Small commercial vehicles work hard every day. Keeping them in good shape is important to avoid breakdowns and save money. Many problems can be found and fixed early if you know what to look for.
Trucks owners should follow these useful tips shared by the experts of one of the best Tata Motors authorised service centres in Delhi to spot and fix problems.

Check the Engine Light

The engine light is on the dashboard.
If it turns on, there may be a problem with the engine.
The issue could be small or big, so do not ignore it.
A loose fuel cap can sometimes cause the light to turn on.
Other causes include engine overheating or sensor issues.
If the light is blinking, stop driving and check immediately.
Use a scanner to find the problem or visit a mechanic.
Fixing small issues early can prevent bigger problems.

Listen for Strange Noises

Your vehicle should run smoothly without odd sounds.
Strange noises may mean a problem with the engine, brakes, or other parts.
A loud knocking sound could mean engine trouble.
A squeaking noise when braking might mean worn-out brake pads.
A hissing sound could mean an air or fluid leak.
Grinding noises may be a sign of transmission issues.
If you hear clicking, check the battery or axles.
Do not ignore unusual sounds; they can lead to bigger problems.
Visit a mechanic to find and fix the issue.

Monitor Fuel Efficiency

Your vehicle should give steady mileage per liter of fuel.
If fuel runs out faster than usual, there may be a problem.
A dirty air filter can make the engine use more fuel.
Low tire pressure can reduce fuel efficiency.
Faulty spark plugs can make the engine work harder.
Leaking fuel or clogged fuel injectors can waste fuel.
Driving too fast or carrying heavy loads can use more fuel.
Regular servicing helps maintain good fuel efficiency.
If mileage drops suddenly, get the vehicle checked.

Inspect the Tires

Tires should be in good condition for safe driving.
Check tire pressure regularly to avoid low or high pressure.
Low pressure can cause poor mileage and accidents.
High pressure can make tires burst.
Look for cracks, cuts, or bulges on tires.
Uneven tire wear may mean alignment or suspension problems.
Rotate tires every few months for even wear.
Worn-out tires lose grip and can slip on the road.

Test the Brakes

Brakes help stop the vehicle safely.
Press the brake pedal to check if it feels soft or hard.
Soft brakes may mean low brake fluid or air in the system.
Hard brakes can mean a problem with the brake pads or discs.
Listen for squeaking or grinding sounds when braking.
Squeaky brakes may mean worn-out brake pads.
Grinding noises can mean serious damage to the brake system.
If the vehicle pulls to one side when braking, get it checked.

Look for Fluid Leaks

Vehicles need different fluids to run smoothly.
Check under the vehicle for any wet spots or puddles.
Engine oil leaks can damage the engine.
Coolant leaks can cause the engine to overheat.
Brake fluid leaks can make brakes fail.
Transmission fluid leaks can affect gear shifting.
Power steering fluid leaks can make steering hard.
Fuel leaks are dangerous and can cause fires.

Check Battery Health

The battery helps start the vehicle.
A weak battery can make starting difficult.
Check for corrosion on battery terminals.
Clean dirty terminals to avoid connection issues.
Look for cracks or leaks in the battery.
Dim headlights may mean a weak battery.
If the engine cranks slowly, the battery may be low.
Replace old batteries before they fail.

Monitor Overheating

The engine should stay at a normal temperature while driving.
If the temperature gauge is too high, the engine is overheating.
Low coolant levels can cause overheating.
A broken radiator can make the engine too hot.
A faulty thermostat may not control temperature properly.
Leaking coolant can lead to overheating.
Turn off the engine if it gets too hot.
Let the engine cool before opening the hood.

Examine Lights and Signals

Lights and signals help you see and communicate while driving.
Check headlights, brake lights, and turn signals regularly.
Dim or flickering lights may mean a weak battery.
Broken lights make driving dangerous, especially at night.
Turn signals help other drivers know your direction.
If a light is not working, replace the bulb.
Clean dirty headlights for better visibility.
Check for loose or broken wiring in lights.

Pay Attention to Steering

Steering should feel smooth and easy to control.
If turning is hard, check power steering fluid.
Low fluid can make steering stiff.
Strange noises while turning may mean a problem.
Vibrations in the steering wheel can mean tire or alignment issues.
A pulling sensation to one side may mean poor wheel alignment.
Loose steering can be dangerous and needs checking.
Worn-out suspension parts can affect steering control.
