Using this K-Tuned Swivel Lower Water Neck is straightforward. First, remove the plastic OEM housing from your water pump. Then, bolt the new housing directly onto the water pump housing. You can rotate the neck 360 degrees to position the rad outlet in the best direction for your setup. If you need to connect additional coolant lines, use the 8AN accessory port and plug it when not in use. Remember, this housing is designed for race setups and cannot house a thermostat. For maintenance, use the drain plug at the bottom of the housing to empty the coolant when needed. Regularly check the O-Ring seal for any signs of wear and tear to ensure a proper seal.
