LS Swap Radiator with Fans: A Comprehensive Guide

The LS engine is a popular choice for engine swaps due to its power, reliability, and affordability. When performing an LS swap, one of the most important considerations is the cooling system. The stock radiator and fans may not be adequate for the increased heat generated by the LS engine, especially in high-performance applications. Upgrading to a larger radiator and more powerful fans can help ensure that your engine runs cool and performs at its best.

Choosing the Right Radiator

The first step in upgrading your cooling system is choosing the right radiator. There are many different radiators available on the market, so it's important to select one that is specifically designed for your application. Consider the following factors when choosing a radiator:

  • Engine size: The size of your engine will determine the amount of heat that needs to be dissipated. A larger engine will require a larger radiator.
  • Power level: The power level of your engine will also affect the amount of heat that needs to be dissipated. A high-performance engine will require a larger radiator than a stock engine.
  • Vehicle application: The type of vehicle you're installing the LS engine in will also affect your radiator choice. Some vehicles have more space for a radiator than others.
  • Budget: Radiators can range in price from a few hundred dollars to over a thousand dollars. Set a budget before you start shopping so you can narrow down your options.

Choosing the Right Fans

Once you've chosen a radiator, you need to select fans that will provide adequate airflow. There are two main types of fans to choose from: mechanical fans and electric fans. Mechanical fans are driven by the engine, while electric fans are powered by the battery. Electric fans are typically more efficient than mechanical fans, but they can also be more expensive.

When choosing fans, consider the following factors:

  • Airflow: The airflow rating of the fans is measured in cubic feet per minute (CFM). The higher the CFM rating, the more air the fans will move.
  • Noise level: Some fans are louder than others. If you're concerned about noise, choose a fan with a lower noise level.
  • Price: Fans can range in price from a few hundred dollars to over a thousand dollars. Set a budget before you start shopping so you can narrow down your options.

Installing the Radiator and Fans

Once you've chosen a radiator and fans, you need to install them. The installation process will vary depending on the specific radiator and fans you've chosen, but some general steps are as follows:

  • Remove the old radiator and fans.
  • Install the new radiator.
  • Install the new fans.
  • Connect the fans to the power source.
  • Fill the cooling system with coolant.

Testing the Cooling System

Once you've installed the new radiator and fans, you need to test the cooling system to make sure it's working properly. To do this, start the engine and let it run for a few minutes. Check the temperature gauge to make sure the engine is running at the proper temperature. You can also use a laser thermometer to measure the temperature of the radiator hoses. The hoses should be hot, but not too hot to touch.

Maintaining the Cooling System

Once you've installed a new radiator and fans, it's important to maintain the cooling system to keep it running properly. This includes the following:

  • Checking the coolant level regularly.
  • Flushing the cooling system every 2-3 years.
  • Replacing the radiator hoses every 5-6 years.
  • Inspecting the radiator and fans for damage or leaks.
By following these tips, you can ensure that your LS swap radiator and fans are working properly and that your engine is running cool and performing at its best.
