Alright you guys, I'm still confused about my coolant. DMC Joe says it's okay and Mike S. says that the acidity stuff is eating away at my aluminum engine. If that were the case shouldn't my car be in D heaven by now after 18years? Again, Don didn't recommend that it be changed either. Let's say that I take the safe road and have my local mechanic do the job for me. Is there anything special about the D that he should know before the flush and fill or is the system pretty generic? I'm torn between "if it ain't broke, don't fix it" and "an ounce of prevention is worth a pound of cure". Please advise and we might all learn something once again about these mysterious cars. Thanks again.
