#166 of 209 2001 Lincoln Ls V8 Overheating
May 23, 2012 (3:23 am)
My Lincoln Ls V8 recently started over heating. Mostly on a hot day and on a daily trip to the store about 10 miles away. It will mark at half way temperature on the way there and on the way back it will pass the middle mark. I drove it a bit more and it overheated on me. It leaked antifreeze and I could smell burt coolant. I had my mechanic change the thermostat and it helped a bit but it would still sit in the middle mark. Drove it on a hot day and it over heated on me again. This is driving me crazy. Why does it go to middle temperature so fast? Is the fan not working? Someone please help.

Could be the fan - let it idle and check it in the driveway. Are you sure it's not just low on coolant? Have you replaced the reservoir - it's known to crack and leak. And if they didn't get the air out when they replaced the thermostat you could have an air bubble. You have to bleed out the air using the special bleed valve - it's somewhere near the top of the engine.

Check the Degas bottle for cracks. See my posts on this string. Causes coolant to leak at high RPMs and causes it to suck air into the system as it cools. Thermostat swap probably worked for a while because they bled it, but the problem will recur if the bottle is cracked. It won't leak at idle in your driveway, so it's hard to detect. Pull it out and check the seams. Chronic issue in LSs.
#169 of 209 Lincoln LS V8 (2002) Bad OVERHEATING Issues
Jun 12, 2012 (4:16 pm)
I have a 2002 Lincoln LS V8 with 125k miles.
When I start driving the car, the temperature gauge reaches the mid point pretty quick -- within about 2 minutes -- whether it is a hot day or cool night. It will stay at the mid point anywhere from 15 minutes to 45 minutes, but then the temp. gauge quickly rises and the coolant begins to bubble violently in the tank. If I donít shut the car off immediately and I let it keep overheating, the coolant will leak out of the top of the cap until itís all over the ground. If I shut it off immediately, it takes a while to cool back down. It goes without saying that I often smell burning coolant even when itís not overheating.
Things I HAVE TO DO - (goes maybe 45 minutes without overheating):
-Turn the HEAT on high (no A/C)
-Drive it with the hood popped open.
-Try to drive it at night when itís cooler outside.
Things I CANíT DO - (goes only 15 minutes without overheating):
-Turn on the A/C.
-Sit in stop & go traffic.
-Drive it when itís hot outside... which is hard to do because I live in SOUTH FLORIDA.
Obviously, I pretty much have to keep my travels very close to home.
THINGS IíVE TRIED:
COOLANT TANK has been replaced Ė thereís no leak in the new tank.
THERMOSTAT has just been replaced.
The Ďbleed capí has been removed once to let air out, but didnít seem to make a difference.
Whatís next? :/

***When I try to turn the HEAT on when the car is already overheating, NO HOT AIR comes out.***

That would lead me to think the water pump is bad and it's not circulating coolant through the heater core.

I'm having overheating issues with my 2000 lincoln ls v8. I've replaced the thermostat twice, radiator has been flushed, degas and radiator cap replaced. It doesn't overheat when its cool out but on hot days it will overheat if I drive too far or too much. I've also noticed if I stare the car it wont overheat right away but when I stop, turn it off let it sit for a couple minutes then start it up and drive it will overheat right away. I have no idea what the issue could be. If I need to use an electric fan where would I get one. I would have an mechanic do the work but I would like to give them some idea. I've taking it to several shops and nobody knows what the issue is. Please help

Could be air in the system. Did you bleed it using the special bleed port?
The other possibility is the hydraulic fan.

I don't think it was bled. Nobody could find the bleeder. Well today while I was driving down the road all of a sudden my car dies while I'm driving. It wouldn't start back. The engine would turn over but it wouldn't run. The engine made a loud knocking sound on one side and some smoke came out. I had to get it towed. What does that sound like ?

I hate to say it but it could be a broken timing chain. Hopefully it's something cheaper to fix.
