My name Stefan P. New to Nissan and Pathfinder .I just purchased a 2006 Pathfinder.153,900.00 Miles.2 Issues Heat does not seem to work.Blows cold out of vents and defrost area.All controls working. But seems to get warm when moving.Second ,How do I know if I may have trouble with radiator leaking coolent into transmission? Also is coolent only checked in side resevour? Or should I see coolent in radiator too? I removed the cap and didnt see any flowing as engine was running.Thank you for your time.

We looked at the 2005 and 06 Pathfinders over a year ago for my son. They are nice but were just a little too much. As part of our research we learned about the leaking radiator into the transmission fluid. The trans fluid runs through a heat exchanger in the bottom of the radiator like many cars, but the Nissan radiators are defective and will eventually leak. If your fluid is clear and it is shifting correctly you are lucky, but you should run a separate trans fluid cooler as a bypass for the radiator cooler. These are about $100 and easy to install. Or you can replace the radiator, which is quite a bit more.

Funny(sad) but a friend had a perfect, always garaged, 2005 PF and the trans failed at 120k miles. He had to trade it in and only got $2200 for it. I would have bought and fixed it for a couple thou, but don't have a place to work on it.
