Nakuuly Timing Belt Kit with Water Pump for Toyota 3.4L 5VZFE (1995–2004) — Complete kit with tensioners & thermostat

This Nakuuly timing belt kit with water pump is a complete replacement package engineered to restore timing system function and coolant circulation on Toyota 3.4L 5VZFE engines (1995–2004).

Designed for Toyota 4Runner, Tacoma, Tundra and T100 models powered by the 3.4L V6 (5VZFE), this all-in-one kit gathers the wear-prone components you typically replace during a timing service. It includes the timing belt plus tensioners, rollers, seals, thermostat and a new water pump, so you can perform a thorough preventative service and reduce the need for follow-up repairs. The kit replaces common OEM and aftermarket reference numbers such as TKT025, TBK965AWP, and WP2034.

What parts come in the kit and why are they bundled together?

The kit groups components that experience similar wear or are difficult to access separately once the timing cover is removed. Replacing everything at once reduces labor cost and the chance of secondary failures after the job.

• Timing belt — primary synchronization component between crankshaft and camshafts
• Hydraulic tensioner, idler and tensioner rollers — maintain proper belt tension and alignment
• Water pump and gasket — restores coolant flow and prevents leaks
• Front crankshaft and camshaft seals — renewed to stop oil seepage around shaft exits
• Thermostat (82°C) and gasket — ensures correct engine operating temperature
• Accessory belts (A/C, alternator, power steering) included for a complete drive-belt refresh

Which Toyota models and engine codes is this compatible with?

This kit fits the 3.4L V6 5VZFE engine across several Toyota lines produced in the mid-1990s through early 2000s. Confirm fitment by matching year, model and engine code before ordering.

• 4Runner 3.4L — 1996–2002
• Tacoma 3.4L — 1995–2004
• Tundra 3.4L — 2000–2004
• T100 3.4L — 1995–1998

How does this kit help prevent future engine damage?

A properly timed engine is critical to valve and piston coordination; a failed timing belt can cause severe internal engine damage. By replacing the belt together with the tensioners, water pump and seals, you minimize the chance of related failures during the next service interval.

• New tensioners and rollers reduce belt misalignment and premature wear
• Fresh seals prevent oil contamination that can degrade belt material
• Replacing the water pump when belts are accessible avoids future labor duplication

What should I know about installation and customer support?

Installation requires moderate to advanced mechanical skill and standard engine timing tools; follow a service manual for torque specs and alignment marks. Nakuuly provides customer support to assist with part questions or fitment concerns if issues arise during installation.

• Refer to factory timing marks and tighten fasteners to specified torque values
• Inspect pulleys and engine mounts for wear while components are exposed
• Contact Nakuuly support for replacement part clarification or missing-item resolution

Who is this for: This kit is aimed at owners and technicians maintaining Toyota 3.4L 5VZFE engines who want a comprehensive, time-saving repair package. It’s well suited for preventive maintenance at the recommended timing interval, engine rebuild preparation, or when replacing a failed belt to ensure all related components are renewed in one service.
