If you have an 05 Pathfinder check the rigid pipes that run from the front of the car to the rear heater matrix.
The design of these is ridiculous and they corrode through resulting in coolant dripping out over the rear of the car.
The place to look is just behind the rear offside wheel (easier if you take the wheel off) I noticed this when changing rear brake pads on my low mileage 05 T-Spec. You will see where the two pipes are retained together that road salt is trapped and the thin walled aluminium tubes rot through.
Mine have just failed and Nissan want over £1, 000 to replace them!!! The job requires that the body be lifted from the chassis to gain access to the pipes. What a poor design feature on a not inexpensive vehicle!!
CHECK YOURS ASAP!!!!
