The different possible origins and risks of smell of burnt plastic on a Alfa Romeo Giulietta

So we begin our guideline with the different possible origins of burnt plastic smell on a Alfa Romeo Giulietta . Generally, noticing a plastic or rubber smell is hardly ever a good indicator. Indeed, modern cars are full of it and it could be the sign of a critical malfunction. Below we will talk about the different possible origins of burnt plastic smell:

  • Transmission oil: This is the main possible source of such an odor. Indeed, the action of gear or transmission oil is to lubricate the different elements of your gearbox so that all the gears and pinions are not damaged, it as well has a second action as a temperature regulator. Nevertheless, in the long run, the oil will lose its efficiency and will not lubricate the parts and control the temperature as well, which will bring about the oil to overheat and thus give off that burnt plastic smell on your Alfa Romeo Giulietta. You risk pre-wearing your gearbox if you don’t take care of it.
  • The accessory belt: Nevertheless rarer, it is possible with wear and tear that your belt, which is specifically done of rubber, will deteriorate and no longer rotate entirely on its axis. With the friction that this will bring about the plastic will heat up and burn out, this reaction will generate a strong smell of burnt plastic or rubber in the engine unit block of your Alfa Romeo Giulietta.
  • Defective hose wear: This circumstance occurs especially on Alfa Romeo Giulietta that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your car contrary to what you might think will bring about the plastic parts to wear out more fairly quickly. Hoses are the first to be affected by this phenomenon. The rubber will disintegrate little by little and with the rise in heat of the fluid that circulates in it, it might melt. The risk of this problem is the breakage of the accessory belt.
  • A body component: Less general, especially present on Alfa Romeo Giulietta’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body parts that might have been bent might rub against one of your wheels and give off that burnt plastic smell. This may as well pre-wear out your tyres.
