SOURCE: Hi, I have a 2001 nissan
hi. was just looking at your problem of (sentra) overheating and actually, i am a mechanic for nissan and have changed many head gaskets for this particular vehicle equipped with 1.8 liter motor and found that they are notorious for this problem of faulty head gasket's.Unless you did't properly bleed the system,which i doubt because you seem mechanically inclined since you already changed every other part of the system,i would't doubt that this is the problem.Anyway, by the time you read this, you have probably already found this out..Just thought i would let you know this info.Good luck!...by the way,if you haven't already changed you cam and crank sensors,do that too,before you get stuck and get the part's at the dealer!!!!-they are redesigned from the old one's!!just some advise to try to help you out!!!

I had this exact problem a few weeks ago. The repair shop first changed the thermostat. Didn't fix the problem. Next step, they found the radiator was clogged. They replaced the radiator and now everything works fine.

SOURCE: no heat just changed thermostat
sounds like you did not refill the system properly. right above the thermostat housing is a single screw with copper washer. you need to take this screw out before re-filling cooling system. that screw allows air to escape from the engine while re-filling coolant. you have an air pocket in system.

unfortunately these engines are known for this condition and for head gasket failure.with engine cold pressurize cooling system with spark plugs removed.look down into holes with flashlight after about ten minutes.....im betting youll see a puddle of coolant on piston...usually its cyl# 2 or 3.i cant think of any other possibility for system repeatedly airlocking other than a head gasket.good news they are probably one of the easier ones to replace.
