Diesel engines are all about maintaining pressure while functioning. This is due to the fact that their combustion process depends on high air pressure. A diesel engine maintains pressure with the help of a number of components. One of these components is the CP3 Pump. This pump creates high pressure and delivers it into the engine. The CP3 pump’s function exposes it to plenty of stress. This is why it’s only natural for this component to wear out over time. When the CP3 pump begins to wear out, its ability to build pressure becomes compromised. And when this happens, the entire engine’s performance can become compromised.
CP3 pump failure in diesel engines is not too hard to diagnose. Most of the times, your engine has trouble starting up. Your engine may have trouble reaching an appropriate RPM. Another common symptom of this problem is excess black smoke. Low pressure in your engine will result in its combustion process becoming inefficient. And as a result of this, your engine begins spewing out “dirty” smoke. Smoke that has particles of unspent fuels in it.
A faulty or broken CP3 pump is a major problem and you should address it as soon as possible. If you suspect that your diesel is suffering from this problem, you should take it to a mechanic who specializes in diesel engines. They can help you get to the bottom of your engine’s problem. And once the problem has been determined, they can help you install a brand new CP3 pump.
Problems like these can end up damaging your engine quite extensively if left unchecked. This is why it is important to have your engine checked regularly. And any problems should be dealt with as quickly as possible.
