Spark plugs are small components that play a massive role in your engine's performance. These little parts ignite the air-fuel mixture in your cylinders, powering every drive you take. Yet many South African drivers overlook them until problems arise. Here's everything you need to know about spark plug replacement and maintenance.

What Do Spark Plugs Actually Do?

Spark plugs create the electrical spark that ignites fuel in your engine's combustion chamber. Without properly functioning spark plugs, your engine struggles to start, runs rough, and wastes fuel. Most vehicles have one spark plug per cylinder — so a 4-cylinder car has four plugs, while a V6 has six.

5 Warning Signs Your Spark Plugs Need Replacing

1. Difficulty Starting Your Car

If your car cranks longer than usual before starting, worn spark plugs could be the culprit. Weak or fouled plugs struggle to create a strong enough spark, especially on cold Highveld mornings.

2. Rough Idling or Misfiring

Does your engine shake or vibrate when idling at a traffic light? This rough idle often indicates spark plug problems. Misfires — where the engine momentarily loses power — are another telltale sign.

3. Poor Fuel Efficiency

Noticed you're filling up more often? Worn spark plugs cause incomplete combustion, wasting fuel and hitting your wallet hard with current petrol prices.

4. Sluggish Acceleration

When you press the accelerator and your car hesitates or responds slowly, spark plugs may be to blame. Your engine needs strong, consistent sparks for proper power delivery.

5. Engine Warning Light

The check engine light can indicate many issues, but misfiring from bad spark plugs is a common trigger. Don't ignore this warning — have it checked before minor issues become major repairs.

When Should You Replace Spark Plugs?

Replacement intervals vary by plug type:

• Copper spark plugs: Every 30,000 to 50,000 km
• Platinum spark plugs: Every 60,000 to 100,000 km
• Iridium spark plugs: Every 100,000 to 150,000 km

Check your vehicle's service manual for specific recommendations. South African driving conditions — including dusty roads and stop-start traffic — can shorten these intervals.

Choosing the Right Spark Plugs for Your Vehicle

Match OEM Specifications

Always match your manufacturer's specifications for heat range, thread size, and electrode gap. Using the wrong plugs can cause engine damage or poor performance.

Copper vs Platinum vs Iridium

Copper plugs are affordable but wear faster. They're fine for older vehicles or those with frequent service schedules.

Platinum plugs last longer and maintain a consistent spark. They're the standard choice for most modern vehicles.

Iridium plugs offer the longest lifespan and best performance. Though pricier, they're cost-effective over time for high-mileage drivers.

Consider Your Driving Conditions

City drivers doing short trips may see more carbon buildup on plugs. Highway drivers typically get longer spark plug life. Choose accordingly.

Can You Replace Spark Plugs Yourself?

Spark plug replacement is straightforward on many vehicles, especially older models with easily accessible engines. You'll need:

• Spark plug socket and ratchet
• Gap gauge (if plugs aren't pre-gapped)
• Torque wrench for proper tightening
• Dielectric grease for the boots

However, some modern engines — particularly with transverse-mounted V6 configurations — have hard-to-reach plugs that require professional tools. If in doubt, have a mechanic handle it.

If you've ever wrestled with a heavy steering wheel or heard a strange whining noise when turning, your power steering pump might be on its way out. For South African drivers navigating tight parking spots and winding mountain passes, a failing power steering pump can turn every drive into a workout — and a safety risk.

Here's how to spot the warning signs before you're left stranded.

What Does the Power Steering Pump Do?

Your power steering pump pressurises hydraulic fluid, making it easy to turn the wheel with minimal effort. When it fails, steering becomes extremely difficult, especially at low speeds. Modern vehicles rely on this system — losing it isn't just inconvenient, it's dangerous.

1. Whining or Groaning Noise When Turning

This is the classic symptom. If you hear a high-pitched whine or groan when you turn the steering wheel — particularly at low speeds or when parking — your power steering pump is likely struggling. The noise often gets louder as the problem worsens.

Pro tip: The sound is usually loudest when the wheel is turned all the way to one side (full lock). Don't hold it there for more than a few seconds, as this puts extra strain on an already weakened pump.

2. Stiff or Heavy Steering

If your steering suddenly feels like you're driving a 1970s bakkie without power assist, the pump isn't generating enough pressure. This is especially noticeable at low speeds, when manoeuvring in traffic, or when parallel parking.

On South African roads, where unexpected potholes require quick steering corrections, heavy steering can be genuinely hazardous.

3. Slow Steering Response

A healthy power steering system responds instantly. If there's a delay between turning the wheel and the car actually changing direction, the pump may be failing to deliver consistent hydraulic pressure.

4. Power Steering Fluid Leaks

Check under your car for reddish or light brown fluid puddles near the front of the vehicle. Power steering fluid leaks often originate from:

• The pump itself
• High-pressure hoses
• The steering rack seals

Running a pump low on fluid accelerates wear and can cause permanent damage. If you spot a leak, top up the fluid and get it checked immediately.

5. Squealing on Startup

A brief squeal when you start the car — especially on cold Highveld mornings — can indicate a worn power steering pump belt or a pump that's working harder than it should. While a loose belt is an easy fix, a squealing pump often signals internal wear.

6. Discoloured or Foamy Power Steering Fluid

Pop the bonnet and check your power steering reservoir. Healthy fluid should be clear or light amber. If it's:

• Dark brown or black: Contaminated and overdue for a flush
• Foamy or bubbly: Air has entered the system, often due to a leak or failing pump

Contaminated fluid doesn't lubricate properly, causing the pump to overheat and wear out faster.

What Causes Power Steering Pump Failure?

Several factors contribute to pump wear:

• Low fluid levels: Running dry even briefly causes rapid damage
• Contaminated fluid: Old fluid loses its lubricating properties
• Holding full lock: Extended pressure spikes stress the pump
• High mileage: Like any hydraulic component, pumps wear over time

Can You Drive With a Failing Power Steering Pump?

Technically, yes — the car will still steer. But it'll require significant physical effort, especially at low speeds. More importantly, if the pump seizes completely, sudden loss of power assist while driving can catch you off guard.

Rather sort it out before it fails completely.

Keep Your Steering Smooth

Power steering is one of those things you don't appreciate until it's gone. If you're noticing any of these warning signs, don't ignore them. A R2,000 pump replacement now beats a R15,000 steering rack repair later.

Stay safe on SA roads — and keep that steering effortless.

South African roads are tough on your car's suspension. Between potholes, speed bumps, and gravel roads, your shocks, struts, and bushings take a beating daily. Ignoring suspension wear doesn't just make for an uncomfortable ride—it compromises your safety and can damage other expensive components.

Here's how to spot suspension problems before they become dangerous.

1. Excessive Bouncing After Speed Bumps

When your shocks and struts are healthy, your car should settle quickly after hitting a bump. If your vehicle keeps bouncing like a boat on waves, your dampers are worn out. Try this test: push down firmly on each corner of your parked car. It should bounce once and settle. More than one bounce? Time for new shocks.

2. Nose Diving When Braking

Does your car's front end dip dramatically when you brake? This "nose dive" indicates worn front struts. Beyond being uncomfortable, this increases your stopping distance—a serious safety concern on busy SA highways. Worn struts can add metres to your braking distance at high speeds.

3. Uneven Tyre Wear

Check your tyres regularly. If you notice cupping, scalloping, or wear on one edge, your suspension geometry is likely off. Worn bushings, ball joints, or tie rod ends cause the wheels to sit at incorrect angles, chewing through expensive tyres prematurely. Replacing a R500 bushing is cheaper than buying new tyres every few months.

4. Pulling or Drifting During Turns

Your car should hold its line through corners. If it feels like it's drifting, leaning excessively, or pulling to one side, your suspension components may be failing. This could be worn anti-roll bar links, tired springs, or damaged control arm bushings. Don't ignore this—it affects your ability to control the vehicle in emergencies.

5. Clunking or Knocking Noises

Hearing thuds, clunks, or knocking from underneath when driving over bumps? That's usually metal-on-metal contact where rubber bushings have deteriorated. Common culprits include:

• Control arm bushings
• Shock absorber mounts
• Anti-roll bar links
• Ball joints

These noises typically get worse over time and won't fix themselves. The longer you wait, the more damage spreads to connected components.

6. Visible Damage or Leaking Shocks

Pop your head under the car occasionally. Look for:

• Oil leaking from shock absorbers (they're gas or oil-filled)
• Cracked or perished rubber bushings
• Bent or damaged components from pothole impacts
• Corroded springs (common in coastal areas like Durban and Cape Town)

Why Suspension Maintenance Matters in SA

Our roads demand more from suspension systems than smooth European highways. A typical SA car needs suspension attention every 80,000 to 100,000 km—sometimes sooner if you regularly tackle gravel or pothole-riddled urban roads.

Delaying repairs leads to:

• Accelerated tyre wear
• Damaged wheel bearings
• Steering component failure
• Reduced braking effectiveness
• Poor handling in emergencies

Your car's timing belt is one of those parts you never see, but it's absolutely critical. This rubber belt keeps your engine's valves and pistons moving in perfect sync. When it fails, the results can be catastrophic – and expensive.

What Does a Timing Belt Do?

The timing belt connects your engine's crankshaft to the camshaft, ensuring the valves open and close at precisely the right moments. In interference engines (common in most modern cars), a broken timing belt means pistons can slam into open valves. The repair bill? Often R15,000 to R40,000 or more – sometimes it's cheaper to replace the entire engine.

When Should You Replace Your Timing Belt?

Most manufacturers recommend replacement between 60,000 km and 100,000 km, or every 4-6 years – whichever comes first. Here's a quick guide for popular South African vehicles:

• Toyota Corolla/Hilux (older models): 90,000 km
• VW Polo/Golf: 90,000-105,000 km
• Ford Ranger (2.2/3.2 TDCi): 150,000 km
• Hyundai i20/i10: 90,000 km
• Nissan NP200/NP300: 100,000 km

Note: Some newer vehicles use timing chains instead of belts, which typically last longer. Check your owner's manual or ask us if you're unsure.

5 Warning Signs Your Timing Belt Needs Attention

1. High-Pitched Squealing from the Engine

A worn or misaligned timing belt often produces a distinctive squealing or whining noise, especially on startup or acceleration.

2. Engine Misfires

If the timing belt has stretched or slipped, your engine's timing will be off. This causes rough idling, misfires, and poor performance.

3. Visible Cracks or Wear

If you can access your timing belt (or have a mechanic check), look for cracks, fraying, or shiny spots on the belt surface.

4. Oil Leaks Near the Timing Cover

Oil contamination can degrade the timing belt rubber faster. If you notice leaks near the front of the engine, get it checked immediately.

5. Engine Won't Start

If your timing belt has already snapped, the engine simply won't turn over. The starter motor will crank, but there's no combustion.

What's Included in a Timing Belt Kit?

A proper timing belt replacement should include:

• Timing belt – the main component
• Tensioner – keeps proper belt tension
• Idler pulleys – guide the belt
• Water pump – often replaced at the same time (it's driven by the timing belt)

At Ace Auto, we stock complete timing belt kits for all popular South African vehicles. Buying the kit is usually more cost-effective than replacing parts individually.

Don't Wait Until It Breaks

Unlike brake pads that squeal or tyres that wear visibly, a timing belt can fail without warning. The cost of preventative replacement (typically R2,500-R6,000 including labour) is a fraction of the engine damage a failure can cause.

A failing fuel pump can leave you stranded on the N1 or stuck in a shopping centre parking lot. Knowing the warning signs early can save you from an expensive tow truck call and get you to a parts shop before complete failure. Here's what every South African driver needs to watch for.

What Does Your Fuel Pump Actually Do?

Your fuel pump delivers petrol or diesel from the tank to your engine at the correct pressure. Modern vehicles use electric fuel pumps mounted inside the fuel tank, while older models may have mechanical pumps on the engine. When this critical component starts failing, your car will tell you—if you know what to listen for.

1. Engine Sputtering at High Speeds

If your engine runs smoothly at lower speeds but starts sputtering or jerking when you're cruising on the highway, your fuel pump may be struggling to deliver consistent fuel flow. This is often one of the earliest signs of fuel pump trouble.

2. Sudden Loss of Power Under Stress

Notice your car losing power when accelerating, climbing hills, or towing? A weak fuel pump can't keep up with increased fuel demands. If your car feels sluggish during these situations, have your fuel system checked.

3. Engine Won't Start (But Cranks Normally)

When you turn the key and the engine cranks but won't fire up, a dead fuel pump could be the culprit. Before the engine starts, you should hear a brief whining or humming sound from the fuel tank area—that's your pump priming. No sound? No fuel delivery.

4. Whining Noise From the Fuel Tank

A healthy fuel pump makes a low, quiet hum. A failing pump often produces a loud whining or droning noise that changes pitch with engine speed. This sound typically comes from the rear of the vehicle where the tank is located.

5. Decreased Fuel Efficiency

If you're filling up more often without changing your driving habits, a faulty fuel pump might be dumping too much fuel into the engine. This wastes petrol and money—especially painful with SA fuel prices.

6. Engine Surging

Does your car suddenly surge forward without pressing the accelerator harder? This can indicate inconsistent fuel delivery from a pump that's intermittently failing, causing irregular fuel pressure spikes.

7. Car Stalls in Hot Weather

South African summers are brutal on fuel pumps. If your car stalls when the temperature gauge climbs but starts again after cooling down, heat could be accelerating pump wear. The fuel in your tank actually helps cool the pump—running low on fuel in hot weather makes things worse.

How Long Does a Fuel Pump Last?

Most fuel pumps are designed to last 150,000 to 200,000 kilometres, but South African conditions—stop-start traffic, extreme heat, and fuel quality variations—can shorten that lifespan. Regular maintenance and keeping your tank at least quarter full helps extend pump life.

What to Do If You Suspect Fuel Pump Problems

Don't wait for complete failure. If you're experiencing any of these symptoms:

• Have a mechanic check your fuel pressure
• Listen for the pump priming when you turn the key
• Check for fuel pump-related error codes
• Source a quality replacement pump before you're stranded
