lmoreno, sounds like your gauge is bad, OR you need to replace the resistor that is built into the fan assembly. It's a 50 dollar part. The dealership will charge 150 to replace it, but if you have simple tools, a good Jack, a blanket, you can do it yourself in 2 hours.
I did it, I got under the car, pulled down the fan assembly just enought to remove and replace this resistor. Don't know the part number offhand, but I have it listed on the NECO Cougar forums.

Am going to try that, had one of the three catalytic converters changed and that helped out, can go farther now, before it starts to show hot. Where did Ford/Mercury get the idea that three catalytic converters would be better?

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.

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 156 2000 Merc Cougar & Check Engine Light/Issues
Jan 07, 2009 (12:40 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?
