thirdtbird Um it's in the title for my post, i left out Nissan , thought everyone would know that.
Crusser i bought it used, looking at the radiator it looks original, the car has 184k miles. , yes new cap and thermostat. someone told me to put the car in the over temp w/o going into the danger zone , and turn on the heat, if i get heat the water pump is good. i bought the car cheap, had a blown head gasket. i took the head off, was not warped, used a straight edge and feeler gage all in specs. chemically checked for cracks cleaned off the top of the block reassembled. whoever had it at one time used advanced auto's copper seal. supposed to take the thermostat out. i don't think they did, the thermostat was a bright copper color so i put in a new thermostat. yes i believe all the air is bled out used this

yep i think its a cooling issue now too i am thinking whatever is wrong is what got the original owner. it's quite possible that you did did i ask the same question ? should i look for the post, think it's the rad. i bought the same year Nissan altima..has the 2.5L i took off the upper hose and the radiator inlet pipe crumbled. put in a new radiator ...uuugh plastic radiators, intake manifolds ( saw one explode , timing off or a stuck open intake valve) valve covers.. what are they thinking ?
what i think it might be is the actual neck of the radiator. i can sometimes smell that " pancakes and syrup" smell around the cap...the cap is new. oh BTW thanks for answering again
