So you've decided to embark on a G body LS swap project - congratulations! This exciting endeavor can result in a powerful and high-performance vehicle, but it's important to ensure that all the components are up to par. When it comes to your cooling system, you need a radiator that can handle the increased demands of the LS engine. That's where a G body LS swap radiator comes in. Specifically designed for the G body platform, this radiator is larger than the stock model and features a high-performance core that can efficiently handle the heat generated by a LS engine. With improved cooling capacity, you can hit the gas with confidence and enjoy all the benefits of your LS swap without any heat-related issues. So, let's dive into the world of G body LS swap radiators and find the one that's right for your project.
If you're new to the world of G body LS swap radiators, it can be overwhelming to navigate all the options available. You may find yourself wondering: what type of core should I go for? What size radiator do I need? How important is brand reputation?
To help answer these questions and make the decision process easier, let's take a closer look at some key factors to consider when choosing a G body LS swap radiator.
First and foremost, the core type is crucial in determining the cooling efficiency of a radiator. The most common types are aluminum and copper/brass. Aluminum cores are lightweight, have better heat transfer capabilities, and are less prone to corrosion. On the other hand, copper/brass cores have higher durability and are easier to repair. When it comes to G body LS swap radiators, either type can work well, but keep in mind that aluminum cores are more popular due to their performance benefits.
Next, the size of your radiator should be carefully considered. It's important to select a larger radiator than the stock model to accommodate the increased demands of an LS engine. This will ensure that your engine stays cool even under extreme conditions. Additionally, make sure to measure the space available in your G body and choose a size that will fit without any modifications. Keep in mind that larger radiators may require additional brackets or mounts for proper installation.

G body LS Swap Radiator FAQs
Do I need a radiator that has been thermal transfer pressure tested?
Yes, it is recommended to choose a radiator that has undergone thermal transfer pressure testing. This ensures that the radiator can withstand high temperatures and pressures without leaking or malfunctioning. It also guarantees that the radiator will efficiently transfer heat away from the engine for optimal cooling performance. Furthermore, make sure to check the manufacturer's specifications for their testing process and standards to ensure the highest quality radiator for your vehicle.
Can I use a regular car radiator for my LS swap?
Yes, you can use a regular car radiator for an LS swap. However, it is important to choose one with the correct core size and fittings for your specific LS engine model. Additionally, make sure that the radiator has sufficient cooling capacity for your engine's horsepower and torque output. Using a high-quality radiator specifically designed for LS swaps, such as the Cold Case radiators, can provide better performance and durability in the long run.
What is TIG welding and why is it important for radiators?
TIG (Tungsten Inert Gas) welding is a precise and high-quality welding process that uses a non-consumable tungsten electrode to create a weld. This method produces clean and strong welds without adding any filler material, resulting in a very clean and strong joint. For radiators, TIG welding is crucial as it ensures the radiator tanks and core are securely bonded together, preventing any leaks or malfunctions that could lead to engine damage.
Can I install an oversized radiator for better cooling performance?
Installing an oversized radiator can provide better cooling performance, but it is important to consider the fitment and compatibility with your vehicle. Oversized radiators may require modifications to your vehicle's mounting brackets or fan shroud, and may also affect airflow through the engine bay. It is recommended to consult with a professional mechanic or radiator specialist before installing an oversized radiator for optimal results.
How often should I flush and refill my radiator?
It is recommended to flush and refill your radiator every 2-3 years or every 30,000-50,000 miles. Over time, contaminants can build up in the cooling system and affect its effectiveness. Flushing the system removes these contaminants and refilling with fresh coolant ensures proper cooling performance.
Conclusion
When performing an engine swap, the LS engine stands out as an excellent choice, offering both beauty and the desired power. Opt for a radiator with increased surface area and superior thermal transfer capabilities. Featuring pressure testing, enhanced cooling surface per square inch, corrugated fins, and an electric fan setup, it efficiently replaces the original cooling fan. With the new radiator positioned and the upper hose on the right side, rerouting the upper hose is unnecessary. Stay cool and get your G body LS radiator today!
