The Nissan D21 ute is a trusted workhorse you still see on Australian roads. 

Many of these vehicles have clocked up decades and hundreds of thousands of kilometres. Because of this, the components that keep your drivetrain stable begin to fail, which is why engine mounts are a common talking point in Adelaide and right across the country. 

Choosing the correct Nissan D21 engine mount is one of the most critical maintenance tasks you’ll face. Picking the wrong one and you’ll face issues like engine vibration, poor alignment, and a result that feels rougher than a roo in a rut. 

At Nisswreck, we know that confirming engine mount compatibility before you click “buy” is the only way to make sure your engine stays exactly where it belongs.

So, let’s get to the bottom of what you need to know before you spend your time or coin on new mounts for your Nissan D21.

Overview of the Nissan D21 Engine Variants (Australian Models)

The Australian Nissan D21 market is a mixed bag. Local D21s came with a range of petrol and diesel engines. Common petrol engines included the Z24 four-cylinder and KA24, while many diesel fans know about the TD27 robust diesel unit. Each type brings different engine mount compatibility quirks.

Transmission choice is also a big thing here. You’ll find both manual and automatic Nissan D21 utes, and the choice can affect which mount fits where. Add to that the 2WD and 4WD chassis options, and you have even more combinations, each with its own mounting position and bracket differences.

Don’t forget that the engine code stamped on the block gives away not just the engine type but the mounting bracket and bolt pattern as well. This is one reason why many shops and owners get tripped up after doing only quick visual checks without taking a closer look. Confirming these details saves you both money and hassle in the long run.

Nissan D21 Engine Mount Types Explained

Understanding mount design helps avoid mistakes, and your Nissan D21 engine mount setup typically includes:

Left-Hand vs Right-Hand Engine Mounts

The Nissan D21 engine mount set always comes as a left and a right. These mounts are not interchangeable. The brackets, rubber block shapes, and sometimes the bolt holes are slightly offset or have mirrored patterns. This is a consistent tripwire if you’re switching sides or looking at mounts off another Nissan model.

Rubber vs Hydraulic Mounts

Most Aussie-delivered Nissan D21 utes use a plain rubber engine mount, designed for toughness. However, some later or special order models may have hydraulic mounts, especially for diesel engines. Hydraulic mounts help limit vibration but are less common here. Rubber mounts might look the same, but have different hardness levels based on whether they’re made for petrol or diesel.

Aftermarket vs OEM-Style Mounts

Aftermarket Nissan D21 engine mount options exist, some made to suit heavy-duty or off-road setups. Genuine mounts tend to use slightly better rubber and match the factory hardness, though there are quality aftermarket parts out there. This is one reason that mounts that look the same can still give different performance.

If you’re a local D21 owner, always look for mounts matched to the correct engine and build year. The mounting brackets on Australian D21s, especially on locally-assembled utes, can be different from those on models imported for other markets.

Engine Mount Compatibility by Engine Type

Petrol Nissan D21 Models:

• The Z24 and KA24 petrol-powered D21s share some similarities in mount position, but mounts are not always identical. You can swap some between Z24-powered 2WD and 4WD models, but check part numbers before you grab a second-hand set from a mate’s shed.
• Automatic transmission D21s sometimes need a different mount due to clearance and bracket differences. Manual and auto mounts are not always a straight swap.

Diesel Nissan D21 Models:

• The TD27 diesel uses heavier engine mounts, designed to take extra weight and vibration. The brackets are shaped and reinforced differently.
• Do not try to fit a petrol mount to a diesel (or vice versa). The rubber hardness, bracket size, and even the bolts themselves are different.

2WD vs 4WD Differences:

• 4WD Nissan D21 utes can use different mount angles to clear front drive components. The chassis rails are shaped to fit the transfer case, affecting mount height and spread.
• 2WD utes have simpler crossmembers, and in some models, the mounts need a different bracket or bolt orientation.
• Don’t assume 2WD and 4WD mounts match, even if the engine type is the same.

Fits: 

• D21 Z24 2WD petrol (manual to manual, same year)
• D21 TD27 diesel mounts with matching diesel bracket (2WD and 4WD can differ by year)

Does Not Fit: 

• Petrol to diesel or diesel to petrol (mount hardness and bracket change)
• Manual to auto swaps without checking bracket shape
• 2WD mounts on 4WD D21s when the crossmember or bracket differs

Always check your D21 build year, engine code (Z24, KA24, TD27), and transmission type. Nisswreck’s database includes many variants for the D21, so call out the exact combo you have.

Common Fitment Mistakes to Avoid

Even experienced mechanics and enthusiasts still mix up their engine mount compatibility for the D21. As one of the leading Nissan wreckers in Adelaide, returns about wrong Nissan D21 engine mount fitment usually came down to these avoidable errors.

• Mixing up petrol and diesel mounts. While they’re visually similar, each offers a different hardness or bolt pattern.
• Picking by sight alone. An old mount may look just like the new one, but positions or bracket shapes can differ by year or engine code.
• Overlooking changes between build years. Nissan often tweaked mounts during a model run. So, always check your D21 build date.
• Replacing only one mount. If you do that, worn-out old mounts on the other side can stress the new one. Always consider changing mounts as a pair.

Signs Your Nissan D21 Engine Mount Needs Replacement

If you see your hardbody struggling on the road, you might be tempted to sell your Nissan for cash. But before you make that decision, look closely at the signs. In most cases, you’ll spot the need for a new Nissan D21 engine mount with these symptoms and use your D21 longer instead of selling it for cash. 

Look for: 

• Noticeable vibration through the cabin, especially at idle or while revving
• Thumping or clunking noise from the engine bay during acceleration or when shifting gears
• The engine budges more than a few centimetres when you blip the throttle under load
• Visible cracks or separation in the rubber, or if the mount sits lower on one side

Aftermarket vs Genuine Nissan D21 Engine Mounts

You have two choices: aftermarket or genuine Nissan D21 engine mounts. Genuine Nissan mounts can give you a longer lifespan, especially in standard use. Some high-quality aftermarket options do compete well, especially for drivers who need heavy-duty or high-load setups, which is common for D21s used for towing or out in the bush.

Look for mounts rated for the correct engine. For diesel, go for a heavy-duty spec if you tow. Quality comes down to the rubber mix, bracket welding, and whether it matches the original part number. In our experience, buying mounts from a reputable Australian supplier is the best way to dodge cheap copies that won’t last in local conditions.

• Confirm whether your D21 is 2WD or 4WD
• Check if your transmission is manual or automatic
• Match the build year stamped on your vehicle’s plate
• Verify the part number against your current or old mount
