due to Dex Cool coolant? I have a 2003 Buick Century with v-6 engine. Are there any stats available on engine gaskets that have had to be replaced due to Dex Cool antifreeze? I just changed mine and put the regular green antifreeze in it. Is this ok??
 
All the research done on Dex cool shows it is when the system is low on coolant for long periods of time. Maintain you cooling system and you will not have problems.
 
The intake gasket is a common leak on those when you replaced what gasket did you get? Felpro or OE are best as theyve redesigned the gasket. I've seen a number of these go bad i think this last summer alone we had to replace 4 or 5 of em at the shop i work at. As far as swapping antifreeze as long as you got all the dex cool out itll be fine to run the other stuff. But if you mixed em expect problems later on as they dont miss well and can cause more problems. And yes the dex cool was the cause it eats away at the gasket and the intake some of em had plastic intakes if yours does did you check it before putting it back on? We had to replace 2 intakes completely when we redid the gaskets.
 
I agree with Mike, I have never had a problem with dex cool on any vehicle I owned because flushes get done when they are supposed to.
'03 Century, when and how often have you had cooling system flushes performed and do you have receipts?
