How to Maintain Your Volvo Excavator Engine for Maximum Life

— Or: How to Keep That Swedish Beast Roaring Like a Viking

You know that deep rumble your Volvo excavator makes when it fires up first thing in the morning? That sound isn’t just diesel combustion—it’s pure blue-collar poetry. But like any hard-working machine, your Volvo engine needs love. Not the flowers-and-candles kind. The kind that involves oil, filters, grit, and a healthy disrespect for “maintenance laziness.”

So if you want your Volvo engine to live a long, productive, tantrum-free life—read on. This is your no-nonsense, slightly smart-assed guide to engine longevity.

Because let’s face it—an excavator with a blown engine is just a very expensive sculpture.

Meet the Swedish Heart of Your Beast

Volvo engines (especially the D6, D7, D8, and D12 models) are damn good at what they do. Reliable. Efficient. Torquey as hell.

But no matter how bulletproof they seem, they’re not immortal. They will cough, splutter, and die early if you:

• Ignore service intervals

• Use cheap fluids

• Let filters clog like your uncle’s arteries

• Or run them like you're racing a Dakar Rally stage

Let’s not do that. Let’s give your engine the respect it deserves.

Step 1: Change the Oil (Yes, Like You’re Supposed To)

Let’s start with the most basic—and most ignored—rule in the game.

“I’ll do it next week” is the national anthem of engine destruction.

Volvo recommends oil changes around 250 to 500 hours, depending on engine type, usage, and operating conditions. If you’re working in a dust bowl, hauling rocks up a mountain, or letting your cousin who’s "sort of a mechanic" operate the thing… go on the shorter side.

Pro Tips:

• Use the right oil spec (Volvo VDS-4.5 or equivalent)

• Always replace the oil filter when you change oil (yes, always)

• Warm up the engine first—it drains better

Changing the oil late is like changing your underwear monthly. It may still function, but you’re risking long-term consequences.

Step 2: Air Filters – The Engine’s Nose Hairs

Your engine needs to breathe. It’s not optional.

Clogged air filters = choked airflow = high exhaust temps = cooked engines.

How to Keep It Clean:

• Inspect every 100 hours (more in dusty conditions)

• NEVER bang them on the ground to “clean” them—that’s how you kill them

• Replace them as soon as restriction indicators tell you to—or sooner if they look like they’ve been through a sandstorm

Also: don’t forget the inner filter. That’s the one that actually protects your engine when the outer one fails. Respect it.

Step 3: Fuel System – Clean Fuel = Happy Combustion

Bad fuel is like a dodgy kebab—everything seems fine until it’s not.

Water, dirt, and microbial growth in your diesel tank can destroy injectors faster than you can say “engine overhaul.”

Maintenance Checklist:

• Replace fuel filters every 500 hours, minimum

• Drain the water separator weekly (daily in humid climates)

• Use clean fuel from reliable sources (no, the back of someone's bakkie doesn’t count)

Bonus Tip: Add a diesel treatment occasionally to keep the injectors squeaky clean.

Step 4: Cooling System – Keep It Chill, Bru

Overheating is a one-way ticket to Engine Hell.

Check your coolant level every day. Check the radiator and cooler cores for debris every week. And clean the damn thing. Dust, mud, and leaves love to block airflow.

Key Reminders:

• Use Volvo-approved coolant, not the green stuff from your car

• Replace coolant every 2 years or 4,000 hours, whichever comes first

• Watch for leaks—hoses, clamps, or seals

Fun fact: Running without coolant is 100% effective at killing engines.

Step 5: Valve Adjustments – The Unsung Hero of Engine Longevity

Yeah, we know. “Valve lash” sounds like something from a romance novel. But it’s critical.

Incorrect valve clearance can lead to poor combustion, power loss, and eventually cracked valve seats or burnt valves.

When?

• Every 2,000 hours, or as specified in your engine manual

If you’re not comfortable with a feeler gauge and a torque wrench, get a qualified mechanic. This is precision work, not “wing it with a screwdriver” time.

Step 6: Turbocharger TLC – Spool It, Don’t Kill It

Your Volvo engine’s turbo isn’t just a fancy air pump—it’s the reason you’re not crawling around at 2km/h like an angry turtle.

Here’s how to treat it right:

• Let the engine idle for a few minutes before shutdown (to cool the turbo)

• Avoid revving the engine cold

• Check for oil leaks or whistling sounds (bad news)

And if your turbo fails? Don’t just bolt a new one on. Figure out why. It’s usually oil starvation, contaminated oil, or a blocked air filter upstream.

Step 7: Watch Your Gauges Like a Hawk with Trust Issues

Your instrument panel isn’t just decoration.

Pay attention to:

• Oil pressure

• Coolant temperature

• Fuel pressure

• Warning lights

If something spikes or drops suddenly—stop the machine. Shut it down. Investigate. Don’t keep working like a hero. That’s how engines become scrap.

Also, if your panel looks like a Christmas tree all the time? Time to stop ignoring your machine’s cry for help.

Step 8: Use Quality Parts (Yes, It Matters)

Listen, we get it. Genuine Volvo parts are pricey. But buying cheap filters and seals is like brushing your teeth with a chainsaw—spectacularly dumb.

At Vikfin, we stock:

• Quality used Volvo engines and components

• Tested, cleaned, ready-to-work parts

• OEM and high-quality aftermarket options

Bonus: We actually know what fits what (see our rants on compatibility).

Trust us: using a $3 oil filter to protect a $20,000 engine is what we call “dumb with confidence.”

Step 9: Don’t Let It Idle Forever

Here’s a weird one. Long idling kills engines too.

Why?

• Low combustion temps = carbon buildup

• Wet stacking (unburned fuel gumming up your exhaust)

• Wasted fuel and time

So if your machine’s just sitting there idling for 30 minutes every day while the crew sips tea? Cut it out. Run it or shut it.

Step 10: Daily Walkarounds (AKA Excavator Yoga)

Before you even start the engine:

• Check oil level

• Check coolant level

• Check for leaks (oil, fuel, coolant)

• Inspect belts and hoses

• Look for loose or missing bolts

It takes 5 minutes and can save you 5 days of downtime.

We know it’s boring. So is brushing your teeth. But you still do it (hopefully).

Bonus: Recognize the Early Signs of Engine Trouble

Catch these signs early and you’ll avoid a full-blown catastrophe:

• Hard starting (especially when warm)

• White or blue smoke

• Oil in the coolant (or vice versa—yikes)

• Loss of power

• Metal shavings in oil

Don’t ignore this stuff. Don’t “hope it goes away.” Get it checked. Fast.

Real-World Case Study: The Farmer Who Killed His D6

Let’s call him Pieter. Pieter had a Volvo EC210 with a D6 engine. Solid machine. Until he decided oil changes were “a waste of money.” He ran it 800 hours without changing the oil.

What happened?

• Turbo failed first.

• Then injectors started dripping.

• Then the engine spun a bearing.

• The machine now sits in a field, slowly returning to the earth.

Don’t be Pieter.
