Transmission Fluids, Coolants, & Other Fluids: What, When, and Why

When people think of car maintenance, they often focus on oil changes, tire rotations, or brake checks. But one of the most overlooked aspects of vehicle care is the proper maintenance of car fluids. From transmission fluid to coolant and other essential fluids, these elements are the lifeline of your car. Knowing what they are, when to change them, and why they matter can save you from costly repairs and keep your vehicle running smoothly on Dubai’s roads.

Why Car Fluids Are Important

Every fluid in your vehicle plays a vital role in performance, safety, and efficiency. They reduce friction, transfer power, cool down critical components, and prevent wear and tear. Ignoring fluid maintenance can lead to overheating, breakdowns, or even complete engine or transmission failure.

Transmission Fluid

What It Is

Transmission fluid lubricates the moving parts inside your transmission and helps transfer power from the engine to the wheels. It also cools down the system and prevents metal-to-metal friction.

When to Change It

  • Typically every 40,000–60,000 km or as recommended by your manufacturer
  • If you notice delayed gear shifts, slipping gears, or unusual noises, it may be time for a fluid change

Why It’s Important

  • Prevents overheating of the transmission
  • Ensures smooth and efficient gear shifts
  • Extends the life of your transmission system

Coolant (Antifreeze)

What It Is

Coolant regulates your engine’s temperature by absorbing heat and transferring it to the radiator. It also protects the engine from corrosion and scaling.

When to Change It

  • Usually every 2 years or 40,000 km
  • Check coolant levels regularly, especially in Dubai’s extreme heat

Why It’s Important

  • Prevents engine overheating
  • Protects the cooling system from rust and corrosion
  • Keeps the engine operating at the right temperature

Engine Oil

What It Is

Engine oil lubricates the engine’s internal components, reducing wear, and keeping everything running smoothly.

When to Change It

  • Every 5,000–10,000 km depending on the car type and oil grade
  • Luxury cars may require more frequent oil checks and changes

Why It’s Important

  • Prevents engine damage
  • Improves fuel efficiency
  • Extends engine life

Brake Fluid

What It Is

Brake fluid transfers the force from your foot on the brake pedal to the brakes themselves, allowing your car to stop safely.

When to Change It

  • Every 2 years or 30,000–40,000 km
  • Replace immediately if you notice spongy brakes or reduced braking power

Why It’s Important

  • Ensures responsive and safe braking
  • Prevents brake system failure

Power Steering Fluid

What It Is

This fluid makes steering easier by transmitting power to the steering system.

When to Change It

  • Every 50,000–100,000 km or if the steering feels stiff

Why It’s Important

  • Keeps steering smooth and responsive
  • Prevents wear on steering components

Windshield Washer Fluid

What It Is

A simple fluid that keeps your windshield clean and ensures clear visibility.

When to Change It

  • As needed; refill whenever it’s low

Why It’s Important

  • Provides safe driving visibility
  • Prevents streaks, dirt, and debris from blocking your view

Why Fluid Maintenance Is Crucial in Dubai

Dubai’s hot climate puts extra pressure on your car. Fluids evaporate faster, engines overheat more easily, and AC systems work harder. Regular checks and timely replacements of transmission fluids, coolants, and other essential fluids are vital for keeping your car in top condition.
