I would like to add antifreeze to my Alero. the cap says only use one type of antifreeze. If I don't drain it, do have to use that type or can I buy the prestone stuff that can be mixed with anything?

thanks in advance,

Ray

Using anything but Dexcool in your system will void the warranty on the vehicle (assuming you have one). The "One Bottle For All" you could add, but it is recommended only as a top off fluid, not a complete change. Do not mix Dexcool with the "green" stuff or you will have major problems.

Suggested Repair

Use Dexcool when adding coolant. A universal all-makes coolant may be used only to top off, not for a complete change. Do not mix Dexcool with conventional green antifreeze.

Conversation Summary

The owner of a 2002 Alero asked whether the specified antifreeze must be used when adding coolant without draining, or whether a universal Prestone product that mixes with anything is acceptable. The expert said anything other than Dexcool can void the warranty, that universal coolant is suitable only as a top-off and not for a full change, and that mixing Dexcool with green antifreeze can cause major problems.
