Hey.
The reason why your engine is over heating is 1.),Your engine has dirt and other gunk in it, or,2.)You need a new filter, or3.), your engine doesn't have a filter and you need to get one. The filter I recommend is the filter with the orange micro-fibers in it. I do not remember the name of it offhand, so I'll try to get back and tell you.

it can be many stuff but in your place i would check first the coolant level and the thermostat
To keep the car engine from over heating
your car is over heating
If it is not actually over heating, then if the smell is outside the car, look for coolant leaks around the head and the thermostat cover. Inside the car could be a leaking heater coil.
If your car is over heating you may want to check your thermostat and replace it may solve your over heating problems
It sounds like its over heating

yes the water pump would be bad if its evaporating the water very quick.
If your Pathfinder is over heating then you may have an issue with the coolant. You can try adding more coolant to ensure that your car is no longer over heating. You can also double check to make sure your blower is actually cooling your engine.
Usually heating is done by passing air over the hot engine so no extra fuel (gas/petrol) is used.
If you need a heater core, the one you currently have would be leaking. If the car is over heating or not getting warm enough, think thermostat.
