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 Diesel Products, 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 Diesel Products 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.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products 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 Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

Fuel injectors are critical components of your vehicle's engine, responsible for delivering the precise amount of fuel into the combustion chamber. When a fuel injector leaks, it can cause various engine issues, affecting performance and efficiency. Understanding the consequences of a leaking fuel injector can help you address the problem promptly and maintain your vehicle’s optimal performance.
A leaking fuel injector can lead to numerous problems that affect your vehicle's performance, fuel efficiency, and overall engine health. Identifying the symptoms and understanding the implications of a leaking fuel injector is crucial for timely repairs and maintaining your vehicle’s reliability. Here’s what happens when a fuel injector leaks and how it impacts your engine.
-
Decreased Fuel Efficiency
-
One of the immediate effects of a leaking fuel injector is reduced fuel efficiency. Leaked fuel does not contribute to engine power, causing the engine to burn more fuel to achieve the same level of performance, leading to higher fuel consumption.
-
-
Poor Engine Performance
-
Leaking fuel injectors can cause poor engine performance, including rough idling, misfires, and hesitation during acceleration. This happens because the engine does not receive the correct fuel-air mixture for optimal combustion.
-
-
Increased Emissions
-
A leaking fuel injector can result in increased exhaust emissions. Unburned fuel can exit the engine through the exhaust system, leading to higher levels of harmful pollutants being released into the atmosphere.
-
-
Fuel Odor
-
A noticeable fuel odor around your vehicle can be a sign of a leaking fuel injector. This smell occurs because the leaking fuel evaporates and mixes with the air around the engine and exhaust system.
-
-
Potential Engine Damage
-
Continuous fuel leakage can lead to more severe engine damage. Excess fuel can wash away the oil film from the cylinder walls, causing increased friction and wear. Over time, this can result in significant engine damage and expensive repairs.
-
-
Hydro-lock
-
In extreme cases, a leaking fuel injector can cause hydro-lock, where excess fuel enters the combustion chamber and prevents the engine from turning over. This condition can severely damage engine components, including the pistons and connecting rods.
-
In conclusion, a leaking fuel injector can lead to decreased fuel efficiency, poor engine performance, increased emissions, fuel odor, potential engine damage, and even hydro-lock. Recognizing these symptoms early and addressing the issue promptly is essential for maintaining your vehicle’s performance and preventing costly repairs. If you suspect that your fuel injector is leaking, it is crucial to consult with a professional mechanic for a thorough inspection and necessary repairs. Regular maintenance and timely attention to fuel system issues can help keep your engine running smoothly and efficiently.
It delivers the correct amount of fuel into the engine's combustion chamber at the appropriate time, facilitating efficient combustion and smooth engine operation.
Indicators include engine misfires, poor fuel economy, rough idling, and increased exhaust emissions.
Regular inspections during routine maintenance intervals are recommended to ensure optimal performance and prevent potential issues.
Unusual noises may indicate internal issues; it's advisable to have the injector inspected by a qualified technician promptly.
