      You either have a bad charging system or a paracitic drain (power being used when the ignition is turned off). Have it checked by a shop to determine the state of the charging system, if you notice the battery light on at all times, the vehicle is not charging properly.

    Do you get better gas mileage when you nitro fill tires?
    • CVO
      1/18/2012 CVO
      Not really, when using nitrogen as an inflation gas, the composition of nitrogen increases from
      79% to near 100%. The use of nitrogen based on its ability to better retain air over a period of time.

    A mechanic told me I have 2 broken coil springs, left front and left rear. He said he'd recommend replacing all 4 coil s
    all 4 coil springs because they are the same age, cost $1,000. He said the broken spring could puncture the tire and cause me to run into the ditch. Should I get this done asap or is it OK to drive car and is the cost reasonable. Thank you. Also I have a ...

      I am having a hard time believing that you have a broken coil spring on both front and rear. The odds are against this and I think you may have one broken spring but he wants the $1000 job so that is why he said that one in front and one in rear is broke. I simply would have to see it to believe it and would place my bets that I am right. Yes, in theory you could have a spring puncture the tire but I have never seen it happen. I would get a second opinion and do not tell the second shop about the first shops diagnosis.

    Why is my belt squeaking?And now theres knocking sound? Alternator or serpentine belt? Help!!!
    My altanator went out in my car about a month ago.I just got it fixed yesterday but now(I think my serpentine belt)is squeaking really bad. Then the following morning I started my car and not only was it squeaking but it sounds like something's knocking in there now ...

      Could it be cuz my car wasn't driven for so long or cuz it's cold outside? - I dont think so, my car was garaged for 2 months and when i started it, it started and ran like a dream.

      For your squeaking belt...You replaced your alternator but did you replace your belt. If your belt is still ok, check belt play for looseness, maybe the guy who installed it didnt tighten it. There should be at least half or less than half an inch of slack. This is usually solved by moving the tensioner back to tighten it.

      Applying an aerosol belt dressing is as easy as it seems. All you need to do is aim and spray. The catch is that you have to do it with the engine running, so be very careful!
      You need to direct the spray toward the inside of the belts, the part that touches all of the metal pulleys. Since the belt is moving, you only need to find one good location to spray from. Spray the entire length of the belt by holding the nozzle down for 10 seconds or so while the belt goes by.

      Safety First!

      •Work on level ground with good footing so you don't lose your balance.
      •Don't wear hanging garments that could get caught in a belt and suck you in with them.
      •If you have long hair, don't lean over the belts close enough to get your hair caught.
      •When working in a running engine bay, always concentrate on the job and avoid distractions. If there is too much going on around you, wait until you can do it calmly.
      Remember, this is a temporary fix. Your belts are squealing because they're worn or loose, and should be properly repaired asap.

      For the knocking unable to verify this since im online but are you sure its coming from the belt.pulley area?

      I believe that you have a bad timing belt idler pulley which is very common on this 2.0 but it has to be confirmed by a good tech with a listen. You cannot go ahead and change the pulley and timing belt on my advice alone even though I have a good chance of being right on. Every time I go after a noise on a Mystique or a Contour it turns out to be the same pulley in by the timing belt on the bottom that is wasted.

    How Do I Change The Spark Plugs

      Believe it or not, the easiest way is:

      1. Remove the plug wire by pulling it off carefully, grasp it close to the end. You can also buy a plug wire remover which is available at any parts store.

      2. Using a SPARK PLUG wrench (available at any parts store) - remove the old plug.

      3. Insert the new plug.

      4. Tighten, but not TOO tight.

      5. Push the plug wire back on.

      6. Repeat 1-5 for the other 7 plugs.

      You might find it easier to access some of the plugs via the holes above the tire wells. From the side of the vehicle, you'll see a hole near the top of the tire well. If you change the plugs, it's best to replace the wires also.

      NOTE: The wires and plugs on Grand Marquis are rated for 100,000 miles or more with proper maintenance.

      NOTE 2: Unless you area good mechanic, changing the plugs can cause you more heartache than the price of having a professional do it for you.

      You should remove the coil-on-plug units from spark plug. And then loosen spark plugs 1/4 turn and remove any dirt or foreign material from spark plug areas of cylinder heads (6049) with compressed air.

      Remove spark plugs .


      Follow the removal procedure in reverse order. And then tighten spark plugs to 9-20 Nm (80-177 lb-in).

      You'll have to relieve the fuel pressure and remove the fuel tank. Remove the locking ring by turning it counter clockwise. Pull the module cover out to expose the locking tabs. Squeeze the tabs together and remove the pump module. I suggest a repair manual if no one has a video. It's about a 2.0 hour job for the shop.

    Gas smell from the trunk

    • 92bimmer

      have you noticed any gas leaking on the ground on the side where you fill the car with gas? Open the trunk and see if if filler tube is able to be seen from there, maybe by removing a panel in the trunk to view it. That would be the place to start looking.
    • RC
      3/17/2010 RC
      Sounds like it could be the fuel pump, tank, lines, or the filler tube. I hope you're not driving it... This problem needs to be fixed asap.

      Could be a filler tube? My guess would be a bad seal on your fuel pump if it is under the trunk. It could also be a leaking line or the smell could be a hole in the tail pipe or muffler that creates a similar smell. It could also be a rusted hole in the gas tank?

      Good day,

      I have a diagram and troubleshooting steps in this forum, i used it for my Civic, im quite certain its the same as your villager, you need to locate the fuse panel and check the fuse to the wiper motor, it may have blown and needs replacing

      Also, does it happen on all Wiper modes?

      Just scroll down until you see the pics

    Does sea foam really work?
    What is the proper use for this product? Can you just add this to a full tank of gas? After using will you get better gas mileage?
    • texastough
      11/27/2011 texastough
      Does it work? Yes. It does what it is designed to do. That is, clean your fuel injectors. Over time, the tips will build up with composites and other things that retard the flow of fuel through the injectors. Sea Foam (and other brands, i.e. Chevron with Techron) remove this build up, thus increasing the flow of fuel out the injector.

      Can you add it to a full tank of gas? Possibly. Every formula is concentrated for a certain amount of gas. Pouring a 6 gallon concentrated mixture into a 12 gallon tank will dilute the cleaner and render it mostly useless. Check the bottle and add to the specific amount of gas it was concentrated at.

      Does it give you better gas mileage. Possibly, and no more than 1 mpg. Depending on the amount of build up, yes, it will help alleviate some blockage thus allowing your engine to receive the proper amount of fuel per combustion cycle. However, it is rarely noticeable and usually never more than about one mpg. Some will claim more, but there are so many factors (mainly your foot ;) ) that affect that number.

      I don't buy any of the claims. Gasoline has sufficient additives already in it to keep injectors clean. IMHO

      Buy the battery that; fits your vehicle and has the best warranty - that you can afford.
    • HouseCallAuto

      It's all about the CCA (Cold cranking amps). The higher the CCA the better the battery and usually the higher the price. The heavier the battery gets carrying it is the better battery.
