Fitment And Compatibility

This kit is for the Honda Civic FN2 Type R with the K20Z4 engine. It replaces the listed coolant and vacuum hoses in the FN2 engine bay and includes the clamp kit needed to complete the hose refresh.

• Fits: Honda Civic FN2 Type R K20Z4 with matching hose routing.
• Check first: LHD cars, imported cars, engine-swapped cars and cars with aftermarket radiators, intake manifolds, or modified coolant/vacuum routing should compare the hose layout before ordering.
• Does not fit: EP3 K20A2, DC5, FD2, K-swap cars, FN2 1.8 models or other K-series engines as a complete kit.
• Need EP3 fitment? use the Exoracing Civic EP3 K20A2 13pc silicone hose kit instead.

If you are not sure whether your FN2 hose layout matches, contact us before ordering.

Why Should You Use An Exoracing FN2 Silicone Hose Kit?

Factory Honda rubber hoses can become brittle with age, heat cycles and coolant exposure. On an FN2 Type R, a ruptured coolant hose can cause rapid coolant loss, overheating and avoidable engine damage.

The Exoracing FN2 hose kit upgrades the original rubber hoses to reinforced 4-ply silicone. The kit includes 14 hoses and a full 304 stainless steel worm drive clamp kit, so you can refresh the cooling and vacuum hose system in one job rather than sourcing clamps separately.

The black outer with purple inner layer gives a tidy engine bay finish while adding resistance to heat, UV, water and ageing. It is a practical upgrade for road cars, track cars and restored FN2 K20Z4 engine bays where cooling-system reliability matters.

Exoracing FN2 Silicone Hose Kit Installation Guide:

Before installation, lay out the 14 silicone hoses and match every hose to the original hose it will replace.

1. Make sure the engine is completely cold before opening the cooling system.
2. Safely raise the car if extra access is required and place a drain pan under the radiator drain point.
3. Remove the radiator cap, drain the coolant and dispose of old coolant responsibly.
4. Lay out the 14 silicone hoses and match them against the original hoses before removing everything.
5. Remove one old hose at a time and install the matching Exoracing silicone hose in the same location.
6. Make sure each hose is fully seated on the pipe neck before tightening the supplied 304 stainless clamp.
7. Do not over-tighten clamps, as excessive clamp force can damage silicone hoses.
8. Refill the cooling system with suitable coolant and bleed the system fully.
9. Run the engine up to temperature, check for leaks, then recheck the coolant level once the engine cools.

Installation difficulty: moderate DIY. Professional installation is recommended if you are not confident in draining and bleeding a cooling system.
