Detroit Diesel A4722001370 Belt Tensioner Replacement For Freightliner Cascadia 08-17

Aftermarket accessory drive belt tensioner for Detroit Diesel DD13, DD15, and DD16 engines — the front-of-engine 10-rib serpentine tensioner. A4722001370 supersedes the earlier A4722001070 (EA4722001070) and the later A4722001570 / A4722001670 family. Detroit revised the tensioner across model years with revised pulley diameters; this one fits Freightliner Cascadia, Coronado, M2 (with DD13), Western Star 4700 / 4800 / 4900, and earlier Century / Columbia chassis equipped with DD13 or DD15.

Signs You Need a New Belt Tensioner

• Squeal or chirp from the front of the engine, especially under load
• Visible belt slip, glazing, or rapid edge wear
• Pulley wobble or play when the engine is off
• Rust streaks, leaking grease, or seized hydraulic damper at the tensioner arm

Detroit revised the tensioner across the production run; verify your engine serial number / build date before ordering — the supersession chain is not always backward-compatible without changing the belt as well.

Damaged Shipments
All Pro Truck Parts is not responsible for damage that occurs in transit - responsibility for damaged shipments lies with the carrier. However, we are glad to assist by filing a claim with the carrier on your behalf.

If your package arrives damaged, please do the following:

1. Refuse delivery if the package is visibly damaged at the time of arrival, and note the damage with the driver.
2. If the damage is discovered after delivery, photograph the outer packaging BEFORE opening the box, then photograph the contents showing the damage.
3. Keep all original packaging, including boxes, packing materials, and labels. Carriers may require an inspection before approving a claim.
4. Notify us within 48 hours of delivery by submitting a damaged shipment report at help.allprotruckparts.com/damaged-shipment.

Once a claim has been filed, resolution is determined by the carrier. Refunds and replacements for damaged shipments will only be issued after the carrier approves the claim. Failure to report damage within 48 hours, discarding the original packaging, or opening a visibly damaged package without photographing it first may result in the carrier denying the claim, in which case we are unable to refund or replace the item.
