A Guide to the Serpentine Belt for the 2000-2001 Workhorse FasTrack FT1600
Keep your FasTrack FT1600's engine accessories running reliably with the correct new serpentine belt.
- A failed serpentine belt will disable your FT1600's engine cooling and power steering, making it undrivable.
- For the 5.7L V8 engine, ensure you purchase the correct 6-rib belt, which is approximately 87 inches long.
- Both Gates and Continental are trusted aftermarket brands that provide OEM-quality performance for this vehicle.
- Always inspect the belt tensioner and idler pulleys when replacing the belt; it is best practice to replace them at the same time.
Is Your FasTrack FT1600 Serpentine Belt Failing?
A serpentine belt is a wear item that requires regular inspection. On a hard-working commercial chassis like the FT1600, heat and constant use can cause the belt's EPDM rubber to crack and wear out. A belt rarely snaps without giving some warning signs first. Recognizing these signs can help you avoid being stranded.
Choosing the Right Aftermarket Belt: Continental vs. Gates
For the 2000-2001 Workhorse FasTrack FT1600, aftermarket belts from top brands offer quality that is equal to or better than the original factory belt. Both Continental and Gates are excellent choices, known for making durable EPDM rubber belts.
- Gates: Gates is a highly respected brand in the heavy-duty and commercial vehicle world. Many professional mechanics and fleet owners trust Gates for its reliability and precise fit. For a vehicle like the FT1600, a Gates belt is a solid, dependable choice.
- Continental: Continental belts are also known for their OEM-quality construction. They are particularly well-regarded for their unique design that can help quiet down a noisy belt drive system, which can be useful if you have persistent chirping noises.
Pro Tip: Check the Pulleys! While the serpentine belt is off, it is critical to inspect the belt tensioner and any idler pulleys. Spin each pulley by hand. If you hear any grinding noises or feel any wobble or roughness, the pulley's internal bearing is failing and it must be replaced. A bad pulley can destroy a brand-new belt very quickly.
Estimated Replacement Costs
The total cost to replace the serpentine belt depends on whether you do the job yourself or hire a professional mechanic. Below are estimated costs for the parts and labor.
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Serpentine Belt | $55.20 - $70.54 |
| Shop Labor | $120 - $180 |
| Total Estimated Cost (Installed) | $175.20 - $250.54 |
Common Ordering Mistake: The 5.7L engine in the FT1600 uses a 6-rib belt that is approximately 87 inches long. Workhorse used different chassis and engine combinations that require much longer belts. Always confirm the part fits your specific 5.7L engine to avoid getting the wrong length.
Frequently Asked Questions (FAQ)
How often should I replace the serpentine belt?
As a general guideline, serpentine belts should be inspected annually and replaced every 60,000 to 90,000 miles, or about every 6-8 years, whichever comes first. For a commercial vehicle that may idle frequently or sit for periods, age is often a more important factor than mileage, as the rubber can become brittle over time.
Is a squealing noise always a bad belt?
Not always. While a worn belt is the most common cause, squealing can also be caused by a weak belt tensioner, misaligned pulleys, or fluid contamination (like oil or coolant) on the belt. A thorough inspection is needed to find the true cause.
Should I replace the tensioner and pulleys with the belt?
Yes, it is highly recommended. The tensioner and idler pulleys have a service life similar to the belt. Replacing them all at once is the most reliable repair and ensures the new belt won't be damaged by a failing pulley.
Were there any recalls for the FT1600 serpentine belt?
No. As of early 2026, searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any safety recalls for the serpentine belt system on the 2000-2001 Workhorse FasTrack FT1600.
