I just bought a third contour (for my daughter) and it has discolored coolant (dark brown in the overflow bottle) and the trans fluid appears thin. I'm assuming it a leak in the radiator/ Trans cooler but I don't see any real oil bubbles etc. Any test to confirm would be a help. I am also going to replace the water pump (2.5L motor) but I forget what is the preferred color for the improved impeller design.
Thanks,
Mike
