What’s Included in the Fordnova Belt Drive Kit?
1. EPDM Serpentine Belt
The included serpentine belt is manufactured from EPDM rubber designed to resist the heat and repeated flexing associated with engine accessory drive operation.
Its construction helps resist:
- High underhood temperatures
- Cracking and deterioration
- Premature wear
- Repeated flexing
- Surface deformation
The belt transfers rotational power from the engine crankshaft to compatible belt-driven accessories.
2. Automatic Belt Tensioner
The automatic tensioner helps maintain the correct belt tension as the engine operates.
A worn or weakened tensioner can contribute to:
- Belt slipping
- Excessive vibration
- Abnormal belt tracking
- Squealing or chirping noises
- Premature belt wear
Replacing a worn tensioner can help restore proper belt engagement and accessory drive performance.
3. Replacement Idler Pulley
The idler pulley helps guide the serpentine belt through its designated routing path.
A worn idler pulley bearing may produce grinding, chirping or rattling noises.
Replacing a damaged or noisy pulley can help restore smooth belt operation.

Common Ford 4.0L V6 Serpentine Belt Problems
The Ford 4.0L V6 accessory drive system relies on proper belt tension, pulley alignment and smooth bearing operation.
Over time, worn components may cause:
- Squealing during startup
- Chirping at idle
- Belt slipping
- Excessive belt vibration
- Tensioner pulley noise
- Idler pulley bearing noise
- Uneven belt wear
- Accessory drive problems
A worn tensioner or damaged idler pulley can cause a new belt to wear prematurely.
Inspecting the complete system helps identify the cause of recurring belt problems.
Why Replace the Belt, Tensioner and Idler Pulley Together?
Replacing multiple worn accessory drive components during the same repair can help reduce repeat maintenance.
Advantages may include:
- Less repeated disassembly
- Improved belt tracking
- Restored belt tension
- Reduced pulley bearing noise
- Lower risk of premature belt wear
- More convenient preventive maintenance
However, a functioning tensioner or idler pulley does not automatically require replacement whenever the serpentine belt is changed.
Inspect the existing components and follow the vehicle manufacturer’s service recommendations.
How to Replace the Ford 4.0L V6 Serpentine Belt and Tensioner
Proper installation is important for belt life and reliable accessory drive performance.
