2000 Linc ls v8 auto question james from ILL.

You must wait for the thermostat to open up, crank your heater on full, you will get only cold air once the thermostat opens it will start to heat up, heather runing wait for thermostat to open youll see your coolant bottle bubble up and go down , then you loosen the bleeding valve if you got one, cooling system service should be done all together , change thermostat,flush the coolant system, replace hoses if needed, if thermostat is shut and wont open up your more likely will blow a hose from the pressure .ty

Is this the jaguar 3.9 engine? If so, you equalize the coolant by adding thru the Degas bottle with the bleeder screw removed.Here's a link:

Hope this helps! don-ohio (:^)

It would indicate a bad hot water valve on the hoses connected to the heater core.

If your talking about the heat inside the car, yes. It is vacuum operated. On the passenger side. The hoses are about 1 inch in diameter. The valve is spliced in one of them. Make sure the vacuum is present before replacing.

No. Not like older cars had. Starting in 2000 it moved to the overflow coolant reservoir. It's a big, black cap with yellow lettering. After adding coolant, make certain you screw on until it clicks. (Its a pressure cap.)

where is the coolant temperature sensor located on a 2000 lincoln ls v8

might have to replace the whole control panel

2000 LS cooling system is a very tough system to diagnosis. Any kind of air in system will totally stop the flow and cause it to heat.That is the reason it has 2 places to bleed the air from the system.The one at the engine where the upper hose connects and one beside the brake booster near the degas bottle(rubber tube with a screw end).
The cooling fan is also hydraulic and has it's own power steering pump.
The good thing about this system is that it uses a cylinder head temp sensor that measures the metal temp and not engine coolant temp. When the PCM sees the CHT reach a certain temp it will start shutting down 4 cylinders at a time and use these cylinders as actual air pumps to help cool the engine down.If this does not work it will then shut the engine down totally until the temps come back down.

The most common problems we see are thermostats,crack degas bottle,or a leak somewhere,and of course air in the system. Have not seen a cracked head yet however did see one that pushed the plug out of the cooling port in the head but this also filled the oil with coolant.
Have also seen cooling fans that would not work until PCM demmanded high speed,caused by a weak power steering pump.

You also could have air in your coolant system. You can't just add coolant on these models after you drain the system or let it run low on coolant. The degas bottles on these models also have a flaw, where they crack along a seam. Sometimes coolant will leak, sometimes not, depending on how high the crack is on the bottle. But what it is guaranteed to do is allow air into your system, which can cause havoc with overheating (air surrounds the thermostat so it doesn't open) and keep coolant from flowing, particularly through the highest point in the system: the heater core. There is a heater core bleeder valve attached to a line near the top of the degas bottle (next to the expension line up top) with a plastic, flathead srewdriver face. Turn the heat on high and run the system at idle for 5 minutes. Then open the valve and keep it open until a steady stream of coolant comes out. (It's like bleeding your brakes.) That will clear any air from the system and at least give you peace of mind that this is not your problem. Then run the motor at 2000 rpms, with the heat still on high, for about 5 minutes or until hot air starts coming out. Release the bleeder valve again until a steady stream comes out. Then let the system cool and check your coolant level and fill as needed. I'd pull the degas bottle and inspect it...should have been a recall.

I just bought a 2000 Lincoln ls V8 3.9L, i've had it for couple of days.I took a drive in it the other day, and noticed the car was overheating. Replaced thermostat, and water pump. Car is still overheating, I need some help?
