Question about 1995 Nissan Sentra
Heating problem on hill I done the head and changed water pump
Did you change the thermostat. It might be stuck halfway open. When you start to go up a hill, the engine heats up more, the thermostat needs to open more, to let more coolant by to the radiator.

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!!!

sounds like you have a thermostat problem also did you bleed the cooling system of all the air before you put the radiator cap on?
if you have not bleed the system and there is a air lock you will have over heating problems.
the way you can try bleeding the car is let it get up to temp with the rad cap off and let the fans cycle twice and wate till all the air bubbles stop stop coming out.
if the air dosn't stop coming out for a long long time you may have a blown head gasket

Simple thing to test first would be to pressure check the radiator cap. Next would be to check for combustion gases in the radiator indicating a leaking head gasket. It is an aluminum head and iron block engine and there is a possibility that antifreeze anti corrosionpackage runs out due to over age then fails due to too long in the engine it results in galvanic corrosion at the head gasket-commonly resulting in a failed head gasket. There are other engines that are vastly more prone to this than the maxima engine. If there is a leaking head gasket the gases could rise to the top of the system and block the water flow into the heater. Listen for gurgling sound in the heater.

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.

when you changed the therm you let air into the system and it will usually cause a air bubble in the heater core you probally should try to burp the system there is usually a plug or a relief valve check with your dealer fro instructions on how to burp the air out of the system try that first befor4e trying to replace the heater core
