Question about 2004 Mercury Mountaineer

1 Answer

Check gages light on and oil gage goes from low to 60 % intermittant. Sometimes right in a row and sometimes not for minutes. Oil check at right level and color of oil good. Just changed 2 weeks ago. It just started today. 2004 Mercury Mountaineer. Is it the oil pump or just a gage issue. Have also been towing a boat with it in the past couple weeks if this helps.

First thing I would do is replace the oil pressure sending unit for the gauge.

Check gage


Check what gauge? Is that your check engine light or is it a check oil light? A lot of times if you turn a corner fast your oil gauge may signal low oil. Check your oil make sure it is at the proper level.

Why does my check gage light come on when i come to a stop


Well the check gauge light is telling you to check your gauges, because of the low oil pressure. It could be a sending unit problem, or the oil pressure really could be dangerously low. Should be at least 25psi at idle.

Oil pressure on my 1996 Dodge Ram pickup is running low even though my oil level is fine


have the oil pressure checked with an independent gage as sometimes gages in the dash don`t show correct pressure. how long has it been since the oil was changed as oil when it gets dirty it thins out and can affect oil pressure. if you don`t hear any ticking with the motor running chances are the pressure is either good or just a little low. testing oil pressure with an independent gage will tell the tale.

My oil gage at idle goes down..im scared to spend money on a oil pump..and it ticks on th right side.sometimes..but i noticed the oil gage stayed up..while driving came down just a little and it stopped...


Have the oil pressure checked at a garage to be sure A manual gauge is more accurate than a dash gauge, in ten minutes you will know the true oil pressure. Check with the dealer for the pressure specifications for your car. If it really is low at idle, your money will be well spent on a new oil pump. You might try an engine flush to clear any blockages in the internal oil passages. Often, an oil change with clean oil will help.

92 voyager check gage light


That is the oil pressure gauge not the oil level gauge. Sometimes they can act that way when the oil is thin. When is the last time the oil was changed? Try using a heavier weight oil. When engines wear they require thicker oil. What size engine does you voyager have?

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Gages


Yoyu dont mention the mileage on your Yukon but low oil pressure will indeed light the CES light when it reachs o psi. Have you checked your oil? Have you changed your oil and filter. High mileage and poorly maintained motors will eventually wear out and develope low oil pressure. A tempary cure would be to use a higher weight oil 20w50 will get a few more miles out of the old gal if indeed the cam, main or rod bearings have reached their service limit.. Good luck
