Coolant Bypass Kits
Coolant bypass kits are designed to improve coolant flow within an engine's cooling system. They typically achieve this by providing an alternative path for coolant circulation, particularly around the thermostat. This can be beneficial in certain situations, such as with performance modifications that generate additional heat, or for engines prone to uneven coolant distribution. When considering a coolant bypass kit, it's important to ensure compatibility with your specific vehicle and understand any potential impact on factory warranties.
