What coolant to use for 1999 Lincoln town car?

A 1999 Lincoln Town Car requires a 50/50 mix of ethylene glycol-based coolant and distilled water. It's crucial to use the correct type of coolant to avoid damaging the engine. Ford recommends a conventional green coolant, but you can also use a Dex-Cool compatible coolant (though a dedicated Dex-Cool coolant isn't strictly necessary). Do not mix different types of coolant.

Before adding coolant, check your owner's manual for the specific recommendations from Lincoln. The manual will specify the type of coolant and the correct mixing ratio. If you can't find your owner's manual, consult a trusted auto parts store or a mechanic; they can help determine the best coolant for your vehicle's specific needs based on its age and the condition of the cooling system. Improper coolant can lead to corrosion and damage to your engine.
