The Importance of Ls Oil Cooler Block Off Plate

As a car enthusiast and someone who has worked on numerous LS engine swaps, I can confidently say that the LS oil cooler block off plate is a crucial component that should not be overlooked. This small but mighty plate serves an important purpose in maintaining the health and performance of your LS engine.

First and foremost, the LS oil cooler block off plate is necessary because it prevents any potential leaks from occurring in the oil cooler lines. These lines are prone to wear and tear over time, especially if they are constantly exposed to heat and pressure. If a leak were to occur, it could lead to a loss of oil pressure which can cause serious damage to your engine.

Moreover, installing an LS oil cooler block off plate can also improve the overall cooling efficiency of your engine. The stock oil cooler setup for LS engines is known to create excessive heat which can result in reduced power and potential overheating issues. By blocking off the oil cooler lines, you allow for better circulation of coolant through the radiator, resulting in lower engine temperatures.

Additionally, removing the stock oil cooler setup can increase available space under the hood for other modifications such as turbo or supercharger setups. This is especially important for those looking to maximize performance

My Buying Guide on ‘Ls Oil Cooler Block Off Plate’

As a car enthusiast and owner of an LS engine, I understand the importance of keeping the engine cool to ensure optimal performance and longevity. One crucial component that helps in maintaining the engine’s temperature is the oil cooler. However, in some cases, using an oil cooler may not be necessary, and that’s where an LS oil cooler block off plate comes in. In this buying guide, I will share my experience and provide you with all the necessary information to help you make an informed decision when purchasing an LS oil cooler block off plate.

What is an LS Oil Cooler Block Off Plate?

An LS oil cooler block off plate is a simple yet effective device that blocks off the coolant flow to the oil cooler, thus eliminating it from the cooling system. It is installed between the engine block and the oil filter adapter, effectively sealing off the coolant passages that lead to the oil cooler. This allows for increased oil pressure and better cooling efficiency since all of the coolant goes directly to the radiator.

Why do you need it?

There are several reasons why you might need an LS oil cooler block off plate:

1. Improves Oil Pressure – By blocking off the coolant flow to the oil cooler, all of it goes directly to lubricating critical engine components, resulting in improved oil pressure.

2. Better Cooling Efficiency – Without any obstruction from a secondary cooling system (the oil cooler), all of your radiator’s coolant can focus on keeping your engine at optimal temperature.

3. Cost-Effective – Removing or bypassing your stock oil cooler can be expensive as you might need additional hoses or fittings. An LS oil cooler block off plate is a much cheaper alternative that provides similar results.

Factors to Consider when Purchasing an LS Oil Cooler Block Off Plate

1. Compatibility – The most crucial factor to consider when buying any aftermarket part for your vehicle is compatibility. Make sure that the block-off plate is designed specifically for your LS engine model and year.

2. Material – The material used for manufacturing determines durability and heat resistance. Look for high-quality materials like aluminum or stainless steel that can withstand high temperatures without warping or deteriorating over time.

3. Brand Reputation – When it comes to aftermarket parts, brand reputation matters as it speaks for product quality and reliability. Do some research on different brands before making your purchase.

Installation Process

Installing an LS oil cooler block off plate is relatively simple and can be done by following these steps:

1. Drain Engine Coolant – First, drain all of your engine coolant by removing one of the lower hoses connected to the radiator.

2. Remove Oil Filter Adapter – Next, remove your stock adapter using a wrench or socket set.

3. Install Block Off Plate – Place your new block-off plate on top of where you removed your stock adapter from earlier.

4.Install New Oil Filter Adapter- Screw in your new adapter where you removed your stock one earlier; this will provide proper clearance for mounting a new filter once installed correctly.

5.Refill Engine Coolant- Lastly, refill your engine with fresh coolant and start up your car; check if there are any leaks or issues before taking it out for a test drive.

Conclusion

Investing in an LS oil cooler block off plate can significantly improve both performance and cost-effectiveness for LS owners who don’t need extra cooling capacity from their engines’ stock coolers. Make sure to consider compatibility, material quality, and brand reputation when purchasing one for yourself.
