Thats because the issues with DEx weren't DEx issues, they were engineering issues. In your Century they were fixed in 04, and in the Sabre in 05.

Any Dex before that you will get a gasket sludge-0-matic!

We run a fleet of GM vehicles and routinely run them from brand new to COMPONENT FAILURE in the cooling system. This is generally in excess of 200k miles or much more, regardless of time.

Some are sealed systems, some are not. The radiators are always sparkling clean and shiny, and the heat exchangers are too.

Before Dex it was routine for us to replace water pumps at 100k+ miles. There is a great deal of "Internet amplification" with regards to Dex on this and other forums.

Do not let common sense and experience speak your behalf. "Men" do not like it because it is pink.

I've never had a problem with Dex-Cool.

Hey, my Mopar G-05 and Toyota SLLC are both pink, and I like them just fine! It's the red Deathcool that causes problems-and lack of PM and monitoring coolant levels, along with uneducated mixing of coolant top-offs, and plastic gaskets that cause most of the trouble.
