When oil, heat, and abrasion combine to weaken most standard accessory belts, Continental OE Technology Series V-belts will still be going strong. Continental V-belts have inherited tough construction characteristics: EPDM rubber compounds, high-strength Vytacord tension members, fiber reinforced helical cogs, and high-traction rubber edges. These features provide higher heat and abrasion resistance, no-slip contact with pulley grooves, a great fit, and improved flexibility—to deliver consistent, efficient performance, mile after mile. Belts wear and need replaced; get more for your buck with longer-lasting Continental OE Technology Series V-belts, available for a wide range of vehicle-specific applications.

ACDelco V-ribbed serpentine belts resist the penetration of water, acids, and ozone--plus, they provide broad temperature tolerances. Their patented advanced technology design incorporates EPDM rubber, which stays soft and pliable longer than traditional belt materials. Neoprene and certain grades of rubber can harden, causing unwanted squealing and a shorter belt life. The flexible construction of these serpentines allows each belt to withstand many topside and backside bends. ACDelco offers their V-ribbed replacement belts in various lengths, widths, and rib quantities for a wide range of fitments.

These Dorman alternator combination mounting brackets are designed to mount to the front of GM 4-cylinder engines and hold the alternator, power steering pump, air conditioning compressor, and serpentine belt idler pulley. Many times, when the above accessories are removed for replacement, the mounting bolts, after years of exposure to the elements, will corrode and rust. This rusting reaction causes the bolts to become seized and they will usually break off when you are trying to remove them, making the entire bracket useless. So, pick up one of these Dorman alternator combination mounting brackets and get your vehicle running again.
