* Corrosion: Different antifreezes have different chemical compositions. Using the wrong type can lead to corrosion of engine components, including the engine block, radiator, water pump, and hoses. This corrosion can cause leaks, reduced efficiency, and ultimately engine failure.
* Clogging: Incorrect antifreeze can react with other substances in the cooling system, leading to the formation of sludge or deposits that clog passages and restrict coolant flow. This overheating can severely damage the engine.
* Seals and Gaskets: Some antifreeze types can attack seals and gaskets, causing leaks and further damage.
* Overheating: If the coolant isn't functioning correctly due to the wrong antifreeze, the engine will overheat, leading to warped cylinder heads, cracked engine blocks, and potentially catastrophic engine failure.
The Dodge Intrepid's cooling system is no different than any other car's in this regard; it requires the correct type and concentration of antifreeze (typically a 50/50 mix of antifreeze and distilled water) as specified in your owner's manual. Using the wrong antifreeze is a recipe for expensive repairs.
