Why airconditioning cleaning is essential before the summer holidays

The summer holidays are just around the corner. Many motorists and camper drivers therefore quickly check tire pressure, oil levels, and coolant. However, one important component is often overlooked: the air conditioning system.

Especially during long holiday drives, a properly functioning air conditioner is indispensable for comfort and a pleasant interior climate. But did you know that a dirty air conditioning system can not only cause unpleasant odors but also affect the air quality in the vehicle?

What happens inside an air conditioning system?

During the use of the air conditioning, condensation (moisture) forms inside the system. Combined with dust, pollen, and other contaminants, this creates an ideal environment for bacteria, molds, and yeasts. These microorganisms can accumulate in the ventilation and air conditioning system, causing the familiar musty smell that many drivers recognize as soon as the air conditioning is switched on.

In addition to unpleasant odors, contamination can also lead to reduced fresh airflow and a decrease in comfort while driving. This becomes noticeable quickly, especially during hot summer days. Want to learn more about this? Click here.

Why air conditioning cleaning is important before departure

A clean air conditioner contributes to:

  • Fresher air in the interior
  • Less chance of musty odors
  • A more pleasant driving experience during long journeys
  • Better air quality for the river and passengers
  • Improve efficiency in the air conditioning system

For vacationers who are on the road for a long time to their destination, this can make a significant difference in comfort.

More than just masking odors

Traditional air conditioning cleaners often focus on removing odors or disinfecting surfaces. However, this is only a temporary solution.

Tec4 Airco Cleaner takes a different approach. The formula combines environmentally friendly cleaning agents, enzumes, and probiotic bacteria. These probiotics not only help remove surface contamination but also target the biofilm that underlies many contamination problems in air conditioning systems.

When is an air conditioning cleaning necessary?

An air conditioning cleaning is certainly recommended when:

  • A musty or unpleasant odor comes from the ventilation
  • The vehicle has not been used intensively for a long time
  • The holiday season is approaching and the system will be used frequently again
  • It has been more than a year since the air conditioning system was cleaned

Tec4 recommends cleaning the air conditioning system at least once a year to maintain optimal air quality and system performance.

Ready for a fresh start to your holiday?

A holiday doesn’t start at the destination, but as soon as you step inside. By paying attention to the air conditioning system before departure, you ensure a comfortable journey and a more pleasant interior climate for all occupants.

A minor service can therefore make a big difference during your holiday journey.

Start the motorcycle season without contamination – prepare your motorcycle with Tec4 Moto Power

With a new motorcycle season approaching, many motorcyclists prepare their bikes for the road after winter storage. What’s often overlooked is that fuel can deteriorate during storage. This contamination builds up on key components in the engine – most notably fuel lines, fuel injectors, inlet and exhaust valves.

This contamination has a detrimental effect on engine efficiency resulting in lost performance, poor throttle response, increased emissions and reduced fuel economy.

Fuel degradation after winter storage

During extended periods of inactivity, the composition of gasoline changes. Oxidation and natural degradation can cause contamination to form and accumulate in the fuel system. This can lead to:

less smooth throttle response;

irregular idling;

increased fuel consumption.

This is a common problem, especially with motorcycles, which are often used seasonally.

The solution: Tec4 Moto Power

Tec4 Moto Power is a highly concentrated, technically advanced formulation designed to effectively remove this contamination.

Wet Belts – Maximize Performance with Proper Service

In modern engines, wet belts play a crucial role in keeping the engine running smoothly and efficiently. Despite their reliability, there are many misconceptions about their operation and lifespan. Tec4 clarifies the facts and explains how proper service – including the use of Tec4 Oil System Cleaner and Tec4 Long Life Oil System Cleaner – can significantly extend the life of the wet belt.

Facts and Myths about Wet Timing Belts

Facts:

  • All timing belts and multi-rib belts are vulcanized at 200˚C, making them resistant to extreme conditions.
  • Wet timing belts are specifically designed to operate in contact with engine oil.
  • They save approximately 1% on fuel consumption and generate less noise during operation.
  • Wet belts are compatible with various types of engine oil without affecting performance.

Myths:

  • Non-recommended oil does dissolve the belt.
  • Combustion soot does lubricate the belt
  • Wet belts cannot reach their specified lifespan.
  • Wet belts are weaker than dry belts; they are engineered for long-lasting performance in oil.

Factors that Reduce Wet Timing Belt Lifespan

The lifespan of a wet timing belt can be shortened by:

Oil acidification, caused by fuel contamination, especially Bio-ethanol E10 (approx. 10%). Higher pH values affect the belt.

Carbon deposits from combustion that enter the engine oil, damaging the belt coating.

Interactions between carbon and Bio-ethanol forming substances that accumulate in unwanted areas, such as piston ring and oil scraper ring grooves, leading to increased oil consumption.

Low oil levels, which cause extreme oil temperatures that accelerate belt wear.

Aged or contaminated engine oil.

The Importance of Flushing with Tec4 Oil System Cleaner

Before adding new oil, it is essential to thoroughly clean the oil system. Tec4 Oil System Cleaner removes old oil, carbon deposits, and other contaminants that could damage the belt. Flushing ensures that harmful residues do not affect the new oil or timing belt, significantly extending belt life.

Optimizing with Tec4 Long Life Oil System Cleaner

Adding Tec4 Long Life Oil System Cleaner to new oil prevents acidification, protects the timing belt and other critical components, and maintains the oil’s optimal properties for longer. Benefits include:

  • Preserving the belt coating and strength
  • Reducing carbon and Bio-ethanol deposits
  • Improving lubrication and cooling efficiency of the engine oil

Recommended Service for Wet Belts

To maximize the lifespan of the belt, Tec4 recommends:

Inspecting cylinder walls with a videoscope if needed.

Changing the engine oil at least once a year or every 15,000 km.

Flushing the oil system with Tec4 Oil System Cleaner before adding new oil.

Adding Tec4 Long Life Oil System Cleaner to the new oil.

Using high-quality oil and preferably E5 fuel (less Bio-ethanol).

Avoiding short trips under 10 km and taking regular longer trips (50 km+).

Checking the oil pickup strainer if oil pressure problems occur and replacing if necessary.

Wet belts are reliable and efficient, but proper maintenance is key.

Flushing the system with Tec4 Oil System Cleaner and adding Tec4 Long Life Oil System Cleaner to new oil minimizes the negative effects of carbon and Bio-ethanol, keeps the belt performing optimally, and significantly extends its lifespan.

Tec4 advises following these service steps to get the most out of your engine and protect your wet belt from premature wear.

New oil doesn’t automatically mean a clean start

Posted on by Lotte

In engine maintenance/servicing, an oil change is often seen as the solution for a variety of complaints: rough running, increased wear, or contamination. In practice, however, new engine oil often doesn’t have the desired effect.


The cause? Residual contamination in the lubrication system.

Without prior cleaning/flushing, a large amount of old oil, sludge, and deposits remain in the engine. New oil mixes with this immediately, largely negating the benefit of changing the oil.

What is left behind after a standard oil change?

When draining engine oil, only a portion of the contamination is removed. In practice, the following remains:

increased deposits of tar, varnish, carbon particles, and sludge in the lubrication system and piston grooves.

This contamination is often invisible, but it does directly affect lubrication and engine performance.

New oil mixes with old contamination

When new oil is added to a contaminated system:

  • it mixes immediately with the remaining old oil
  • it absorbs the left over contamination and sludge
  • it loses its lubrication and cleaning effects faster

The result is that the new oil becomes contaminated more quickly, degrades more quickly and cannot optimally perform its protective function.

Limited effect on wear and performance:

When contamination remains in the lubrication system, the following can occur:

  • reduced oil flow
  • higher internal friction
  • increased wear of moving parts
  • greater risk of system failures

An oil change without flushing does not address the cause, but only part of the symptom.

Cleaning before an oil change: the correct order

Professional oil system cleaning/flushing before changing the oil ensures that:

  • deposits and contamination is flushed and drained
  • oil channels are clear again
  • new oil can actually do its job

Only in a clean system can fresh engine oil provide optimum lubrication, cooling and protection.

Preventive service instead of reactive repairs

For workshops, this represents a significant shift:
don’t wait until problems arise, but offer preventive service.

Flushing before oil changes:

  • extends the life of engine components
  • reduces the risk of consequential damage/repairs
  • increases vehicle reliability

New engine oil is only effective in a clean engine.
Without prior cleaning, contamination and deposits remain, significantly limiting the benefits of an oil change.

For workshops that want to optimally serve their hybrid customers, a good fuel cleaner is a smart and cost-effective choice.

Cleaning the Lubrication System Before an Oil Change: Necessity or Unnecessary Luxury?

Posted on by Lotte

Cleaning the Lubrication System Before an Oil Change: Necessity or Unnecessary Luxury?

An oil change is one of the most commonly performed maintenance tasks in workshops. Yet it is often forgotten that new engine oil can only perform well in a clean lubrication system. Contaminated oil channels mean that even the best engine oil cannot perform optimally.

How contamination in the lubrication system develops

Even engine oil has its limits. During vehicle use, the following occurs:

  • Carbon deposits
  • Sludge formation
  • Aged oil residues

These contaminants accumulate in:

  • Oil channels
  • Hydraulic lifters
  • Turbo oil supply systems

This buildup happens especially with long service intervals, short trips, and start-stop systems.

Why new engine oil alone is not enough

With a standard oil change, almost always a residue of old oil remains in the system. Additionally, deposits are not removed and can mix with the new oil again. This can lead to:

  • Reduced lubrication
  • Uneven oil circulation
  • Increased wear

New oil in a contaminated system = suboptimal result.

Modern vehicles are more sensitive than ever

Modern engines:

  • Have tighter tolerances
  • Use thinner oils
  • Work with turbochargers and start-stop technologies

Because of this, even slight contamination can noticeably impact:

  • Engine operation
  • Noise
  • Lifespan of components

When is flushing the lubrication system a necessity?

According to the article, lubrication system cleaning before an oil change is recommended in the following situations:
✔ During every preventive maintenance service
✔ For vehicles with start-stop or hybrid drivetrains
✔ With long maintenance intervals
✔ When there are irregular engine running conditions or ticking noises

Flushing before an oil change is not a luxury, but modern maintenance.
