Things to know when buying a used car

The tightness of the door, the underside of the engine block or the engine mounts are things to pay attention to when buying a used car that not many people know.

Experience in checking parts when buying a used car such as doors, engine block, cooling system, tires...

1. The door

Check if the doors close tightly, are there any gaps or warping? If so, the car has been in a collision, depending on the severity of the collision.

2. Engine block

Check the underside of the engine block for oil leaks. If there is, it is likely that the gasket is worn. If there is no oil leak, it is possible that many people have foreseen it, so they use thick oil of 20w-40 or 30w-50, which also helps prevent cars with exposed bearings from emitting black smoke. In fact, it is still best to use the type of oil required by the car.

3. Cooling system

Coolant hose leaking.

Check the cooling system such as the pipes are intact, many old cars often have leaks in these pipes. In mild cases, it can freeze by itself if the car uses concentrated coolant (must be mixed with water before use), otherwise it will cause a lack of water to heat the engine.

4. Tires

In addition to visual inspection, used car buyers should test drive. If the tires are worn, they will make a louder noise than usual. The noise is usually from the 2 rear wheels. If the car has 4-wheel drive, the 2 front wheels will wear more because of the active brakes first.

5. Air conditioner

Check if the air conditioner fan is running, if not the car will still be cold but a bit weak.

6. Tripod

There are 4 rubber engine mounts. If the engine mounts break, it will cause jerking when starting, and the replacement cost is very expensive.

Tripod

How to check: open the hood, put it in 1st gear and press the accelerator, if you see the engine jerking back or forward, replace it. It is also easy to see with the naked eye at the rubber feet. Most old cars have this phenomenon.

7. Brakes

Test the brakes for squealing noises. If so, the brake pads are worn or have sand in them. In this case, both the brake pads and the brake discs need to be replaced.

8. Clutch

How to tell if the clutch is worn with a manual transmission: release the brake completely, shift into 2nd gear, press the accelerator and slowly release the clutch. If you press the accelerator hard but the car does not move, it needs to be replaced. The second way is to turn off the engine, press the clutch, if you hear a noise, the clutch is worn.

In addition to the above parts, when buying a used car, you should not focus too much on whether the car is still "original", the engine has not been opened, because any used car needs to be repaired or replaced periodically. For example, a manual transmission car needs to replace the clutch every 100,000 km (depending on the load), replace the timing belt every 90,000 km. Automatic transmission cars need to replace the timing belt after about 90,000 -100,000 km, and the transmission oil and engine oil must be changed.
