Diesel Engine Models from Other OEMs – Repair Advice, Maintenance Tips & Parts You Can Trust

Not every engine on the road is a Cummins, Caterpillar, or Detroit—and at Highway and Heavy Parts, we know that many operators run equipment powered by less common diesel engine brands. Whether you’re running an older or specialty model from OEMs like Paccar, Hino, Isuzu, Case/New  Holland, or others, we’ve built this blog directory to help you keep your engine running strong.

Our Other OEMs blog category features in-depth repair guides, troubleshooting strategies, and parts recommendations tailored to lesser-known engines—without sacrificing quality or accuracy.
