It depends on how hot it got. You need to get an accomplished mechanic to checkit out.

or

You can check for compresson by removing your plugs one at at time checking for compresson by letting someone turn the key while you check for compresson, if your compression are weak you might need to remove everything from the top, from intake manifolds, to head gaskets, then from the bottom you need to remove the oil pan and the muffler assembly, once the top and bottom are removed you can remove your pistons from under by pushing it upward, you will have to unbolt some nuts from the connecting rods to push out the pistons, once pistons are out check for wear and scratches on the pistons and cylinders, replace piston rings and reassemble back to how it was removed.

because it's been overheated and damaged.

You run the engine till warm then look underneath and see if the pump is leaking. A faulty pump leak is very visible in Taurus/Sable.

i have found that with my 97 sable the low coolant light comes on when my oil is low. same as your car can run hot when your extremely low or out of oil

The oil pump inside the engine is probably busted. If you start and run it you will probably ruin the engine. Probably $100 to fix now or $7000 to fix if you ruin the engine. Don't drive it or run it any more.

Get a Haynes Manual, A Chilton Manual. You can get them at Autozone, Advance Auto, or Napa. They Run under $20. And they are very helpful.

Run a compression test. If compression is down in several cylinders you've probably warped a head. That's a common problem after an engine has overheated, that's why it's so essential that you NEVER allow an engine to run out of coolant, and you should watch the temperature indicator. If an engine dies from being overheated you've probably blown a head gasket.

Make sure the switch is plugged up correctly, and not up or down just A little,,,,,,,,,,,,,,, If correct, you got the wrong switch.

The computer is protecting the engine by not allowing it to start or run while in an overheated condition. Once the engine cools down to a safe operating temperature the computer will allow it to be re-started.

That engine uses a timing chain. Chances are very slim that the chain jumped time. However if it did jump time the engine would not run and the engine would have no compression. Tell us what the symptoms are.

if there is no cable and your book says there is or someone at mercury says there is don't believe it... run one yourself and if you can't have someone at a stereo place do it.

Oil yes. Sludge from overheating maybe not. Might be able to run some engine oil flush through the oil system and see if it cleans it out. Don't drive the car with it in the engine and change the oil twice after you drain it all out to be sure you get all of the kerosene out. Otherwise, you will end up with a locked up, overheated engine.

If the pump is working properly it is very hard to hear it run. You can however hear it if you remove the gas cap and listen at the fuel filler while someone else turns on the ignition without starting the engine. It will run for a few seconds and then shut down which is normal. It will only continue to run when the engine is started.

DEPENDS ON THE SIZE OF THE MOTOR, MINE IS A 3.8 IT USED TO GET 18-22 BEFORE THE OXYGEN SENSORS WENT BAD. 3.8 HAS TWO OXYGEN SENSORS, (LEFT AND RIGHT SIDE), THEY RUN ABOUT $60.00 FOR ONE, NOT INCLUDING LABOR.

that is just the way it is ,it's a clutch fan and it will stay turning until the fan stops. It is not a clutch fan it has two fans and they are electric, but i have the same problem they run and dont turn off utill the battery dies.

Run a compression test. When engines overheat the head(s) often warp causing the head gasket to blow. If you find low compression between any two cylinders OR if any of the sparkplugs are wet with water or coolant as you do the compression test, it's the head gasket and warped head. BTW, that's one of the most common problems that shows up after an engine has overheated.

possibly clogged heater core, remove heater core hoses and flush with a hose until clean. reinstall hoses fill with coolant and let it run. if heater core is too plugged up you will have to replace it.
