Van Servicing in the UK, A Comprehensive Guide to What Goes On

Engine Oil and Filter Change

This is the heart of an interim service as the engine oil lubricates the thousands of moving parts in your engine, reducing friction and preventing wear and tear.

As a result, over time, the oil becomes contaminated with dirt, tiny metal particles, and carbon deposits, so a fresh oil and filter change ensures your engine remains properly lubricated and clean.

Skipping this can lead to serious engine damage and a costly repair bill.

Lights

The mechanic will check all exterior lights, including headlights, sidelights, brake lights, indicators, and fog lights, to make sure they are all working correctly.

They will also check the condition of the light lenses for any cracks as well.

Tyre Checks

Tyres are your van's only contact with the road, so their condition is really paramount for your safety.

As a result, during an interim service, a professional technician will inspect all four tyres and the spare.

They will also check the tyre pressures and adjust them to the manufacturer's specification, and they will also check the tread depth, which must be at least 1.6mm by law, and look for any signs of damage like bulges, cuts, or cracks in the sidewall.

Visual Brake Check

The mechanic will also perform a visual inspection of the brakes to assess the condition of the pads and discs.

While they won't remove the wheels, they will be able to spot obvious signs of excessive wear and make you aware of it.

Top Up Fluids

Essential fluid levels will be checked and topped up, and this includes windscreen wash fluid and, if necessary, coolant and power steering fluid too.

As you can see, an interim van service is a quick but effective way to ensure your commercial vehicle stays in good condition between more comprehensive services.

Air Filter Change

Your engine needs a constant supply of clean air to function correctly.

Here, the air filter prevents dust, dirt, and other debris from entering the engine, so a clogged filter can reduce engine performance and fuel efficiency.

This is a standard replacement in a full service.

Fuel Filter Change

The fuel filter stops contaminants in the fuel from reaching the engine’s delicate fuel injection system.

As a result, a dirty fuel filter can restrict the flow of fuel, leading to a loss of power and poor performance.

In diesel engines, it’s particularly important as it also separates water from the fuel.

Brake Inspection

The wheels will also be removed to allow for a detailed inspection of the brake pads, discs, and callipers.

This then provides you with a more accurate assessment of their condition and identifies any potential issues that a visual check might miss.

Steering & Suspension

The steering and suspension components, including the shock absorbers, bushes, and linkages, will be checked for any signs of wear, damage, or leaks.

Here, a worn suspension can affect handling and comfort, while steering issues are a major safety concern.

Exhaust System

The entire exhaust system will also be checked for leaks, damage, and corrosion.

As a faulty exhaust can be noisy as well as allowing dangerous gases, like carbon monoxide, to leak into the cabin as well.

Battery

The battery and its terminals will also be inspected for signs of corrosion or damage, and a check will be performed to assess the battery’s overall health and charge too.

Here, a failing battery is one of the most common causes of vehicle breakdowns, causing you to lose revenue when it occurs.

Cooling System

The mechanic will check the entire cooling system, including the radiator, hoses, and coolant, for any signs of leaks or issues.

The coolant level will be checked and topped up if needed, and the concentration of the antifreeze will also be tested to ensure it provides you with adequate protection against freezing in winter as well.

As you can see, a full service is an excellent way to maintain your van, ensuring its continued reliability and helping to protect its value for you in the long run as well.

Brake Fluid Change

Brake fluid is hygroscopic, meaning it absorbs moisture over time.

This moisture then lowers the fluid's boiling point, which can affect the brakes' performance and even cause them to fail under heavy braking.

As a result, a brake fluid change is a key safety check here.

Spark Plugs

On petrol vans, spark plugs are needed for igniting the fuel-air mixture in the engine.

However, they degrade over time and can cause misfires and poor fuel economy, increasing your running costs as a result.

Consequently, you should replace them as part of a major service to ensure the engine runs smoothly and efficiently.

Pollen / Cabin Filter

This filter cleans the air that comes into the van's cabin, removing pollen, dust, and other allergens.

As a result, replacing it improves the air quality inside the van and ensures the heating and air conditioning system works properly.

Detailed Inspections

A major service often includes an even more in-depth inspection of components such as the cambelt (timing belt), gearbox, and differential.

Here, the mechanic will check for any unusual noises or leaks and will advise you on any major work that might be required in the future as well.

Consequently, this level of service is a significant investment, but it is the best way to ensure your van remains in its best condition and to identify any potential problems before they become serious and more costly to you to fix.

This is the most important reason, as a service ensures that safety-critical components, such as your brakes and steering, are in perfect working order.

As a professional will spot potential problems that you might not notice, helping to prevent an accident from occurring.

Breakdowns are a nightmare for any business, leading to lost time and income.

A service, therefore, helps to prevent unexpected failures by addressing small issues before they become major problems, as a well-maintained van is a dependable van.

Simple things like a clean air filter and correctly inflated tyres can have a big impact on your fuel consumption.

A serviced van will always tend to run more efficiently, saving you money on fuel as a result.

A full and up-to-date service history is a huge selling point when you come to sell your van, as it shows your prospective buyers that you have taken good care of the vehicle and gives them confidence that they are buying a reliable machine that won't cost them much to maintain moving forward.

Many manufacturer warranties also require you to service your van at a main dealer or an approved garage at specified intervals.

Failure to do so can invalidate your warranty, leaving you to pay for expensive repairs out of your own pocket.

Modern vans are full of sensors, and if a dashboard warning light comes on, our technicians will use a diagnostic OBD scanner to read the specific fault code, helping us pinpoint the exact problem.

As a result, an On-board Diagnostic (OBD) scanner at the garage can quickly read the fault code and pinpoint the problem in seconds for you.

You should also listen out for any strange sounds, as a squealing or grinding noise when you brake could mean your brake pads are worn down.

However, a rattling from underneath might indicate a problem with your exhaust system, protection plates, or suspension damage.

Therefore, unusual noises are often the first sign of a developing problem.

If your van is feeling sluggish, struggling to accelerate, or is using more fuel than usual, it could be a sign of a clogged filter or other issues affecting the engine.

As here, poor performance is your van’s way of telling you it needs a check-up to run efficiently.

Keep an eye out for puddles or drips under your van when it's parked.

A leak could be a sign of a problem with your engine oil, coolant, or brake fluid, and fluid leaks should always be looked into by a professional to prevent a serious issue as soon as possible.
