Latest update date: February 08, 05

The rainy season in Saigon usually lasts from April - May to September - October, some years it even ends later. According to statistics, the average annual rainfall in Ho Chi Minh City is about 4mm, concentrated mainly in the rainy season. The rains often come quickly and strongly, causing local flooding in many places, greatly affecting traffic and vehicles, especially cars.

AAA (American Automobile Association): AAA research shows that heavy rain significantly reduces driver visibility. In moderate rain, visibility can be reduced to 1/4 compared to sunny weather.

With the traffic situation in Saigon, cars stalling due to flooding is quite common and causes a lot of trouble. According to records from car garages, the number of cars having problems and breakdowns in the rainy season increases by 20-30% compared to other months of the year. The main reason is due to:

  • Rainwater and mud affect electronic details and components
  • Water seeping into the engine compartment causes engine stalling and hydrostatic shock
  • Slippery roads can easily cause collisions and accidents
  • Poor visibility makes maneuvering more difficult

Therefore, to ensure safety and good operation during the rainy season, car owners need to carefully prepare their "darling cars". Here are the important things to do!

How to Safely Care for Your Car in the Rainy Season

Check and maintain before the rainy season

Ensure good visibility

The most important factor when driving in the rain is ensuring visibility. The following details need to be checked and processed:

  • Windshield and rearview mirrors: Clean and replace if cracked or blurred. Check glass cleaning, add specialized cleaning fluid if necessary.
  • Wipers: Replace if worn, making sure to wipe away rainwater. Check out features like automatic wipers and speed adjustment.
  • Headlights, taillights: Clean and replace light bulbs if necessary. Adjust the lighting angle appropriately.

Check the electrical system

Heavy rain causes the vehicle's electrical equipment to operate continuously and consume more electricity. Attention should be paid:

  • Check the wires, fuses, and electrical connections for open or short circuits.
  • Check the battery, replace it if it is too old. Make sure the battery is always fully charged.
  • Avoid letting water get into the engine compartment and electrical control boxes.

Check tires and brakes

Tires and brakes are two important details directly related to safety. Noteworthy:

Tire

  • Check tire wear, replace if worn beyond limit (1.6mm).
  • Check tire pressure regularly, pump to the recommended pressure (usually 30-32psi).
  • Rotate tires periodically to wear evenly and prolong life.

Brake

  • Check brake pads and brake discs, replace if worn beyond the limit.
  • Check brake fluid, replace if necessary.
  • Check the handbrake, the ABS brake works well.

Waterproof, anti-rust

Rainwater and mud that stays on the car for a long time will cause rust and damage. Attention should be paid:

  • Apply a layer of adhesive to protect the vehicle's underbody, gaps, and joints.
  • Waterproof silicone spray for rubber parts such as door gaskets, dashboard, fender braces.
  • Check and clean the rainwater drainage system such as door drainage pipes and sunroofs.

  1. Turn off the engine immediately, remove the key.
  2. Do not try to start the engine again to avoid water entering the combustion chamber and causing hydrostatic shock.
  3. Contact rescue and tow the vehicle to a dry place for treatment.
