    Default Newbie greeting - 1996 Mercury Grand Marquis LS

    Hey now!
    Newbie here. Bought a Ď96 MGM LS with less than 75k miles from original owner with entire Lincoln Ford maintenance record. Car was in excellent condition when I bought it, minus the smoke smell from the owner. Iím a big fan of American Sedans, especially the Panther Platform era. Iíll be checking in here daily to catch up on all things to gain a better knowledge of all things Grand Marq. Pictures of my rig are available on my album profile.

    Looks like an HPP. I always had a sweet spot for 95-97 MGM with the HPP option.

    Welcome!
    That car looks like it's I'm great shape.

    Check the intake to see if it has the plastic coolant crossover (front of the intake). If it does, you'll want to replace the intake before the crossover cracks and leaks.
    My '98 had 63k miles on the odometer when I bought it at the end of February, and it has the original plastic crossover intake. I have the new intake waiting to go on soon before any problems occurr.

    License plate frame says West Covina, LA area. (what dealership ?) Your car looks absolutely like new. Great find. Many original one owner cars are still hiding in the LA area. Yes, get the intake replaced if it isn't the updated version asap or it may get you stranded and you know how many people will stop to help you on the freeways. Hopefully you don't commute with it every day.

    Definitely nice to see another late Aero in Toreador Red. HPPs look good on that car.

    Thanks for the heads up! This is exactly why I joined this site was to learn the little quirks of this beast. Iíll have a look later today at the coolant crossover. Anything else you got, Iím all ears.

    I'm new to the later models. I've been around the late box body panthers for quite some time (20 years daily driving boxes).
    I haven't replaced one of these intakes yet but have done a lot of research and feel confident that I know what I'm getting into.
    Here is a video that will give you a decent idea of the problem, at about 20 seconds in:

    Some things are backward since the video is on a Mustang, and there are some steps that are different or not in the video since you have a '96.

    If you do have that plastic cross over and want to go for replacing it, let us know. We can help get you ready for it. Not sure what your level of DIY is, but if you are comfortable doing the job yourself there is a later style of this intake that offers a performance improvement (called the Performance Improved intake, PI intake). I doubt a shop would touch it since it's not a direct replacement (see 14-16 minute mark of the above video for the biggest problem). I'll be installing a PI intake since I do all my own work an have the tools.


    I see you have the automatic temperature control. If it has issues where it only blows out the defrost vents or doesn't seem to blow out of where it should, it needs 4 o-rings replaced. Some great info from sick88tbird: https://www.youtube.com/watch?v=beSV_jZxR5o Check out my recommendation in that thread on '03+ retrofit for easier serviceability.

    Make sure you take it on at least a 20 mile drive(not in stop and go traffic) before a smog check. It has 4 cats if dual exhaust. Got to get those hot before the smog check. Spark plugs are probably original. Put the same type as it came with back in. The back ones are a bear to get to. The small plastic engine cover over the TB if it is still there, mechanics love to break and never tell you they broke it. It has a hold down bolt on the passenger side. There might be a overdrive lock out button on the shifter. Green light on the dash when shifter button is pushed in. I drive mine not in OD at speeds 45 or under. It saves the transmission OD band. If you don't have that button, It might be only on police cars. Keep the leather seats conditioned. If kept outside, the sun will dry the leather. Your car looks garage kept. Check with Ford to see if all recalls have been done. They will need the vin number.

    That's clean! Digi-dash to boot! We had a 95 that had 280k on it when I got rid of it.
