Used Cars: 2004 Chevy Malibu, 2004 chevy malibu, gasket leaks

Question
We purchased a 2004 Chevy Malibu with 57K miles on it three days ago. Our salesman suggested that we have the dexcoolant fluhed out of the system of our recent purchase.  He siad that Chevy knows that there is a problem wth dexcoolant because it was deteriorating internal gaskets.  Is this true?  Should we have dexcoolant removed or should we leave it as is?  We have only had the care three day and this is a concern to us.  The salesman has promised to remove/flush out the dexcoolant for us.  Should we have him do so or not?

Answer
Well here is what I would do.  It just seems fishy in my opinion that the salesman suggested you do that, if it needed done, then why wasnt it done before it was made available to sell.  My first thought when I started reading this was that he was trying to cover up a different problem, being an intake gasket leak.  The malibus are INFAMOUS for intake gasket leaks, and if it is the 3100 v6, your chances just massively increased.  Not being active in a chevy new car dealership, I am unaware of a problem with the dexcoolant, however, it would make since, because a bunch of chevy cars have gasket problems, however, you need to speak with somebody in a chevy service department.  If you are buying this car from a chevy dealership (new cars), the service department should know what they are talking about, now if you are concerned that somebody may try and hide something from you if you do it at that place, make a phone call to a different chevy dealership, and see what they say about the dexcoolant.  If all is like it should be about the dexcoolant, go ahead and let the dealership flush it for you.  I am just curious why a salesman knew of this, yet it had not been done before it was put on the lot.  And there may be a legit reason, just curious as to why.  I would definetly, definetly, definetly, be very firm and point blank with this salesman, dealership, manager, or service writer that you would like some type of a gaurantee that your intake is not leaking right now.  Because that is not a cheap repair, and if it does not get caught in time, can cause some major damage.  I think you will find this to be extremely helpful in protecting yourself.  Happy Holidays.
