Installation Guide

The installation of the VAICO V20-0738 Coolant Flange follows a straightforward procedure that can be completed by an experienced mechanic or a knowledgeable DIY enthusiast.

1. Preparation: Ensure the cylinder head surface is clean and free from old gasket material. Use a solvent to remove any residue.
2. Positioning: Align the flange with the pre‑drilled holes on the cylinder head, making sure that the bolt pattern matches exactly.
3. Bolt Tightening Sequence: Insert M12 bolts and tighten them in a star pattern to achieve even pressure distribution. Use a torque wrench set to 25 Nm (18 ft‑lb).
4. Leak Check: After tightening, fill the cooling system with distilled water or coolant mixture and run the engine for a few minutes. Inspect the flange area for any signs of leakage.

Maintenance Tips

• Regularly inspect the gasket surface for wear or deformation before each major service interval.
• Avoid over‑tightening bolts, as this can damage the flange material and compromise sealing integrity.
• Use only manufacturer‑approved coolant formulations to prevent corrosion within the cooling system.
