It is necessary to replace all the radiator coolant hoses in a Honda NSX because these hoses are responsible for carrying coolant from the radiator to the engine and back, keeping it running at the proper temperature. Over time, these hoses can become brittle, crack, or develop leaks due to exposure to high temperatures, pressure, and chemicals in the coolant.
If a coolant hose fails, it can cause coolant to leak, which can lead to the engine overheating and potentially causing severe damage. Additionally, if the coolant level is low, the engine may not receive enough coolant to keep it running at the proper temperature, which can also cause damage.
Additionally, It is also a good practice to replace all the hoses at once, as they are typically made of similar materials and are exposed to the same conditions. This ensures that all hoses are in good condition, which can help prevent future issues and prolong the life of the engine.
It’s important to check the manufacturer’s recommendations for the replacement interval of the hoses and stick to them, as well as to pay attention to any signs of failure such as leaks, cracks, or swelling.
Hose sets include between 26 and 29 hoses depending on your NSX’s year and model. We also offer a clamp set that features all the necessary clamps for your new hoses; however, it’s not necessary to replace them when you replace your radiator hoses if the clamps are in good shape.
