Question about 2002 Lincoln LS

1 Answer

My 2001 lincoln ls v6 and my cooling system isn't working right. It overheats and the guage is spuratic. It starts to cool down and in a split second it is over heating the guage is tacked and the alarm beeps 4 or 5 times and then it goes into the mode where some cylinders shut down. Why is this happening and how can it be fixed?

The most common thing if there is no visible leak would be #1-thermostat has gone bad #2-fan clutch or electric fan not working. Good Luck.

Heater on my 2001 Lincoln LS blowing cool air. Engine fan keeps coming on. Temp gauge goes up to highest level, then returns to midpoint. Does not overheat. Are all of these things tied together and how...


Yes more then likely it's all tied together... Check the coolant level it's probably low or you need to bleed the air out of the cooling system...

My 2001 lincoln ls v6, the heater works fine except it doesnt blow out hot air. only cold, the car temp gauge is working normal too


It's possible the cooling system is just a little low on coolant. There could also be a valve in the heater hose that is failing to open and let the coolant flow through the heater core. It could also be the heater core itself. Did it start doing this gradually or did start all at once? If it came on gradually it most likely the heater core or low coolant, if it happened suddenly it's a valving or heater control problem. Good Luck.

I NEED A DIAGRAM OF THE HEATING AND COOLING SYSTEM FOR 2001 LINCOLN LS V6. THE HEAT IS NOT WORKING


Your best bet is to get a Haynes Manual from an auto parts store. It will give you the full schematics of all the electronics in the car. You probably won't find the Manual on the shelf with the rest of them, but they can order it and it normally takes 2 days max. for them to get it.

Have you checked the relays and fuses?

2002 Lincoln LS V6. AC blowing hot air but sometimes it works fine and blows cool. Is it a sensor problem?


its probably the compressor cutoff switch cutting your compressor off at the wrong time and causing your ac to blow hot. that switch is under your hood right on top of the engine easy to get to. I hope that helps you out!

My 2001 Lincoln LS keeps overheating


No your right change the thermostat and antifreeze and that should fix the problem about $30.00 do not drive till you do the work or you will damage the engine. also make sure the cooling fan is turning when it gets hot but only for a few seconds.

My 2001 lincoin ls gauge goes up to the h and then come back down


you probably have air trapped in the system. Have dealer or radiator shop bleed system.

I assume your cooling fan is working.

what engine v6 or v8?

SECTION 303-03: Engine Cooling 2001 Lincoln LS Workshop Manual
DESCRIPTION AND OPERATION Engine Cooling The cooling system components include the:
  • block heater (optional)
  • cylinder head temperature sensor
  • fan blade, fan motor and fan shroud assembly
  • radiator
  • pressure relief cap
  • degas bottle
  • radiator draincock
  • water pump
  • oil cooler (optional)
  • water thermostat
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for system fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan blade draws air through the radiator to help cool the engine coolant.
The fan motor:
  • operates only when the engine is running.
  • will not operate when the engine is off.
The engine coolant flows:
  • from the lower radiator hose to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump. An open water thermostat allows the engine coolant to flow to the radiator.
Unsatisfactory coolant materials:
  • Alcohol-type antifreeze does not provide adequate water pump lubrication.
    • has lower boiling point
    • reduced antifreeze protection
  • Alkaline brine solutions will cause serious engine cooling system damage.
The cylinder head temperature sensor provides a signal to the temperature gauge.
  • will invoke failsafe cooling.
The optional block heater:
  • electrical heating element is installed in the block cooling jacket.
    • uses a standard 110V (220V in Europe) electrical supply
  • keeps the engine coolant warm during cold weather.
The auxiliary water pump (3.9L only):
  • provides heater coolant flow boost.
  • has a secondary function of providing engine-off cooling.
