My 2000 Lincoln LS is leaking hydraulic fluid. I have been told that it is leaking from the rear seal on the cooling fan pump. Where would I go to get this pump. In other words, would it be available on the secondary market or would I have to get it from a dealership?

Hi JOHN,HERE'S A LINK ON HOW TO FIX YOUR PROBLEM,I HAVE A 2004 LINCOLN LS 3.0.I HAVEN'T HAD THIS PROBLEM,MY VALVE COVERS LEAK AND MY TRANSMISSION JERKS AT LOW SPEED. How To Repair Hydraulic Fan Pump Actuator Solenoid
There is no relay on the cooling fan circuit.
If the cooling fan is not operating, check fuse #105 (20 AMP), in the underhood junction box, right front of engine compartment.
If fuse is good then test to make sure fan is getting power.
If no power then could be bad cylinder head temperature sensor, hydraulic fan solenoid, a/c cycle switch or the PCM.
If it has power but doesn't come on then fan motor is bad.
dont know but 1 thing for sure i was told to replace the fan , so i had it replaced, turns out now the problem may be the power steering pump , ur fan isnt electrical it is a hydraulic ran fan, and is fead with power steering fluid and runs when power steering pump pumps fluid thru, or as simple as a heat sensor which im gonna replace both
Radiator cooling fan is not electric, it is driven by a silly hydraulic pump which is located low on the passenger side of the engine above the alternator. All 2000-2002 LS's have this system. Most likely either the motor or pump has failed.
the fan speed could be one problem...the other problem could be wth the radiatr cores being blocked..check whether the heat on your radiator is even front top to bottom and on all sides...if it is not, clean the radiator and check for the problem
Sometimes a vacuum leak can cause the engine to run lean and hot, Have Auto Zone run a free code check on the car to search for a stored trouble codes this may help.
The cooling fan on the LS-V8 is hydraulic yes. But it also has a pressure switch on the pump that drives the fan. It is controlled by the temperature sensor. All these things must be taken into account. But the whining sound my lead me to believe that the pump is either low on fluid or is wearing out. The fluid the fan pump uses is the same as the power steering pump container so check it first. The same thing happened to my wife's Lincoln. I replaced the fan as well because everybody told me to do that but it didn't work. I found out that the fan is just a hydraulic motor in reverse it only spins as fast as the pump makes it spin and that is controlled by the temp. sensors. When the engine get's hotter the pressure goes up and the fan spins faster. This adds more power to the engine when it's running cooler because the fan doesn't have to spin at max speed. So good luck. I hope this has solved your problem.
