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.
If you have been (revving the car/racing/accident/excessive speeding) you will smell something similar to burning oil from the engine, also if it has been more than 10,000kms (6000 mile) since last oil change you should get it serviced.
I would go back to the oil change place. Fluid levels are their responsibility and you should have a trail of fluid from the leak. If you had no problems before the oil change and immediately after you have problems, then they are the people to talk to.
There are some basic systems that are to be checked when doing an oil change. Power steering fluid, washer fluid, and auto trans fluid are normal items the shops keep on hand to put in cars.
Now cars with rear differentials and standard transmissions are checked on request. Your problem is something that should normally be checked by a shop doing an oil change.
Some of the better shops grease the fittings, check the belts, spray the battery connections and check the Antifreeze.
If the Power steering was out of fluid, the pump may be damaged. There are also different fluids to use for each car company.
Jennifer what type of timing belt does your engine use ?
Is it Nylon ? When was the last time you had it changed ?
Burning plastic smell may be being caused by the timing belt bearing runners seizing and the belt is getting hot .
If the belt is due to snap you could cause a lot of damage to the engine if it breaks.
Might be worth getting a mechanics advice on this as a possible cause
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.
well this could be many things so first things first check your tires for any sign of something rubbing on them like at the sidewalls of the tires, than i would take a look at the brakes to make sure one of your pads or shoes didnt let loos from the plate, next i would move the the engine compartment, chck all the fluids not just oil and antifreeze... brake fluid powersteering fluid, also look at your serpentine belt also, take not of the where patterns on the pulleys, then if that all checks out on then run the car for a bit with the hood open and try to narrow down the place that the smelll is the strongest... that is what i would do if in my shop to start.
You could try looking at the idler pulleys or the air conditioner these 2 things can cause a noise like that, If you have to take the fan belt off make sure you draw a diagram so you know which way it goes, Sometimes you need to do this so you can spin the pulleys by hand to determin if it is one of them.
you either have the wrong type of fluid in it or the pump is going out. to change pump take the right side\passenger side tire off and remove the plastic cover and get to work (youll need a pully puller to get the pully off the pump fyi)
