Question about 1997 Lincoln Mark VIII
Posted by Anonymous on
Friend, your only problem is a radiator cap that holds too much pressure and when hot enough will blow some coolant out. You'll never see it because it just dissipates from being hot. Swap out your radiator cap for a lower pressure one. I had to do this myself and the problem stopped.

yes...they do program the computers to come on or give a "service engine soon" light so that you will bring them back into the dealership....if you have access to an obd2 diag tool you can reset the codes yourself

'coolant leak but hoses are fine'...? If it has a leak, where is it coming from?
your possibilities for overheating are varied on a Mark viii, things to check are the coolant fan-does it come on when you let it idle for a long period of time, NO air conditioning on? If not, your VLCM (variable load control module) is bad, it is located next to the suspension compressor, passenger side fender under the intake filter. Check fuses and relays too, you might luck out and find it is just electrical. That fan takes a lot of juice (60 amps!) so make sure your electrical system is in good shape-even the 130 amp alternator you have is barely marginal, I have a 200 amp in mine, it is a good thing. Water pumps on these are easy to replace, one of the easiest I have ever seen, so consider it. Also a Cobra pump is a better alternative to the stock pump.
there may be air in the system, these cars are prone to this and have to be filled properly after servicing the cooling system-the front of the car should be a little higher than the back, and after filling the surge tank, remove the cap to the crossover tube (1/4" drive rachett) and start the car, let it run and fill at the crossover tube until it dribbles out of the top-screw on the cap, drive it, and if necessary, check it after it has fully cooled down to see that it has no air in it. Your surge cap may be defective, and people HAVE installed the thermostat upsidedown, so you may have to double check that. And, id you have a leak, it needs to be fixed-the system should hold pressure when it reaches operating temp, you can check this by squeezing the top radiator hose, it should be impossible to collapse. there's always the possibility of a blown head gasket, but it would run badly, smoke out the exhaust, you'd find oil in the coolant or coolant in the oil-hope that is not the problem, these are a pain to do since it is a DOHC engine.

SOURCE: 2002 Lincoln LS V6 Overheating
when the car overheats, is there still water in the radiator?
If there is water in the radiator and the car overheats, then it means there might be some dirt or blockage in the radiator or condenser.
When the car is on the motion, air passes through the front and assists the fan to cool the engine. There are situation whereby air doesn't have free flow because of blockage in the radiator and condenser. Dust and debris can cause blockage. If this be the case, have your radiator washed thoroughly and cleaned.
If there is no water in the radiator when the car overheats, then there is a probably a leakage from the water pump. Or maybe your fan isn't blowing properly. The fan might be blowing weak air.
The above are what could cause your engine to over heat.
So start the check from the radiator. Poor water into the radiator, wait for some minutes, look under the car and observe if water is going to leak. If there is a leak, it might be from the water pump or a leaking hose.
If water from radiator has no leak, have your radiator washed and clean the condenser has they might block air that is suppose to cool the engine.
Also, make sure your fan is blowing properly or well enough to cool the engine.
Make sure you have the above checked thoroughly as they are the major causes of problems like this.
This overheating problem could lead to a burnt gasket and this can dry the engine oil which will eventually knock the engine. So have this problem fixed to prevent further damage that will cost you more money.
Lastly, remove the hose that connects the radiator to the engine, water from the engine will come out. Pour water into the radiator, the water will flow through the hose down to the ground. Do this severally. Now connect the hose back to the engine, pour water into the radiator. Start the engine, the water in the radiator will reduce, add more water till radiator is full.
In summary, the major cause of over heating problem is from the radiator, fan, water pump, blockage in the hose, and dirt in in/on the condenser. These are area you need to concentrate on.
I forgot to mention that the acceleration meter or engine meter on the dash board shouldn't be more the 5. It should be below 5. If it is above 5, it can cause overheating. I hope you understand what I mean.....
