1990 CAT 3116 Engine For Sale
About This 1990 CAT 3116 Engine
The CAT 3116 is a 6.6-liter inline-six diesel known as the direct predecessor to the CAT 3126. Many units are turbocharged, while some are naturally aspirated, and ratings commonly range from roughly 170–300 HP depending on the application. Fuel systems also vary by year between mechanical and HEUI arrangements. The 3116 powered Freightliner FL, GMC and Chevrolet Topkick and Kodiak medium-duty trucks, buses, marine applications, and equipment. That mix of road, passenger, marine, and equipment use makes the exact engine configuration important when choosing a used replacement. Used CAT 3116 engines stay in demand because owners maintaining these applications need a model-correct engine rather than assuming another CAT inline-six will fit. This 1990 3116 should be matched to the original truck, bus, marine, or equipment application and its year-specific configuration. Every CAT 3116 engine we sell is inspected and tested before it ships, identified by its stock number (218630-12), and backed by included warranty coverage. Freight ships nationwide and is quoted to the delivery ZIP. Before buying, have the truck or coach's year, make, model, and application ready so our parts team can confirm fitment — call (800) 696-5459.
