Why a Block Heater for My 7.3 Diesel is a Necessity

As an owner of a 7.3 diesel engine, I can confidently say that investing in a block heater has been one of the best decisions I’ve made for my vehicle. This small but powerful device has proven to be crucial, especially during the colder months. Here are a few reasons why I believe a block heater is a necessary addition to any 7.3 diesel engine.

First and foremost, starting a diesel engine in cold weather can be quite challenging. The thick motor oil and other fluids in the engine tend to become thicker, making it harder for the engine to turn over. This results in increased wear and tear on the starter motor and battery, ultimately shortening their lifespan. However, with a block heater installed, the engine’s temperature is raised, making it easier to start and reducing stress on these crucial components.

Moreover, a block heater helps improve fuel efficiency by warming up the engine before starting it. A cold engine takes longer to reach its optimal operating temperature, resulting in poor fuel combustion and reduced efficiency. By using a block heater, you can reduce warm-up time significantly and save on fuel costs.

Additionally, using a block heater can also

My Buying Guide on Block Heater For 7.3 Diesel

I have owned my 7.3 diesel truck for years now and one of the best investments I have made is installing a block heater. Living in a colder climate, starting my truck in the winter used to be a struggle, but with the block heater, it has become much easier. If you are considering purchasing a block heater for your 7.3 diesel, here is my buying guide to help you make an informed decision.

Why Do You Need a Block Heater?

If you live in an area where the temperature drops below freezing, then a block heater is a must-have for your 7.3 diesel truck. The cold weather can cause the engine oil to thicken, making it harder for your truck to start. A block heater warms up the engine and keeps it at an optimal temperature, making it easier to start your truck even on the coldest days.

Types of Block Heaters

There are two types of block heaters available for 7.3 diesel engines – electric and coolant heaters.

  • Electric Block Heaters: These heaters use an electric element that heats up the engine oil directly. They are easy to install and provide quick heat-up times.
  • Coolant Heaters: These heaters circulate heated coolant through the engine, keeping it warm. They take longer to heat up but provide more consistent warmth throughout the engine.

Consider Your Needs

Before buying a block heater, consider your specific needs and preferences.

  • Cold Weather: If you live in an extremely cold climate, an electric block heater would be more suitable as it provides quicker heat-up times.
  • Budget: Electric block heaters are typically more expensive than coolant heaters, so if you are on a budget, consider opting for a coolant heater instead.
  • Frequent Traveler: If you often travel with your truck or use it for work purposes, an electric block heater would be more convenient as you can easily plug it into any outlet.

Durability and Compatibility

When purchasing a block heater, make sure to check its compatibility with your 7.3 diesel engine model. Also, look for one that is made from durable materials such as stainless steel or heavy-duty plastic to ensure longevity.

Ease of Installation

If you plan on installing the block heater yourself, make sure to choose one that comes with clear instructions and all necessary hardware included. Some models may require professional installation which will add to the overall cost.

In Conclusion

A block heater is essential for any 7.3 diesel owner living in colder climates. It not only makes starting your truck easier but also helps reduce wear and tear on your engine during cold starts. Consider these important factors before purchasing a block heater and choose one that best fits your needs and budget.
