Question about 2005 Mercury Montego

Open Question

2005 Mercury Montego: outside air temperature is inaccurately reflected on the instrument panel. 2 questions. 1) is there way to check calibration or "working order" of the ambient temperatur sensor before replacing? 2) If sensor needs to be replaced, how to find the correct location to replace the sensor? I have taken a look and haven't found it yet (been told it is in upper left side of the engine compartment. Thanks, Todd

SOURCE: Change the oil on a 2005 Mercury Montego

Go to a automotive store and tell them you have a 2005 Mercury Montego and what engine it has if there is more then one model and get an oil filter and the oil. Put the car up on ramps and secure it making sure it won't roll back or fall while you are under it. get under the engine and look for the oil pan which should have a bolt in the bottom of it where you can drain the oil. Drain the oil in a proper container and then put the drain plug back in the pan. Then find the oil filter and unscrew it and remove it.. It could be full of oil so watch out and make sure the pan is underneath the filter. Wipe the base where the oil filter screws on and make sure the gasket from the old filter is not still on the engine. Get your new filter and take your finger and put it in one of your new containers of new oil and spread that on the gasket of the new filter. Screw on the filter until the gasket touches the base and then turn only a little more then a 1/4 to 1/2 turn tops. Do not over tighten the filter. Find out what oil the vehicle needs (probably 5-30) and look for the oil cap on a valve cover under the hood. It probably takes 5 quarts but check for sure in your manual or ask when you are at the automotive store. Put the oil in and put the filler cap back on. Now go start the vehicle and make sure you have oil pressure by either the oil pressure guage showing pressure or the oil pressure idiot light goes off and while running check under the car for any signs of leaks. If no leaks then back the car off the ramps and shut the car off on a level surface. Let it sit 10 minutes and check for leaks underneath the car and check the oil dipstick to make sure the proper level of oil is in the engine. Then you are set.

Always check your air filter when changing oil to make sure it is clean as that helps your engine run better and you save gas in the process. Good luck

It is also best to change oil when your engine is warmed up as well.

SOURCE: Mercury Montego won't start. Started 10 minutes

You could check the Inertia switch and see if the fuel pump is cut off.
If that is Okay I would disconnect the battery and see if the system reboots.
If it starts after that, go to Autozone or Oreillys for a free scan.
If it does not start, then try putting in the security code if you have a keypad. If no keypad, then try your other carkey, your ID chip may have died.

SOURCE: My mercury Sable 2003 in blowing all cold air.I

replacing the thermostat on an otherwise good running car is not going to fix a heater, now you know that. yes you are going to have to pull the dash, and it is a complex procedure, to swap the core. i would call a shop which does a lot of heater and A/C work as if you pull a lot of dashboards you get good and fast at it. stay away from a dealer

Where is the map sensor located on a 2006 mercury montego?


It doesn't have one , has a mass air flow sensor .
Mass Air Flow (MAF) Sensor The MAF sensor uses a hot wire sensing element to measure the amount of air entering the engine. Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above the ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration.

Ext. temperature gage doesn't work on mercury montego?


Okay, the first thing is this may just be a bad sensor, the sensor is located on the front of the truck behind bumper area,Make sure the sensor is not unplugged or is touching the condenser or radiator. the sensor should be mounted so that it is not touching anything, the tip of the sensor is what reads the outside temp,
If the sensor is mount correctly and is plugged in then replace the sensor with a new one and that will solve the problem. good day.

I have a 2005 ford freestyle the ac is fully charged the rear works great the front passenger side is ok but the drivers side is warm about 20 degrees difference between the drivers side an passenger


there is a door that directs cold or hot air behind the dashboard in order to make the passenger's side colder or hotter relative to the driver's side.
The a/c door servo may be bad, or the temperature settings for each zone are not balanced.
