Why I Believe LS Swap Heater Hoses are a Necessity

As someone who has gone through the process of LS swapping my vehicle, I can confidently say that installing new heater hoses is an absolute necessity. While it may seem like a minor detail, neglecting to replace the heater hoses during an LS swap can lead to major issues in the long run.

Firstly, the stock heater hoses on most vehicles are not designed to handle the increased power and heat output of an LS engine. These hoses are often made of rubber and can easily deteriorate over time, especially when exposed to high temperatures. This can lead to leaks and potential engine damage if not addressed.

Furthermore, LS engines have their water pump inlet and outlet ports in different locations than most stock engines. This means that the existing heater hoses will not fit properly onto the new engine without some serious modifications. Trying to force them or using adapters can also lead to leaks and other complications.

Replacing the heater hoses with ones specifically designed for an LS swap ensures proper fitment and durability. These hoses are made with higher quality materials such as silicone which can withstand high temperatures and maintain their integrity for longer periods of time.

In conclusion, while it may seem like a small detail in the grand scheme
