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.

2005 Nissan Sentra overheating. Changed the water pump. Did a radiator flush. What else could it be??


Some thing too check:
Make sure coolant level is up to line and clean (not dirty, do to clogged radiator, may need to be flushed or replaced).
Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .
Make sure fan is working properly equip t (is not running too slow). Or Manual (belt driven) fan clutch is working properly, not loose or spinning too freely?
Check for broken or cracked fan blades itself.
Check radiator cap, (no gasket tears).
Could be thermostat going bad ?
Could be coolant temperature sensor/switch (from computer) going bad?
Check radiator hose(s) (too soft, may collapse)?
In some rare cases:
Timing could be off.
Could be water pump.
Could be blown head gasket(s).
Could have cracked head(s).
ECT..............Hope this was some help???

2003 nissan sentra gxe-car won't start at times it rolls over but won't fire up had all kinds of diagnostic tests run and can't find anything wrong-plus just replaced thermostat, spark plugs and i keep...


It you're losing coolant and it overheats, that's a sign of a bad head gasket. Get that checked before you spend any more time or money on anything else

2003 Nissan sentra 2003 gxe, had 4 yrs, no problems, blows cold air only, had lines flushed to remove air, thermostat works fine, is it the head gasket?


Start the car up when it is cold and rev the engine up for 30 seconds,loosen up the radiator cap and see if there is pressure there..If there is you probably have a bad head gasket...Caution do not open cap if engine is warm...

then the water pump must be bad in it .Take the rad cap off and rev motor up if it goes down the the pump is working if it spays of look at the head gasket being damaged .Check and make sure spark plugs are not wet either if one is soaked signs of a leaky head gasket

2003 Nissan Sentra Problem overheating and heater doesn't work.


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.

Hi, I have a 2001 nissan sentra gxe that is overheating. I have changed the thermostat, water pump and flushed the radiator. The radiator does not have a leak in it, but the car is still over heating. ...


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!!!
