Why I Believe the LS Oil Cooler Block Off Plate is Necessary
As a car enthusiast and owner of an LS engine, I have encountered many discussions and debates about the necessity of an oil cooler block off plate. Some argue that it is an unnecessary modification, while others swear by its benefits. After doing my own research and experiencing the difference firsthand, I firmly believe that the LS oil cooler block off plate is necessary for optimal engine performance.
Firstly, let’s understand what an oil cooler block off plate does. It essentially blocks off the oil passages that feed into the stock oil cooler and redirects the flow of oil directly to the engine. The stock oil cooler can be prone to failure or leaks, which can result in a loss of oil pressure and potentially damage to the engine. By eliminating this component, you eliminate any potential risks associated with it.
Moreover, removing the stock oil cooler allows for more efficient cooling of the engine’s oil. The stock cooler is not very efficient and can cause higher than desired operating temperatures for the engine. This can lead to reduced performance and even premature wear on internal engine components. With a block off plate, you can install a higher capacity aftermarket oil cooler that is more effective at keeping your engine’s oil at optimal temperatures
My Buying Guide on ‘Ls Oil Cooler Block Off Plate’
As a car enthusiast and someone who loves to work on my own vehicle, I recently came across the need for an LS oil cooler block off plate. After doing some research and going through the process of purchasing one, I wanted to share my experience and provide a buying guide for others who may be in the same situation.
What is an LS Oil Cooler Block Off Plate?
An LS oil cooler block off plate is a metal plate that is used to block off the oil cooler ports on an LS engine. It is typically used when converting from an external oil cooler setup to an internal setup, or when removing the oil cooler completely.
Why do you need an LS Oil Cooler Block Off Plate?
If you are planning on removing your external oil cooler or converting to an internal setup, you will need to block off the ports where the oil cooler lines connect to your engine. Without a block off plate, there will be open ports which can cause leaks and potential damage to your engine.
Factors to Consider
- Compatibility: When looking for an LS oil cooler block off plate, it is important to make sure it is compatible with your specific engine model. Different engines may have different port sizes or locations, so double check before making a purchase.
- Material: Most block off plates are made of aluminum or steel. Both materials are durable and will do the job, but aluminum tends to be lighter in weight.
- Certifications: Look for certifications such as ISO or SAE ratings. This ensures that the product has been tested and meets certain quality standards.
- Brand Reputation: It’s always a good idea to research the brand of the block off plate you are considering purchasing. Look for reviews from other customers and their experiences with the product.
Budget
The price of an LS oil cooler block off plate can vary depending on factors such as material, brand, and certifications. However, they typically range from $20-$50. Keep in mind that spending a little extra money on a high-quality product can save you time and money in the long run by preventing any potential leaks or damage to your engine.
The Buying Process
I personally found it most convenient to purchase my LS oil cooler block off plate online. This allowed me to easily compare prices and read reviews from other customers. However, if you prefer to buy in person, make sure you bring your vehicle information with you so that you can ensure compatibility with your engine model.
Installation
The installation process for an LS oil cooler block off plate is relatively simple and can be done at home with basic tools. However, if you are not comfortable working on your own vehicle, it is best to consult a professional mechanic for assistance.
In Conclusion
If you are planning on removing your external oil cooler or converting to an internal setup on your LS engine, investing in a high-quality oil cooler block off plate is essential. Make sure to consider compatibility, material, certifications, brand reputation, and budget before making a purchase. With proper installation, this small but important component can help prevent any potential leaks or damage to your engine.
