Using the K-Tuned Upper Coolant Housing is straightforward. First, make sure your engine is a K24Z Series engine as it won't work with K24A1 and K24Y Series. Choose the appropriate hose outlet for your radiator hose setup. If you have regular rubber or silicone rad hoses, go for the standard 1.25' rad hose outlet. For upgraded hoses, use the optional 16AN fittings. When installing the optional Filler Neck, place it so that the radiator cap is at the highest point of the cooling system. This will help air pockets escape easily during the coolant bleeding process. Remember, this part is designed to work with an OEM 92 - 00 Honda Civic radiator cap. The housing is meant to be used with our Swivel Neck Thermostat and Water Pump Block off Plate for the best custom and race engine cooling setups. This product doesn't come with a radiator, so you'll need to purchase it separately if you need one. As for maintenance, regularly check the hose connections for any signs of leaks or wear. If you notice any issues, replace the hoses or fittings as needed. Keep the housing clean to ensure optimal performance.
