The different possible sources and risks of smell of burnt plastic on a Fiat Doblo
So we commence our content page with the different possible sources of burnt plastic smell on a Fiat Doblo . Generally, noticing a plastic or rubber smell is never a good signal. Indeed, modern cars are full of it and it could be the sign of a important malfunction. Down below we will talk about the different possible origins of burnt plastic smell:
- Transmission oil: This is the most important possible origin of such an odor. Indeed, the action of gear or transmission oil is to lubricate the different components of your gearbox so that all the gears and pinions are not broken, it also has a second action as a temperature regulator. Nevertheless, with time, the oil will lose its effectiveness and will not lubricate the auto parts and control the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Fiat Doblo. 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 deteriorate and no longer rotate totally on its axis. With the friction that this will cause 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 Fiat Doblo.
- Defective hose wear: This circumstance occurs specifically on Fiat Doblo that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your vehicle contrary to what you might presume will cause the plastic auto parts to wear out more fairly quickly. Hoses are the first to be impacted 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 problem is the breakage of the accessory belt.
- A body component: Less common, specifically present on Fiat Doblo’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.
