i found out why my 2000 frontier was over heating after a year of trying to figure it out............timing belt was put on back wards from the orginal owner and im the 3rd owner but it was  making the water pump  pump in reverse and i also changed the head gaskets and everything and its running great!!

EDIT:

Thanks for the update info... But I doubt that the timing belt could have been  backward as seen below:

Probably one of these:

Seems like the fan would also run backward with the water pump... but maybe I just need a little more sleep...

  Thanks again..
