Fitment And Compatibility

This kit has confirmed fitment for UK/RHD Honda Civic EP3 Type R K20A2 models. It is not suitable for the Honda Integra DC5 or the Honda Civic FN2 as a complete kit.

• Confirmed: UK/RHD Honda Civic EP3 Type R with K20A2 engine and standard hose routing.
• Check before ordering: compare the 13 hose locations and OE references below if your car is LHD, imported, engine-swapped, or has aftermarket cooling/vacuum routing.
• Need FN2 fitment? use the Exoracing Civic FN2 K20Z4 14pc silicone hose kit instead.

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

Why Should You Use An Exoracing EP3 Silicone Hose Kit?

Factory Honda rubber coolant and vacuum hoses become brittle with age, heat cycles and engine bay contamination. On an EP3 Type R, a split coolant hose can quickly cause overheating, coolant loss and time off the road.

The Exoracing EP3 hose kit upgrades the original rubber hoses to reinforced 4-ply silicone. The kit is supplied with 13 hoses and a full 304 stainless steel worm drive clamp kit, so you can replace the listed hoses in one cooling-system refresh instead of hunting for individual clamps during installation.

The black outer with purple inner layer keeps the engine bay tidy while adding long-term resistance to heat, water, UV and ageing. It is a practical upgrade for road cars, track cars and restored EP3 K20A2 engine bays where reliability matters.

Exoracing EP3 Silicone Hose Kit Installation Guide:

Before installation, match every silicone hose in the kit to the hose it will replace.

1. Make sure the engine is completely cold before opening the cooling system.
2. Safely raise the car if 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 13 silicone hoses and match them against the original hoses using the location table and diagram.
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.
