Currently has the traditional green stuff and I will be doing a complete flush so I can start from scratch. Will not be using the same old school green as I want something with longer life. This 1995 was a split year with the early cars getting the green coolant before changing to Dexcool later in the year. Any reason I can’t switch it to Dexcool? Or are there any green color long life coolants that would work? Like the green Asian formula POAT from Peak for example? Another option may be something like Prestone Platinum All Vehicle coolant. And do I still need to add those sealant tablets with these modern coolants?
