SOURCE: 1993 Mercury Cougar power window, driver side, will not move

the power window motor needs replacing. check at a salvage yard for a door intact and remove the panel use a hammer and chisel to remove the large rivets that hold the motor in place and cut enough wire so you can test it with a battery before installing in your car to install in your car you will need some small nuts and bolts with lock washers and put a little lock tight on the bolts so they don't come loose Good Luck!

SOURCE: can you bleed the water cooling system on 1999 mercury cougar

This is extremely important on some cars, for instance my BMW. 1. Have the car parked in a slight uphill slope. Make sure there is enough coolant in the expansion jar.
2. Start the engine and wait for the thermostat to open (upper radiator hose becomes warm).
3. Open up the radiator bleeding nipples slightly with a large screwdriver (bleeding nipples normally made of plastic with a '+* for a screwdriver to fit, at the highest points in the cooling circuit).
4. Allow air bubbles to fizzle out until you get a steady stream of coolant leaking out, use rags to capture leaking coolant.
5. Then close the bleeding nipples, switch off the engine and wait a few minutes for pressure to come down.
6. Open up the cap on the expansion vessel carefully and fill just below the "hot" marking.
7. Check levels again after a few miles and refill further if needed.

SOURCE: my 1997 mercury cougar is running on the VERY high side of hot

check to see that the electric fans are turning on when they are supposed to, and make sure the coolant is full and that the rad cap is good. Bad radiator caps are one of the most common overheating causes

I have a 2002 mercury cougar. After the coolant gets to operating temp both my high speed fan and my low speed kick on and stay on for a long period of time sometimes they dont kick off, do i have air in...

It could be you have a faulty radiator fan relay. There could be issues with the thermostat or thermostat housing. The old Cougar thermostat housings weren't built very well and tend to malfunction. Check the by-pass hose from the heater to the intake manifold after the car is warmed up with the heater on to make sure it is hot and coolant is actually passing through. I would just replace the thermostat, relay, and housing and see if that fixes it first. If these things haven't been changed in the last 10 years then they are due for a replacement. Here's a website that has all the parts and good pictures with descriptions:

Where is the obd2 plug in on an 1993 mercury cougar ar7

Your 93 does not have an OBDII plug. Those didn't start until 1995 or 1996, depending on the vehicle. There is a diagnostic plug under the hood. They moved them around a bit but it is usually on one of the inner fenders.

How to put a thermostat on a 1985 merecury cougar

You'll need to remove the upper radiator hose from the thermostat housing. Unbolt the 2 bolts holding the thermostat to the intake manifold and remove the thermostat housing and thermostat. Clean both mating surfaces and install the new thermostat with a new gasket, reinstall the radiator hose, fill with anti-freeze and check for leaks.
