Symptoms Of A Failing ACERT Oil Pump

There are three main symptoms of a failing oil pump on your C15 ACERT diesel engine. These include, but are not limited to:

Low Oil Pressure 

Low oil pressure can be caused by a variety of problems, including a blocked, seized, or damaged oil pump.

Higher Operating Temperatures 

When an engine doesn’t get enough oil to lubricate the necessary moving parts, operating temperatures rise due to the metal-on-metal contact. 

Strange Or Unusual Noises Coming From The Engine

A defective pump can prevent oil from reaching critical components in the C15 ACERT and therefore not only increasing damage but also noise.

Keep in mind that the symptoms noted above are only the most common, but not the only ones. An experienced shop can help determine and repair issues related to a failing oil pump on your engine.

Common Causes Of A Failing Oil Pump

Several reasons could cause an oil pump to fail. For example, contaminants as small as a single grain of sand could have entered the system during installation. All components and surfaces must be kept clean when installing a new oil pump on your C15 ACERT.

A poor install can also put unwanted stress on the housing, causing it to fail much earlier than normal. Something as simple as not adding the correct shims can cause the gears to rub against the pump housing, yielding significant damage down the road.

Replacing the oil pump will not always solve the problem. Low oil pressure could still be present even after swapping out the pump with a new one. Issues including a faulty oil pressure gauge, worn bearings, plugged filters, etc can still give a low oil pressure reading. Have a look at our low oil pressure article here for more information!
