After some searching, I haven't been able to find anything anywhere on this. But ours had a leak in the back heater part. Dirty coolant and lack of coolant services can contribute to this. When driving, the temps are erratic at best. When it comes to your Nissan Pathfinder, you want parts and products from only trusted brands. Has enough leaked out yet that your coolant level in the radiator is low? It's also entangled with numerous connectors and bits of the wiring harness. So, the good news is that I'm not dribbling coolant but good tip of yours about carrying a gallon of distilled water.
Chuck Chuck - Thanks for the quick reply. The heater core itself is far forward in that box. The dimensions listed by Advanced Auto Parts are not the overall dimensions of the heater core. He had them patch it out of the system. A few weeks ago it started showing the telltale signs of a leaking heater core. My heater core started leaking several months ago, so during the summer I plugged both the inlet and outlet.
Could you please point out where that is? If low this is an indication heater core is leaking. And if you top up the rad, there are one and maybe two vents you need to open while topping up. Not trying to dissuade you, just letting you know it can be a bear! It may not of leaked enough to tell but usually these are the only reason the vents would smell unless a rodent ended up there and died. I'd estimate that the entire job would take a full day. What happens is the evaporator which is located in the vents never dries out and you begin to grow mold.
If it does have the cooling system flushed to remove the rest of the contaminates from the cooling system. Last night I had the driver side set on 70, and passenger side set on 74. If the part is right for you I would have no hesitation in recommending this part. If the coolant where to get too low the heater core would starve for hot coolant at idle. Heater cores can be a real pain. There's a post on it here in the Nicoclub forums. On a positive note, this replacement exchanger is solid metal!

Example: driver side set to 68, passenger side set to 74. The airbag warning light on the instrument cluster was flashing after reassembly. The lever will now scrape on the housing, but not severely enough to damage it. The lever will still move and work. Driver side blows really hot air, passenger is cooler. He damn near got frostbite. Their high-performance heating coils deliver excellent results and raise lukewarm air to the temperature you need to stay comfortable on the road.
The hardest job they had was getting the air bubbles out. Anyone have an idea where I should start looking? So many screws to keep track of, so many electrical connections to be pulled apart, so much plastic to break. Aftermarket Pathfinder heater cores from AutoZone are built to handle excessive use. On the other hand, my dad told a story about a car that didn't have a heater in a midwest winter in the early 1940s. Bottom Line recommended Advanced Auto Parts states there Heater Core Replacement part number 399174 is the exact fit for a 1995 Subaru Imprezza with the 1.
Sep 07, 2013 There are a couple of possibilities. The heater core may be plugging up. Had to modify the installation as follows: You will need to take the hot water valve off from this part and turn it around. This replacement heat exchanger is also smaller than the original width wise. Also the original clamp fastener to hold the exchanger down will no longer fit and produce a gap between the body and the exchanger core. The coolant level may be low.
Wait a bit and see what somebody here comes up with. And carry a a gallon of distilled water with you, and keep an eye on rad level. Reassembly took another 2 hours. The hoses go right into tubes or pipes that are soldered to the heater core, so the hoses show you exactly where the heater core is located under the dash. If it is coolant, feels slippery and smells like it? I will post my results from the dealer. Read it and see if you want to do it-on some cars or models, it is easy, there is a cover plate to remove and then slide the core out.
