Using the K-Tuned Upper Coolant Housing is straightforward. First, make sure your engine is either a K20Z3 or has K24 heads as it won't work with K24Z, K24Y Series Engines, or K24A1. When installing, choose the hose outlet that fits your radiator hose setup. You can go for the standard 1.25' outlet for regular rubber or silicone hoses. If you're using the optional Filler Neck, install it to relocate the radiator cap to a higher point on the engine. This will help air pockets escape during coolant bleeding. Just remember, the rad cap isn't included, so you'll need to get one that's compatible, like an OEM 92 - 00 Honda Civic radiator cap. As for maintenance, regularly check the hose connections for any signs of leaks or wear. Also, keep an eye on the coolant level. When it comes to turbos, the housing may have fitment issues depending on the size of the turbo and manifold. And if you have a Jackson Racing Supercharger with a K20 engine, you might face fitment problems too. So, always double - check before installation.
