Diesel Engine Maintenance

We have all factory level software and trained technicians. Although diesel engines do not have distributors or spark plugs and therefore, do not require ignition tune-ups, you still need to have regular diesel engine servicing for maintenance and. For example, The "Ultra Low Sulfur Diesel Fuel" is HARSH on the system. Maintenance starts with clean oil and frequent services. Fuel filter will have to be changed with more frequency due to bacteria growing in the fuel tank. Engine lamps are now more harmful then good. Prolonging the "Engine Warning" lamp is a direct cause of DPF and Doc systems (exhaust after-treatment). More information can be obtained by calling or texting our service department (973) 729-3938.

Hayden’s Service Center specializes in diesel engine repairs and heavy-duty truck maintenance.


Our technicians are trained to use factory-level software and advanced diagnostic tools to accurately service modern diesel engines, emissions systems, and drivetrains.


Regular diesel maintenance is critical—especially in today’s trucks operating on Ultra Low Sulfur Diesel Fuel. Clean oil, frequent fuel filter changes, and addressing engine warning lights early are key to protecting your DPF, DOC, and SCR after-treatment systems. Ignoring warning lights can lead to major repair costs.


We proudly service all major diesel platforms including Cummins, Power Stroke, Duramax, International, Freightliner, Mack, and more.
