How Do I Tell If My 79 Is VDJ79 V8 or GDJ79 Before I Buy a Snorkel?

If you've landed here, chances are you're about to invest in a snorkel for your Toyota 79 Series LandCruiser — great choice for dust management, water ingress prevention, and improving overall safety around the rig. But before you splash your hard-earned cash on a snorkel, especially when prices start from around $526, you need to know exactly what you’re working with. The key question: Is your 79 Series a VDJ79 V8 or a GDJ79? Buying the incorrect snorkel kit because you didn’t nail the engine code or fitment specifics can lead to a world of hassle—and that’s not including the “shed-on-a-Saturday” fitting mistakes I always warn about.
Why Does Engine Code Fitment Matter for Your Snorkel?
Toyota 79 Series LandCruisers come in different flavours, with key distinctions between the VDJ79 V8 models and their GDJ79 counterparts. Those variations don't just influence performance and specs; they determine how and where parts like snorkels fit onto the rig.

When hunting for snorkels, brands such as Safari offer a range of kits tailored specifically for either setup. Even top-tier manufacturers like ARMAX, who carry the Safari range, stress correct fitment by year and engine to avoid fitment nightmares or compromised function.
What Happens If You Fit the Wrong Snorkel? Poor sealing can lead to water ingress during creek crossings, risking expensive engine damage. Incorrect positioning might disrupt engine breathing, defeating the snorkel's purpose in dust-heavy environments. Potential clashes with towing setups or aftermarket accessories, compromising safety and utility.
So, how do you tell if your 79 is VDJ79 or GDJ79?
Step 1: Identify Your Engine Code (VDJ79 vs GDJ79 Identification)
Your first task is knowing exactly which motor you're dealing with. Here’s how to check:
Check the VIN & Registration Papers: The easiest way is often your vehicle registration papers or logbook, where the engine code is sometimes listed, especially if sourced from Toyota dealerships or official websites. Look Under the Bonnet: Raise the bonnet, locate the engine block itself, and look for an engraved or stamped code—typically on the front or side of the block. The VDJ79 V8 will usually have clear markings indicating “VDJ79.” The GDJ79, featuring a turbo diesel, will have “GDJ79” or something close. Consult Your Owner’s Manual: Toyota manuals often specify your engine variant and associated fitment notes. Ask Toyota Directly: A phone call or visit to your nearest Toyota dealership can quickly confirm your engine type if you provide your VIN. Distinctions Between VDJ79 and GDJ79 Engine Code Engine Type Key Specs Typical Model Years VDJ79 4.5L V8 Turbo Diesel 310hp, 650Nm torque 2015 onwards GDJ79 4.5L V6 Turbo Diesel 200hp, 450Nm torque 2014 onwards (pre-2023 facelift models)
Keep in mind the 2023 model changeover may affect snorkel fit. Always cross-verify with the exact model year.
Step 2: Confirm Year and Model Because Fitment Varies
Does your 79 Series pre-date the 2023 facelift? If you do a high-level search for snorkels without accounting for year-specific differences, you might unknowingly buy a kit that won’t fit. Always remember the mantra: “Always ask ‘what year and what engine?’ before talking parts.”

Safari snorkel kits are renowned for quality but crucially, their off-the-shelf models differ between the pre and post-2023 79s as Toyota updated airbox and cowl designs slightly.
Pre-2023 GDJ79 models: Typically require snorkels designed for the older cowl shape and air intake position. Post-2023 VDJ79 V8 models: New engine bay trims and snorkel positions mean alternative mounting brackets or taping is necessary.
Some brands like ARMAX include “Safari range” snorkels that offer tailored fitment guides; however, always double-check part numbers and reviews specific to your model year.
Step 3: Understand Why Snorkels Are Essential Beyond Just Dusty Trails Dust Management and Engine Breathing
Out here in Regional NSW, dust storms and dirt tracks are the bread and butter of off-roading, and snorkels are your first line of defence, ensuring your engine breathes clean air. A well-fitted snorkel sources air from a higher, cleaner point to minimise dirt ingestion and premature filter clogging.
Water Ingress Prevention and Risk Reduction
Whether you’re fording creeks or caught in sudden downpours, a correctly fitted snorkel prevents water entering the air intake. Water ingestion can lead to hydrolocking—a catastrophic engine failure that’s just not worth gambling on.
Towing Safety and Blind Spot Reduction
Many overlook that a snorkel can also aid towing setups by maintaining clean air to your engine while towing heavy loads in dusty or flooded terrain. And because these snorkels typically run high and fit snugly to the side of the cab, they minimise blind spots better than some https://dlf-ne.org/safari-armax-vs-v-spec-snorkel-what-is-the-difference-in-real-life/ https://dlf-ne.org/safari-armax-vs-v-spec-snorkel-what-is-the-difference-in-real-life/ aftermarket air intakes that stick out unpredictably.
Step 4: Buy From Trusted Brands and Dealers to Avoid "Shed-on-a-Saturday" Mistakes
With prices starting around $526, a snorkel is an investment that pays off, but you’re only as good as your gear and installation. From my experience, off-brand or generic snorkels that don’t account for specific engine codes or year variants often require cutting looms or fiddly rewiring—a job I hate seeing botched. Sloppy installations turn project days into “shed-on-a-Saturday” grief sessions.

Brands like Safari offer proven, factory-backed designs that match perfectly with Toyota's specs, reducing fitment headaches and allowing clean bolt-on installs. Dealers carrying the ARMAX Safari range tend to provide detailed fit guides and customer support tailored to your exact model and engine.
Summary Checklist Before You Buy a Snorkel for Your 79 Series Identify your engine code: VDJ79 V8 or GDJ79 V6 turbo diesel. Confirm your exact model year: Pre or post-2023 facelift. Look for snorkel kits listing explicit fitment for your engine code and year. Choose reputable brands like Safari or ARMAX Safari range to ensure quality fitment. Prepare for clean installation: no cut looms or messy wiring! Check pricing starting from around $526 and budget accordingly. Final Thoughts
Buying a snorkel isn’t just about how it looks on the side of your LandCruiser. It’s about protecting your engine’s breathing, minimising water ingress risk, and keeping your rig tough and safe whether you’re towing, crossing creeks, or powering through dusty outback tracks.

Take the time to identify your 79 Series’ engine code (VDJ79 vs GDJ79) and model year before throwing down cash on parts. Don’t fall for marketing fluff or generic advice that ignores these critical nuances. Brands like Safari and ARMAX understand this and deliver snorkels built to match your rig’s unique specs.

Remember: no half-arsed fitments—if it isn’t right, it’s not worth it. Ask “what year and what engine?” every time, and your snorkel will fit like it's supposed to, protecting your 79 for many years to come.
