When it gets cold in winter, load on car begins to increase, and this is followed by various breakdowns. For example, after starting engine, dashboard of car will pop out of engine fault light. But after riding for a while, anomaly disappeared, what happens?
Actually, an engine failure indicator is not necessarily a problem with engine itself, but can also be a "temporary failure" caused by changes in external environment. Especially in winter, when temperature is relatively low, when engine is just started, malfunction lamp pops up even before reaching operating temperature. So, if you start your car in winter and MIL is on, you can wait until engine's operating temperature is normal to see if MIL is on. If it does not go out, then problem is in the engine.
So, what do we do after confirming that engine is indeed defective? If it is determined that engine is indeed faulty, next thing we need to do is fix cause of engine fault. As a rule, when engine malfunction indicator light is on, problems arise in following places: firstly, this is engine air intake system. When there is a problem with intake system, engine lines can be blocked and check engine light will come on. The reason for this state of intake system is usually due to lack of regular cleaning of air filter.
Secondly, exhaust system. If there is a problem with exhaust system, check engine light will also come on. In addition, in case of problems with ignition system, engine malfunction lamp will also light up, and in serious cases, engine will even lie in place. Therefore, when you know cause of engine failure, you should send it to repair shop in time for repair. After talking about problem of car strobe lights in winter, editor will tell you about problem of frequent abnormal noises in winter cars.
When we drive in winter, we often find that our car noise gets louder and makes abnormal noises. What's happening? This is mainly due to following reasons. First, rubber parts of car chassis harden in winter, which causes them to make abnormal sounds when squeezed. The rubber parts of car chassis are rubber products, such as tires, and they harden in cold winter, so we must check them frequently and repair them in time if problems occur.
Secondly, when a car drives on a snowy road in winter, snow will be pulled into wheels, and some of gravel will inevitably be wrapped in snow. This gravel will fall into gap between wheel hub and brake disc, and make abnormal noise when vehicle is running. At this time, if we clear gravel in time, abnormal noise will disappear.
In addition, due to low temperature in winter, fluidity of oil deteriorates, and lubricating effect of various mechanical parts deteriorates when engine is running, so engine noise increases accordingly. Therefore, when operating a car in winter, it is necessary to choose an engine oil with low viscosity and good fluidity.
That's end of today's explanation of problems with winter cars. If you have any questions, please leave a message in comments area to ask questions.
