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 Tamerx Diesel Products 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.
Tamerx 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 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.

A vehicle temperature sensor plays an important role in monitoring engine temperature and helping maintain proper operating conditions. But how often should a temperature sensor be replaced?
When Should You Replace a Temperature Sensor?
Unlike routine maintenance parts, an engine coolant temperature sensor does not have a fixed replacement schedule. Most temperature sensors can last for many years, often throughout the vehicle's lifespan. However, exposure to heat, corrosion, and electrical issues can cause premature failure.
Signs of a Bad Temperature Sensor
Recognizing the symptoms of a faulty temperature sensor can help prevent costly engine repairs. Common warning signs include:
- Check engine light
- illuminating on the dashboard
- Incorrect temperature readings
- on the gauge
- Poor fuel economy
- or increased fuel consumption
- Difficulty starting
- the engine
- Engine overheating
- or irregular cooling fan operation
- Rough idling
- or inconsistent engine operation
Why Timely Temperature Sensor Replacement Matters
A malfunctioning coolant temperature sensor can send inaccurate information to the engine control module, potentially affecting fuel delivery and cooling system operation.
If you notice warning signs, have a qualified mechanic inspect the sensor and related components.
Regular vehicle maintenance and timely temperature sensor replacement can help protect your engine, improve reliability, and prevent unexpected repair expenses.
It uses the temperature signal to adjust engine control strategies and cooling-system operation.
Yes, corrosion or contamination can interfere with the sensor’s thermal response.
It should be checked during overheating diagnostics or when temperature readings fluctuate unexpectedly.
Yes, repeated thermal expansion may degrade the internal sensing element over time.
