This replacement fluid reservoir cap is engineered for Renault Clio generations. Designed to replace lost, brittle, or stripped factory caps on either the coolant expansion tank or the windshield washer fluid neck. Reverse-engineered with accurate metric thread profiles and internal sealing gasket seats, it ensures a tight lock to prevent pressure loss or fluid spillage in the engine bay.

Print Recommendations:Material: ABS, ASA, or PP (If used for the coolant expansion tank, ABS, ASA, or Polypropylene is strictly required to survive cooling system pressure and radiant engine heat. For windshield washer necks, PETG is acceptable)Layer height: 0.16mm to 0.12mm optional (Lower layer heights are necessary to achieve crisp, smooth thread tracks for easy hand-tightening)Infill: 80–100% (High density with at least 5-6 perimeter wall lines is crucial to ensure structural airtightness against hot pressurized steam/coolant)Supports: may vary depending on the model orientation and print bed direction.
