15 year old dex cool

Replacing dexcool every 2 years is a waste, but to each
his own

Where did you get two years from?

It is pretty standard 60 months or 241,401.6 kilometers.

How difficult is it? Dexron spent who knows how much time and effort to (apparently) make a coolant since 2yrs/24,000 miles apparently wasn't doable for us. Now, we cant even keep to a 5yr/100-150,000 mile interval?


Who is this Dexron? I liked the old green coolant. Too bad it seems to be disappearing.

Just don't use it in Dexcool vehicles. People who love that green stuff and changed it out to the green stuff, paid dearly in the end.

I have a PDF from Havoline that states that even after 5/150 the corrosion inhibitors in Dexcool were still at 95%. And still passed the corrosion tests required for new coolants at 200k . http://www.taligentx.com/passat/info/fluids/Texaco-Havoline_DEX-COOL_Extended_Life_Coolant.pdf

Dexcool can go the life of the vehicle IMO, or change it when (if) you have to replace a part

My GF has a 2001 Buick Century 3.1 65K, lives and travels frigid rural road here in th MI.UP..original DexCool..What could be the harm in changing it with fresh DexCool?
