Its faults are reflected directly from the exhaust pipe, we must always look at it to detect any symptom, such as the smoke pot.

In some cases, the smoke is a bit compact, this happens when the engine heats up and disperses a strong smell, it can also show uncontrolled temperatures, which means that the liquid is burning refrigerant.

If the smoke is less dense, and does not clear easily, it could have an injection fault, it could also be due to radiator problems. Other options could also be the following:

Thermostat faults

In this case, there is a possibility that the thermostat may have been left open, resulting in excessive fuel consumption. Or else, if the thermostat is closed, the engine will get hot, which leads to the engine damage from overheating.

Lack of antifreeze (or water)


As there is a loss of anticoagulant in the winter time, the engine will stop heating up, and this will result in the freezing of its parts, which could stop the engine from starting.


If this happens, we cannot insist on starting the car because we will end up causing a fault in the circuits or there may simply be a break in the engine.

It is very important that constantly check this fluid in your engineespecially as the winter season approaches, so we would avoid these situations.
