This coolant pressure relief tube runs between the cylinder heads in the front of LS engines. This tube bolts directly to the cylinder heads and has a quick connect nipple that exits straight out from the left hand side of the engine above the water pump. The nipple is long enough to accept a hose and clamp instead of a factory quick connect fitting.
