Product Details

The Dayco 85046 Hydraulic Timing Belt Actuator is a precision-engineered component designed to maintain optimal timing belt tension throughout your engine's operation. Also known as a hydraulic timing belt tensioner, this actuator automatically compensates for changes in belt tension caused by variations in engine temperature, speed, and normal belt wear over time.

Key Features:

  • Maintains constant timing belt tension during crankshaft revolution
  • Reduces engine noise and prevents belt flapping
  • Ensures proper timing effectiveness throughout the belt's service life
  • Manufactured to meet or exceed OE quality standards for form, fit, and function
  • Direct-fit replacement for simplified installation
  • Hydraulic design provides consistent performance under varying operating conditions

This timing belt actuator helps ensure reliable engine timing performance and extends the service life of your timing belt system. The hydraulic mechanism automatically adjusts to maintain proper belt tension, reducing the risk of premature belt failure and maintaining optimal engine synchronization.

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

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!

Great, easy!

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.

woohoo

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

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
