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 Tamerx, 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). Tamerx 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 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.

Damaged or deteriorating hoses in a Turbo Hose Kit can allow pressurized air to escape between the turbocharger, intercooler, and engine intake. Cracks, loose connections, and worn hose material can lead to noticeable airflow and boost-related problems that should be addressed promptly.
- Loss of engine power: A leaking turbo hose can reduce boost pressure and make acceleration feel weaker than normal.
- Hissing or whistling noises: Escaping pressurized air may produce unusual sounds, especially during acceleration.
- Visible cracks or splits: Heat, pressure, and age can cause turbo hoses to develop cracks, tears, or soft areas.
- Check engine light: Significant boost leaks may trigger airflow, intake pressure, or turbo-related diagnostic trouble codes.
- Excessive exhaust smoke: Incorrect air-to-fuel balance caused by an air leak may contribute to increased smoke.
- Reduced fuel efficiency: The engine may operate less efficiently when the intake system cannot maintain the expected boost pressure.
- Loose or oily connections: Oil residue around hose connections, damaged clamps, or hoses that repeatedly loosen can indicate a developing leak.
Identifying Turbo Hose Kit problems early can help prevent boost leaks from becoming more serious. Inspecting the hoses, clamps, fittings, and surrounding intake connections when symptoms appear helps maintain proper airflow and dependable turbo system operation.
A boost leak may produce a hissing or rushing-air sound, especially under load. Technicians can also inspect the hoses and perform a charge-air system pressure test to locate leaks.
Yes. A split, loose, or poorly sealed turbo hose can allow pressurized air to escape before reaching the engine. This can result in lower-than-expected boost pressure.
Heat, oil exposure, age, and prolonged operating conditions can cause hose material to soften or swell. A deteriorated hose should be inspected for loss of strength or sealing ability.
Excessive oil exposure can deteriorate some hose materials over time. If significant oil is found inside or around the hoses, the source of the oil should also be investigated.
