Please run down these guides and report back. Cheers,

I found the head gasket was blown I had to pay $1500.00 to have it fixed. Great site though :)

Hello i have a Lincoln Continental 1998, it has somewhere around 130,000 miles on it and the engine is 8 cylinder 4.6 281c, it started to overheat a little while ago so i changed the temperature sensor and the thermostat and it's still overheating. I thought that it might be a blown gasket but there are no bubbles in the cooling system, so i started looking what else could be the problem. I found out about the Valuable Relay Control Module, the one that is located on the top of the cooling fans. And it also said that this module is responsible for turning the A/C clutch off, and right before the car started overheating, sometimes the air conditioner would just turn off and then come back on. So i focused on this module. Can you please tell me if you think that this is the problem. Maybe you can tell me if there is a way to check this module. I searched everywhere for it but i can't find it. No matter where i look for it, i type VCRM and i they can't find it, even in the FORD website by part number. Maybe you can tell me where i can get one as well. Thank you very much.

RusMishania, do you ever hear the cooling fans running? Turn on the a/c and see if the fans come on.If not , my software shows your car doesnt have the Constant Control Relay Module, it has low and hi speed fan relays. If no fan, use a test light and check for power and ground at the fan, get back with results

I just put the Module and the two relays that come with the module on the same plastic bracket back in. I started the car and the fans weren't working. As soon as I turned on the A/C both of the fans came on and i think i heard the compressor come on.

By the way can you tell me for sure if this is the module that we are talking about? In the repair manual they call it VCRM Variable Control Relay Module, you called it Constant Control Relay Module, is it the same thing we are talking about? Here are few pictures of it.

What is the exact production date of your car? (sticker on inner d/s door sill). Does it still overheat? If it does, have it chemical tested for a blown head gasket just to be sure we arent chasing our tails

The exact date on the door is 09/97. And to tell you the truth i don't think that there is a need to check for a blown gasket since i started the car yesterday and the fans weren't working but when i turned the A/C on both of the fans came on. Then the car got to normal temperature, stayed there for a little while and started to overheat. I checked the fans and they weren't working with or without the A/C. Somebody told me that it might be a problem with the PCM since the PCM monitors the temperature of the coolant and monitors the air and then sends the signal to the Relay's, one of them is for high speed and the other is for low speed ( the way i understand it), so it has to be something eclectic that commands the fans to come on. And i have no idea how to check the PCM or where to buy a new one. I heard something about reprogramming it, but i have no idea how to do that as well. I wait for your answer, please help.

Low speed relay- Check for power at #30 and 86 with car running,85 should be the ground signal from PCM to turn on fan when it gets hot
High speed-Power at #1 and 3 running, ground at #2 when the PCM wants it to turn on. Check these things, if no signal from PCM when hot, might be time for a new one, or have the it reprogrammed at a shop with the proper equipment or more likely the dealer

Hello, i wired the fans on the high speed straight to the battery and took a ride. At first the temperature stayed normal, so i gas it up a couple of times pretty good just to check if it's still going to stay normal and then it started to go up again but not as fast as it did before. And the temperature never quite made it to the red but it did go as high on normal as it could. So looks like there is a mechanical problem, do you think it might be a gasket seal? And what else do you think it could be? Thank you for your help, i will wait for your answer.

If you have replaced all you say, I would have it chemical tested for head gasket

I bought my car and on the way home it got hot I killed it and parked for a few months I thought it blew a hose or head gasket wasnt sure Well I decided toadd water change fuel filter, rotor bug and distributer cap and fire it up after a long try it finallly started and it was missing like crazy but the water was coming out the tail pipes and missing like crazy I could barely keep it ideling enough to move it but I have never seen a car shoot water from radiater to right out tail pipe, What is causing all this.
It is a sweet car and very nice i hope this dont become a expenseive ordeal.

If the water coming from the tail pipe is from the cooling system, I suspect you may have a blown gasket at best, perhaps a result of the over heating.
This is a costly repair. Unless you can confirm this yourself, taking it in for a estmate is in your future.

My 97 Lincoln has been serviced by Lincoln for its first 125000 miles I have all the books and records. With that being said. My problem started about a year ago, with it overheating if I drove it more than 50 miles. Now it overheats 6 to 8 miles. Four different shops have tried to fix it. Parts replaced, Water pump, Radiator, Cap, Hoses, Thermostat, both fans, Trans axle flush plus 4 mechanics. Any .i.suggestions?.......

other than the gauge reading, have there been signs of overheating i.e. coolant steaming out..

Keeps overheating . 11/28- replaced upper and lower radiator hoses, water pump, thermostat and thermostat gasket.

12/3 - overheated again. said thermostat was defective and replaced, again, hoses, and thermostat, thermostat gasket, and radiator reservoir cap. Additionally replaced the serpentine drive belt, drive belt idler pulley and puller tensioneer.

12/7 trip - with similar symptoms (overheating and loosing coolant). Tightened something.

12/15 - similar symptons; said they could not find any problem, although they witnessed the coolant loss. Suggested the fan relay system and suggested we try a dealer mechanic.

12/17 - Ford dealer replaced radiator, hoses, PCV valve assembly

1/27 - Running rough, replaced coil asy, gaskets, spark plugs, degas cap. Picked up the car - went 5 miles and it overheated. Said they are not finding the problem - there is none of the gasses that we would be expected if it was the head gasket.

Thoughts?

Head gaskets can cause many different symptoms.Dos it still leak externally? If so the cooling system cant work properly, it needs pressure to keep the water from boiling.If no external leaks but it is losing coolant a head gasket may be the problem. You can have a chemical test done on the cooling system to detect the prescence of exhaust gasses. NOTE: sometimes head gasket leaks cannot be detected through chemical testing. Disassembly is the only way to check it.

first the electric cooling fan locked up an started smoking almost catchin fire so i foun them an changed them out the car would run fine for a while till the thermostat will open then straight to overheating i changed the themostat twice an had the water pump changed i cant figure out what is causing it to run hot it wasnt doing none of this before the fan locked up an almost caught fire thanx Please Help an the fans are working like they are supposed to itll run at normal till the thermostat opens then straight to hot sometimes taking up to 30 minutes i dont know please help

There may be a restriction in the system or damage done when the overheating occured such as a head gasket. Be sure all of the air was bled out of the system.

Steering problem
1991 Lincoln Continental 6 cyl Front Wheel Drive Automatic

changed the powersteering pump changed the rack and pinon car is still hard to steer and pump is overheating fluid is boiling what could the problem be ?

You did use power steering fluid? This is an oil, it does not boil, it airates(bubles) When all these parts are changed getting all air out of the system can be tough, a vacuum pump method is prefered, but you might be able to do it by turning the wheel full from stop to stop for at least 5 minutes, do not hold wheel against the stops, as this can destroy the pump seals. Bulletin No.: 93-26-5 Date: December 22, 1993 This bulletin supersedes the following Technical Service Bulletins: 93-7-3 dated March 31, 1993 93-3-4 dated February 3, 1993 92-21-2 dated October 7, 1992. SERVICE INFORMATION ISSUE Noise heard from the Power Steering Pump may be caused by air in the system. ACTION Purge all air from the system to eliminate any noise caused by air. Perform the following "Purge Air From Power Steering System" service procedure for either of the following conditions:  For all power steering noise complaints and evidence of aerated fluid. If noise persists, proceed with service diagnostics and repair procedures.  For all vehicles following the disconnecting/decoupling of any power steering hydraulic connections/couplings. This does not include fluid top off procedures. FLUID LEVEL TOP OFF - PROCEDURE 1. Check and fill pump reservoir to dipstick FULL COLD or remote reservoir center mark. 2. Disable ignition by disconnecting the EDIS/DIS/TFI module or, for remote TFI, disconnect CMP/Hall Effect/PIP sensor. 3. Crank engine 30 seconds, check fluid level and add if required. 4. Crank engine 30 seconds while cycling the steering wheel lock to lock. NOTE: If the air is not purged from the power steering system correctly, a second customer concern or pump failure could result. This condition can only occur on vehicles with evidence of aerated fluid or vehicles that have had steering component service. NOTE: On 7.3L diesel vehicles, the fuel shutoff solenoid (on the injection pump) must be disconnected to prevent starting. NOTE: Do not hold steering wheel on stops. Page 1 of 2 1/16/2010 ...5. Check fluid level and add fluid if required. AIR PURGE WITH VACUUM EXTERNAL SOURCE - PROCEDURE 1. Tightly insert the rubber stopper of the air evacuator assembly into pump reservoir. 2. Reconnect connection used to disable ignition and start vehicle. 3. Apply 20-25 in-Hg. (68-85 kPa) maximum vacuum for minimum of three minutes at idle; maintain maximum vacuum with vacuum source. Refer to Fig. 1 . 4. Release vacuum and remove vacuum source. 5. Add fluid to FULL WARM or reservoir center mark. 6. Re-install vacuum source and apply 20-25 in-Hg (68-85 Kpa) vacuum. 7. Cycle steering wheel from lock to lock every 30 seconds for approximately 5 minutes. 8. Shut engine off, release vacuum and remove vacuum source. 9. Add fluid if necessary and install dipstick or reservoir cap. 10. Start engine and cycle steering wheel from lock to lock every 30 seconds for approximately 5 minutes. 11. Check for oil leaks at all connections. NOTE: Do not hold steering wheel on stops. NOTE: Do not hold steering wheel on stops. NOTE: In severe cases it may be necessary to repeat air purge with vacuum source procedure.

overheating after changing ,thromostat and water pump

I had a problem like this, the problem was the cooling fans behind the radiator. To check to make sure they are coming on, start the car, put the air conditioning on, the 2 fans should start immediatly, if not try wiggling the connector going to the first fan. The fan assembly may need to be replaced.

I have had my thermostat replaced twice, my radiator flushed and all my fans work properly and my car still overheats. but the catch is when its overheating i can put the vehicle in neutral and rev the rpms to 31/2 steadily and the temperature will go back down to norm for about 2-3 mins. any ideas please i have tried everything!

seems like you may have a weak water pumper, reving RPM up will help the coolant flow therefore cools engine back down.

Engine Mechanical problem
1990 Lincoln Continental 6 cyl Front Wheel Drive Automatic 55.000 miles
----------------------------------------------------------------
I have a 1990 Lincoln Continental mi 74.000 that I purchased in 2000, in 2004 it overheated and I had to purchase a new engine from the dealership and cost me a great deal of money to repair 3200.00$ to be exact,the Lincoln ran well for a while, and then on I-10 in Arizona 2006 the engine overheated again, needless to say my beautiful Cobalt Blue Lincoln is sitting in my garage, with no warning-given by the cars instrument gauges the Lincoln goes into failure.
My question is? Ive checked all the warning light bulbs and they are good, fluids are great and the car runs like a dream, its just all of a sudden the engine stops dead due to an overheat, has been checked by the dealership and several automotive techs and all are stumped dont know why. I dont want to sell it and I dont want to keep having to replace the engine. Help!

Hi there,

One of the most common things i hear is that my engine overheated but there was no warning on the gauge. this is because the temp sensor will only work when it is emerged in water, it wont work in steam or if just damp, so if you have a coolant loss causing the temp sensor to become dry it will not show an over heat problem, i would be looking for the cause of any coolant leak first as i feel that this is the root cause of your problem.

Engine Cooling problem
1998 Lincoln Continental V8 Front Wheel Drive 88000 miles

Passenge side cooling fan caught on fire while AC was on high, I quickly blew out the fire and there was no further damage that I can see. I know the fan needs to be replaced. I would like to know the best way to remove the fan.

Thanks, Leo

Hello and thanks for donating


You have to go in through the bottom to replace the cooling fan. Dissassemble the front undercarriage area, make sure to support the radiator (or it may drop out of place - this can be done with wire or strong cord - simply tie the radiator supports so that they don't move). You may possibly have to disconnect and drain the lower radiator hose. Unbolt the fan assembly and push up over the lower supports and gently pull the assembly outward and downward. You will also have to disengage several clips on the top of the fan assemble (the overflow tube and another hose).

seems like air from cumbustion is bein pumped into coolin system tried everything bleeding thermostat water pump if any1 has better remedy than head gasket please let me know maybe special way of bleeding system anything will help

Combustion gases in the cooling system is bad business. Could be the headgasket, cracked head or block

how can i find detailed instruction on how to change my therostat?

I know this is real late, but I also have a '96 Continental with the 32v Intech V8, and was astounded by the complexity of trying to work on ANYTHING underhood on this thing! lol. I was trying to get to the power steering pump, and you just about have to remove the front of the car to do so! lol. I knew someone would ask this question here, so I felt compelled to chime in now. Since I had to remove the radiator hoses, A/C compressor, radiator cowl cross-member, and all kinds of crap getting to the power steering pump, I found out the themostat housing is on the bottom of the engine! What a crock! lol. Remove the large and small hose from the housing first, remove the 2 10mm bolts that secure the housing and there it is.
When replacing the thermostat, be sure the rubber o-ring is seated correctly before tightening the 2 10mm bolts, and re-connect the hoses. Not real hard, but if you're not into laying on the ground in anti-freeze and muck, you could pay a mechanic big bucks to put it on a lift and do it. lol......Lincolndude

I have an 1995 Lincoln continetal and I have had an new thermostat replaced and i have taken my car to mechanic where he noticed an small leak in my radiator i have tried stop leaks several times and everytime i park it all of it leaks out nothing is an the tank what is it i can do to keep it from running hot

Hi there,

You will need to get the radiator repaired correctly or replaced as fill the cooling system with stop leak may cause more problems.

My car is leaking coolant between motor and transmission in the area of the flywheel. i would like to know what could be the cause of the leak in that area. Thank You for your time

It's probably not as serious as you think. This engine uses a plastic intake manifold with a valley under it. They have a lot of problems with the intakes leaking. There is also a pipe that runs under the manifold with a rubber hose on the end that can leak also. This valley has a drain hole at the rear that drains right into the bellhousing. Look at the very front of the manifold for a crack. That is a common spot.

You really need to pressure test the cooling system and you will see the leak. Look down behind the alternator.

I own a 1995 Lincoln Continental 130000miles 4.6 liter, the
problem is it is over heating. The fans are not blowing. They blow when I turn the AC on, but
after I shut it off the fans shut off shortly after that.
What must I do?

The PCM determines when fan operation is required by monitoring engine coolant temperature and A/C status. When the fan is needed, it sends a signal to the CCRM constant Control Relay Module which activates the power to the fans. Since the fans work when the AC is on, but not when it gets an overtemp signal from the Engine Coolant Temperature Sensor (ECT), that may be the problem. Or atleast a great place to start.

Where would the PCM be located?
