans turn on. Your fans are there to help cool the engine as well. Depending the setup will depend when they come on. Usually they are set turn on when your engine reaches a certain temperature to assist cooling the engine.

Car runs well but after driving it awhile the fan does not come on. the temp gauge in the dash does not go up past halfway but steam comes from under the hood.the fan works and i replaced the temp sencer...


Typically when there is steam coming from the hood there is a pin hole in the radiator or hose. Most of the time when I see this problem there was a small chip in the radiator from a stone. It would allow steam to push out of the radiator but it was small enough to not allow any fluid to drip out. Hope this helps!

02 jeep grand cherokee not running when temp gets high. replaced radiator fan relay


If it's still getting too hot (above 210F) check the radiator for internal plugging and externally for obstructions (leaves etc between radiator and A/C condenser, condenser plugged with bugs etc) If radiator takes a long time to fill generally it is internally obstructed. You replaced the relay...is electric fan coming on now? is clutch fan working? Is aux fan working with A/C? Any external leaks? any steam from tailpipe? You have a bunch more to look at!!!
Good luck
Problem with anything while testing, just ask!!
