Drive On Diesel provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.
Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".
If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible.

As is the case for the majority of the diesel products sold on Drive On Diesel, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Drive On Diesel will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
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 Drive On Diesel, 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 Cummins ISL 8.9L engine relies on a secure and well-sealed cylinder head, which is where the OEM 4903481 head bolts come into play. These head bolts are responsible for keeping the cylinder head tightly fastened to the engine block, ensuring a proper seal to maintain combustion and prevent leaks.
Head bolts play a crucial role in engine integrity by distributing the clamping force across the cylinder head. This prevents engine damage and allows your Cummins ISL 8.9L to operate smoothly over the years.
Here’s how Cummins ISL head bolts function:
- Provide even distribution
- of clamping force across the cylinder head.
- Maintain a strong seal
- between the engine block and cylinder head.
- Prevent engine leaks
- which could lead to overheating or damage.
- Support high combustion pressures
- ensuring efficient engine operation.
Proper installation and periodic inspection of these head bolts are key to ensuring engine longevity. Over time, head bolts can stretch or become weakened, which may require replacement to prevent issues like head gasket failure.
If you're working on a Cummins ISL 8.9L engine, consider checking the condition of your OEM 4903481 head bolts to keep your engine running at its best.
Head bolts are crucial for securing the engine's cylinder head to the engine block. When these bolts begin to fail or become loose, it can lead to serious engine problems. Recognizing the signs early can help prevent costly repairs.
Common Signs of Failing or Loose Head Bolts:
- Coolant Leaks
- If you notice coolant leaking from the engine, it could be due to the head bolts losing their grip, allowing the head gasket to fail.
- Overheating
- Loose head bolts can cause a poor seal, leading to engine overheating as coolant fails to circulate properly.
- Misfiring Engine
- A poor seal between the head and block can result in cylinder misfires, causing the engine to run rough.
- Exhaust Smoke
- White or blue smoke from the exhaust can indicate a problem with head bolts, as the failing seal allows fluids to enter the combustion chamber.
If you suspect head bolt issues, it’s crucial to address them immediately. Loose bolts can lead to severe engine damage if left unattended. Regular inspection of engine components, especially during routine maintenance, can help catch issues before they escalate.
