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 Diesel Products 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 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 coolant temperature sensor is a crucial component in your vehicle's engine management system, responsible for monitoring the engine's temperature and relaying this information to the engine control unit (ECU). A failing coolant temp sensor can lead to various engine performance issues and potential overheating. Understanding what causes a coolant temp sensor to fail can help you take preventive measures to maintain your engine’s health and efficiency.

Common Causes of Coolant Temp Sensor Failure

Several factors can contribute to the failure of a coolant temperature sensor. Here are some of the most common causes:

Corrosion
- Exposure to moisture and coolant can cause the sensor to corrode over time. Corrosion can interfere with the sensor’s ability to accurately measure temperature, leading to incorrect readings.
Wiring Issues
- Faulty or damaged wiring and connectors can disrupt the electrical signal between the sensor and the ECU. This can result in intermittent or complete failure of the sensor.
Contaminants
- Dirt, oil, and other contaminants can accumulate on the sensor, affecting its ability to accurately measure the engine’s temperature. This buildup can cause the sensor to give false readings or fail completely.
Wear and Tear
- Over time, the sensor can wear out due to constant exposure to high temperatures and the harsh environment of the engine bay. This natural wear and tear can lead to sensor failure.
Coolant Leaks
- Leaks in the cooling system can cause air pockets to form around the sensor, leading to inaccurate temperature readings. Consistent exposure to leaking coolant can also damage the sensor.
Thermal Stress
- Rapid changes in temperature can cause thermal stress, leading to cracks or other damage to the sensor. This is particularly common in engines that frequently experience extreme temperature fluctuations.
Manufacturing Defects
- Occasionally, a coolant temp sensor may fail prematurely due to manufacturing defects. These defects can include issues with the materials used or errors in the assembly process.
Electrical Interference
- Interference from other electrical components or systems in the vehicle can disrupt the signal from the coolant temp sensor, leading to faulty readings or sensor failure.

Symptoms of a Failing Coolant Temp Sensor

Recognizing the symptoms of a failing coolant temp sensor can help you address the issue before it leads to more severe engine problems. Look out for these signs:

Check Engine Light
- One of the most common symptoms is the illumination of the check engine light. Diagnostic trouble codes related to the cooling system can help identify the sensor as the problem.
Poor Fuel Economy
- A malfunctioning sensor can cause the ECU to miscalculate the air-fuel mixture, leading to decreased fuel efficiency.
Engine Overheating
- If the sensor fails to provide accurate temperature readings, the ECU may not activate the cooling fans or adjust the fuel mixture properly, leading to engine overheating.
Rough Idling
- Inaccurate temperature readings can cause the engine to run rich or lean, resulting in rough idling or stalling.
Hard Starting
- A faulty sensor can make it difficult to start the engine, especially in extreme temperatures, as the ECU relies on accurate temperature data to set the fuel mixture.
Erratic Temperature Readings
- If the temperature gauge on your dashboard shows erratic or inconsistent readings, it could be a sign of a failing coolant temp sensor.

Preventive Measures

To prolong the life of your coolant temp sensor and ensure your engine runs efficiently, consider these maintenance tips:

Regular Inspections
- Periodically inspect the coolant temp sensor and its wiring for signs of damage or corrosion. Early detection can prevent more serious issues.
Use High-Quality Coolant
- Always use high-quality coolant to reduce the risk of contaminants and corrosion in the cooling system.
Maintain the Cooling Syste
- Keep your cooling system in good condition by regularly checking for leaks and ensuring proper coolant levels.
Clean the Sensor
- If accessible, clean the sensor to remove any dirt or debris that might affect its performance.
Follow Manufacturer Recommendations
- Adhere to the manufacturer’s recommended maintenance schedule for replacing the coolant temp sensor and other related components.

Understanding the common causes of coolant temp sensor failure can help you take preventive measures to maintain your engine’s performance and reliability. Regular inspections, proper maintenance of the cooling system, and using high-quality coolant are essential practices to ensure the longevity of your coolant temp sensor.

TAMERX DIESEL REVIEWS

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
