We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Drive On Diesel only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.
The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
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. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.
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 customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Drive On Diesel offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Drive On Diesel core charge presented to you online today with your item is representative of the most common core charge.

The Mitsubishi Fuso S4S Turbo Assembly (OEM 310-9695) is far more than just an exhaust component—it plays a crucial role in how the engine manages airflow and utilizes exhaust energy. Designed for 2011–2015 S4S engine applications, this turbo assembly helps maintain the balance between the intake and exhaust systems, allowing the engine to operate efficiently across a wide range of conditions.
While many engine parts perform a single task, the turbo assembly influences several systems at once, making it one of the most important components under the hood.
Why is the Mitsubishi Fuso S4S Turbo Assembly important?
- Transforms exhaust energy into useful airflow
- Instead of allowing exhaust gases to leave the engine unused, the turbo captures that energy and uses it to compress incoming air.
- Supports efficient combustion
- A steady supply of compressed air helps create the ideal environment for fuel combustion inside the cylinders.
- Maintains airflow during changing workloads
- Whether the engine is operating under light or demanding conditions, the turbo helps deliver the airflow needed to match engine requirements.
- Promotes balanced engine operation
- By coordinating the movement of air entering and exhaust leaving the engine, the turbo helps keep multiple systems working together smoothly.
- Assists emissions-related processes
- Proper airflow is essential for supporting combustion quality and the operation of emissions-control components.
- Contributes to long-term engine reliability
- Consistent airflow helps reduce unnecessary stress on other engine components and supports stable operation over time.
Think of the Mitsubishi Fuso 310-9695 Turbo Assembly as the engine's airflow engine room. It takes energy that would normally be wasted through the exhaust and puts it to work, helping the engine breathe properly, maintain smooth operation, and support the overall health of the intake and exhaust systems.
While you may still be able to drive with a failing turbo assembly, it’s generally not recommended. A turbocharger plays a critical role in engine airflow, and when it begins to fail, it can create problems that affect both drivability and long-term engine health.
The severity of the risk depends on the type of turbo failure. Some issues may only cause reduced efficiency, while others can lead to significant engine damage if ignored.
Here’s what can happen if you continue driving:
- Reduced engine response
- A failing turbo may struggle to deliver the airflow needed for proper combustion, resulting in sluggish acceleration and decreased responsiveness.
- Excessive exhaust smoke
- Damaged turbo seals can allow oil to enter the exhaust system, producing blue, black, or white smoke from the tailpipe.
- Increased oil consumption
- Internal turbo wear can cause oil leaks, forcing the engine to use more oil than normal and increasing the risk of lubrication issues.
- Unusual noises from the turbocharger
- Whining, grinding, or rattling sounds may indicate worn bearings or damaged internal components that can worsen over time.
- Potential engine damage
- In severe cases, a failed turbo can send metal debris into the intake system or allow excessive oil into the engine, leading to costly repairs.
- Check engine lights and fault codes
- The engine management system may detect abnormal boost levels and trigger warning lights or place the vehicle into a reduced-power mode.
If your turbo assembly is showing signs of failure, driving a short distance to a repair facility is usually acceptable. However, prolonged operation can increase the likelihood of secondary engine damage and significantly increase repair costs. Having the turbo inspected and repaired as soon as possible is the safest approach.
A complete assembly typically includes the turbine housing, compressor housing, center rotating assembly, shaft, bearings, and associated mounting components.
