Common Mistakes On Old Cars

1. The car has a weak engine

Old cars with weak engines are relatively easy to recognize through the following signs:

  • The accelerator pedal travel is longer than when the car is normal.
  • The engine does not "run" exactly like the new car when you press the gas.

Want to determine the right Causes of engine power loss? Check the injectors, fuel lines and air filter. See details at 5 "Health" Warning Signals Automotive Engine.

2. Car shakes when accelerating

Some cars, if driven at a moderate speed, are still quiet and smooth, but when accelerating, they have problems such as shaking. This phenomenon comes from the vehicle not having enough fuel (running out of gas) during operation. More deeply, it is a sign of a clogged fuel filter or dirty injectors.

3. Poor elastic damping

This problem is often difficult to detect if you just go around on beautiful roads. To know if the elastic damping is poor, it is necessary to run through an area with potholes and rough roads. If the car is not smooth, the shock absorbers are constantly causing discomfort, it is better to check/replace the shock absorbers.

4. Old cars are hard to climb

Vehicle climbing is difficult due to many different reasons. The most common is a clogged car fuel filter. When operating, impurities of gasoline are retained on the filter, after a while, the fuel filter is clogged, causing the car to lack fuel. At this time, the car going uphill needs more fuel, leading to the old car's situation that is difficult to climb uphill - the engine is stalled.

5. Emit howling noise from vehicle bearings

Old car bearings often emit annoying howls when running at high speeds and reduce the vehicle's ability to operate. In addition to howling, cars can also vibrate – over time, the bearings will be broken. If you still try to move on, it is easy to cause an accident for the driver and passengers.

These problems stem from a variety of causes, which can include:

  • The temperature sensor and the refrigerant block are damaged.
  • Gas filter for a long time is clogged, excess - lack of gas.
  • Dirt clings to the outdoor unit or the air filter.
  • The belt that drives the engine block is slipping or slack.
  • ...

Things To Do After Buying A Used Car

Buying a used car often encounters a few problems as above. In order for the car to operate in the best way, you should perform the following tasks:

  • Oil change: take the car to a full new oil change from engine oil, brake fluid and gear oil. After that, it is necessary to maintain an oil change maintenance schedule to keep the car running smoothly and with less damage.
  • Check cooling water: clean the cooling tank and replace the damaged pipe (if any) so that the engine will not overheat when operating.
  • Check air conditioner, air filter and battery: with the battery, after 4 years of operation, you need to replace it. As for the air conditioner and air filter, these two parts often collect dust and affect the operation of the car. Therefore, it is recommended to bring to a professional to check and replace the air conditioner filter and engine air filter.
  • Check the tire, brake: brakes and tires directly affect the vehicle's safety system. Check your tires and brake pads for wear and see if they need to be replaced.
  • Wheel precision alignment: wheel camber after a period of operation may be misaligned. It is necessary to check and align the vehicle so that the vehicle does not wear tires, wobble, etc., causing unsafety.
  • Clean engine compartment, interior - exterior: "slapping" to the old car's appearance is essential. You can also consider replacing the part according to your preference.
