AN4 Stainless Coolant Crossover Steam Vent Kit For LS1 LS2 LS3 LS9 LS7 LS6
Stop unwanted vapor buildup and maintain steady engine temperatures with the AN4 Stainless Coolant Crossover Steam Vent Kit. This direct replacement routes excess coolant steam away from the block before pressure overwhelms the radiator cap. You gain reliable thermal control during track days, towing, or spirited highway cruising. The system works seamlessly with existing GM cooling setups to prevent localized hot spots and protect gasket integrity.

Safe Handling Reminder
Wait until the entire cooling system drops to room temperature before installing these lines. Contact with moving hot fluids creates instant injury risks, and a cool engine guarantees safe positioning during tightening. Your upgraded vent paths keep radiant heat clear of accessory belts and silicone hoses.
