Rear struts-2002 Cougar by finnigan
Oct 14, 2007 (10:39 am)

Has anyone replaced the rear struts on their Cougar. I've got a bonking noise from the right rear under bumps and I think the strut is to blame. I pulled off some interior bits and pieces to check out the strut tower and found about no space to tighten up the strut. Does anybody know if a Ford specific special tool is needed or does the strut simply screw into the tower. Thanks!

egr flow insufficient by tc8ball
Oct 15, 2007 (8:32 pm)
Reply
My daughter has a 2000 cougar v6 auto now with 130k.
She is in medical school, and i take care of the car.
Has run well, she aint the most mechanical, but i dont think more than normal problems.
yes, i replaced the radio, and the sun roof wont open any more, but has been good transportation. sounds good with an after market stereo, and who really needs sun?
 
my problem now is / are two.
1 engine light is on, and code reader sends back P0401 EGR flow insufficient.
2 temperature guage stays at minimum.
 
a year ago, it was running bad,(uneven idle, stalling, racing engine... always started) and though the codes said oxygen sensors were not right, the problem cleared up with replacing the coolant sensor.
 
I have checked the egr valve, and it opens, no holes in the diaphram, and the exhaust tube is not blocked. if you close up the holes in the manifold, the egr opens and closes, and will stay open at a constant rpm (~2k).
 
now the egr vacuum passes through one vacuum solenoid, but the egr itself has only a diaphram and exhaust tube. there is no device to sample the egr flow directly.
 
does anyone know what other sensors are involved in deciding how much egr is the right amount.
is there a second temperature sensor, and where is it?
i did replace the temp sensor again, and nothing changed. (just wishful thinking).
 
I reset the computer, and the light stays off about a day, during that time, no codes are in the car, and there is no freeze frame data.
im running low on $ as just did rear struts, front lower control arms and stabilizers, wheel bearings last year.
(Pittsburgh pot hole are the best)
 
thanks for any help.

i just did this on a 2000 cougar.
not too bad a job.
in the strut tower, there are 2 10 mm screws that hold in a top mounting plate. there is a pinch bold on the bottom, thats easy to see and get at.
 
you need to disconnect the stabilizer from the swing arm.
 
loosen, but dont take out the 2 10mm screws.
 
loosen and remove the pinch bolt.
 
support the control arms so they dont drop when its all loose. but it needs to be able to fall away from the strut.
 
you will need to compress the spring/strut to get it out of the tower, and away from a travel limiting tab on the frame.
 
once its out, you need to compress the spring, remove the top bolt, and pull the spring off.
 
your half way there..
 
keep the spring compressed, and reassemble it and the top plate on the new strut.
 
keep the spring short,and put it back in the tower.
 
start the 2 10 mm screws, but not all the way tight.
 
reposition the strut and push the lower knuckle back onto the new strut, and replace the pinch bolt.
 
make sure the ends of the springs are in the right place, and release the spring.
 
recheck all the bolts to torque specs, and your done.
 
all through this, you have to take care not injur your brake lines or abs sensors .
 
bolts are easy to get to, top ones need some extensions.
spring compressor is the key, needs to be compact enough to get into the tower for re assembly. there are some available that use a single screw. the cheaper ones use 2 screws with hooks on both ends, and take up too much width and height in the tower.
i was desperate, and used steel cables to keep the springs compressed after i reassembled the thing on the bench. then loosened the cable bolts after it was together. it worked, but... dont be a putz like me, go rent the right compressor, then its a relatively easy job.
 
good luck, be careful.

This may sound like something you may have already checked into. Though you have replaced the a/c and you say that it doesn't blow any cold air even right from install correct. Is the ac clutch engaging. If the clutch isn't engaging then its not a leak its an electrical problem. In my experience most of the time the problem with the a/c's in fords, especially mustang i know this to be true, is the low pressure switch located on the condenser. You can usually cross the connection to get the a/c clutch to turn on.If that is not the case then I have a copy of the Ford Shop Manual for a 2000 cat which should be of great help. My friend has a similiar problem with his. Then his next problem was that his a/c would only blow on the highest speed. Thats when I got the manual and wiring diagrams to fiqure out where the blow motor resistor was.

Speedometer and Odometer Not working by supercat1
Nov 08, 2007 (5:47 am)
Reply
Ok, I am driving down the road and my speedometer stops working. All other gauges are working. So I keep driving the car. Seems to be running fine. Two days go by and the odometer stops working. Still driving the car, the gas light goes on with ¼ of a tank of gas. Not usual. Driving the car and all of a sudden on the Turnpike it just stops running. I turned if off and on she went without further incident. Does anyone have any idea other than me needing to just suck it up and pay for someone to fix it? Could it be a fuse? The car has 196 thousand on it so I really hate to put money into it! HELP!
