Complete Preventive Maintenance Checklist for Used Car Owners

Keep your pre-owned vehicle running like new with expert care

Buying a used car is a smart investment but keeping it reliable and efficient depends on how well it’s maintained. Preventive maintenance isn’t just about fixing issues; it’s about avoiding costly repairs, improving safety, and extending the life of your car.
At Signature cars, we help our customers stay confident on the road with regular maintenance support and expert inspections for every used vehicle we sell.

What Is Preventive Maintenance?

Preventive maintenance means checking, cleaning, and servicing your vehicle before problems occur.
Instead of waiting for a warning light or breakdown, you follow a routine that keeps all systems in good condition saving time, money, and worry.

When you buy a used car from our dealership, we make sure every vehicle is fully serviced and safety-inspected, so you start from a clean slate. But ongoing care is just as important.

Step-by-Step Preventive Maintenance Checklist

1. Check the Tires – Your Car’s Foundation

Tires are one of the most critical parts of your vehicle. Properly inflated and well-maintained tires improve fuel efficiency, safety, and comfort.

What to do:

• Use a tire pressure gauge — don’t rely on eyesight.
• Check the correct PSI on the door sticker or owner’s manual.
• Don’t forget the spare tire — it often requires higher pressure (up to 60 PSI).
• Inspect for nails, cuts, bulges, or uneven wear.
• Rotate tires every 8,000–10,000 km for even tread life.

Dealer tip: During our pre-delivery inspection, we check tire tread depth and replace any that don’t meet safety standards.

2. Engine Oil and Filters

Oil keeps your engine lubricated and cool. Dirty or low oil can damage the engine quickly.

How to check:

• Do it when the engine is cold, ideally in the morning.
• Pull out the dipstick, wipe, reinsert, and check the level and color.
• The oil type is printed on the oil cap (e.g., 5W-30 or 0W-20).

When to replace: Every 5,000–8,000 km or as advised by your dealer.

Also check:

• Oil filter – replace with every oil change.
• Air filter – inspect visually; replace if dusty or clogged.

3. Brake Fluid and Brake Pads

Your brakes are your vehicle’s most vital safety system.

What to look for:

• Fluid level should be between MIN and MAX marks on the reservoir.
• Low fluid often means brake pad wear, not a leak.
• Replace brake fluid every 2 years to maintain stopping power.
• Listen for squeaking or grinding noises — they indicate worn pads.

Dealer support: Every used car we sell undergoes a comprehensive brake system inspection before delivery.

4. Coolant (Engine Antifreeze)

Coolant prevents your engine from overheating and freezing.

How to check:

• Only inspect the overflow reservoir, not the radiator cap.
• The level should be between LOW and FULL marks.
• Check color — green, orange, or pink are normal; rusty or cloudy coolant means it’s time to replace.

Warning: Never open the radiator cap when the engine is hot.

Dealer tip: We check for coolant leaks, flush the system, and refill it to the correct level before you receive your car.

5. Transmission Fluid

Smooth gear shifting depends on clean, correctly-filled transmission fluid.

How to check (varies by car):

• Some cars require the engine running, others off but warm.
• Use the dipstick (if equipped) — fluid should be pinkish and clean.

Change interval: Every 40,000–60,000 km or as per manufacturer’s recommendation.

Dealer note: Many modern vehicles have sealed transmissions — we inspect these systems using specialized tools.

6. Battery and Electrical System

A weak battery can leave you stranded especially in UAE heat.

Check for:

• Corrosion on terminals (white or green residue).
• Tight connections on positive and negative cables.
• Replace the battery every 2–3 years, depending on usage.

Dealer care: We test each battery’s voltage and cranking amps before selling a used car, ensuring reliable starts.

7. Belts and Hoses

These parts keep your engine running smoothly by powering essential components like the alternator, AC, and power steering.

Look for:

• Cracks, frays, or glazing on belts.
• Bulges or soft spots on hoses.
• Replace any worn parts immediately to avoid sudden breakdowns.

Dealer advantage: Our technicians inspect all belts and hoses during every service visit.

8. Wiper Blades and Lights

Good visibility = safe driving.

Check:

• Wiper blades for cracks or streaks. Replace every 6 months.
• Headlights, indicators, brake lights, and reverse lights.

Dealer service: Before handing over any vehicle, we test and replace faulty bulbs or wipers.

9. Watch for Leaks

Fluid leaks are warning signs that something isn’t right.

How to test:

• Park overnight on clean cardboard.
• Check for oil, coolant, or transmission fluid stains.

Dealer promise: Every vehicle is inspected for leaks and repaired before listing.

10. Stay Alert for Sounds, Smells, and Feel

Your car communicates with you.

Pay attention to:

• Unusual noises – rattles, knocking, or grinding.
• Pulling to one side – may indicate brake or alignment issues.
• Unfamiliar smells – burning or fuel odor could signal leaks.

Early detection saves you from expensive repairs later.

11. Refer to Your Owner’s Manual

Every car is different. The owner’s manual lists:

• Correct oil and fluid types
• Service intervals
• Proper tire pressures
• Transmission and coolant check methods

If you bought your used car from us, we’ll explain these details during delivery and guide you on the best service schedule.
