I've got a 97 3.4. It's loosing coolant and it seems to be getting worse. I've added almost 7 liters in the last 3 months.
I can smell coolant in the cab while driving so I suspected a bad heater core, but the floorboards are bone dry. Theres no visible leaks. oil looks fine.
I pulled the codes and its not missing (only code was intake air temp circuit). It dose idle rough on start up for a few seconds then its fine, and some white smoke as well.
Any input would be greatly appreciated.
