Hi Imoreno3, Just getting to this site and don't know if you fixed your problem yet. I have experienced this problem in different vehicles and it turned out to be fan cooling problem. Cars with electric fans usually have 2 fans. When the temp reaches 200 degrees or there bouts the second fan should cut on. When you turn on your A/C it should also cut on. Cars with mechanical fans it usually turn out to be the fan clutch that is bad. Don't know if this helps but I know it can be a pain in the butt and usually the fix is a simple one. Sounds like you have already exhausted the difficult ones. Joe

Thanx, for the info Joe, I will check on those pesky, have already checked the resistors and relays, and they are fine. But it can't hurt to get a second opinion from a good reliable mechanic that also does electrical work on cars, my sons cougar has the electric fans.

My mom and I have both owned cougars, hers a 99, mine a 2000.
 
We have both experienced this problem. When she replaced the rear Catalytic Converter's this problem went away and she had more power than we could handle.
 
however now as my car is doing the same thing, I got the rear converter replaced as well and the problem is NOT fixed yet. Unfortunately I am going to have to try getting the other ones out and see if that helps :S very expensive shop bill.
 
Get this checked out on your car! It's a very common problem on cougars according to my mechanic.

#50 of 153 no spark by benceturtle2

I had to replace the engine block on my 99 Cougar. after getting it all back together, I am getting no spark. I replaced the ignition coil. Still no spark. The fuel pump is working, and I have checked all the fuses and sensors and modules, all appear ok. What could be causing this and how do I fix it so that my car will run.

#52 of 153 2000 Merc Cougar & Check Engine Light/Issues by jjb009

Jan 07, 2009 (1:40 pm)

I have a 2000 Mercury Cougar and about 2 months ago the check engine light came on – the OBD-II code was P0128 - Coolant Thermostat (Coolant Temperature below Thermostat Regulating Temperature). All seems to be well with the car.
 
I live in WI so it is very cold now (Jan/09) and overheating should not be an issue; the car is producing heat in a timely fashion and it isn’t running hot. I disconnected the battery to see if I could get it to kick out the trouble code again. The check engine light went away – but came back about 2 weeks later; I ran through all of the same steps and got the light to go off again.
 
On my way to work this morning as I switched the heat from defrost to deforest/floor and the check engine light came on again and as it came on I remembered that this was the same thing that I was doing (switching the heat) when the light came on a few weeks ago.
 
Could there possibly be any connection between the heater and the check engine light?

The check engine light is it the one on the dash our the one in the head liner?
If it is the one in the head liner ( the shape of a wrench) it is telling you that it is time for an oil change, there is a spot in owners manual to reset it. If it is the one on the left side of dash is the you need to pull the heater controls out and clean them and see if that takes care of it

This morning i got in my car and was a bit cold so turned on my heater for a few min...turned it off when i warmed up...but noticed shortly later my car was not having that smooth engine flow but rather a chugging without the physical jerking of the car. Anyway shortly later check engine light comes on...drove it home no problem other then the fact that ocassionally that check engine light was now blinking . Turned car off and back on started no problem. LIght was not on till i turned around the corner and came back on...same issue...has anyone had this problem and can tell me what it is and how to fix it?

#55 of 153 2000 Cougar Alternator surging problem by protech1

Aug 10, 2009 (4:32 pm)

I have a 2000 Cougar with a V-6 that I have been having a problem with the head lights flickering, a/c blower motor surging and alternator light flickering. I ordered a new alt. and replaced my old one. I'm having the same problem although its a little better. With no load, it shows 14V. As soon as I load it up, the voltage jumps from 12 to 14 to even 16 or 18. I load tested the battery prior to replacing the alt. and it was fine. So, I removed and replaced the main wire off the alt. that feeds the batt. and still have the problem. I then, completely disconnected the wires at the alt. and I have no issues, problem fixed, but of course I cannot operate this car without an alternator. I think I may have a "bad" new alternator. Can someone confirm my suspicions or give any input to something I may have missed or not thought of. Thanks!

#56 of 153 Overheating 2000 Cougar by lmoreno3

Aug 20, 2009 (8:54 am)

I have 2000 Merc. Cougar, that the temp gauge shows it is overheating. When I check the resevoir bottle, the water is not boiling. I have replaced the radiator, water pump, coolant sensor, temp sensor, all of the belts, have flushed the engine, replaced the thermostat, even put in an aftermarket 160 degree. Still shows that it is overheating. I have also had the entire system pressure tested and it holds the pressure, so no leaks of any kind. Currently am running the car without a thermostat, but here is where it gets interesting.
When I removed the thermostat, I noticed that the hose that it is attached to is not to the upper radiator hose, like it is supposed to be, but to the lower radiator hose. The upper radiator hose bypasses the thermostat housing and connects to the back of the thermostat housing. My understanding is that the thermostat is supposed to be facing the radiator, and attached to the upper hose. Is this an error made by Mercury. Has anyone else had this type of problem and been able to solve it or had someone solve it? Please, let me know. Thanx in advance for help and advice.
