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

So we begin our guideline with the different possible origins of burnt plastic smell on a Alfa Romeo Giulia . In general, noticing a plastic or rubber smell is hardly ever a good signal. Obviously, modern cars are full of it and it could be the sign of a major breakdown. Down below we will review the different possible origins of burnt plastic smell:

  • Transmission oil: This is the main possible origin of such an odor. Obviously, the function 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 also has a second function as a temperature regulator. However, in the long run, the oil will lose its performance and will not lubricate the auto 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 Giulia. You risk pre-wearing your gearbox if you don’t take care of it.
  • The accessory belt: Although rarer, it is possible with wear and tear that your belt, which is principally done of rubber, will degrade 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 create a strong smell of burnt plastic or rubber in the engine unit block of your Alfa Romeo Giulia.
  • Defective hose wear: This case occurs specifically on Alfa Romeo Giulia that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your vehicle contrary to what you might think will bring about the plastic auto 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 may melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less basic, specifically present on Alfa Romeo Giulia’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body auto parts that may have been bent may rub against one of your wheels and give off that burnt plastic smell. This may also pre-wear out your tyres.
