When the need for rugged, heavy-hauling diesel engines calls, Hino answers. Hino specializes in robust and durable diesel engines, all of which power their own and other vehicle manufacturers' large commercial vehicles like buses and trucks that see high daily mileages and demand minimal downtime for repairs. With a Hino engine, you know you'll be in it for the long haul.

No matter how durable Hino engines might be, there could come a time when they fall victim to wear and tear or a rare manufacturing defect and require replacement. Make sure you know all you need to know about Hino engines, like where to source them, their unique technologies, notable engine series, and how to take care of them, so that you'll be ready to seek out a replacement and maintain it (or your current engine) in prime condition.

Key Features of Hino Engines

Fuel Efficiency

Hino engines are known for their exceptional fuel efficiency, which translates to lower costs for covering long distances.

Durability & Longevity

Engines from Hino are built to last. And they have to be with all those heavy kilometers they put in. Hino is so confident in their engines that they offer the industry's best warranty coverage for both engines and vehicles.

Emission Control Technologies

Hino is dedicated to reducing emissions from its engines and vehicles. They have integrated their diesel engines with advanced technologies such as Selective Catalytic Reduction. It's an active emissions control system that regulates the volume of emissions by injecting a liquid-reduction agent through a specific catalyst into the engine's exhaust stream.

Sourcing Hino Engines (OEM vs. Aftermarket)

When you purchase a brand new Hino, it comes with an Original Equipment Manufacturer (OEM) engine made by Hino or its authorized manufacturers. Engines made by third-party manufacturers and usable in Hino fall under the "Aftermarket" parts category.

Unless your Hino engine is out of production and impossible to find, we recommend investing in an original Hino engine to return your car to its original level of performance. Because of the more stringent levels of manufacturing, you'll likely get more use out of an OEM replacement. When installing aftermarket engines, they will not be covered by Hino's warranty and could also void the warranty and damage the vehicle. Moreover, they might not even fit into your Hino's engine bay properly. When it comes to an expensive part like the engine, it's prudent to avoid taking chances and to go with the original.

Types of Hino Engines

Diesel Engines

Diesel engines offer better acceleration, fuel efficiency, and hauling potential. As such, in addition to being used in passenger cars, they are also widely applied in heavy vehicles. Hino's diesel engines range in displacements from 4.0L up to 13.0L.

Hino's diesel engines have consistently performed well in the J.D. Power and Associates U.S. Medium-Duty Truck Engine and Transmission Study, standing out among the competition in the metrics of reliability and dependability, fuel economy, and vibration at idle.

Engines Used in Hybrid Cars

Hino has been a long-time proponent of hybrid technology for their cleaner emissions and greater fuel efficiency. As found in the Hino 300 Series Hybrid light-duty truck, one of their hybrid systems uses the diesel N04C-UL in conjunction with an electric motor to achieve a class-topping 13.2 km/l.

Notable Hino Engine Series

J Series

Hino's J Series of four-, five-, and six-cylinder engines are world-renowned for their performance, reliability, lightweight, and ease of installation and care. Technologies like common-rail fuel injection and a Zexel fuel injection pump in some J engines allow them to achieve lower emissions, greater fuel efficiency, and more horsepower.

N Series

The N Series is an environmentally friendly and powerful engine that allows Hino's 300 series to achieve a class-topping combination of horsepower and torque. Its standout features include a high-pressure common-rail fuel system, a variable-nozzle turbocharger, a cooled exhaust-gas recirculation system, closed crankcase ventilation, and a best-in-class Diesel Particulate Active Reduction (DPR) system.

E Series

The E13C engine is the mainstay of Hino's E series. These heavy-duty six-cylinder 13.0L engines boast exceptionally low emissions and fantastic fuel efficiency thanks to Hino's DPR Diesel Particulate Reduction particulate filtering technology and a combined exhaust gas recirculation system.

W Series

Hino built the 4.0L W inline four-cylinder engine with direct injection and water-cooling for use in the Toyota Dyna, Toyoace, and their Hino 300 Series. American motorboat manufacturer Bayliner even used this dependable engine in their 32 Motoryacht.

Maintenance & Care of Your Hino Engine

To realize your Hino engine's fullest potential, both in terms of performance and longevity, you must pay attention and care for it properly. Given the high cost of an engine replacement, you'll be doing a favor for your Hino engine and your wallet.

Key Routine Maintenance Tasks

Performing simple maintenance tasks can help keep your vehicle in good condition:
1. Regularly change the engine oil to keep the parts lubricated.
2. Check and maintain the coolant levels.
3. Be aware of any leaks and address them promptly.
4. Replace the spark plugs, wires, and fuel filters when necessary.

Common Issues & How to Address Them

You might encounter these common engine issues along the course of ownership of your Hino. One possible cause of engine overheating is a leak in the cooling system, a malfunctioning water pump, a faulty radiator fan, a defective thermostat, or low engine oil levels. Another is engine noises due to anything from a bearing to a timing shaft problem. Fixes for these will involve repairing or replacing the necessary parts or topping up engine oil. If significant damage to the engine has already occurred, you may need to replace the entire unit.

A faulty exhaust gas recirculation (EGR) valve can create problems like engine knocking, rough idling, and a drop in engine performance. Fortunately, these can be replaced individually without needing a whole engine overhaul.

Are Hino Engines Expensive?

Hino engines are not expensive compared to similar-sized equivalents from other manufacturers. They also break down less often, so you'll spend less on them in the long run.

Where to Buy Genuine Hino Engines Online

Brand-new OEM crate engines can be purchased directly from your country's Hino and OEM parts retailers. A less costly alternative with minimal compromise would be a second-hand Hino engine. You can find these in great condition and at affordable prices here at BE FORWARD Auto Parts.
