Your car depends on several vital fluids to run efficiently and safely. Ignoring them can lead to overheating, brake failure, engine damage, or costly repairs — especially in Lagos traffic and weather conditions.
At Rudzz, we connect car owners in Surulere and beyond with verified mechanics who can inspect and service your vehicle professionally. But even before visiting a mechanic, here are 5 essential car fluids you should check every month.
1. Engine Oil 🛢️
Why it matters:
Engine oil lubricates moving parts, reduces friction, and prevents overheating. Low or dirty oil can seriously damage your engine.
What to check:
- Oil level (using the dipstick)
- Oil color (dark or gritty oil needs changing)
Warning signs:
- Engine knocking noise
- Oil warning light
- Burning smell
👉 Rudzz Tip: If you’re unsure which oil is right for your car, a verified Rudzz mechanic can inspect and recommend the correct oil for your engine type.
2. Coolant (Radiator Fluid) 🌡️
Why it matters:
Coolant prevents your engine from overheating — a very common problem in Nigerian traffic.
What to check:
- Coolant level in the reservoir
- Leaks under the car
- Correct coolant color (not rusty or muddy)
Warning signs:
- Engine temperature rising
- Steam from the bonnet
- Frequent overheating
👉 Rudzz Tip: Overheating can quickly ruin an engine. Book a coolant system check with a trusted mechanic on Rudzz before it becomes expensive.
3. Brake Fluid 🛑
Why it matters:
Brake fluid allows your brakes to work properly. Low or contaminated brake fluid can cause brake failure.
What to check:
- Fluid level in the brake reservoir
- Fluid color (should be clear or light yellow)
Warning signs:
- Spongy brake pedal
- Longer stopping distance
- Brake warning light
👉 Rudzz Tip: Brakes are not something to guess. Rudzz connects you with experienced brake specialists near you.
4. Power Steering Fluid 🔄
Why it matters:
This fluid makes steering smooth and easy. Low levels can make steering stiff or noisy.
What to check:
- Fluid level
- Leaks around the steering system
Warning signs:
- Hard steering
- Whining noise when turning
- Steering vibration
👉 Rudzz Tip: If steering feels difficult, don’t wait. A quick inspection by a Rudzz-listed mechanic can prevent bigger steering system damage.
5. Windshield Washer Fluid 🚘
Why it matters:
Clear visibility is critical, especially during rain, dust, or long drives.
What to check:
- Washer fluid level
- Proper spray from nozzles
Warning signs:
- Poor visibility
- No fluid spray on windshield
👉 Rudzz Tip: While simple, visibility-related issues can still affect safety. Rudzz service providers handle both minor and major car care needs.
