What happens when using incompatible long-life anti-freeze?

When using incompatible long-life anti-freeze, it can cause clogging within the cooling system. This happens because different types of antifreeze contain various additives and corrosion inhibitors that may not interact well with each other, leading to the formation of sludge, particulate matter, or other debris. This buildup can obstruct coolant passages, radiators, and heater cores, ultimately diminishing the efficiency of the cooling system and potentially leading to overheating problems.

Furthermore, the incompatibility can result in chemical reactions that degrade the properties of the coolant, causing it to lose its protective abilities against corrosion and cavitation. Therefore, utilizing anti-freeze specifically formulated for the vehicle's system is critical in maintaining the integrity and functionality of the entire cooling system.
