Yes, at least half of the exhaust is coming straight out of that gap without passing through the muffler. As you've noted, this leads to an increase in noise (or music, depending on your taste). To my eye, that looks like a hassle to fix on your own. There appears to be the rusted remnants of two bolts holding the Y-pipe to the passenger side muffler and ...

It takes a long time for the heat gauge to register as anything but cold, about 10-15 minutes. This is almost definitely a stuck open thermostat. The engine should reach operation temperature within 10 minutes, meaning middle of the gauge. You should see it start moving up within about 5 minutes

It sounds like your Passive Anti-Theft System (PATS) security system has locked you out, but I bet you figured that out already ;-) I found some instructions for resetting a Mercury Mountaineer, and would imagine it should work for your Montego as well. A symptom you should also be looking for is whether the flashing red light continues to blink at double ...

Having owned a 97 Taurus which is a Sables cousin a common problem is the vehicle speed sensor. If the sensor completely fails it is easy to diagnose. Mine slowly failed over a two week period during which time it would shift into nuetral, have eratic speedometer readings,and would shift up or down at odd times or work perfectly fine. The coolant resevoirs ...

I've heard it many times, but never seen any proof. See the question and my answer to this post. I have never read about it in any of the Factory Service Manuals I have been through, so I shelve it up as false. I think the idea is that new fluid, with all the fresh detergents, shock dirt and debris loose and cause problems. Again, never seen it happen.

There are several things to look for here: Localize where the fluid is actually coming from. Doing this will allow you to take the next step. Ensure you put all of the hoses back in place correctly. It is easy to get one cocked in the wrong direction, where you think you go it right, but you don't. Check all of them to make sure they are completely in ...

I would bet you're right about having to disconnect hoses, but don't know for sure by just looking at an image on Google. If you do have to disconnect the A/C hose, you should take it to a shop which will be able to completely remove all of the refrigerant from the system prior to opening it up. After you get the hose off, you'll need to get a new drier to ...

Resistor packs/Thermostats can and do fail. Your one lasted 10 years. This would not be a bad performance for non-safety critical part.

It seems your multifunction switch is probably bad. It should be fairly easy to pull this switch to inspect it. I found these instructions to gain access: The turn signal canceling is part of the function of the 'multifunction switch'. This is a switch mounted on the steering column by 2 screws. Once you take the covers off, you can see the ...

It is difficult to pinpoint the exact reason for your idling issues without further information or knowledge of your Mercury Sable. However, a common cause for idling/stalling is a perished/broken/cracked/disconnected vacuum line that results in a vacuum leak. Vacuum lines are essential in maintaining engine idle. The fix would involve identifying any ...

The adjustment screws should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support. Once you have adjusted the bulb, see if the dark area goes away. It could be connected with the alignment.

It seems highly likely that it's the Blower Motor Speed Controller. It's a known problem on the last couple generations of this platform and a redesigned part has been issued (8W7Z-19E624-A). It's possible that it's just a bad blower motor, or both the blower motor and controller could be bad. Good info here. The blower motor and the controller are in ...

If you can get at the blower motor turn it on and put your hand on to see if you can feel the motor running. You may be able to feel it try to start if you have someone cycle the switch while you touch it. There is the chance the fan wheel fell off (this usually generates a racket) or a chipmunk has it packed with acorns. If you can't feel the motor start it ...
