If your engine shut itself off when it was overheating then you, have internal damage to your engine. It will have to be taken apart by someone who is knowledgeable about this problem. I would suggest either the dealer or an engine rebuild shop.My suspicions would be warped heads, bad head gaskets, possible seized wrist pins or scoured bearings.You will not be able to repair it by bolting on new parts. You also won't be able to accuratly diagnose the problem without at least partial disassembly.

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.

SOURCE: still running hot after changing therm. 2000 lincoln ls

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.


Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.




You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!


Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost


A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

SOURCE: my lincoln ls v-8,is running hot after i changed

About the only thing left is the radiator. First, and cheapest, is have your radiator cap checked to ensure it is holding to the pressure spec for your car. It may just be cheaper to repalce the cap.

Check the radiator hoses for leaks or kinks.

The core may be plugged and in need of a flush...

Sometimes it's hard to tell if a radiator has enough flow. Here's a couple of quick tests. Although they're not as good as removing the radiator and flow checking it with a machine at the radiator shop, they can be done on the car and are fairly easy.
Feel the radiator fins as the engine warms up. As the thermostat opens, the entire radiator should start to get warm .WATCH OUT FOR THAT FAN!!!!!!!!!!!!!!! If only part of the radiator gets warm, it may be clogged in the cold areas.

Remove the radiator cap with the engine cold. Squeeze the top radiator hose to get a "feel" of how it squeezes under zero pressure. When the thermostat opens and you can see the coolant circulate, replace the cap and IMMEDIATELY rev the engine up (3000 RPM or so) while squeezing the top radiator hose. The hose should remain fairly easy to squeeze. With a clogged radiator, you can actually feel the hose "stiffen up" and get hard to squeeze as the engine speed increases.

The best flushes are two part: a strong acid and a neutralizer. The one part flushes aren't as strong. The strong flushes get rid of more scale and deposits, but you run the risk of 'eating through" the extremely thin and cheap radiators and heater cores they have today.
Prestone and others make a "backflush adapter" which fits in a heater hose and accepts a garden hose.
No matter how you do it, I'd replace both the top and bottom hoses, bypass and heater hoses, and possibly the thermostat.
When you remove the bottom hose almost all the coolant will drain out of the system. You really shouldn't just dump this coolant: be a little "green" and at least pour it down a drain so the wastewater treatment plant can deal with it before it gets in the groundwater!. The best is to go to your regular mechanic and let him put it in his coolant recycling tank. Mechanics are required by law to have one.
Fill the system with water. If you decide to use flush, add it at this time. Start the engine and let it warm up. It might be necessary to hold your hand over the radiator filler while squeezing the top hose: the thermostat will be closed and may keep the water from circulating. If no water touches the thermostat, it WILL NOT OPEN AND OVER HEAT YOUR VEHICLE!!! I always drill an 1/16 inch hole in the flange of a thermostat to keep it from "air locking" like that: the better thermostats already have a bypass hole for this purpose.
Once it is warm, follow the can directions regarding the flush, if you use it. If you aren't using flush, skip these next few steps.
If iut's a 2 part flush, remove the bottom hose or open the radiator drain **** if it has one. (the drain **** will usually be on the opposite side from the bottom hose inlet on the rad. After it drains, replace the bottom hose and refill the system as outlined above. After it has been refilled, remove the top hose. Get a piece of pipe that fits either over or inside the top hose: this will make this step a lot neater.
Put a hose in the radiator filler and turn it on. Run the engine. Fresh water is being added by you via the radiator, the water in the engine is being pumped out of the top hose. Run water through it until the water exiting the top hose runs clear.
Re-attach the top hose and add the neutralizer, if a 2 part flush. Drain and repeat both of the above steps to remove the neutralizer from the system. If a one part flush, as soon as the water runs clear you are ready for coolant. Drain the system as outlined above.
Reattach all hoses, put in the antifreeze first. Complete the fill with water.

My 2000 linclon ls 6 cly cranks but sounds terriable just started doing it

I hope it's not the timing chain tensioner,Chris. I know the 2000 V8 engines had bad tensioners.
Could it be a loose starter or the starter drive is hanging up in the flywheel teeth?
Could it be a really bad DRIVE BELT TENSIONER or the idler pulley gone bad?
It's just difficult to say,but I hope it's not the TIMING CHAIN TENSIONERS. Lot of miles on it? don-ohio (:^)

Honestly, that sounds bad-loud knocking that gets worse, then no start-does it sound normal when it cranks? Does it crank freely? Is your battery in good condition? More information is needed...

2000 jeep grand cherokee has a loud knock in engine. Started out as a ticking sound like a lifter, know it is a loud knock. This is a V-8 Engine

If the noise still sounds like it's on top, I'd remove the valve covers and check the rocker arms to make sure they aren't broken or worn. Also crank the engine over and observe how far each travels. If any are different, a lifter or lifter and cam have gone bad.
If your oil pressure is low or the noise is deep inside the engine, likely you have a crank bearing problem. In most cases it's more economical to get a scrapyard replacement rather than do a rebuild.
Before doing anything like that, have an experienced tech listen to it. Only other thing that can make a noise like that is a broken flywheel. A good tech can tell the difference between noises and give you better advice than I can because he can hear it.

Friend, do a compression check on all cylinders. The one, most likely #3, will show low compression because of a bad valve. This causes the engine to idle rough and once it goes into overdrive the whole vehicle shakes I'm sure. And since you've swapped the injectors around, and it still chows a 303 code, it wasn't #3 injector causing the misfire code. Keep all this in mind friend, this problem is indigenous to all these V6's.

My car has been parked for over a year when i cranked the motor i can hear a knocking noise but only when i press on the gas. there is no noise when the car is running only when i press on the gas.

I am sure you have checked the oil. I would change the oil to start with. This sounds like a main bearing problem but if it did not knock when you parked it then I would change oil and if the knock persists have your oil pressure checked that will also give a clue to a main bearing problem.

Oil in 2000 lincoln ls is 4 quarts low after only 3 months, now there is knocking in engine.


This noise can mean bad news, but, let's not panic and try something.

Some times when oil level gets too low, the lifters discharge and valves start making a quick knocking noise that doesn't quit even if the oil level is normal.
and increases when you step on the gas.

This happened to my friend's car and fix the problem adding a Valve Quiet oil additive, in a couple of minutes the noise was gone.

If this is not the noise you are hearing, take it to a mechanic shop for repair, preferably on a Tow Truck, because the more you run the engine, the more damage you can cause to it.

Good Luck
