I have a 1998 Pontiac grand am with over 200000 miles. I accidentily put dextral antifreeze in my radiator when I had a generic brand antifreeze all ready in there.is this all right or will I have problems.if so do I have to flush out the radiator and how do I do this?
there is no problem...as long as it's ethylene glycol and not tap water...you'll be alright...congrats on the maintenance, btw~
Mixing them really does not create any serious problems, OTHER than the coolant looses it's extended life properties. So it will need to be treated as conventional "green" coolant as far as service intervals are concerned.
