take it easier on the clutch as your reversing
Burning Wires.
burning rubber
it is most likely the brake calipers sticking, as I recently had this problem on my 2007 dodge grand caravan. They did not do it all the time, but would stick out for a brief period of time after braking, thus causing the burning smell, and then shortly after retract far enough so that there was no longer cantact, and therefore, the burning smell then went away.
That smell is probably your clutch burning out.
It depends what odour you mean. It's just a word we use to describe a particularly sharp smell. If you are referring to a person's smell, it usually is caused by bacteria breaking down sweat This is what causes that odour.
Several thing scan cause a burning smell from a car A/C. One cause can be that the compressor is burning up. Another possibility is a wiring shortage.
Friction from excessive braking causes heat, thus the lubricant on brakes release this burnt smell.
The clutch is slipping and needs replaced.
Sometimes when parts are new, they have coatings and etc. that will smell when parts are warm. For example, alternator windings are coated with a electrical varnish. When the alternator is charging, it creates heat. This causes the paint to smell and odors such as a burning smell can be common for a couple of days.
This may be a damaged or frozen pulley on your smog pump, a/c compressor, power steering pump, etc. If your vehicle has a tensioner or idler pulley, that might also be malfunctioning. The smell is a belt burning due to resistance. Check that your belts are not glazed or cracked, and replace them first. While you have the belts removed, check all of the pulleys for side-to-side travel or locked conditions.
If the car is a manual and you are riding or slipping the clutch it could be that. Otherwise if you have been real hard on the brakes lately they can create quite a smell aswell.
when changing the oil sometimes oil can be spilled on the engine block. as your engine heats up it causes this smell. it is completely normal
