    I'm basically experiencing the same exact problem. I have a 2003 Sentra 1.8 GXE and it has been overheating on me as of late and the heater works sometimes only. I did a pressure check and it came out good and there are no leaks of antifreeze and my i have plenty of anti-freeze within the tank and radiator itself. I changed the thermostat but my car overheats more now! Please help, anyone???

    I have the same symptoms in my 2003 Sentra GXE, 1.8 L manual, 120'000 miles. This morning, the heater did not work, and the temperature gauge fluctuated up and down wildly, almost hitting top temperature. The temperature indicator seems to tend to go up when the car is standing mostly.

    OK, same guest as yesterday. My garage told me it was due to a broken thermostat, which I had replaced. Apparently, the head gasket in the Sentra really does not like overheating, so when it malfunctions, this is usually because of some underlying problem with the temperature regulation mechanism. I suggest to everyone experiencing this problem to BRING YOUR CAR IN FOR REPAIR IMMEDIATELY. A new thermostat runs around $ 200; replacing a head gasket easily comes to $1000 to $1500. Definitely not worth the risk.

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.

Does the car overheat at idle or travelling down the road? if the thermostat was not changed, thats first step. checking it is replacing it. possibly air-bound. then i would suspect a headgasket problem.

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

Engine overheat and no heat


Maybe your radiator is clogged.

2003 nissan sentra no heat, over heating


If the engine has overheated, chances are pretty good that you now have a warped or cracked cylinder head and a blown head gasket. Those engines are very unforgiving when it comes to being overheated.

1995 Nissan Sentra GXE Overheats (Temperature rises to near max, not spewing) only when at idle. The Radiator fan works (at least it spins) I swapped relays, too and still same problem. Both fans work...


are the upper and lower radiator hoses hot when car overheats? if so check for a clogged radiator or weak water pump. if one hose is hot and the other is cold or much cooler then replace the thermostat.
