Dayco Automatic Serpentine Belt Tensioner 132004

PRODUCT OVERVIEW

The Dayco Automatic Belt Tensioner 132004 is engineered to maintain constant, correct tension on modern serpentine belt drives. It helps prevent belt slip, noise and premature accessory wear by automatically compensating for belt stretch and engine operating conditions.

KEY FEATURES

• Helps reduce belt squeal, slippage and poor accessory performance.
• Designed for serpentine belt systems driving multiple engine accessories.
• Engineered to meet or exceed OEM performance requirements.

CONSTRUCTION & MATERIALS

• Heavy-duty cast aluminium spring case resists cracking and fatigue.
• Cast aluminium arm for high strength and minimal distortion.
• Steel locator pin and steel pivot tube (where required by application) for critical torque strength.
• Aluminium retainer ring locks spring case and arm together and seals against corrosion.
• Teflon® strip wound within the spring to reduce abrasion and extend service life.
• Flat spring coated for enhanced rust and corrosion resistance.

NOISE REDUCTION & DURABILITY

• Lubricated nylon pivot tube bushing and spring bushing for quieter operation.
• Thermoplastic rubber spring slot plug to keep out harmful contaminants.
• Rubber O-ring seal to protect internal components from dust and grime.
• Zinc-coated mounting bolt for corrosion resistance and even, stable tension.

PULLEY DESIGN

• Supplied with either a glass-filled polymer or steel pulley (depending on application).
• Pulley incorporates a dust cover to protect the bearing from contaminants.
