Oils from your skin can cause "hot spots" that lead to immediate failure. Use a small amount of dish soap as a lubricant for the rubber seat to ensure it slides into the housing without tearing. Note: This kit is for the internal water pump components. Please verify your exterior housing matches the CN250 design before ordering.
