You should always start by changing the thermostat. It's only like 17 dollars from Ford. Also highly recommend Ford only on this part.
Then you need to properly "BLEED" or burp the coolant system on LS's. They have 2 special bleeders on these cars that need to be used correctly.
Also, are you aware your car has a hydro cooling fan that runs off an engine pump? It is almost same setup as your power steering system. There can be a problem with the pump not pumping right or the hydro fan motor not spinning right. When you over heat, pull over, pop the hood and see if cooling fan is spinning, then turn on the AC; the fan should kick on to HIGH speed, watch for that. If those are not happening, have Ford look into it.
I have a 2002 Lincoln LS. Most of the problems everyone is having I had from coil packs to overheating.
The overheating is caused by air in the system. What happens is when the air bubbles pop, it sends the temp up and reduces the power down, and you have to shut the car off for around 10 minutes. What you have to do is open the coolant cover, and let the car heat until all the bubbles come to the top. It takes me around 45 minutes, but no more overheating.
I have a 2001 Lincoln LS V6 with 19,000 miles on it. The car has been in the family since it was purchased in Tucson, AZ. Excellent dealer and excellent service.
However, the car's fuel pump catastrophically failed at our home in CA when we reached 19,000 miles. The local dealer has now had it for 9 weeks waiting for a replacement fuel pump to repair it. Ford has been urged to provide a replacement fuel pump. They have indicated several weeks ago that the part would ship within 24hrs. Three weeks later - still no fuel pump. Ford now says that they cannot provide an expected time of arrival for the fuel pump. I think they want to detach themselves from any responsibility to provide spare parts on older cars and any liability for any accidents that may arise when the replaced fuel pump, if I can get one, fails in traffic.
This car is essentially brand new, 19000 miles. Held in storage for several years. Ford has the part recorded in their records as having "Commercial and Design" issues. Ford is forcing me to try to locate an after market replacement part because the fuel pump has "commercial and design issues". If the pump has design issues, I suspect that any after market supplier is going to inherit those design issues and ultimately provide me with an unreliable replacement. After nine weeks, still waiting for a fuel pump and worrying if I can ever safely drive the car even if I locate a suitable fuel pump. Advisors & Lawyers contact me at email@example.com
After reading all of the above comments I don't feel alone anymore. My LS engine just died 5 days ago. I have had all of the above problems and would be interested in a class law suit.
PLEASE people STOP with this class action lawsuit silliness. You all have 9 year and down old cars. Your warranties expired like 5 years ago. Things break all the time. If you don't think motors, trans and other things don't fail on other brand cars, you're mistaken.
Also the person with the 19K 2001, just go on Ebay and find pump in 2 seconds. Why all the complaining over a simple fuel pump that pops right out of the car from under the back seat in minutes.
Also I like how dramatic you get over a basic fuel pump failure "catastrophic failure", what was catastrophic about it? It stopped working?
I agree with the above commenter. I mean we all agree that Lincoln's LS is junk, but there is little you can do about it. Even if you HAD a case against Ford, do any of you actually think that you could get better lawyers than a multi-billion dollar a year company like Ford? I know they aren't doing too hot economically right now, but I mean really, they'd eat all of you alive and all you'd get is lawyer fees and court costs for your trouble.
Like I said in an earlier comment, if you could afford better lawyers than Ford, then you wouldn't be driving an old busted LS!!! So either fix your car or sell it. That's your options, that's life. If you want a real Lincoln, buy a 1971 Mark III or a 1962 Continental suicide door car. Or just settle with the crap your driving.
I have a 2004 Linc LS and I'm having misfire problems. I replaced four of the six coils and still I have the problem. At times I smell burning water I think the head gasket is leaking. I took the car to a mechanic to check it out. I love the car, the way it looks and drives when its running well.
I have a 2000 Lincoln LS V8. I absolutely love that car, but sometimes I don't feel like I'm getting that love in return. I haven't had many major problems from it, but windows, the cooling system and suspensions all sounds familiar. I've had to replace the alternator twice. $450 a whop! Fortunately I had a warranty. It just seems when something gets fixed something else breaks.
I also own a 2001 LS V8 with 110,000 miles and have owned it since 69,000. The car has been an awesome car, and even survived a cross country trip from Seattle to Mississippi, and back to Seattle all while towing a uhaul trailer with all our belongings.
HOWEVER, it seems I am starting to have a misfire under load at about 4000 rpms. If I don't get on it, it drives fine around town.
Also is starting to sputter when in 5th gear at 1500-1800 rpms around 45- 50 mph. When it does this, it does not trip the misfire or any code from the check engine, it just starts to jerk like it is losing power. Anybody have any ideas about this sputtering and jerking??
I understand from the previous posts that I may have some failing valve gaskets and coil packs, or a failing jet pump for the misfire, but what about the jerking?
This sucks because I don't have the money to fix this car right now, and it seems like expensive repairs. Any advice would be great.
The only other problem I've had with this car was the power steering pump gave out, and that was 400.00 with labor and everything from Goodyear.
I also liked the Lincoln LS, I bought a 2000 3.9, Currently I have been having overheating problems with it and found that the fan is operated by the power steering pump. with a leaking pump low fluid will cause your coolant fan to operate correctly in stop and go traffic. so check to make sure your fan is running correctly and then go from there. Good luck LS owners.
