Winter brings many troubles for car drivers as slippery runways, thick snow that obscures visibility, engine stall in the middle of the road for unknown reasons …
Winter can cause many types of car engine problems. In particular, in extreme cold weather areas, the problem related to the car’s engine will increase as failure to start the engine, engine noise, no sounding horn, or difficulty to start the engine.
In particular, one of the questions that many people often ask in the forums is the explanation of unknown causes of noise. I believe you must have also encountered at least once related to this problem in the winter.
Among them are many questions about why Toyota Corolla engines make noise when cold? And whether only Toyota engines cause noise in the winter or other engines of other brands also have the same situation.
Some Causes Of Toyota Corolla Engine Noise When Cold
You should know that in winter, the Toyota corolla’s engine may produce some normal noise due to natural friction in cold weather.
Therefore, you should carefully consider these types of noises to diagnose problems with your car instead of taking them to the garage right away.
Many countries have thick snow and ice. Ice hitting wheels, tires, and brake discs also make a strange noise. Look under your hood and remove the tape carefully, especially around wheels and brakes.
1. Loud And Dry Clunk
You may not drive your car often in the winter or leave it overnight, the oil in the engine will settle to the bottom of the system.
When starting up, the oil pump does not pump up the parts in the engine, so the machine does not lubricate.
After 3-5 minutes, the engine boom becomes smaller, it is a normal phenomenon.
However, if the case is that the sound persists continuously, even when the engine is hot and the noise is no longer as dry as when it was first started, accompanied by the engine releasing blue or black smoke.
That is the signal for the car’s piston and ring to be worn out, causing a collision with the cylinder wall. The lack of oil that is not detected in time will cause the engine to be unlubricated and make a loud noise.
2. The Hissing Sound Is Even And Fast
This is a very recognizable sound, because of the characteristic sound of rubber rubbing against metal surfaces. If the squeal appears as soon as the engine is cold, but disappears after a few minutes, the cause is because the belt has become damaged or has begun to show signs of hardening, and it is time to replace it.
Therefore, you should check the belt periodically to detect abnormalities such as tearing, cracking, damage caused by animals or weather.
If the squeal persists even when the engine is hot, it’s time to change the belt. Due to the dependence on weather conditions such as cold weather and the working environment, many manufacturers only recommend that vehicle users regularly check the belt during each routine maintenance to detect problems.
After each long parking in the winter or before long trips, car owners should visually check this sensitive detail because there have been many cases of belts being bitten by rats, scratched by something, or extreme weather.
3. The Dry Sound Grows Louder
This process takes place slowly over a long time, so many car owners only realize the situation clearly when it is too late. In particular, when it is cold, problems related to engine oil also occur more often.
It is a condition where the engine is not sufficiently lubricated, causing metal parts inside the engine to rub against each other, causing a dry sound.
Lubricating oil left too long without changing will burn and deposit, damaging the engine. The cause may be due to poor quality oil change or not changing the oil for a long time, to build up deposits, clog the oil line, the oil pump cannot pump enough oil pressure to the engine.
The louder the noise, the worse the engine’s internal lubrication, the higher the chance of getting stuck. As a result, a series of rapidly damaged parts such as pistons, cylinders, crankshafts, camshafts, etc.
4. Cluck Sound Of Toyota Corolla When Cold
The gearbox is a part that is fixed on the chassis, along with the engine, through rubber feet or hydraulic feet to create smoothness.
Meanwhile, the wheel is an oscillating part during the car’s movement on bumpy roads.
To transmit force from a stationary part to an oscillating part, Toyota car manufacturers have designed a part located on the semi-axle, which is a ball joint inside a bell, can effectively receive rotational force and change the length according to the amplitude of oscillation between the wheel and the chassis.
After long periods of driving in rough terrain and weather, or being exposed to water due to winter freezing and dirt, both the ball and the ball bearing can wear out and create gaps between them.
When cornering, the looseness will cause the ball to hit the wall of the basket, causing a rattle. In this case, a brand new replacement is the best choice instead of repair.
5. Creaking Sound In The Car Brake
On a winter morning, when the weather temperature is still low, and the car has been left overnight when starting, you can hear the screeching of the brakes.
If about 5-10 minutes and several times of pressing the brake, the sound disappears, then it is a normal phenomenon. Because of the rain or snow-covered, brake pads and discs have not yet dried.
Wet brakes, while the driver pulls the brake to stop when parking for many hours, can also cause an instant brake lock. To release the brake, put forward gear, slow throttle, and reverse gear again after a few times.
On many popular models like the Toyota Corolla, when the brake pads are worn to the limit, the steel foil will rub against the disc to signal to the driver and replace it.
But if the squeaking sound occurs continuously for a long time, it is an abnormal sign that the cause may be different, and the car needs to check factors like the brake pads, the wear of the brake pads, the brake disc is reversed, etc.
To overcome this phenomenon, take the car to the garage with measuring equipment, where the car will be determined the condition of the relevant details and handled promptly.
Conclusion
You may be more likely to experience Toyota Corolla engine problems in the winter than in the summer. Therefore, you should pay attention to some unusual noises to correct them in time.
The extremes of winter that cause a lot of freezing everything also seriously affect the starting of the engine so the Toyota Corolla engine can make a lot of noise when it’s cold.
