I love my monte carlo 2002...but I bought it used in dec. 05 and started smelling coolant in 2008 then in 2010 steadily always having to add water..took it to shop and they did a pressure test to try and find where I was loosing it from but they found nothing....Its a nice ridding car but all this adding coolant every 2 days is a pain in the rear especially being no one can tell ya what's wrong with the car to get it fixed.....
