SOURCE: what is the smell and does it have to be fixed?

A burning rubber smell under the hood might be just that - consider having your accessory drive belt inspected, as it is possible that a bearing in one of the accessories (alternator, power steering pump, air conditioning compressor, etc.) or in the tensioner mechanism might be failing. This sort of fault will often cause that particular accessory bearing to spin less freely than the others, and as a result the belt continues to pass over the associated pulley at the same speed as the engine. Essentially, the result is similar to a car spinning its tires on dry pavement - and a similar 'burning rubber' odor is the friction and heat of the rubberized belt.

If the odor is more like burning oil than burning rubber, the rear valve cover gasket is situated in a place that results in dripping oil, even small and unnoticable amounts, onto the exhaust manifold that is directly underneath the valve cover.

These two items might be places to start your inquiry. Best of luck to you!

SOURCE: when driving i can smell gas in my 2000 lexus es300

possibly your O rings which isolates fuel injectors from engine block are getting old and letting gasoline go out. it is very dangerous since it can cause fire. do not drive.

another cause is broken loose or cracked fuel lines. this is equally dangerous since it is under hood close to hot exhaust manifold.

if smell is from exhaust manifold, which means not the smeel of gasoline but exhaust fumes, this can be caused by broken exhaust manifold or a crack on it or problematic exhaust manifold gasket.

My tredmill works but after few mins I get burnt smell?


Treadmills are relatively simple machines, which means a burning smell can be quickly determined.

Check your treadmill belt for wear. Try to find where on the treadmill feels hot when you smell the burning. It could possibly be the electric motor or wiring giving out under load.

Fan with burn smell when engine switched off


It is normal for the fan to run for a short while (few minutes) after turning off the car to allow the heat in the radiator to dissipate. The time may be dependent on the coolant temperature or it could just be a fixed time (i.e. so many minutes). The burning smell could be a loose belt, but I suspect the radiator fan is electrical and not belt-driven. I think the burning smell could be oil from a leaking gasket. The oil drips onto the hot engine and voila... burnt oil. Not sure what you mean by new (new to you or 2013-14 model), but new cars should not have any leaking fluids. A stuck break caliper could aslo produce a burning smell.

Whenever I start the car it smokes than after warming up it stops smoking.


The key is how much smoke? Does the smoke have a smell to it. Are you consuming any fluids, like coolant, or oil?

Tons White smoke that is sweet smelling is usually coolant getting into the combustion chamber.

Less white smoke, especially if other cars are doing it, is normal. For every gallon of gas that you burn, you generate a gallon (GALLON) of water. so this water usually evaporates, but sometimes not. It has little or no smell.

If the smoke is bluish white, that is oil, but usually your converter would fill with oil, and cause error codes, or loss of power. This smell is distinct, but not necessarily sweet.... After the converter heats up, it may be able to burn off the oil and the smoke stops.

What are you consuming, fluid wise, will direct where you go next.
