A 2003 Nissan 350Z uses a timing chain, not a belt — the VQ35DE engine in this model is chain-driven throughout its production run.
Does a 2004 350Z have a timing belt or chain?
A 2004 350Z has a timing chain, identical to the 2003 model — both use the VQ35DE engine with a metal timing chain.
If you hear a rattle from the timing cover, it’s usually the plastic chain guides wearing out. Grab parts # Nissan 350Z Timing Chain Guide (13028-40U00) (guides) and # Nissan 350Z Timing Chain Tensioner (13070-40U00) (tensioner) along with the chain itself (# Nissan 350Z Timing Chain Kit (13070-40U01)) to avoid bigger headaches down the road. Stick with genuine Nissan parts or high-quality OEM equivalents like Aisin Timing Chain Kit for Nissan 350Z or Denso Timing Chain Kit for Nissan 350Z — they make a difference.
Does a Nissan 350z have a timing belt or chain?
Every Nissan 350Z uses a timing chain — this includes all model years (2003–2009) and trims (Base, Enthusiast, Touring, Track).
Chains don’t need replacement at set intervals like belts do, but keep an ear out for trouble. A rough idle, metallic rattling from the timing cover, or a check engine light with codes P0010–P0020 mean it’s time for an inspection. Nissan suggests checking the chain, guides, and tensioner every 60,000–100,000 miles, especially if you’ve got high miles or track time on the car.
How much is a timing chain for a 350Z?
A complete 350Z timing chain kit typically costs $350 to $550 for parts, with labor adding $750 to $1,100 depending on where you take it.
You’ll need the timing chain (# Nissan 350Z Timing Chain Kit (13070-40U01)), tensioner (# Nissan 350Z Timing Chain Tensioner (13070-40U00)), and two guide rails (# Nissan 350Z Timing Chain Guide (13028-40U00) and # 13028-43W00). OEM Nissan parts are the safest bet, but aftermarket kits from GReddy, HKS, or Tomei work too. Don’t forget to swap out the chain tensioner bolt and both camshaft/crankshaft seals while you’re in there — skipping this step usually leads to leaks later. If you're working on a different vehicle, you might also need to check the cost of other components like a thermostat.
Which Nissan models have timing chains?
Common Nissan models with timing chains include the Maxima (2004–2008), Altima (2004–2006), Pathfinder (2005–2007), Xterra (2005–2007), Frontier (2005–2007), and Quest (2004–2009).
Most VQ-series V6 engines (VQ35DE, VQ35HR) and some inline-4s like the QR25DE use chains. Always double-check your specific model year and engine code — either under the hood or via the VIN. Some models with QR25DE or MR20DE engines still run belts, so a quick service manual check never hurts. For example, a Honda Rincon 650 uses a belt-driven system, which is quite different from Nissan’s chain setup.
Do all Nissans have timing chains?
No — not all Nissans have timing chains. Many engines, especially older 4-cylinders (KA24DE, SR20DE), rely on timing belts.
Take the 2007–2012 Sentra with the QR25DE engine — it’s belt-driven. Even by 2026, some base models and older vehicles still use belts, though most modern Nissans (especially turbocharged ones) have switched to chains for durability. Always verify your engine code and model year before assuming. If you're curious about other vehicles, you might wonder, is a Nissan 350Z a reliable car?
Which engines have timing chains?
Timing chains are common in most modern inline-6, V6, and many inline-4 engines from manufacturers like BMW, Mercedes, GM, Honda, Mazda, and Nissan.
You’ll find them in BMW’s N52/N54/N55, Mercedes’ M276/M278, GM’s LS engines, Honda’s J35/J37, Mazda’s L-series and Skyactiv-G, and Nissan’s VQ-series. Chains handle high loads better than belts and don’t stretch as easily, which is why they’re standard in performance and turbo engines. Just remember — they need proper oil flow to last, so don’t skip those oil changes.
Do timing chains need to be replaced?
Timing chains rarely “need” replacement under normal conditions, but they should be inspected and often replaced between 80,000 and 150,000 miles.
Watch for rattling on startup, engine misfires (codes P0010–P0020), or metal debris in the oil. Unlike belts, chains don’t usually snap suddenly, but a stretched chain can skip teeth and trash your engine. Regular oil changes are non-negotiable — sludge buildup can kill the tensioner and speed up wear. If you're dealing with a different engine, you might need to check the horsepower specs for your vehicle.
Is it hard to change a timing chain?
Changing a timing chain is a moderately difficult job — it’s trickier than a belt, but patient DIYers can handle it with the right tools and prep.
You’ll need a torque wrench, timing light or scan tool, and about 6–8 hours. The engine must be at Top Dead Center (TDC) on #1 cylinder when you reassemble everything. Key steps: mark your camshaft and crankshaft sprockets, align timing marks, torque the tensioner to spec (usually 10–15 ft-lb), and set the tensioner plunger correctly. Seriously, watch a full teardown video for your exact engine before diving in. If you're working on a 350Z, you might also consider whether 350Z headers fit a G35 for potential performance upgrades.
How much does it cost to fix a timing chain?
The average cost to replace a timing chain tensioner or full chain kit is $800 to $1,200, including parts and labor.
Labor is the big expense here — it makes up 60–70% of the total. Dealerships charge the most ($1,200+), while independents average $800–$1,000. If you’re just swapping the tensioner, costs drop to $500–$800. Always get a written estimate and ask if they’re including gasket replacements (valve cover, timing cover) — shops often forget these, but they’re crucial for long-term reliability. For other vehicles, you might want to check the value of a 2003 Jeep Grand Cherokee if you're considering repairs.
Does Nissan Maxima have timing belt or chain?
Most 2004–2008 Nissan Maxima models have a timing chain, though some early 2004 VQ35DE models in certain markets may have come with belts.
Check under the hood for a timing cover with bolts instead of a removable belt cover. The VQ35DE in the 4th-gen Maxima (2004–2008) uses a chain. Still, verify your exact model year and trim — the 3.5 SE and 3.5 SL definitely came with the VQ35DE, but rare base models might differ by region.
Do Nissan cars have timing belts or chains?
Most modern Nissan cars use timing chains, especially V6 and turbocharged engines, but plenty of older 4-cylinder models still use belts.
For instance, the Sentra (2007–2012) with a QR25DE engine uses a belt, while the Altima (2007+) with the same engine switched to a chain. By 2026, Nissan leans heavily on chains for durability, but always confirm your engine code (MR20DE vs. MR20DD) with a service manual or VIN decoder to be sure. If you're comparing vehicles, you might ask, does a 350Z exhaust fit a G35?
Does my Audi have a timing belt or chain?
Most Audi 4-cylinder engines (e.g., 2.0 TFSI) use timing belts, while V6 and V8 engines (e.g., 3.0 TFSI, 4.2 FSI) use chains.
Case in point: the 2019 Audi A4 2.0 TFSI runs a timing belt, but the S4 and A6 with supercharged V6s use chains. Always look up your specific engine code (CJXB vs. CZSE) in the Audi service manual or VIN lookup. If your Audi has a chain, proper oil changes will keep it happy for the life of the engine.
Do timing chains last forever?
Timing chains do not last forever — they wear, stretch, or fail over time, especially if oil changes are neglected.
With regular oil changes (every 5,000–7,500 miles) and good synthetic oil, a timing chain can easily hit 150,000+ miles. Skip oil changes, and sludge buildup can kill the tensioner or accelerate wear. Listen for rattling on startup — it’s often the first warning sign. Chains rarely snap like belts, but a severely stretched chain can still cause major engine damage if you ignore it.
