The ZD30 is Nissan’s 3.0-litre four-cylinder diesel, fitted to the Patrol GU Y61 and the Navara D22. It runs a timing chain, not a belt. Here you will find the injectors, high pressure pumps, rebuild kits, gaskets and timing parts we list for it, with exhausts and intercoolers for both vehicles alongside.

Injectors or pump: test before you buy
Injectors and the high pressure pump are the two things ZD30 owners come to us for most. Hard starting, smoke, a rough idle and poor economy can come from either, and replacing the wrong one is an expensive way to find out.
If the engine has not been tested, injector testing is the cheaper first step, and we can talk you through what the results mean. Our ZD30 injector and pump article goes through the symptoms in more detail.
DI or common rail
The ZD30 came as the earlier direct-injection ZD30DI and the later common rail ZD30CR. The two use different pumps and injectors, and some engine parts suit one version only, so read the fitment line on each listing against your engine. Your engine number or build date settles which one you have. Send it through and we will check it for you.
ZD30 rebuild kits
Kits include pistons, rings, bearings and gaskets. Piston, main bearing and conrod bearing sizes are all selectable, from standard through to the machined sizes, so order to the figures your machine shop gives you rather than to guesswork. If the block has not been measured yet, you can still order and send the numbers later. Our guide to bearing and piston sizes explains what they mean.
While the engine is apart, look at the timing chain, tensioner and guides, the water pump and the rear main seal. We also do full engine rebuilds in our Oxley and Warana workshops.
ZD30 FAQs
Do the ZD30DI and the common rail ZD30 use the same injector pump?
No. The direct-injection engine and the common rail engine run different fuel systems, so the pump and the injectors are not interchangeable. Send us your engine number or build date and we will confirm which pump suits before you order.
Can I order a ZD30 rebuild kit before the block is measured?
Yes. Order the kit and send the machine shop's measurements when you have them. Pistons and bearings are packed to those sizes, so the kit does not leave us until the numbers are confirmed. A photo of the machinist's job docket is the quickest way to send them.
How much is a ZD30 common rail pump?
The high pressure pump for the Patrol ZD30 is $1,885.00. Test the injectors and pump before you replace either.
Is there a heavy duty clutch for the ZD30 Patrol?
The NPC extra heavy duty clutch and flywheel package is $1,782.00. It comes with a solid flywheel, a spigot and an aligning tool.
Which injector fits your engine?
Not sure which injector your ZD30 takes? Work it out at diesel injectors by vehicle.
