Using this K - Tuned coolant housing is easy. First, decide if you want the basic setup or the one with the optional filler. When choosing the inlet, pick either standard silicone hoses or - AN fittings based on your needs. If you go for the filler neck option, you can adjust the overflow fitting's direction as you like for a tidy setup. Make sure to regularly check the O - rings at the 16OR outlet and - 12OR filler inlet for any signs of wear. If you notice any leaks, replace the O - rings promptly. Clean the housing periodically to prevent debris build - up, which can affect its performance. Also, when installing, ensure all connections are tight to avoid coolant leakage.
