My friend just bought an 04 Dakota 4.7 Quad Cab and the only really bad problem with it so far is that you can definitely smell coolant with the heater on. However, there is no sign of dried coolant or wet coolant on any part of the floor. The heater core where the heater hoses pass through don't appear to be wet either. The window didn't fog up either. I know on my 99 R/T it had a bad heater core and the window fogged up and the floor was wet. On an 04 with the restyled dash do you still have to remove the entire dash to change the heater core?
