Going to swap my thermostat on my 01 Ta, do i refill with just Coolant? Or 50% DEX Coolant & 50% Water?

Use 50/50 dexcool or any HOAT (semi organic)

or use distilled water with full strength coolant mixed to 50/50.

or fill back up with straight distilled water and pour a bottle of Redline water wetter.

Personally I use O’reilly gold bottle mixed with distilled water and I add the bottle of water wetter.
