Product Details

The Motorcraft BT139 Belt Tensioner Pulley Assembly is a genuine OEM replacement component designed to maintain proper serpentine belt tension in Ford and Lincoln vehicles. This tensioner pulley assembly ensures consistent belt operation by automatically adjusting tension as the belt stretches over time, preventing slippage and premature wear.

Key Features:

  • Genuine Motorcraft OEM quality for precise fit and reliable performance
  • Complete pulley assembly with integrated tensioner mechanism
  • Designed to maintain optimal belt tension throughout service life
  • Reduces belt noise, vibration, and wear on driven accessories
  • Direct replacement for worn or failed original equipment

Regular inspection and replacement of the belt tensioner assembly helps prevent unexpected belt failure and protects critical engine accessories including the alternator, water pump, power steering pump, and air conditioning compressor. Motorcraft parts are engineered specifically for Ford, Lincoln, and Mercury vehicles to deliver OEM performance and durability.

Really easy and great pricing

Cheapest price for the same parts! Thanks!

Quick, easy, and best price I found for magnacor wires

Fgh

So far so good with great prices and part availability. Update: My only complaint is that you are told your items will be shipped via a premium shipper and you pay for that, but in the end your items are actually shipped via a much cheaper shipping option. So you are not getting the shipping that you are paying for! This seams very dishonest to me, not sure if I will order from here again or not.

First order, hard to say. Was the best price tho

Easy to deal with about shipping questions, great prices, and friendly customer service. One of the few places who says "I'll return you call" and actually does. Thanks...
