Partially drain the coolant so it is below the thermostat, about half a gallon should do it, then follow the upper radiator hose to the thermostat housing, remove the two bolts, leave the housing attached to the hose, and pull it from the block.
Remove the old thermostat, remove the old gasket install the new one with the spring facing the block, snug the bolts evenly, the housing can and will crack if you do not, refill coolant, and your done!

Hi Merlin and Doug,

Sorry for the long lapse before this reply, but I am just looking to do the same repair now. Are you sure that is the procedure for the V6? I have a Haynes manual and it says that you need to remove the fan, drive belts and radiator and that the thermostat is connected to where the lower radiator hose terminates. Hopefully your procedure is correct though. Please let me know if you have any additional information.

Thanks,
Stephen

Mitchell tech line says follow upper hose! Right between the two cams in the center, on top!

Thanks for the feedback Merlin. It looks like we were both right. The thermostat is on the top, but to get at the housing you do need to remove the drive belts, fan shroud and fan and radiator.

Where and how do you replace the thermostat in this pathfinder? The area is so small. Also, I would like to find out how you would fix the gas gauge and temperature gauge? Could it be a fuse or would it be something else? I do not want to drop the gas tank to fix a problem that would not be necessary.

Drain the engine coolant into a clean container, so that the level is below the thermostat housing.
If necessary, disconnect the upper radiator hose at the water outlet.
Loosen the securing nuts, then remove the water outlet, gasket, and thermostat from the thermostat housing.

When installing the thermostat, always use a new gasket with sealer and make sure the thermostat spring is facing the inside of the engine. The water outlet housing on VG30i and VG30E engines has the letters UPR and an arrow embossed on the flange edge; they should always be pointing up. The KA24E, VG30i and VG30E engines have a jiggle valve on the thermostat which should always be facing up. Water outlet mounting screws should be tightened to 12-15 ft. Lbs. (16-21 Nm) on all engines but the KA24E, which should be tightened to 5-6 ft. Lbs. (7-8 Nm). Refill and check the coolant level.

What problem are you having with the fuel and temperature gauge? Are they inaccurate, not registering at all, sticking etc.?
