The Detroit Diesel History
First produced in 1987. It was the first commercially available on-highway heavy-duty diesel engine to have full “drive-by-wire”.
It was many years before another engine manufacturer launched a drive-by-wire system.
The Detroit Diesel 60 Series has a cast-iron block and is wet-sleeve. This engine is widely used in straight trucks and in tractor-trailer configurations.
Detroit 60 Specs – 4 Stroke Diesel Engine
The (original) 1987 version had 11.1 L (677 cu in). Rated at 350 bhp (260 kW); 1,250 lb-ft @ 1,200 RPM.
In 1993, Detroit Diesel added a second version with 12.7 L (778 cu in).
Rated at 455 bhp (340 kW); 1,550 lb-ft @ 1,200 RPM. Both the 11.1 L and 12.7 L engines were available at this time In 1998, the 11.1 L engine was discontinued.
In 2001, Detroit Diesel added a third version the 14L (854 cu in).
Rated at 575 hp (429 kW); 1,650 lb-ft @ 1,200 RPM. Both the 12.7 L and 14 L engines were available at this time.
Out With The Old
In 2007 the 12.7 L engine was discontinued. In 2008 the 14 L was modified to meet the EPA’s new emission standards.
Those new emission standards were Dual ECM & DPF exhaust filter. In 2011 the Detroit 60 series engine was discontinued, and replaced with the DD15 engine.
Detroit 60 with DDEC
The Detroit Diesel on-highway-engine drive-by-wire system was the proprietary Detroit Diesel Electronic Control (DDEC) system. The DDEC system included engine diagnostics, fault history, shutdown timers, speed limiting, and cruise control. The DDEC provided owners with records of over-speeding, idle time, hard braking, etc.
Large fleet owners can purchase scanners that download all DDEC’s records. Small fleet owners can have their trucks’ DDEC scanned at a local Detroit Diesel dealership.
The DDEC also allows owners to “de-tune” engines; a process that turns down an engine’s top horsepower. To encourage a driver to use the speed control (to conserve fuel), The DDEC can be programmed to provide an additional 15 bhp while the speed control is switched on. (This number can be programmed by the truck’s owner.)
DDEC Increase Detroit 60 Engine Benefits
All of these features allow a truck owner to reduce engine abuse, maximize fuel economy, and decrease idle time. In company trucks, these features are made available to owners, but unavailable to drivers.
The DDEC has two engine fault lights; the yellow “minor fault” light and the red “significant engine fault” light. The yellow light warns a driver of a potential problem. The red light is nick-named the “STOP THE TRUCK RIGHT NOW!!” light. Often, the red fault light will proceed an automatic engine shut-down.
Diagnostic Information – Added Benefit of Detroit 60 engine
A driver can obtain basic diagnostic information from the DDEC by pressing a button in the cab of the truck.
When pressed, the red and yellow fault lights blink in a various patterns.
By noting the color of the light, counting the flashes, and consulting a look-up-table in the engine owner’s manual—a driver can get a rough idea of the engine’s condition.
Knowing the engine fault code helps a driver and his mechanic know what sort of maintenance/repair is needed, and where to dispatch the truck for help—this is a huge advantage.

Popular Detroit 60 SERIES Truck Parts
Detroit 60 engine requires many Detroit 60 parts to keep running. The Detroit 60 runs for long time. Some Detroit engine run up to 2,000,000 miles. However, they engine needs routine maintenance. Those Detroit 60 parts are not expensive and are readily available. The Detroit has been running for long time.
Therefore, Detroit 60 parts are available in bulk by OEM and aftermarket sources. Aftermarket Detroit 60 parts are important. The Detroit 60 series aftermarket truck parts make repairs affordable.
Trucks with Detroit 60 engine retain their value better than others. The reason behind this is the availability of the telemarketer Detroit 60 truck parts. Unlike the detroit 60 truck parts the dd15 truck parts are not available in the open market–aftermarket. The other way to get those is through a Detroit dealer.
Detroit 60 Alternators
Alternators are used in trucks to power the electrical system while the engine is running, and to charge the battery for electrical power when the engine is not running.
Alternators take mechanical power from an engine belt to create alternating current. Rectifiers convert this alternating current to unregulated direct current.
Voltage regulators convert this unregulated direct current into the stable, direct current that truck components require.
Rectifiers and voltage regulators are either mounted inside (or attached to the case of) an alternator or they are in a separate module.
If the voltage regulator is separate from the alternator, it is normal practice to replace the rectifiers and voltage regulators when replacing the alternator.
Detroit 60 Mounting Hardware
The mounting bracket, mounting hardware, and alternator pulley are usually reused. If you want these parts replaced, they need to be ordered separately. If your pulley shows signs of age or damage, it should be replaced.
WARNING SIGNS OF A BAD ALTERNATOR
- Warning lights “ALT”.- Warning lights will illuminate while starting the engine, and may persist for a few seconds after starting. Those lights should extinguish after 3~5 seconds.0
- Headlights dim or flickering.
- One head light might be dim for a variety of reasons. If both headlights are dim (plus marker lights, cabin lights, etc.), it is more likely an under-volt situation.
- Other electrical failures.
- Strange noises.
- Difficulty starting. – If a engine makes a “Click-click-click” sound while attempting to crank an engine, stop cranking immediately. The “Click-click-click” sound could be the starter teeth failing to properly engage the flywheel. Continuing to crank without proper flywheel engagement could damage the starter, or flywheel teeth, or both.
- Dead battery

COST to Replace Detroit 60 Alternator
The average cost to replace a detroit 60 alternator is $225. Furthermore, this cost is assuming one would buy a detroit 60 aftermarket alternator. In addition, this cost is without installation.In addition, Installation usually would be an additional 1 to 2 hours labor.
Detroit 60 Turbocharger
In reality, a Turbocharger uses a minor amount of back pressure on the exhaust of an engine. Therefore, to force additional air into an engine’s combustion chambers.
Hence, this additional air allows additional fuel to be injected into the engine’s cylinders, which increases horsepower. Therefore, this additional air also leads to lower emission levels.
COST to replace Detroit 60 turbo
In fact, an OED turbocharger ( also called Detroit 60 turbo) is unique to the Detroit Diesel 60 Series engine. S60 turbo will cost about $1,200. On the other hand, Detroit 60 aftermarket turbo would be $750. Hence, the importance of aftermarket Detroit 60 parts come into play.
In particular , those costs are off course without accounting for installation. Installation of the turbo would be another $700 to 1,100. The cost of Detroit 60 turbo is still a lot cheaper than most other turbos. For example , the C15 turbo would be about $5000.
Detroit 60 Fuel InjectorsFuel Injectors
Furthermore, Fuel injectors squirt fuel directly into the cylinder of an engine. All diesel engines use fuel injection. The Detroit Diesel 60 Series has six injectors (one for each cylinder).
Moreover, the cost of new Detroit 60 fuel injector is about $500. On the other hand, the cost to replace the injector with re-manufactured fuel injector is $300. That represent 50% savings. Moreover, the saving is important since usually when replacing an injector is wise to replace all six to eight injectors.
The reason behind changing all of the Detroit 60 injectors is the labor cost. Further, most of the labor cost is in lifting the valve cover. Therefore, once that is out of the way, replacing one or six is about the same labor. Furthermore,By replacing all of the injectors one can be sure to not have a problem from the injectors for another 200,000 to 300,000 miles.
Finally, there are Detroit 60 injectors kit. Those kits would save you money.
