odd noise from 03 explorer	Sign In

03 explorer v6, xlt auto trans, it also has auto 4 wd i have an odd noise when driving , it is best to use the tack to describe when it makes this sound, im showing my age but do you remember the noise you got from your radio on am from the engine, it does at 1700 and 2100 rpms under a load does not matter what gear, it will not make the sound standing still, i checked the air intake there were no obstructions air cleaner relatively new,all fluids full , with the radio on or off , any help is appreciated thx

always go back to the basics

Hi, Obviously the section is called Funny Noises for a reason. Perhaps this is a belt or pulley bearing whine. I'm forever ruling these out as some can be very strange. Try spraying some WD-40 on the belt's friction surface and see it the noise about instantly goes away. If so I'll blame the belt and if it looks real good and is tight enough most will behave long term with use of silicone grease on the belt.

If not change - see if you can hear any busyness at the belts and pulleys. Hard to tell which one sometimes. If this seems like the possible direction you can listen to bearing with a mechanic's stethescope or listening rod. Those are real attractive when shot thru your head so use all caution.

Another that can be elusive is the exhaust sytem. There are lighter metal heat shields tack welded around converters and spots on some pipes that can make some strange noises. Some you can find by just tapping on the exhaust with a rubber hammer when engine is off or just bump around and look at general condition of those. That sort of thing would be RPM and load related but so can belts and pulleys. Keep at it,

T
