The 2008 Infiniti G35 features a serpentine belt system that powers essential engine accessories such as the alternator, power steering pump, and air conditioning compressor. Understanding the routing and maintenance of this belt is crucial for vehicle performance.

Overview of the Serpentine Belt

The serpentine belt is a single, continuous belt that snakes around multiple pulleys in your vehicle's engine. It is designed to drive various components, ensuring they operate efficiently. Over time, serpentine belts can wear out due to heat, friction, and environmental factors, leading to potential engine issues if not replaced timely.

Important Note: The belt should be installed with the grooved side against the pulleys that have grooves and the flat side against smooth pulleys.

Replacing the Serpentine Belt

To replace the serpentine belt on a 2008 Infiniti G35, follow these steps:

1. Preparation:

- Gather necessary tools: a breaker bar, sockets (10mm and 14mm), and possibly a torque wrench.

- Ensure the vehicle is parked on a level surface and turn off the engine.

2. Accessing the Belt:

- Remove any components obstructing access to the serpentine belt, such as the coolant overflow tank.

- Locate the tensioner pulley; use a breaker bar to relieve tension by turning it counter-clockwise.

3. Removing the Old Belt:

- Once tension is released, slide the old belt off the pulleys. Take note of its routing for reference when installing the new belt.

4. Installing the New Belt:

- Route the new serpentine belt according to the diagram.

- Ensure it sits properly in all grooves before applying tension.

- Reapply tension by releasing the tensioner pulley slowly.

5. Final Checks:

- Double-check that all components are secure and that there are no obstructions.

- Start the engine and observe for any unusual noises or misalignment.

Important Info: Regularly inspect your serpentine belt for signs of wear such as cracks or fraying, especially if your vehicle has over 60,000 miles.
