FAQ SECTION
What are the common signs a Cummins marine diesel needs service?
Look for excessive smoke (black, white, or blue), a noticeable loss of power, “temperature creep” during cruising, or unusual vibrations. These often indicate air/fuel issues or cooling system scale buildup.
Do you work on the Cummins QSB and QSC series?
Yes. We specialize in the modern Quantum Series (QSB, QSC, QSL, QSM) engines, including EVC diagnostics and electronic sensor troubleshooting.
Why should I use Fleetguard filters on my Cummins?
Fleetguard is Cummins’ own filtration brand. Using these filters ensures the micron rating and flow capacity perfectly match your engine’s requirements, preventing fuel system damage.
Can you perform a Cummins engine survey for a boat purchase?
Absolutely. We provide comprehensive pre-purchase engine surveys in NJ, including oil analysis, compression testing, and a full electronic health report for any Cummins-powered vessel.
