Question about 2002 Lincoln LS

2002 Lincoln LS, V6 overheats

I have been having issues with my 2002 Lincoln LS overheating. I have replaced the Cooling Fan, the Thermostat, and the Upper Radiator Hose assembly in behind all of this. Antifreeze got all over the place, so I have replaced the Ignition Coils and Spark Plugs for 4, 5, and 6. I run the A/C for a while, and it overheats. I turn on the heat, and the Temp goes back down (the gauge). I've also noticed something strange...sometimes, I'll give the car a little gas, and it stutters...the RPM's don't go up at all..this causes the car to overheat as well...again, I turn the heat on for a minute, gauge goes down. What could cause this? What can I do?

    I'm not sure if the air was purged out of the system..how would I go about doing that? I turn the car on and the fan comes on, but I was told that it should pick up speed at some point...my fan stays the same speed. I have checked the fuses and relays, and they are all ok...the computer, I'm not sure about that one...

I've replaced the water pump,thermostat, and hydraulic fan that was barely moving on Lincoln ls 3.0 v6 but still continues to overheat.Removed tstat just to get home.Why would it still be overheating?


There are usually only three major reasons why cars overheat. The first is a water flow issue. You have make attempts in that area with the water pump and the thermostat. The second is an air flow issue. You addressed that with the fan. The third is an engine malfunction issue, such as a blown head gasket or worse.

There are still a few things you can check..first, the radiator itself could be clogged up, restricting water flow. Second, verify that there is nothing restricting airflow through the radiator such as dirt, bugs, debris, etc. Also, ensure that any fan shroud that should be in place is there and properly installed. These can cause lack of air flow through the radiator. Last, have the engine checked for a blown head gasket.

I have a 2002 lincoln ls it was running hot I needed a hydraulic cooling pump a thermostat and water pump replaced all of them and still running hot


Overheating on an older vehicle, especially one with high mileage, is not uncommon. Aside from the parts you mention, such things as fan clutch failure (or, alternatively, electric fan failure) can cause a car to overheat quickly at idle. If the car was poorly maintained, not enough antifreeze over a course of years may cause coolant channels in the engine block to rust shut, rendering the cooling system ineffective. Something as simple as obstructions to the front grille or rust clogging veins of the radiator can also reduce cooling capacity. A worn engine will also heat up very quickly under load.
You will need to observe when your vehicle tends to overheat (at idle? when driving? when climbing hills?), and use that as a point from which you may start diagnosis. Some things to check immediately are:
  1. Remove any physical obstructions to air flow from the front grille;
  2. Check the operation of the fan clutch or, if your Lincoln is so equipped, of the electric fans (especially if the vehicle is overheating at idle or in traffic;
  3. Is the vehicle burning oil? Have the engine overhauled;
  4. Check for signs of rust buildup in the cooling system. Has the proper 50/50 ratio of ethylene-glycol coolant to clean water always been maintained? If not, suspect damage to the engine's cooling channels from corrosion or mineral buildup.

Radiator Fan always Running


Temperature sensors trigger cooling fan. But can be a stuck cooling fan relay that refuses to disengage.

This fan will strain charging system and may cause engine to run too cool at times.

Put a new hydrylic fan on 2001 Lincoln Ls now it still runs hot, fan isnt kicking on what could be the problem?


Yes we had a Saturn which we thought was running hot and the gauge was always in the centre or over but we had the fan checked and it was working. Our thermostat might of been faulty but we never had a overheating issue..My Mechanic said that we should get a coolant flush that might help.

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...


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.
