ImpalaWhile undergoing many facelifts in its history, the Impala has proved itself to both civilians and police forces as one of the most capable 4-door cars GM has ever offered. Currently moving towards its 10th generation the Impala is one of the longest lasting and popular models.
If you keep a tight cooling system, the Dexcool should go 150 like they advertise. No problems with mine so far (my 2000 Malibu was a different matter, but she's in the graveyard now). The Transmission fluid is Dextron VI (synthetic) and might be pricey to change. Did mine when I bought car (for that good feeling you get with new stuff), but it looks and smells new at 70,000+. Unless you really dog it, it's an expensive investment. If you still want to do this, buy the good stuff and get an new filter with good gasket. And for gods sake, don't over tighten the pan bolts. Helpful? probably not, but my opinion anyway.
"I USED TO CARE".......but I take a pill for that now.
