Product Details

The Gates 38078 DriveAlign Accessory Belt Idler Pulley is a direct-fit OE replacement engineered to maintain proper serpentine belt tension and routing in the accessory drive system. Built to thermoplastic construction with premium-grade sealed bearings, this idler pulley is designed to handle the demanding environment found under the hood of passenger cars and light trucks.

Key Features:

  • OE-quality fit: Meets or exceeds original equipment specifications for a direct, hassle-free installation
  • Premium bearings: Application-specific speed and load ratings allow bearings to withstand high under-hood temperatures while eliminating bearing noise
  • Thermoplastic construction: Provides high durability while resisting heat, vibration, dirt, salt, and other under-hood contaminants
  • Smooth contact surface: Backside/smooth design for proper serpentine belt routing
  • Key Dimensions: Bearing bore I.D. 24.5mm / 8.2mm, outside diameter 90mm (approx. 3.54 in.), width approx. 25mm (0.984 in.)
  • Sold individually: One pulley per package

The Gates DriveAlign idler pulley assists in driving critical engine accessories including the air conditioning compressor, alternator, power steering pump, and water pump. By maintaining correct belt tension and alignment, it also reduces wear and friction on the serpentine belt itself, extending overall belt service life.

Great site. I received my product quickly and it was the product I ordered.

quick and easy using amazon

Autoplicity has the best prices around! They were quick to email a confirmation of the order, shipment, and delivery. I was VERY impressed! I also received my order earlier than I thought, which is always a plus. Will definitely do business with them again! Thanks!

I fount this VW motor mount at 75% off what Auto zone want ...what a deal I'm coming back for sure

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Quick shipping and good communication, thanks!
