What to Do if Your Car Goes Through Water: Checking the Transmission Fluid and Other Essential Steps

Introduction

Driving through water can be a nerve-wracking experience, especially if the water is deep. While most modern cars are designed to handle a certain amount of water, it’s crucial to take the necessary precautions to ensure your car’s safety and prevent potential damage. One of the most important things to check after driving through water is your transmission fluid.

Checking the Transmission Fluid

Transmission fluid lubricates and cools the transmission system, allowing gears to shift smoothly. When your car goes through water, there’s a risk that water can enter the transmission through the breather vent or other openings. If water gets into the transmission, it can cause corrosion, reduce lubrication, and damage the transmission itself.

Here’s how to check your transmission fluid⁚

1. Park your car on a level surface.
2. Let the engine cool down completely.
3. Locate the transmission dipstick. It’s usually a yellow or orange dipstick with a handle that’s marked “Transmission” or “ATF.”
4. Pull out the dipstick and wipe it clean with a paper towel.
5. Reinsert the dipstick all the way and then pull it back out.
6. Check the fluid level. The fluid level should be between the “Full” and “Add” markings on the dipstick.
7. Inspect the fluid color and consistency. Transmission fluid should be a reddish-brown or pink color and have a smooth, slightly oily texture; If the fluid is milky, cloudy, or smells burnt, it may be contaminated with water and needs to be replaced.

Other Essential Steps

Besides checking the transmission fluid, here are other important steps to take after your car goes through water⁚

• Dry the car thoroughly. Use a towel or shop vac to remove any water that has accumulated in the car’s interior or under the hood. Pay special attention to electrical components and the engine.
• Check the engine air filter. If the water level was high, water may have entered the air intake system.
• Start the engine and listen for any unusual noises. If you hear any grinding or rattling sounds, it could indicate damage to the transmission or other engine components.
• Check the brakes. Water can get into the brake system and cause brake pads to become wet and ineffective.
• Take your car to a mechanic for a thorough inspection. Even if you don’t notice any immediate problems, it’s a good idea to have a mechanic check your car to ensure there’s no hidden damage.

Prevention Tips

To prevent water damage to your car, follow these tips⁚

• Avoid driving through deep water whenever possible. If you must drive through water, do so slowly and cautiously.
• Use a water wading guide. Check the water depth before driving through it.
• Check your car’s air intake location. If the air intake is low, it’s more likely to be affected by water.
• Consider installing a snorkel. A snorkel can help prevent water from entering the air intake.

Conclusion

Driving through water can be risky, but by taking the necessary precautions and checking your car thoroughly afterward, you can minimize the risk of damage. Remember to check your transmission fluid, dry the car thoroughly, and have your car inspected by a mechanic. With a little care and attention, you can keep your car running smoothly even after a watery adventure.
