Learn the 4 essential car fluids you must check regularly to keep your vehicle running smoothly and safely. Simple tips every driver should know.
Introduction
Your car’s health isn’t just about engine power or shiny paint — it depends on the vital fluids running through it. Neglecting these fluids can lead to costly repairs, breakdowns, and even accidents. In this guide, we’ll go through the 4 fluids you must check to keep your car alive, ensuring your vehicle stays reliable and road-ready.
1. Engine Oil – The Car’s Lifeblood
Without engine oil, your engine parts will grind together and quickly fail. Always check the oil level and quality at least once a month. If the oil looks dark or smells burnt, it’s time for a change.
- Tip: Use the dipstick and ensure the oil level is between the minimum and maximum marks.
- Change Interval: Usually every 5,000–7,500 miles (8,000–12,000 km), but check your owner’s manual.
2. Coolant – The Temperature Regulator
Coolant prevents your engine from overheating in summer and freezing in winter. Low or dirty coolant can cause overheating and expensive damage.
- Tip: Check the coolant reservoir when the engine is cold. The fluid should be between the “MIN” and “MAX” lines.
- Change Interval: Every 30,000 miles (48,000 km) or as recommended by your manufacturer.
3. Brake Fluid – The Stop Saver
Brake fluid is crucial for your safety — without it, your brakes won’t work effectively. Over time, it can absorb moisture, reducing braking performance.
- Tip: Look for clear or light yellow fluid in the brake fluid reservoir. If it’s dark, flush and replace it.
- Change Interval: Every 2 years or 20,000 miles (32,000 km).
4. Transmission Fluid – The Gear Protector
Transmission fluid lubricates and cools the gearbox, ensuring smooth gear shifts. Low or dirty transmission fluid can cause gear slipping and transmission failure.
- Tip: Check the fluid while the engine is warm and running, using the transmission dipstick if available.
- Change Interval: Every 30,000–60,000 miles (48,000–96,000 km).
