Restored proper cooling and quiet operation
Installed this remanufactured Drivemaster two-speed fan clutch on a PACCAR MX13 after dealing with inconsistent fan engagement and unnecessary cycling. Fitment was exact to OE with no modifications required. Fan engagement is now smooth and predictable under load, and it disengages correctly at cruise, reducing noise and drag. Unit arrived clean, well-packaged, and clearly inspected. Cooling behavior is back to normal and engine temperatures are stable. Solid reman solution when OEM lead times or costs aren’t practical.
