Mercury Mountaineer

The IAT sensor measures the temperature of the intake nmanifold. The ECM uses this sensor reading to set injection timing and adjust the air-fuel ratio. If the fuel mileage and power output of you engine seem low, some owners have found improvement in EGT, fuel economy, and power after cleaning carbon from the IAT sensor in at the rear of the intage manifold. Engine with exhaust brakes are particularly prone to IAT sensor fouling because soot is blown back into the intake during valve overlap.

The only tool you need is a 3/8" ratchet with a 6" extension and 13/16" socket. View of IAT from above battery Closer view of the IAT sensor The IAT sensor is found on the driver's side of the engine, almost at the back of the intake manifold. Unplug the electrical connector from the sensor. You will need to spread the connect tab away from the sensor body to unplug the sensor. After the connector has been removed, use a 13/16" deep well socket, 6" extension, and ratchet to unscrew the sensor from the manifold. Photo of a dirty IAT sensor The sensor on the left had 20,000 miles on it, and it was covered with soot. After a shot of carburator cleaner, you can see the sensor element inside the cage. Screw the clean IAT sensor back into the manifold, torque it to 10 ft-lb, and reattach the connector. Photo of a clean IAT sensor

on the dash there should be three buttons info, setup and reset one of those you press a few times and should show reset oil

First turn the key to the run position (dash lights on and gauges on) you do not have to start the car. Now look for the "info" button. Push the info button until you see "push set for system check". Then push the "set" button After you push "set" you will see the oil life setting. Mine was at 0% life remaining. Now push the "set" button for 5 to 10 seconds until you hear a beep. Then the oil life will show 100%. Start the car and the oil change warning should be off. If not just retry the procedure. Where i made my mistake was in not holding the set button down long enough. Both the info and set button are in the center of the dash near the radio.

The nozzle of the sprayer may be plugged. Try sticking the end of a pin into the hole and working it around. Pour hot water over the nozzle and hose and tap them sharply a couple of times, then run the squirters.

If you press the stick and don't hear anything then your wiper motor is faulty or you've blown a fuse.

Also-humming noise when push to spray, maybe motor ok but I used hose to spray in water tank and hose sprayed lines to see if all going threw. maybe line clogged.

I'm thinking that you're talking about your rear "trunk" door. If so, from my understanding, you cannot open it from the inside. To double check this, you can look in the owner's manual for your vehicle.

the cost of new brakes is irrelevant.... However, what you have to pay is important and its a lot if you take it to the dealer.

you need an alignment, badly....or your bearing snapped. call a mechanic, and tell them your vehicles' symptoms. they'll tell ya the same thing i just did

If it is the same as a2004, you end up removing the whole unit. Screws on tailgage side of lenss.

THIS WAS MY QUESTION, BECAUSE THE 3RD BRAKE LIGHT WAS BLINKING I THOUGHT THERE WAS A MAJOR PR0BLEM,TURNS OUT IT WAS THAT BOTH BULBS WERE BAD,CHANGED THEM AND EVERYTHING WAS FINE

According to the 2000 Mercury Mountaineer owner manual :

With engine oil filter change :

The 5.0 L / 302 cubic inch V8 engine takes :

( 5.0 U.S. quarts of 5W-30 )

According to the 1997 Mercury Mountaineer owners manual :

( 13.9 quarts / 13.2 liters ) for the 4R70W automatic transmission ( rear wheel

drive and all wheel drive )

** that would be for the entire system , transmission , converter , lines , etcetera **

According to the 2005 Mercury Mountaineer Owner Guide :

The 4.0 liter V6 engine takes ( 5W-30 )

The 4.6 liter V8 engine takes ( 5W-20 )

On a 1997 Mercury Mountaineer :

In the Power Distribution Box ( which is " live " ) located in the engine compartment

( the # 3 maxi fuse is a 20 amp fuse for the fuel pump relay and RAP module )

* also in the PD Box , the # 6 relay ( one of the large relays ) is the fuel pump relay

* the fuel pump shut off switch ( inertia switch ) is in the front passenger footwell , by ( or behind ) the kick panel

Well, it holds about 6 gallons, letting it role on for about 7 hours with a full tank hope i helped

===========================================================

According to the 2006 Mercury Mountaineer Owner Guide :

The fuel tank holds ( 22.5 U.S. gallons )

( Helpfull )

On a 4.0L: 1-4-2-5-3-6

On a 5.0L: 1-3-7-2-6-5-4-8

In the front of the engine compartment , on the passenger side , inside the

engine air filter housing

if you go to any auto parts store they have repair manuals that show you how to take apart and put back together your specific vehicle, has photos. would find mountaineer in a ford explorer book. cost about $20, but are worth it.

On a 2005 Mercury Mountaineer :

All Wheel Drive ( AWD ) has engine power going to all 4 wheels , all the time ,

and doesn't require any driver input

you need to change your thermostat

replace it.

The owners manual shows 10.3 quarts , but that is for the entire system : Transmission , torque converter , lines , cooler etc. My Haynes Ford Explorer repair manual shows the 5 quarts for the 4R70W transmission with the 5.0 L ( 302 cubic inch V8 ) and ( 4 quarts for the 5R55E automatic transmission ) to drain and refill the automatic transmission pan , but you actually add slowly and use the dipstick to determine the transmission fluid level from what I understand

The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

A cheaper and more effective answer is to go to the Ford / Mercury website and download the PDF owners manual. I own a 2000 Merc Mountie and the file was about 2.3 mb which took about a minute worth of downloading and abracadabra the information is there. Since you're already at your computer, you're halfway there. :> Go to Ebay and purchase an original owners manual for less than 10 bucks. The book will have diagrams on all your fuses. I just recently went through the same thing.

The first model year of the Mercury Mountaineer sport utility vehicle was 1997

Did you mean 2005 ?
