About this item

  • Engine Coolant Water Bypass Steam Vent Gasket
  • Replaces 56390 / 12551933


This is a set of 4 gaskets - enough for one engine. Compatible with all LS engines. Hard to find and always in demand for LS Swappers. These Steam Vent Tube seals are a direct replacement for the leaky, aged factory parts. Or you can carry a spare set just in case; nothing ruins a race weekend like a coolant leak. Be sure to check out our other items for other great LS parts.

No leaks so far and was a direct replacement for the coolant cross over under the intake manifold. Installed in 2001 Silverado 2500hd with 6.0.
