Product Details

The Dayco 89449 is a heavy-duty automatic belt tensioner designed to maintain proper tension on serpentine drive belts throughout their service life. This tensioner assembly automatically adjusts belt tension to compensate for normal belt wear and stretching, ensuring optimal performance of belt-driven accessories.

Key Features:

  • Heavy-duty construction for extended service life in demanding applications
  • Automatic tensioning system maintains consistent belt tension
  • Direct-fit replacement for original equipment
  • Precision-engineered components ensure reliable operation
  • Reduces belt noise and prevents slippage

Dayco automatic belt tensioners are manufactured to meet or exceed OEM specifications, providing reliable performance and durability. The tensioner assembly helps prevent premature belt failure and ensures proper operation of alternators, power steering pumps, air conditioning compressors, and other belt-driven components.

Amazing prices, cheapest I could find anywhere. Only down side is the shipping is more than it should be.

So far so good

Very happy with my purchase and product from Autoplicity! Highly recommend.

I was looking for KC lights for my jeep, not only CI they have just the ones I was looking for, they were half the price of any local auto shop! Shipping costs were very low to. Thanks!

I bought a set of 3 MSD Ignition coils for my 2001 Impala LS 3.8 and I am very impressed and satisfied with my purchase. I got an email right away stating what I purchased and within a day or two I recieved a shipping confirmation. My ignition coils arrived fast and I had no problem with the coils been bad or broken. The coils are awesome. There is a significant difference between my old ones and these 3 new ones. The car is very responsive to the accelerator and as stated in the MSD website, the car gained some horsepower. I don't have to press the accelerator in that much to gain the power I need. I'm impressed overall.

Great product and half the price of any one else I've shopped would recommend this to everyone.

autoplicity has the lowest price and fast service .I will definitely use autoplicity for my next auto parts purchase

At first I did not expect Autoplicity to even carry this part, but in fact they did. Placed the order and I received the part quickly. They were the cheapest for the part after searching nearly everywhere. Will order from them again.<br>Order #8334

Great Prices much cheaper than going through the high dollar mail order companies. Same product and I saved about 50 bucks!

I ordered the Truxport tonneau cover for my Nissan Frontier. I am very happy with Autoplicity,they have the best price by far on this product,and they promptly sent me an email when it was shipped.....the ONLY thing I wish they would have done but didn't is to include a tracking number. I think the reason they didn't include it is that it was shipped directly from the manufacturer,but they did give me the tracking number when I called and asked for it. Overall a very positive experience

Great prices and very quick shipping! Thanks
