Product Details

The ACDelco 15-40486 (also known as ACDelco Gold / Professional part 19190157) is an Air Conditioning Drive Belt Idler Pulley designed to route the serpentine drive belt to engine accessory components. This pulley is specifically engineered for applications where the A/C compressor is driven by a separate dedicated belt, keeping accessory drive systems operating smoothly and reliably.

Key Features:

  • ACDelco Gold (Professional) Series — a high-quality aftermarket alternative to OE parts, manufactured to meet or exceed OE specifications for fit, form, and function
  • 6-Groove serpentine design — grooved profile matches standard serpentine belt ribbing for secure, low-slip belt engagement
  • Plastic construction — lightweight and resistant to corrosion and heat in the engine bay environment
  • Clutch diameter: 69.85 mm (2.75 in) — precision-sized for accurate belt alignment and tension
  • Black finish — standard OE-style appearance
  • Backed by General Motors — ACDelco Gold parts are supported and validated by GM engineering standards

Part number cross-references: 15-40486 / 1540486 / 19190157. This pulley is a direct-fit replacement that installs without modification, making it a straightforward swap for worn, cracked, or seized OE pulleys. A failed idler pulley can cause belt squealing, belt misalignment, or complete belt failure — replacing it promptly helps protect downstream accessories including the A/C compressor, alternator, and power steering pump.

Great Price, the best I found on the internet. And they shipped quickly. Also, it was easy to pay. I used pay with Amazon, and it just picked up all my information. Could not be easier.

This copany shipped my order promptly. I would do business with them again.

easy

After reading several negative reviews, I was suspicious of the low price offered by Autoplicity but decided to try them out anyway. Much to my surprise, the belt for my car shipped immediately and arrived 2 days later via ground shipping from half way across the country. I was very pleasantly surprised with the speed of service and got my parts for the lowest price on the internet. A+!

Had problems using the search tool so I called direct. They helped locate Air Lift shocks I needed and told me that I.E. browser is sometimes a problem. They were helpful and my items got shipped the next business day.

Great price reasonable shipping rate

gREAT SERVICE GREAT PRICE

they were able to answer any questions i had and shipped the item out the next day. great to do business with. i will be ordering from them again.

This my first time to purchase from this company and it was easy and fast. I will be back!!!

Good Prices and easy to use

This has been one of the fastest checkouts I've experienced in my years of parts purchasing as a DIY'er.

Excellent experience. Cheapest price I could possibly find, reasonable shipping cost (other people tried to charge upwards of $20 where I was only charged $14). Shipping was VERY quick. <br><br>I was slightly weary of ordering from Autoplicity as I had never heard of them before but from here on out they will be the first place I check. Could not be happier. <br><br>There is nothing that could have made this experience more enjoyable for me.

ALL GOOD

Autoplicity had the part I needed at the best price I could find anywhere, and with their quick shipping I had the part in less than a week. Thanks Autoplicity
