Using the K-Tuned Upper Coolant Housing is easy. First, make sure your engine is a K24Z series engine as it won't work with K24A1 and K24Y series engines. When installing, you can adjust the hose outlet to about 15 degrees to fit your setup better. If you choose to use the optional Filler Neck, it can help with coolant bleeding. Just make sure to use an OEM 92 - 00 Honda Civic radiator cap with it. Be aware that if you have a turbo, there might be fitment issues depending on the size of the turbo and manifold. As for maintenance, regularly check the O - ring and hose connections for any signs of wear or leaks. Keep the housing clean to ensure optimal performance. And remember, the rad cap is not included, so you'll need to provide your own.
