[CONTACT US](https://rolonmobiletruckrepair.com/contact-us?hsLang=en) ## Your Semi-Truck Engine Repair Questions, Answered We get many questions about semi-truck engine repairs. Here are some of the most common ones, with our answers: ### 1. What engines do semi-trucks have? Most Class 8 semi-trucks in North America are powered by large-displacement inline-six cylinder diesel engines. The most prominent manufacturers you'll find on the road are Cummins (like the X15), Detroit Diesel (DD series), PACCAR (MX series, found in Kenworth and Peterbilt), and Volvo/Mack. At Rolon, our technicians have over 40 years of hands-on experience servicing all of these major diesel engine brands. ### 2. How many cylinders are in a semi-truck engine? The vast majority of modern semi-truck engines use an inline-six cylinder configuration. This design is favored for its excellent balance, reliability, and ability to produce the high torque needed for hauling heavy loads. While other configurations have existed, the inline-six has become the industry standard for heavy-duty trucks. ### 3. How long do semi-truck engines last? A well-maintained semi-truck engine is built for the long haul, typically running for 750,000 to 1,000,000 miles before needing a major overhaul or rebuild. The actual lifespan depends heavily on factors like consistent regular maintenance, operating conditions, and driving habits. With proper care, a professional truck engine rebuild can often give it a second life. ### 4. How much does a semi-truck engine cost? The cost of a new semi-truck engine can vary significantly, typically ranging from $25,000 to $40,000 or more. The final price depends on the manufacturer (Cummins, Detroit, etc.), the specific model, and whether it is a brand new or a remanufactured unit. When considering a truck engine replacement, it's important to factor in labor costs as well. For a precise quote based on your truck's needs, contact our expert team. ### 5. How much does it cost to rebuild a semi-truck engine? The cost to rebuild a semi-truck engine is generally less than a full replacement, often falling in the $10,000 to $20,000 range. The final cost depends on the extent of the damage and which components need to be replaced (e.g., a basic in-frame overhaul vs. a complete rebuild). A professional truck engine overhaul can be a very cost-effective way to restore your engine's performance. Contact us for a detailed assessment and quote for your specific engine. ![rolon-mobile-truck-repair-logo](https://rolonmobiletruckrepair.com/hs-fs/hubfs/rolon-mobile-truck-repair-logo.png?width=220&height=171&name=rolon-mobile-truck-repair-logo.png "rolon-mobile-truck-repair-logo") ###### ABOUT US With over 40 years of experience, our team offers 24/7 professional, reliable, and efficient repair solutions, ensuring minimal downtime for drivers.
