SOURCE: how can i change fuel filter in my grand marquis

you will need the proper Quick Disconnect tool, Look on the Frame rail for the filter, remove filter from the spring type retainer, remove the safety clips on the lines but not remove them completely, insert the disconnect tool & push into the fitting of the fuel line, push line & tool into eachother then pull filter away from line, if not done properly you will have a big problem putting the line back on

SOURCE: Noise when making a slow speed tight turn.

noises during slow tight turns are usually CV joints going bad. A way to check, is to jack up one front wheel, set the parking brake, and put the car in drive without pressing the gas. Turn the wheel to both extremes, and listen for the noise. Repeat with the other front wheel (set the first one back down) and listen. Whichever makes the noise, is the side you need to change.

There are several possibilities that could be causing your problem.

  • Low on power steering fluid
  • Bad steering box
  • Bad tie rod end
  • Bad ball joints
Assuming the power steering fluid is full, bring the car to any brake shop or repair shop that does front end alignments to diagnose the problem further. I hope you find this points you in the right direction. Thank you for using Fixya! Greg

SOURCE: I have a 98 grand marquis it keeps overheating I

This could be a broken head gasket, cracked head or block.

Pull the thermostat back out and you should be able to see water flow through the radiator. Make sure the water pump is working.

I have a 2000 mercury grand marquis and there is loud whining noise that sounds like its coming from the air filter hose . What could this be?


Have you removed air filter housing cover and checked condition of your air filter ? If so, then remove air housing and hoses up to the throttle and see if noise is still there.
You may have loose intake clamps, check all and tighten.

The air flow system is making a load humming (mooing) sound. I have a 2001 Mercury Grand Marquis and would like to know what is done to stop the noise and how much does it cost to repair.


The air intake ducting (all the black hose plumbing coming from air cleaner box) may have a loose connection somewhere. Check all clamps and sensors attached.

When coming to a stop , coasting down the engine makes hum sound and then dies, starts OK after that and goes on , very intermittent


This is not going to sound possible but it happened in my 1994 Crown Vic too. If you have traction control part of the system controls an air valve in the air filter intake area. When the traction control senses a difference in rear wheel speed it chokes the engine so you don't spin the wheels.
Your sensors must be dirty or the emergency brake pads are covering the sensors with brake dust. You need to have someone check the rear brakes.

You motor will produce that hum as air is choked off by the traction control.

When i try to crank it its make the noise like it want to crank but never runs i already change the feul pump and filter it still isnt cranking


Nothing to do with fuel/filter, either the battery or starter is at fault ,if it does not cranck over, if the engine turns over normally but does not want to run, thats a different story.

Car making loud humming noise from the air intake or air filter when idling ,a/c on and pressing gas petal.


the idle air bypass valve is making noise and resonating through the air inlet the valve needs to be replaced there is also a revised hose to the valve to reduce noise if it hasn't already been replaced

99 Grand Marquis won't stay started when engine cold.


Here is the most common cause of this stall, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Fuel issue


Either has the common plastic intake leak or faulty mass air flow sensor by air filter, cost $25 used so the best place to start and make sure you do not have any loose connections or cracks in air intake hoses
