Infiniti Fx35 Engine Timing Chain Kit with Water Pumps

Infiniti Fx35 Engine timing chain kit with water pumps

Starting at low prices, AutoBuffy stocks multiple engine timing chain kits with water pump for the Infiniti Fx35 from brands including top OE-quality brands. This kit replaces the chain, guides, tensioners, and water pump in one job — components that keep your engine's camshaft and crankshaft synchronized and coolant circulating. When the chain stretches or the water pump leaks, you risk misfires, overheating, and catastrophic engine damage.

Signs your Infiniti Fx35 needs a new timing chain kit with water pump

  • Rattling or slapping noise from the front of the engine at startup, especially when cold, indicating a stretched or slack timing chain
  • Check Engine light with camshaft or crankshaft position sensor codes (P0016, P0017, P0341, or similar timing correlation faults)
  • Rough idle, misfires, or noticeable loss of power caused by valve timing being off due to chain stretch
  • Coolant loss with no visible external leak, or a small drip from the water pump weep hole at the front of the engine
  • Engine overheating or temperature gauge rising higher than normal, pointing to a failing water pump impeller
  • Metal shavings or fine debris visible in the engine oil during an oil change, a sign of internal chain or guide wear

Which timing chain kit with water pump should you buy for your Infiniti Fx35?

The most important decision is whether to buy an OE-equivalent kit that matches factory specifications or a performance-oriented kit with upgraded tensioners and guides. You also need to confirm whether your Infiniti Fx35 requires a single-run chain or a multi-row chain, and whether the water pump in the kit is metal-impeller or plastic-impeller, since metal impellers last significantly longer.

Replacing a timing chain kit with water pump on a Infiniti Fx35 requires draining coolant, removing the valve cover, front engine accessories, crankshaft harmonic balancer, and timing cover to access the chain and pump. Camshaft and crankshaft positions must be locked at top dead center before any components are disturbed, and all timing marks must be re-verified before the cover is reinstalled. Refill with fresh coolant and the correct engine oil, then check for leaks and confirm no fault codes before returning the vehicle to service.

Frequently asked questions

How much does it cost to replace timing chain kits with water pump on a Infiniti Fx35?
Parts for a Infiniti Fx35 timing chain kit with water pump start at low prices at AutoBuffy. Total cost including professional labor typically runs significantly higher, as this is a multi-hour job requiring engine front-end disassembly. Doing it yourself saves the largest share of that expense.
Can I replace just the water pump without doing the timing chain on a Infiniti Fx35?
Technically yes, but it is rarely advisable. On most Infiniti Fx35 engines the water pump is driven by or mounted behind the timing chain cover. Since the front end must be fully disassembled to reach the pump, replacing the chain, tensioners, and guides at the same time avoids repeating expensive labor when those components fail shortly after.
How long does a timing chain last on a Infiniti Fx35?
Timing chains are designed to last the life of the engine with proper oil maintenance, but real-world service life varies widely depending on oil change frequency and oil quality. Extended oil change intervals, low oil levels, or use of the wrong viscosity accelerate chain and tensioner wear significantly, leading to earlier replacement needs.
Is a stretched timing chain on a Infiniti Fx35 an emergency — can I keep driving?
A stretched timing chain should be treated as urgent, not a deferred repair. Continued driving risks the chain jumping a tooth, causing incorrect valve timing, or the chain snapping entirely. Either scenario can bend valves or cause piston-to-valve contact, converting a parts-and-labor repair into a full engine rebuild or replacement.
Does the timing chain kit with water pump for a Infiniti Fx35 include gaskets and seals?
It depends on the kit grade you choose. Basic kits include the chain, guides, tensioners, and water pump but may omit the water pump gasket or front cover seal. Master and complete kits bundle gaskets, o-rings, and seals. Always verify kit contents in the product listing before ordering to avoid a second parts run mid-job.
What happens if I install the timing chain one tooth off on a Infiniti Fx35?
Installing the chain one tooth off on a Infiniti Fx35 causes the camshaft and crankshaft to be out of phase, resulting in poor performance, misfires, hard starting, and potential valve-to-piston contact on interference engines. Always verify timing marks align precisely with manufacturer reference points before rotating the engine after reassembly.
