New Dry Joint manifold installation tips: Priming
P/N HGE5735, HGE4612

As to prevent the internal heat crack caused by the void space inside the manifold, we are here highly recommending that to prime both side of the manifold to the full capacity with water or with 50/50 coolant before mounting the riser or the spacer. This process to be repeated should you remove the manifold for cleaning. The warranty of this part will be voided should you neglect to follow.
