FAQ

Q1: How do I confirm this fan belt (178662) fits my specific NT855 engine?
A1: While the 178662 belt is a standard accessory drive belt for the Cummins NT855, we recommend verifying your current belt’s part number or measuring its length (typically around 50-60 inches for this application). Cross-check your engine serial number (ESN) with your local Cummins dealer or parts manual to ensure it matches the standard NT855 configuration.

Q2: What are the signs that my fan belt needs replacement?
A2: Common indicators include visible cracking, glazing (shiny surface), fraying on the edges, or a squealing noise from the engine bay. Also, check for belt slippage, which can cause engine overheating or a dead battery. Regular inspection every 500 operating hours is recommended for heavy-duty use.

Q3: Can I install this belt myself, or do I need a professional mechanic?
A3: Replacing the fan belt is often a straightforward task for a qualified diesel mechanic. However, it requires proper tensioning to avoid premature wear or damage to the water pump and alternator bearings. If you are not experienced with engine accessory drives, we recommend professional installation to ensure correct routing and tension (typically 90-110 lbs of force for a new NT855 belt).
