Eliminate your squeaking accessory belt pulley and cracked drive belt with this upgraded accessory belt service kit! This kit includes the ECS Kevlar Reinforced Drive Belt, tensioner assembly, and idler pulley. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

Accessory drive belts are essential for keeping your engine's components running smoothly off the crank pulley. These belts power the generator, fans, water pumps, and AC compressors, ensuring everything functions properly. If your drive belt shows signs of aging, such as cracking, glazing, or squeaking, it's time for a replacement.

Signs of wear are easy to spot. The underside of the belt will start to glaze, reducing its effectiveness. Cracks can develop on the back due to "dry rot" from exposure to engine heat or age. Squealing noises indicate the belt is slipping on the pulleys. In any of these cases, it's clear your vehicle needs a new belt.

Our drive belt is designed for long-lasting performance, keeping your accessories running efficiently. A worn belt can cause your accessories to work below their optimal capacity. Don't wait for a belt failure—include it in your next maintenance plan to ensure your vehicle remains in top condition.

Accessory drive belts keep everything turning off of the crank pulley. Generator, fans, water pumps and AC compressors all rely on this belt to keep everything working properly. If your drive belt is getting old, cracking, glazing, or squeaking, replace it. It's easy to see when the belts are beginning to wear. Visually, the belt will begin to glaze on the underside, making it far less effective. Cracks can appear on the back of the belt from “dry rot” caused by exposure to engine heat or age. Squealing is common on worn belts which basically means that the belt is slipping on pulleys. In either case, your vehicle needs a new belt. Designed for long life, this belt will keep everything turning great and all of your accessories working properly. With a worn belt, accessories aren't working at maximum efficiency. Do not wait for this belt to break to replace. Replace it as part of your next maintenance plans.
