Why Do You Need A Honda Civic Ep3 Silicone Hose Kit?

If you own a Honda Civic Ep3, consider installing one of our Exoracing Ep3 silicone hose kits. These kits are specially designed to replace the OEM Honda coolant hose system that can often become brittle and fail over time.

Honda uses rubber for its cooling and vacuum system from the factory, mainly because of the cost of manufacture. However, this is not the best option, as rubber will deteriorate and fail over time, requiring replacement hoses.

This is where our 4-ply Ep3 Silicone hose kits come in. Due to the properties of silicone, the hose kits will more than likely outlast the car!

Our high-quality silicone Ep3 hose kit is resistant to cracking, bursting, and discolouration, making them a reliable option for your vehicle.

What sets our Ep3 silicone hose kits apart is their durability and strength. Each kit includes 13 reinforced high-grade silicone hoses capable of withstanding temperatures up to 500°F/260°C degrees without distorting.

This is significantly more than your cooling system will ever produce, so you can be confident that our hoses are up to the task.

Style is also important, and our silicone hose kits are available in various colours to ensure they complement any engine bay. Whether you're looking for a sleek black or a vibrant blue, we've got you covered. 

If you want to complete your build, browse our selection of silicone joiners and other related products in our silicone hose kit category.

To conclude, our Exoracing Ep3 silicone hose kit is an excellent investment for any Honda owner who wants to ensure the longevity and reliability of their vehicle. With our high-quality materials and superior design, you can rest assured that you're getting the best possible product for your money.

Exoracing Ep3 Silicone Hose Kit Installation Guide:

If you are unsure how to install our Exoracing Ep3 silicone hose kit, please follow our step-by-step guide to ensure the kit is installed correctly. If you aren't sure about anything in this guide, please get in touch with a professional mechanic to install the kit for you.

  1. Firstly you will want to ensure the engine is cool to the touch to reduce the risk of burns from hot coolant.
  2. Next, jack the car up using safety precautions such as axle stands, and drain the old coolant using the drain bung on the bottom of the radiator.
  3. Now start removing the old hoses, matching them to a hose in the kit, and replacing them with the high-grade Exoracing Silicon hose option.
  4. To prevent leaks, do this for all 13 hoses in the kit, ensuring they are fully seated, and the clamps are tightened correctly.
  5. Put the drain plug back in the radiator and fill the system with coolant, making sure to bleed it correctly so no air is left in the system. As a side note, we recommend using Genuine Honda coolant here, as it is the best option for 99% of applications.
  6. You're all done! Enjoy your new Exoracing Ep3 silicone hose kit, and tag us in any photos you have on social media!

If you need to clean the silicone hoses after they get covered in dirt and debris, you can use almost any engine bay degreaser or glass cleaner, as the silicone is resistant to both chemicals.

We have now written a full guide detailing how to install the hoses from start to finish, so click the link below to head over to this guide. Although in the video, we installed a Honda D-Series hose kit, the same process would apply to any hose kit you are trying to install:
