Timing Belts & Chains Replacement – Toyota 4Runner – Englewood, Colorado
Your Toyota 4Runner’s timing system is built for endurance—whether it’s tackling mountain trails or city commutes. At TurboSpeed Auto Sales LLC in Englewood, Colorado, we perform OEM-spec timing belt and timing chain replacements using factory tools, Toyota FIPG sealants, and torque-to-yield hardware for precision and longevity.
We service every generation of 4Runner, from classic V6 models with belts to modern Dual VVT-i chain-driven engines, restoring quiet starts, smooth power delivery, and dependable performance.
Why Timing Service Matters
- Prevents catastrophic valve or piston damage on interference engines.
- Restores proper cam/crank synchronization for strong torque and smooth running.
- Eliminates chain rattle, belt slip, or phaser noise that can trigger VVT codes.
- Extends engine life with OEM parts, correct sealants, and fluid specs.
4Runner Engines We Service
- 4.0L V6 (1GR-FE): chain service, guides, tensioners, and VVT-i actuator inspection (Dual VVT-i 2010+).
- 4.7L V8 (2UZ-FE): timing belt service, idlers, tensioner, cam/crank seals, water pump.
- 2.7L I-4 (3RZ-FE / 2TR-FE): chain service with tensioner/guides, oil control valves, seals, and cover reseal.
- 4.6L / 5.7L V8 (UR Series – swap/custom builds): timing chain, phaser calibration, and seal refresh.
Note: Most 4.0L and 2.7L Tacomas/4Runners use chains, while the 4.7L V8 uses a belt. We verify engine type by VIN for correct parts and labor estimate.
Signs Your 4Runner Needs Timing Service
- Rattle at cold start, chain slap, or VVT actuator tick.
- Cam/crank correlation codes (P0016–P0019) or VVT performance codes.
- Rough idle, misfire under load, or low power.
- Oil or coolant leaks around the timing cover or water pump area.
- High mileage (90K–120K) on 4.7L V8 without previous belt service.

FAQs
Do you use OEM parts?
Yes—Toyota Genuine or premium equivalents (Aisin/INA/Denso) with all factory torque values.
When should I replace the timing belt?
Every 90K–105K miles on 4.7L 2UZ-FE engines, or sooner if oil leaks are found.
Should I replace the water pump at the same time?
Yes—on belt engines it’s driven by the timing system, making this the ideal service time.
