In this buying guide, I will share my knowledge and experience with purchasing and installing an LS heater core bypass.

What is an LS Heater Core Bypass?

An LS heater core bypass is a modification that diverts the flow of coolant away from the heater core, effectively disabling it. This allows for better engine cooling performance and eliminates any potential issues caused by a faulty heater core.

Why should you consider an LS Heater Core Bypass?

If you live in a warmer climate or do not frequently use your vehicle’s heating system, an LS heater core bypass can be a practical and cost-effective solution to avoid potential issues with your car’s heating system. Additionally, it can improve engine cooling performance, which is crucial for high-performance vehicles.

Things to Consider before Buying

Prior to purchasing an LS heater core bypass, there are a few things that you should keep in mind:

  • Compatibility: Make sure that the bypass kit you are considering is compatible with your specific LS engine model. There are different variations of the LS engine, so it is crucial to choose one that will work for your vehicle.
  • Budget: The price of an LS heater core bypass kit can range from $30 to $100 depending on the brand and quality. Set a budget beforehand to narrow down your options.
  • Quality: It is essential to invest in a high-quality kit as it will ensure durability and proper functionality. Cheaper options may lead to future problems or require frequent replacements.
  • User Reviews: Take some time to read reviews from other buyers who have used the same kit. This will give you valuable insight into its performance and reliability.

The Installation Process

The installation process for an LS heater core bypass may vary slightly depending on the specific kit you purchase. However, most kits come with detailed instructions that make installation relatively straightforward for anyone with basic mechanical skills. It typically involves draining coolant from the system, removing certain hoses or pipes connected to the heater core, and then installing the bypass tubes provided in the kit.

Finding Quality Products

To ensure quality products and a seamless installation process, I recommend purchasing from reputable brands such as Mishimoto or ICT Billet. These companies specialize in aftermarket parts for cars and have been trusted by many car enthusiasts for their quality products.

Conclusion

An LS heater core bypass can be an excellent investment for those looking to improve their vehicle’s cooling performance or avoid potential issues with their heating system altogether.
