What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The Detroit DD15 engine is known for its power, efficiency, and durability. A key component that keeps this engine running smoothly is the Engine Oil Pump OEM 4721805601. Though often overlooked, this pump plays one of the most critical roles in the engine—circulating oil to protect moving parts from friction, heat, and wear.
Core Role
The main role of the DD15 engine oil pump is to maintain proper oil pressure and ensure continuous lubrication throughout the engine. It draws oil from the oil pan and distributes it through internal passages to key components such as bearings, pistons, camshafts, and turbochargers.
Key Functions
- Lubrication
- Creates a steady flow of oil that coats internal parts, minimizing friction and metal-to-metal contact.
- Cooling
- Carries heat away from engine components to help prevent overheating and maintain optimal operating temperatures.
- Cleaning & Protection
- Helps suspend and remove contaminants from critical areas, working in conjunction with the oil filter to keep the system clean.
- Pressure Regulation
- Maintains consistent oil pressure to ensure stable engine performance under all conditions.
Without a properly functioning oil pump, the DD15 engine could suffer from rapid wear, overheating, and even catastrophic failure. The OEM 4721805601 oil pump ensures that every moving part is protected, extending the engine’s life and keeping it operating efficiently in demanding applications.
The engine oil pump is one of the most critical components in your vehicle’s lubrication system. It circulates oil throughout the engine to reduce friction, cool components, and prevent wear. When the oil pump starts to fail, the consequences can be severe — even leading to complete engine failure if not addressed quickly.
Common Symptoms of a Bad Oil Pump
Before diagnosing, watch for these key warning signs:
- Low oil pressure warning light
- on the dashboard
- Tapping or knocking noises
- from inside the engine
- Overheating
- caused by poor lubrication
- Oil pressure gauge fluctuations
- while driving
- Increased engine wear
- or metal shavings in the oil
How to Diagnose a Failing Oil Pump
Follow these steps to confirm whether your oil pump is the problem:
- Check the oil level and condition.
- Low or dirty oil can mimic pump failure symptoms.
- Inspect the oil filter.
- A clogged filter can restrict oil flow and lower pressure.
- Use a mechanical oil pressure gauge
- to test actual pressure readings. If pressure remains low, the pump is likely weak or damaged.
- Listen for internal noises.
- A failing pump often causes loud ticking or knocking sounds from lack of lubrication.
Diagnosing a bad engine oil pump requires attention to warning lights, oil pressure readings, and engine noise. If you suspect pump failure, stop driving immediately — running the engine without proper oil pressure can cause catastrophic damage. Have the system inspected and serviced as soon as possible.
