For everyone that is having overheating problems here it is: first what you need to do is when it is overheating pull over(don't shut-off engine) and check if the fan is blowing air not just a little but a lot. If you don't feel air blowing the fan is not engaging on high. There is an actuator on these hydraulic cooling fan systems. The acuator is on the back of the pump on the passenger side. The acuator will tell the pump how much fluid to let go and make the fan spin at low, mid, or high. Now if the fan is blowing then you have air in the cooling system. If there is air in the cooling system the coolant in the degas bottle will act like it is boiling. You have to follow the procedure to bleed the air out but if the degas bottle is cracked, the cap is no good or if any hose are leaking or the plastic T on the upper hose is cracked it will keep getting air back in. Ok, now with the engine off try to spin the fan by hand. If it does the fan motor should be working. Also, if the hydraulic hose from the fan motor was removed to take the water pump off you may have got air in the hydraulic fan system causing the fan to not spin properly. Now you have to get the air out of the hydraulic system. So, if you have changed water pumps, thermostats, degas bottles and no luck you have air in the system(both) and if the fan is not working more likely it is the acuator. It may be the hydraulic pump or fan motor. I'm not a certified mechanic but I've been working on cars since I was 16 about half my life now and I also have 2001 Lincoln Ls. Let me know if what I said helped or you need me to explain further on one of the subjects more.

christina, i'm currently having that issue right now. I called the dealership and they can take it out for like 90 bucks. I also spoke to a mechanic and he said people have got another cap drilled a hole on top tapped it and put some kind of valve you can open after the car runs for a few minutes. This suppose to let the air out. I asked him how to they do it and he didn't want to tell me. They probably have a machine or something. I have tried a few other things that made it work but it stopped working again. I disconnected the return, plugged the nipple to the bottom of the reservoir and put the hose in a empty trans. fluid bottle. I then asked someone to turn the car on and watch the fluid go down in the reservoir(not too low and only a few sec.) then turn the car off and refilled the reservoir.Repeated about 5-6 times. This helped but just for a little while. Its probably is something else. Going to take the acuator off and test the resistance to see if it is working like it should before i buy one. If I can't get it working again, I'm just converting it to electric. Wanted to keep it the way it was.

The only time it should get hot is idling or stopped. When you are moving at high speed on the highway the airflow through the radiator is enough to cool the engine. The electric fan will only kick in at low speeds or stopped for any lenght of time.
My problem is the LS V8 I have is overheating all the time. Although the engine is getting hot, the hoses are not getting hot. This makes me believe its either the thermostat or water pump. The fan seems to be working really fast with lots of airflow, but the engine is still overheating
It was fine untill yesterday afternoon, and now it overheats whenever I start it.
Any suggestions gladly accepted

Hi read your post on the actuator is there a way to test this? And is this what the part is referred to at the store or is there a part #? My fan is not increasing speed as it heats up hoping it's this. Thanks so much for your directions.

Jiminy2, don't know how many ohms it should put out with a meter but if you find out let me know. The part # XW4Z3783CA. Easy to replace. Drain fluid from reservoir or suction out. Remove reservoir and hoses out of the way. Then you see wiring coming from back of pump that is the actuator. Use a torque think a T-40 to remove actuator. Fluid will come out. Replace put back together.

Pretty sure you just move the steering wheel back and forth.
#103 of 195 02 Lincoln LS overheating
Aug 23, 2011 (11:56 am)
I have an 02 Lincoln is and its overheating when i turn the ac on. I've seen a lot of people have had this issue b4. I took it to my mechanic and changed a pipe that was cracked and have the the system bleed of air . However, the car still overheats even though the AC is off. I have noticed usually, when I am on my third trip while doing errands the tempature gauge indicated that it is overheating. I turn the car off and restart so that the temp gauge falls back down. has anyone ever gotten this prob fixed. if so pls let me know cause its frustrating to me. my mechanic doesnt know why it still heats up. He states that pressure is checked and there is no air in the system. The radiator is fine no problems with coolant or leaks. The check engine light engaged once before it was serviced. Car continues to overheat without check engine light. He did mention that the Hydraulic fan code came up on the diagnostic but does not know the specifics and instructed me to visit a Lincoln dealership to verify the problem. At this point I am wondering if anyone can let me know if they had this problem and if so what was the problem and what was the remedy. I wonder if anyone has successfully completed this issue. Thanks ahead of time.
