can i use anykind of antifreeze in 2005 buick

We have ethylene glycol as our coolant....some are 50/50 glycol/de-ionized water....some have anti-bubbling agents in there...PEAK, Prestone, Xerex Dexcool....alll are pretty much the same...I'd look at cost here...unless you insist on enivironmental Propylene Glycol which is non-toxic~....must be changed frequently with the PET-safe stuff~

must be dex cool.. if you switch you must thoughly drain the dex- cool out.

Use the dex. It doesn't thicken with age (plug up your radiator). It is good for 5 years. It is what GM recommends for the car.

I still don’t know know what to use.

Ok del cool it's best for a 2004 Buick LeSabre?

Use any kind. Flush first and DeX cool does has clogged my heater core.

Im using green considerate. coolant for my bucik lesebre and its overheating got a new radiator and water pump ... Still overheating is it because i put green coolant
