What causes a Detroit Diesel Series 60 to overheat?
This can indicate a coolant leak. If there is such a leak, you might also notice lower coolant levels in your engine, but things otherwise appear normal. This can lead to an overheated engine. Operators often find that they experience issues with their EGR system on their 14L Series 60 in particular.
Are there any problems with the Detroit Series 60?
This issue did not affect all pre-2002 Series 60 engines, but it was a problem that occurred and could cause catastrophic engine failure. As with most engines, it’s a good idea to keep an eye on your cooling system. Overheating is the cause of many major issues with diesel engines, so maintaining this system can help with many preventable issues.
What are the cylinders on a Detroit Diesel 12V71?
The first number indicates the series, and the next two digits represent the number of cylinders. All 12V71 engines should start with 712x-xxxx. Of course, if you need any help, just give us a call and we will get the right part to you.
How does a Detroit Diesel engine cool down?
An impeller is pressed on one end of the stainless steel drive shaft. The other end of this shaft has internal threads, and a retaining… The centrifugal-type water pump circulates the engine coolant through the cylinder block, cylinder head, radiator and the oil cooler.
What causes a coolant leak on a Detroit Diesel?
This is particularly true of the EGR cooler. If you’re having a problem with your EGR cooler, you might notice an exhaust leak, especially white exhaust. This can indicate a coolant leak. If there is such a leak, you might also notice lower coolant levels in your engine, but things otherwise appear normal. This can lead to an overheated engine.
What causes a series 60 engine to leak?
In order to lower NOx emissions, later Series 60 engines come equipped with an EGR. This system is often complained about as the cause of engine issues. This is particularly true of the EGR cooler. If you’re having a problem with your EGR cooler, you might notice an exhaust leak, especially white exhaust. This can indicate a coolant leak.
Are there any problems with the Detroit Diesel 14L?
Another common complaint, especially with the 14L, is poor fuel economy. As the engine got bigger and was designed for more horsepower, fuel usage seemed to increase as well. Some argue that this lowering of fuel economy is not due to engine design, but to poor operating practices.
Where is the fuel leak on a Detroit Diesel?
During fuel pressure testing (engine off, 5 minutes at 345 kPa [50 psi]) fuel leakage will be evident at the injector body/plunger spring seat area see Figure 2-2. Factory tests have shown that accumulation of fuel at each injector, approximately a tablespoon may be evident during these tests.
What causes a Detroit Diesel Series 60 bearing to seize?
Bearing problems, particularly spun bearings, are typically caused on older Series 60 by low oil pressure at idle. A spun bearing occurs when there is a lack of lubrication causing overheating. The bearing can eventually seize, creating even more problems.
What should the oil pressure be in Detroit Diesel?
One of the most serious conditions used oil analysis can uncover is the presence of excessive fuel in the lube oil which should not exceed 2.5% maximum of oil volume, reference Detroit Diesel’s Publication 7SE270 “Engine Requirements for Lubricating Oil, Fuel and Filters.”
What’s the PSI on a Detroit 14L truck?
The truck boosts up to 25-28 psi then goes down to 0-5psi then boosts up to 25+ psi again. And it just keeps doing that all day. Back and forth back and forth. When the boost drops you cant hear the turbo, but you can hear this squeaking noise.
Is it a VPOD or a turbo in a Detroit 14L?
If at 700-800, it will be a vpod and possibly a turbo. We change them out all the time. We change both just to be safe. Both if not one, will fail eventually. Pay upfront or pay double with roadside. Jansito Thanks this. 1.Vpod changed. Same thing. 2.Crank, Camshaft sensors changed. 3. All sensors on intake manifold changed.
