#42 of 153 2000 Mercury Cougar Continuing Problem by lmoreno3

Jun 15, 2009 (8:45 am)

Hey fellas, lmoreno3 here. I am still having the same problems with my sons cougar, As last posted. New radiator, new cap, new belts, new temperature sensor, put in a 160 degree thermostat(aftermarket). New water pump. Had it retested for any leaks. Holds pressure, no leaks. Had radiator and hoses checked with IR. All shows good. Seems water is flowing as it should. Temp gauge still shows hot after driving it for about 10 minutes at 70 mph or for 30 minutes driving at 35-40 mph, city driving. I have just bought a new aftermarket electrical water temp gauge, Exxus brand at O'Reilly's for 17.00 bucks. I am going to hook that one up and deaden the factory one. I want to see what the real water temp is. When I find out if it is overheating or not, I will post my results. Again, water does not boil in the resevoir, or boil out.
 
Post results soon.

lmoreno3 here, finally installed the aftermarket water temperature gauge, here are my unfortunate results. The car still marked hot, but only after driving it for 25 miles. The first 12 miles, it did not mark hot, only went up to about 190 degrees, with the AC off. The last 13 miles, the AC was on Max, that is when the gauge went up to the Hot mark. Stopped and looked under the hood at the resevoir bottle, and the water was not boiling. No steam coming from anywhere under the hood, and no leaks. HELP!!! what else can I check and look for, I am at my wits end.

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.

#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.
