Product Details

The ACDelco Gold 38315 is a 90-degree molded accessory drive belt tensioner assembly designed as a premium aftermarket replacement for original equipment (OE) parts. Also referenced by OEM part number 19188403, this tensioner assembly plays a critical role in the proper operation of the accessory belt drive system by maintaining consistent tension on the serpentine belt throughout engine operation.

Proper belt tension ensures that key engine accessories — including the alternator, power steering pump, water pump, and air conditioning compressor — receive reliable power transfer and continue to operate smoothly and quietly. A worn or failed tensioner can lead to belt squeal, slippage, battery charging issues, or premature belt wear.

Key Features:

  • 90-degree molded design for precise OE fit and straightforward installation
  • Maintains correct serpentine belt tension automatically as the engine runs
  • Machined exterior finish for durability and consistent performance
  • Manufactured to meet OE specifications for fit, form, and function
  • Premium aftermarket quality — part of the ACDelco Gold (formerly ACDelco Professional) line
  • Includes tensioner assembly with integrated pulley

The ACDelco Gold 38315 is a dependable, direct-fit replacement tensioner that installs exactly like the original part — no modifications required. Cross-references OEM part number 19188403.

I ordered a Thule bike rack for a birthday gift late on Friday night. I got the shipment notice on Monday morning and it was delivered on Tuesday morning. It's exactly what I was looking for, at a great price, and Autoplicity made it very easy! I couldn't be more satisfied!

Autoplicity has great pricing, super easy to navigate, quick shipping and service, Thanks

Got what I ordered in good condition and in a reasonable amount of time, looks like a good product, I guess time will tell

So easy and quick.

Ordered the ARB 50QT fridge from Autoplicity b/c they had every merchant beat by more than $100. Very happy with the transaction and would highly recommend - best prices bare none. I called Auto Anything and was told they match pricing with most vendors - except Autoplicity. I can see why. My first order but not my last!

Great

I like the cost per unit, but the shipping is a little high

Quick service

Cool site.

The kit I needed was available at the best price on Autoplicity. I asked a question by live chat. It was a slow response, but once my question was forwarded to the appropriate source, the response was quick, helpful and professional.
