K-Tuned has also designed a Filler Neck that relocates the radiator cap to a higher point on the engine itself. The new location is the highest point of the cooling system and allows air pockets to easily escape during the coolant bleeding process. The optional Filler Neck was designed for use with an OEM 92-00 Honda Civic radiator cap. This part will be very helpful on an engine that already has a bad reputation for coolant bleeding.
The K-Tuned Upper Coolant Housing will compliment their Swivel Neck Thermostat and Water Pump Block off Plate. All of these parts allow plenty of options for custom and race engine cooling setups.
Applications: K20A, K20A2, K20A3, K20Z1 cylinder heads
