Located at 2406 PA-412, Hellertown, PA 18055, Modern Diesel Service operates as a diesel repair shop serving Hellertown in Pennsylvania. This page gathers the practical details people usually look for before visiting: where it is, how to reach it, when it opens and how customers rate it.

Auto repair in the United States is split between independent shops, dealership service departments and national chains. Independents handle most routine work (oil changes, brakes, tune-ups, check-engine diagnostics) at lower labor rates and often specialize in one make or in imports; dealers keep factory tools, software and warranty authority; chains sell speed and standard pricing on maintenance items. Most shops charge a diagnostic fee, credited toward the repair if you go ahead, and quote parts and labor separately. Certification matters: look for ASE-certified technicians and, in many states, a state repair license posted at the counter. Written estimates are required by law in most states before work begins, and you are entitled to your old parts if you ask.

Hours are published for 5 days a week. On most of those days it is open 8 am–5 pm. Note that it does not open on Saturday, Sunday. Hours in the United States do change around federal holidays and long weekends, so a quick call before a special trip is sensible. The listed phone number is (610) 570-5407. Many businesses also reply to text messages on the same number if it is a cell phone.

Customers rate it 5.0 out of 5 on Google across 22 reviews, placing it among the better-regarded diesel engine repair in Hellertown.
